Detailed ways

The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

Embodiments of the present application provide a vehicle data transmission method, device, vehicle, and computer-readable storage medium. The embodiment of the present application will be described from the perspective of a vehicle data transmission device. The vehicle data transmission device may be integrated into a computer device. The computer device may be a terminal device, specifically a terminal device carried on a vehicle (vehicle). , that is, a vehicle-mounted terminal; in addition, the terminal device can also be other types of equipment, for example, the terminal can be a TV, a smart phone, a tablet computer, a notebook computer, a desktop computer, a smart speaker, a smart watch, a smart wearable device, etc., these Equipment may be placed in a robot or vehicle in a non-integrated manner; but is not limited to such.

For example, refer to FIG. 1 , which is a schematic diagram of a scene of a vehicle data transmission system provided by an embodiment of the present application. The system is applicable to a scene of vehicle data transmission in a vehicle system, and the scene may include a terminal.

Specifically, the terminal may be a vehicle-mounted terminal, which is specifically used to obtain the message to be sent corresponding to the vehicle data, and transmit the message to be sent to the message buffer space, and the message buffer space is a storage space for storing untransmitted data messages Space; prioritize the messages to be sent in the message buffer space to obtain the message priority sequence; send the messages to be sent in the message priority sequence to the message transmission channel; detect the message transmission channel A target feedback message corresponding to the message to be sent; executing a message response policy corresponding to the target feedback message.

For ease of understanding, the following examples will briefly describe the application scenarios of the vehicle data transmission method, as follows:

Exemplarily, the vehicle controller is used as the vehicle terminal, and the data message of the vehicle controller is taken as an example. Specifically, the vehicle terminal can obtain vehicle information such as gear control, braking, stepping on the accelerator, stepping on the clutch, air conditioning temperature control, etc. Data, and generate messages to be sent based on any of the above vehicle data; furthermore, in order to avoid messages with lower priority occupying the storage space for sending and receiving messages, a message buffer space can be created in advance, and each message to be sent transmitted to the message buffer space, and sort the sending priority of each message to be sent in the message buffer space; then, according to the sending priority order among the messages in the message priority sequence, the messages to be sent are sorted The file is uploaded to the message sending and receiving storage space, and after the received message to be sent is sent to the message transmission channel (such as CAN bus) in the message sending storage space, continue to send the next message to be sent in the message priority sequence The message is uploaded to the message sending storage space until all the messages to be sent in the message priority sequence are uploaded. For each message transmitted to the message transmission channel, it will be received by the message responder that meets the response requirements and respond, for example, the vehicle power subsystem receives a data message for gear position control and responds. It can be understood that, after responding to the received message, the message responding end may return a response result message to the message transmission channel. At this time, the vehicle-mounted terminal can detect the target feedback message corresponding to the data message of gear position control in the message transmission channel, and execute the message response strategy corresponding to the target feedback message. For example, the vehicle-mounted terminal receives the vehicle power subsystem For the target feedback message of the gear position control, respond through response strategies such as the speedometer and voice prompts for gear shifting to prompt the driver that the gear shifting operation is successful.

Each will be described in detail below. It should be noted that the description sequence of the following embodiments is not intended to limit the preferred sequence of the embodiments.

In the embodiment of the present application, description will be made from the perspective of the vehicle data transmission device, so that the vehicle data transmission device can be integrated into a computer device such as a terminal device or a server. Referring to Fig. 2, Fig. 2 is a schematic flow chart of the steps of the vehicle data transmission method provided by the embodiment of the present application. Taking the terminal device as an example, the terminal device may be a vehicle-mounted terminal, and the processor on the terminal device executes the corresponding method of the vehicle data transmission method. During program instructions, the specific flow of the vehicle data transmission method is as follows:

101. Obtain a message to be sent corresponding to the vehicle data, and transmit the message to be sent to a message buffer space.

In the embodiment of this application, the vehicle system includes data information interaction between multiple terminals. In order to improve the quality of the vehicle and reduce the transmission medium used to transmit vehicle data information, various vehicles can be transmitted through a general transmission channel. Data information, where the data information may be transmitted in the form of a data message. However, in order to give priority to providing transmission resources for messages with high priority, the messages corresponding to the vehicle data information can be transmitted to the message buffer space for sorting, so that the messages of each vehicle data information can be transmitted in the order of sorting.

Wherein, the vehicle data may be information data in the vehicle system, taking vehicle control data as an example, the vehicle data is not limited to information data including gear position control, braking, speed up, deceleration, air conditioning control, etc.

Wherein, the message to be sent is the data transmission unit of the vehicle information data in the vehicle system, and each message represents a complete information data, and the lengths of different messages may be inconsistent, depending on the complete information data actually included. Determined, such as according to the amount of information data. It can be understood that, among the control units in the vehicle system, the information data transmission between the control units can be realized in the form of data packets.

It should be noted that due to the limited resources of the hardware configuration in the vehicle system, such as the limited storage space resources in the vehicle chip, and the amount of information data that needs to be transmitted between the control units in the vehicle system is large, that is, the number of messages is large , and the vehicle-mounted system has a priority characteristic when transmitting messages, which will cause the messages to occupy storage resources in the hardware configuration, causing the vehicle-mounted system to be heavily loaded when dealing with these information data. In this regard, the embodiment of the present application creates a message buffer space by means of software, so as to sort the data messages in the message buffer space before the data message is transmitted, so as to transmit the messages according to the sorting result, Prevent low-priority packets from occupying storage resources in the hardware configuration.

Wherein, the message buffer space is a storage space for storing untransmitted data messages. Specifically, before the message is transmitted, each message that needs to be transmitted can be stored in the message buffer space, so that the subsequent Sequenced for transmission. It should be noted that the message buffer space may be in the form of a buffer array, and its size may be larger than the total number of messages to be sent.

For ease of understanding, the cache array will be used as the message cache space for description. As shown in Fig. 3, the cache array contains multiple message buffer areas, each message buffer area has an identifier, such as "0x100", "0x110", "0x200" ... "0x320" and so on, Each message buffer area is used to store a data message, from the message buffer area "0x100" to the message buffer area "0x320", the cache group identifiers among multiple units are sorted from small to large.

In order to ensure that the size of the message buffer space can accommodate the data messages to be transmitted, it is necessary to create a buffer array with sufficient capacity in advance. The number of message transmissions in the historical time can be used as the basis for creating the cache array. Specifically, the message transmission records of the historical time are obtained, and the message transmission demand within the target time is determined from the message transmission records. According to the report Determine the target number of message buffers based on the demand for message transmission, and create a cache array containing the target number of message buffers. In addition, each message buffer area can also be marked by the cache group ID, and sorted according to the cache group ID from small to large, so as to obtain a cache array with a sort relationship.

In the embodiment of the present application, after the vehicle-mounted terminal detects the vehicle data, it can generate a corresponding message to be sent according to each vehicle data, and then send the message to be sent to the message buffer space, so that it can be passed through the buffer later. The array sorts each message to be sent.

Through the above method, the vehicle information data to be transmitted can be packaged in the form of a message, and the obtained message to be sent can be transferred to the message buffer space, so that the messages to be sent can be sorted and sent in the message buffer space .

102. Prioritize the messages to be sent in the message buffer space to obtain a message priority sequence.

In the embodiment of the present application, when the message buffer space contains multiple messages to be sent, in order to prevent the messages with lower priority from occupying the hardware storage resources of the sending unit of the vehicle system, the The multiple messages to be sent are sorted, so that the messages to be sent are sequentially transmitted according to the sorting result.

Wherein, the packet priority sequence may be a sequence including priority ranking relationships of multiple packets to be sent.

In some implementations, the message buffer space includes multiple messages to be sent, and the messages can be sorted according to message types. Then step 102 may include:

(102.1) Identify the message type of each message to be sent in the message buffer space;

(102.2) Determine the message priority relationship between multiple messages to be sent according to the message type;

(102.3) Construct a message priority sequence corresponding to multiple messages to be sent according to the message priority relationship.

Wherein, the message type may indicate the type of vehicle data in the message. It can be understood that the vehicle system contains many types of vehicle data. Take the vehicle controller as an example. When each information data generates a message, the message types corresponding to different information data may be inconsistent. In addition, a message can also be composed of multiple vehicle information data, and the difference in information data can lead to inconsistent message types. The first message, and when the speed needs to be increased, the second message of acceleration type is composed of clutch, gear position control, throttle and other information data, then the types of the first message and the second message are inconsistent.

It should be noted that, the type priority relationship between different packet types may be preset. Specifically, it can be determined according to the importance of vehicle data in the vehicle system. For example, if data packets of types such as deceleration, opening windows, and air-conditioning temperature control are included at the same time, driving safety photos can be taken as the first element, and user experience can be taken as the second. Two elements, then the priority relationship between the three types can be that the type of "deceleration" is greater than the type of "opening the window", and the type of "opening the window" is greater than the type of "air-conditioning temperature control".

Specifically, taking each message containing one vehicle data as an example, the type of the message can be determined according to the type of vehicle data in the message, so that the message type between the messages to be sent can be determined based on the message type. Finally, sort the messages to be sent in the message buffer space according to the message priority relationship to obtain the message priority sequence.

In some implementation manners, the packet priority can be determined through the magnitude relationship of the packet identifiers. For example, step (102.2) may include: according to the message type, determine the message identifier corresponding to each message to be sent; level relationship.

Wherein, the message identifier may be determined according to the priority relationship of message types. Specifically, the correspondence between message types and message identifiers is established in advance, and each message type has a corresponding message representation. For example, take vehicle acceleration, vehicle deceleration, window opening, air conditioner temperature control and other types as examples , different message identifiers may be preset for vehicle acceleration, vehicle deceleration, opening of vehicle windows, air conditioner temperature control, etc., so that the message identifiers are determined according to different message types.

In addition, the message identifier of each message to be sent can also be given by the identifier of the corresponding message buffer area in the cache array, and the mapping relationship between the message buffer area and the message type can also be constructed in advance, so that the subsequent The message type is used to select the message buffer area to be registered in the buffer array for the message to be sent, so that the message identifier of the corresponding message to be sent can be given by the identifier of the message buffer area.

Specifically, when determining the message identifier of each message to be sent, the target message buffer area of the cache array in the message buffer space can be selected according to the message type of each message to be sent, and the The cached group identifier of the buffer area is assigned a message identifier for the message to be sent; for example, the message to be sent is transmitted to the target message buffer area, and the cached group identifier of the target message buffer area is used as the message ID of the message to be sent. Text ID. Furthermore, the priority relationship among the plurality of messages to be sent is determined according to the small to large relationship of the message identifiers, for example, the smaller the message identifier, the higher the priority of the message.

Exemplarily, it is assumed that messages of vehicle acceleration, vehicle deceleration, window control, air conditioner temperature control, etc. are included, and the message of the vehicle acceleration type is identified as "0x100", and the message of the vehicle deceleration type is identified as "0x110" , the window control type message is identified as "0x200", and the air conditioner temperature control type message is identified as "0x300", then according to the relationship from small to large, the priority relationship of the above types of messages is as follows: vehicle Acceleration message, vehicle deceleration message, window control message, air conditioner temperature control message. The above are examples only, and are not intended to limit the implementation of this application.

Through the above method, before the message is transmitted, it can sort the messages containing multiple messages to be sent in the message buffer space, so that the messages to be sent can be transmitted according to the sorting relationship, so as to avoid the low-priority The message occupies the hardware storage resource of the sending unit of the vehicle system, which saves the hardware resource occupation of the vehicle data transmission in the form of software, and has reliability.

103. Send the to-be-sent packets in the packet priority sequence to the packet transmission channel.

In the embodiment of the present application, after the message priority sequence including multiple messages to be sent is obtained, each message to be sent can be sequentially processed based on the priority relationship of each message in the message priority sequence. transmission.

Wherein, the message transmission channel may be a data transmission channel in the vehicle system, which has a data connection relationship with each control unit in the vehicle system. For example, the message transmission channel can be a control unit local area network (Controller Area Network, CAN) bus in the vehicle system, that is, a CAN Bus or a CAN bus, and the CAN bus is respectively connected to each control unit (system) in the vehicle system for communication, such as It is connected with the vehicle power subsystem, car lighting system, car window system, air conditioning system, etc.

It should be noted that, in the process of transmitting the message to be sent, the transmission process of each message to be sent is regarded as a transmission round, for example, the transmission of a message to be sent from the message buffer space to the message transmission channel is regarded as For one transmission round, it can be understood that when multiple messages to be sent in the message buffer space are transmitted, there are multiple transmission rounds.

In some implementation manners, in order to effectively manage the message transmission process so that the transmission rounds are not affected and avoid being blocked during the message transmission process, each message transmission round may be managed. For example, step 103 may include:

(103.1) Identify the function state corresponding to the message sending function;

(103.2) When the function state is a sendable state, select the target message to be sent according to the message priority relationship in the message priority sequence;

(103.3) Based on the message sending function, send the target message to be sent to the message transmission channel.

Wherein, the message sending function may be a function for managing message transmission rounds, which may be understood as a transmission interruption function, which is used to limit the transmission of other messages to be sent during the message transmission process. For example, when transmitting the message to be sent with the first priority in the message priority sequence, the function state of the message sending function will be in the interrupt transmission state, that is, the unsendable state, which is used to limit the transmission of the second priority The transmission of the message to be sent at the first priority level, until the message to be sent with the first priority is transmitted to the message transmission channel, the function status of the message sending function is in the sendable state, and then starts to transmit the message to be sent with the second priority message.

Specifically, when multiple messages to be sent in the message priority sequence can be transmitted sequentially through the message sending function, before the transmission, the function status of the message sending function is first determined to determine that the function is currently transmitting other For the message, when the message sending function is in the sendable state, according to the message priority relationship in the message priority sequence, select the top-ranked target message to be sent from multiple texts to be sent. Then, the message to be sent by the target is transmitted through the message sending function. It should be noted that, during the transmission of the message to be sent by the target, the function state of the message sending function is the unsendable state, that is, the interrupted transmission state Specifically, the transmission process may be: using the message sending function to transmit the target message to be sent to the hardware storage space of the sending unit, and the sending unit transmits the target message to be sent to the message transmission channel. Further, after the message to be sent by the target is transmitted to the message transmission channel, the function status of the message sending function is in the sendable state. At this time, continue to select another target that is ranked higher in the text to be sent from multiple texts to be sent. message, and transmit the message to be sent by another target through the message sending function; and so on, until the last message to be sent by the target in the message priority sequence has been transmitted.

Through the above method, each message to be sent can be transmitted sequentially according to the priority order of the message, so that the data message with a higher transmission priority can be transmitted preferentially, and the data message with a lower priority can be effectively prevented from occupying the sending unit. The hardware storage resources reduce the load of the vehicle system when transmitting data messages, improve the transmission performance of data messages, and make the transmission process of multiple messages smoother and more reliable.

104. Detect the target feedback message corresponding to the message to be sent in the message transmission channel.

In the embodiment of the present application, after the vehicle-mounted terminal completes the transmission of the message to be sent, it may also receive a response feedback message corresponding to the message to be sent.

Wherein, the target feedback message may be a response message fed back by a corresponding control unit in the vehicle system. Specifically, the vehicle system includes a plurality of control units, and the plurality of control units are connected through a message transmission channel to realize the interaction of information data (messages) between any two or more control units; in order to facilitate understanding , the first control unit is used as the sender of the message to be sent, and the second control unit is used as the receiver of the message to be sent, then after the first control unit transmits the target message to be sent to the message transmission channel, the second When the second control unit detects that the target message to be sent is a message that needs to be received, the second control unit will receive and respond, and the second control unit will upload a target feedback message to the message transmission channel after completing the response , at this time, the first control unit may detect the target feedback message to be received and receive it for subsequent response.

Exemplarily, the vehicle system contains multiple controllers (units), and each controller corresponds to a control subsystem. After the user steps on the accelerator to control the acceleration of the vehicle, the vehicle controller will generate a message to be sent of the acceleration type. And transmit the message to be sent of the acceleration type to the message transmission channel, so that the vehicle power subsystem receives the message of the acceleration type, and then, the vehicle power subsystem responds to the information data in the message of the acceleration type After that, a response information data can be returned according to the response situation to inform the vehicle controller of the response situation of the acceleration event, such as how much to accelerate, and the feedback process is also implemented in the form of a message.

In some implementations, in order to reduce the load on message processing, the feedback message may be selectively received, so as to avoid the load of irrelevant data messages on the vehicle system. Specifically, step 104 may include:

(104.1) Determine the identification range value of the receivable message;

(104.2) Pull the message to be confirmed that meets the identification range value from the message transmission channel;

(104.3) Determine the message to be confirmed as the target feedback message corresponding to the message to be sent.

Wherein, the identifier range value may be a message identifier range value, which is used to limit the data packets that the local end can receive. Specifically, the vehicle system contains multiple controllers, which requires more data packets to be transmitted in the message transmission channel. In order to avoid confusion when each controller processes data packets, each controller can be pre-set Determine the available message identifier range value, and set corresponding message identifiers for different types of data messages in the vehicle system, so that the controller can detect acceptable messages according to the identifier range value. For example, the message identification range that can be used by the vehicle controller can be "0x100" to "0x320", and the message identification it can receive is "0x100" to "0x320"; in addition, the identification range value can also indicate the corresponding control The identification range of the message to be sent by the controller, that is, the identification range of the message to be sent by the vehicle controller is "0x100" to "0x320".

Specifically, determine the range value of the message identification used by the current vehicle-mounted terminal, detect whether the message transmission channel contains a message to be confirmed, and when the message to be confirmed is detected, identify the message label corresponding to each message to be confirmed , compare the message identification of the message to be confirmed with the identification range value, to filter the message to be confirmed that does not meet the identification range value, so as to avoid the current vehicle-mounted terminal from receiving irrelevant data messages and affecting the load of the current vehicle-mounted terminal and performance. Furthermore, the message to be confirmed conforming to the identification range value is determined as the target feedback message for reception and subsequent response.

Exemplarily, taking the vehicle controller as the vehicle terminal as an example, assuming that the message identification range used by the vehicle controller can be "0x100" to "0x320", when the message of the message to be confirmed in the message transmission channel The identification is "0x110", which conforms to the identification range value of the vehicle controller, and the vehicle controller can receive the "0x110" message to be confirmed. As another example, taking other identifiers as an example, assuming that the message transmission channel contains data messages of "1FF", "2FF", "3FF", "5FF", and "7FF", assuming that the message that the vehicle controller can receive If the range is "1FF~3FF", only the messages to be confirmed of "1FF", "2FF" and "3FF" are received, so that they can be used as target feedback messages later.

In some implementation manners, the feedback message corresponding to the message to be sent may be determined according to the type of the message to be confirmed. Then step (104.3) may include:

(104.3.1) identifying the identifier of the message to be confirmed corresponding to the message to be confirmed;

(104.3.2) Obtain the message identifier array, match the identifier in the message identifier to be confirmed with the message identifier array, and obtain the matching result;

(104.3.3) Determine the message type of the message to be confirmed according to the matching result, and determine the message to be confirmed as the target feedback message corresponding to the message to be sent of the message type.

Wherein, the message identifier array may be a message buffer array, which includes a plurality of message buffer areas, each message buffer area has a corresponding cache group identifier, and each message buffer area is used to match a corresponding type of message .

Since the message identifier corresponds to the type of the vehicle information data, after receiving the message identifier corresponding to the message to be confirmed, the vehicle-mounted terminal can use the message identifier corresponding to the message to be confirmed to determine the type of the message to be confirmed. Specifically, the message identification array is obtained, and the identification of the message to be confirmed is matched with the cached group identification in the message identification array through the dichotomy method, so as to speed up the matching process, and it is beneficial for the target feedback message to be quickly retrieved from the report. In order to ensure the validity of the message; when the matching result contains the target cache group ID corresponding to the message ID to be confirmed, determine the message type associated with the target cache group ID; The message is determined as a target feedback message corresponding to the message of the message type to be sent.

Exemplarily, taking the vehicle controller as an example, after the user steps on the accelerator to control the acceleration of the vehicle, the vehicle controller will generate a message to be sent of the acceleration type, and transmit the message to be sent of the acceleration type to the message The transmission channel enables the vehicle power subsystem to receive the message of the acceleration type, and then, after the vehicle power subsystem responds to the information data in the message of the acceleration type, it can return a message to be confirmed according to the response situation, At this time, the vehicle controller can receive the message to be confirmed, and identify the message type by matching the message identifiers of the message to be confirmed. If it is recognized as an acceleration type, it can be determined as the acceleration type The target feedback message for subsequent response.

In some implementations, the cached group identifiers contained in the message identifier array correspond to the range of message identifiers available to the vehicle-mounted terminal, therefore, the message identifiers can be constructed according to the range of message identifiers available to the vehicle-mounted terminal array, before "obtaining the array of message identifiers" in the step (104.3.2), it may include: querying the target message identifiers of a plurality of receivable messages; Obtain the message identification sequence; generate a message identification array according to the message identification sequence.

Through the above method, after the vehicle-mounted terminal completes the transmission of the message to be sent, it can receive the message to be processed from the message transmission channel, and determine it as the corresponding type of target feedback message through query matching, so that subsequent response.

105. Execute a message response policy corresponding to the target feedback message.

In this embodiment of the application, after receiving the target feedback message for the sent message, the vehicle-mounted terminal can obtain the message response policy corresponding to the target feedback message, and execute the message response policy, so that the vehicle system can Response, such as sending a reminder message to the driver.

Exemplarily, the vehicle controller is used as the vehicle-mounted terminal. After the user steps on the accelerator to control the vehicle to accelerate, the vehicle controller will generate a message of the acceleration type to be sent, and transmit the message of the acceleration type to the report After the vehicle power subsystem receives the acceleration type message and responds, it can return a target feedback message according to the response situation. At this time, the vehicle controller can query the corresponding target feedback message. Message response strategy, such as querying the information prompt strategy of the acceleration type, and prompting the acceleration result of the vehicle according to the information prompt strategy, such as broadcasting the vehicle speed, speed increase, and safety factor of the current speed through voice.

It should be noted that when multiple target feedback messages are received at the same time, in order to avoid confusion when responding to the target feedback messages, a correlation function may be used to sequentially respond to each target feedback message.

In some implementations, the target feedback message can be responded to through the message responder, and the message response process can be controlled in combination with related functions. Specifically, step 105 may include: identifying the execution state of the message response function; when the execution state is idle, sending the target feedback message to the message responder, so that the message responder executes the message corresponding to the target feedback message message response strategy; when the execution state is not idle, detect the message response progress of the message response end; when the message response progress reaches the preset progress threshold, send the target feedback message to the message response end, so that the message response The responder executes the message response policy corresponding to the target feedback message.

Wherein, the message response terminal may be a display screen, a voice announcer, a touch response terminal, etc., and each message response terminal stores a corresponding response strategy.

Wherein, the message response function may be a function for managing the message response process, which may be understood as a response interrupt function, which is used to limit the transmission of the target response message during the message response process. For example, when the target feedback message in the message identifier array is transmitted to the responder, the function state of the message response function will be in the interrupt response state, that is, the non-idle state, which is used to limit the target feedback message that needs to be responded next. until the function state of the message response function is in an idle state, and then transmit the target feedback message that needs to be responded to the corresponding message responder, so that the corresponding message responder executes the corresponding target feedback message Packet response strategy.

By implementing any one or combination of implementations in the embodiments of the present application, the application scenario of the vehicle data transmission process can be realized.

As can be seen from the above, the embodiment of the present application can obtain the message to be sent corresponding to the vehicle data, and transmit the message to be sent to the message cache space, and the message cache space is a storage space for storing untransmitted data messages; Prioritize the messages to be sent in the message buffer space to obtain the message priority sequence; send the messages to be sent in the message priority sequence to the message transmission channel; detect the message transmission channel and the message to be sent The target feedback message corresponding to the message; execute the message response strategy corresponding to the target feedback message. It can be seen from this that this scheme can first determine the message of the vehicle data that needs to be transmitted, and sort the priority of the message to be sent in the message buffer space, and then treat it according to the order relationship of the priority sequence of the message Send a message for transmission, effectively avoiding that the message with a lower priority occupies the space of the sending and receiving storage unit during message transmission. Finally, receive the target feedback message corresponding to the message to be sent, and execute the message corresponding to the target feedback message. In this way, the total amount of vehicle data transmission can be expanded to a certain extent to meet the transmission needs of vehicle data, improve the response efficiency of vehicle business functions, and improve user experience.

According to the methods described in the above embodiments, examples will be given below for further detailed description.

The embodiment of the present application takes the vehicle data transmission device as an example to further describe the vehicle data transmission method provided in the embodiment of the present application. Among them, Fig. 4 is a schematic flow chart of another step of the vehicle data transmission method provided by the embodiment of the present application, Fig. 5 is a schematic diagram of the architecture of the vehicle data transmission system provided by the embodiment of the present application, and Fig. 6 is a schematic diagram of the vehicle data transmission method provided by the embodiment of the present application A schematic diagram of a message sending scenario of a transmission method, and FIG. 7 is a schematic diagram of a message receiving scenario of a vehicle data transmission method provided in an embodiment of the present application. For ease of understanding, the embodiments of the present application are described in conjunction with FIGS. 4-7 .

In the embodiment of the present application, description will be made from the perspective of the vehicle data transmission device. The vehicle data transmission device may specifically be integrated in a computer device such as a terminal, and the terminal may be a vehicle-mounted terminal in a vehicle system. When the processor on the terminal executes the program instructions corresponding to the vehicle data transmission method, the specific flow of the vehicle data transmission method is as follows:

It should be noted that the terminals in the vehicle system may refer to the first vehicle-mounted terminal and the second vehicle-mounted terminal respectively.

201. The first vehicle-mounted terminal acquires a message to be sent corresponding to the vehicle data, and transmits the message to be sent to a message buffer space.

Wherein, the message to be sent is the data transmission unit of the vehicle information data in the vehicle system. Taking the vehicle (vehicle) controller as an example, the message to be sent can be brake, speed up, window control, air conditioning control or gear position Messages for control and other information data.

Due to the limited resources of the hardware configuration in the vehicle system, such as the limited storage space resources in the vehicle chip, and the amount of information data that needs to be transmitted between the control units in the vehicle system is large, that is, the number of messages is large, and the vehicle system is in There is a priority characteristic when transmitting messages, which will cause the messages to occupy storage resources in the hardware configuration, causing the vehicle system to be heavily loaded when dealing with these information data. In this regard, the embodiment of the present application creates a message buffer space by means of software, so as to sort the data messages in the message buffer space before the data message is transmitted, so as to transmit the messages according to the sorting result, Prevent low-priority packets from occupying storage resources in the hardware configuration.

Wherein, the message buffer space is a storage space for storing untransmitted data messages. Specifically, before the message is transmitted, each message that needs to be transmitted can be stored in the message buffer space, so that the subsequent Sequenced for transmission. It should be noted that the message buffer space may be in the form of a cache array, and the size of the space may be larger than the total number of messages to be sent.

Specifically, after the first vehicle-mounted terminal detects the vehicle data, it can package the vehicle information data that needs to be transmitted in the form of a message, and transfer the obtained message to be sent into the message buffer space, so that in the message buffer space sort and send the packets to be sent.

202. The first vehicle-mounted terminal identifies the message type of each message to be sent in the message buffer space, and determines a message identifier corresponding to each message to be sent according to the message type.

Wherein, the message type may indicate the type of vehicle data in the message. It can be understood that the vehicle system contains many types of vehicle data. Taking the vehicle controller as an example, the vehicle data can include gear control, braking, speed up, clutch, air conditioning control, direction lights, etc. Each information data generates a message, and the message types corresponding to different information data may be inconsistent.

Wherein, the message identifier may be given by the identifier of the corresponding message buffer area in the cache array. Specifically, the mapping relationship between the message buffer area and the message type can be constructed in advance, and then, according to the message type, the message buffer area to be stored in the cache array for the message to be sent is selected, so that the message can be passed The identifier of the buffer area is used to assign the message identifier of the corresponding message to be sent.

203. The first vehicle-mounted terminal determines the message priority relationship among the multiple messages to be sent according to the small to large relationship of the message identifiers.

Exemplarily, it is assumed that messages of vehicle acceleration, vehicle deceleration, window control, air conditioner temperature control, etc. are included, and the message of the vehicle acceleration type is identified as "0x100", and the message of the vehicle deceleration type is identified as "0x110" , the window control type message is identified as "0x200", and the air conditioner temperature control type message is identified as "0x300", then according to the relationship from small to large, the priority relationship of the above types of messages is as follows: vehicle Acceleration message, vehicle deceleration message, window control message, air conditioner temperature control message. It can be understood that the smaller the packet identifier, the higher the priority of the packet.

204. The first vehicle builds a message priority sequence corresponding to multiple messages to be sent according to the message priority relationship.

Wherein, the packet priority sequence may be a sequence including priority ranking relationships of multiple packets to be sent.

205. When the first vehicle-mounted terminal recognizes that the function state corresponding to the message sending function is in the sendable state, select the target message to be sent according to the message priority relationship in the message priority sequence.

Wherein, the message sending function may be a function for managing message transmission rounds, which may be understood as a transmission interruption function, which is used to limit the transmission of other messages to be sent during the message transmission process. The function state of the message sending function may include two states: sendable and unsendable,

Specifically, when multiple messages to be sent in the message priority sequence can be transmitted sequentially through the message sending function, before the transmission, the function status of the message sending function is first determined to determine that the function is currently transmitting other For the message, when the message sending function is in the sendable state, according to the message priority relationship in the message priority sequence, select the top-ranked target message to be sent from multiple texts to be sent.

206. The first vehicle-mounted terminal sends the target to-be-sent message to the message transmission channel through the message sending function.

It should be noted that during the transmission process of the target message to be sent, the function state of the message sending function is the unsendable state, that is, the interrupt transmission state. The purpose is to effectively manage the message transmission process, so that each message The transmission rounds are not affected, effectively avoiding the phenomenon of being blocked during message transmission.

Wherein, the transmission process is: setting the function state of the message sending function to a non-sendable state. Use the message sending function to transmit the target message to be sent to the hardware storage space of the sending unit, and the sending unit transmits the target message to be sent to the message transmission channel; further, after the target message is transmitted to the message After the text is transmitted through the channel, the function status of the message sending function is ready to send. At this time, continue to select another target to send a message from the multiple texts to be sent, and use the message sending function to send another message. The target transmits the message to be sent; and so on, until the last target message to be sent in the message priority sequence has been transmitted.

207. The second vehicle-mounted terminal receives the target message to be sent from the message transmission channel, and responds.

Specifically, the vehicle system includes a plurality of control units, and the plurality of control units are connected through a message transmission channel to realize the interaction of information data (messages) between any two or more control units; in order to facilitate understanding , with the first vehicle-mounted terminal as the sender of the message to be sent, and the second vehicle-mounted terminal as the receiver of the message to be sent, then after the first vehicle-mounted terminal transmits the target message to be sent to the message transmission channel, the second When the second vehicle-mounted terminal detects that the message to be sent by the target is a message that needs to be received, the second vehicle-mounted terminal will receive and respond, so that the vehicle is in a corresponding control state.

Exemplarily, after the user steps on the accelerator to control the acceleration of the vehicle, the vehicle controller (first vehicle terminal) will generate a message of the type of acceleration to be sent, and transmit the message of the type of acceleration to be sent to the message transmission channel , so that the vehicle power subsystem receives the message of the acceleration type, and then, the vehicle power subsystem responds to the information data in the message of the acceleration type, so that the vehicle is in the accelerated state, such as when the vehicle accelerates to 60 hours per hour , keep sailing at this speed.

208. The second vehicle terminal generates a target feedback message according to the response result, and transmits it to the message transmission channel.

Specifically, after the second vehicle-mounted terminal completes the response, it will generate a target feedback message according to the response and upload it to the message transmission channel to feed back the response to the "target message to be sent" to the first vehicle-mounted terminal.

Exemplarily, after the vehicle power subsystem receives the acceleration type message from the message transmission channel, it can respond to the information data in the acceleration type message, and return a response information data according to the response situation, specifically Feedback is performed in the form of a target feedback message to inform the first vehicle-mounted terminal of the response to the acceleration event, such as the amount of acceleration and the current speed per hour.

209. The first vehicle-mounted terminal determines the identification range value of the receivable message, and reads the target feedback message conforming to the identification range value from the message transmission channel.

Wherein, the identifier range value may be a message identifier range value, which is used to limit the data packets that can be received by the local end, so as to selectively receive feedback packets, so as to avoid the load of irrelevant data packets on the vehicle system.

Exemplarily, with the vehicle controller as the first vehicle-mounted terminal, the message identification range that the vehicle controller can use can be "0x100" to "0x320", when the transmission identification in the message transmission channel is "0x110" If the message matches the identification range value of the vehicle controller, the vehicle controller can receive the "0x110" message, that is, the target feedback message.

210. The first vehicle-mounted terminal identifies an execution state of the message response function, and executes a message response policy corresponding to the target feedback message when the execution state is an idle state.

Specifically, after receiving the target feedback message for the sent message, the first vehicle-mounted terminal can obtain the message response strategy corresponding to the target feedback message, and execute the message response strategy to make a response in the vehicle system. Responses, such as alerting the driver.

Among them, when the first vehicle-mounted terminal receives multiple target feedback messages at the same time in the process of responding to the message, in order to avoid confusion when the target feedback message responds, the message response function can be used to control the response of each target. The response process of the feedback message. Wherein, the message response function may be a function for managing the message response process, which may be understood as a response interrupt function, which is used to limit the transmission of the target response message during the message response process.

Specifically, the execution state of the message response function is identified, and when the execution state is idle, the target feedback message is sent to the message responder, so that the message responder executes the message response policy corresponding to the target feedback message. Exemplarily, taking the voice announcer as the message response terminal as an example, if the target feedback message is an acceleration type feedback message, the information prompt strategy of the acceleration type can be queried, and the acceleration result of the vehicle can be checked according to the information prompt policy. Tips, such as broadcasting the vehicle speed, speed increase, safety factor of the current speed, etc. through voice.

It should be noted that part of the descriptions about the embodiments of the present application are the same as the descriptions of the foregoing embodiments, for details, reference may be made to the foregoing embodiments, and details are not repeated here.

For ease of understanding, steps 201-210 are executed, with reference to FIGS. 5-7 , taking any two controllers in the vehicle system as an example, an example scenario of vehicle data transmission is described. details as follows:

1. Architecture of the vehicle data transmission system

The vehicle data transmission system is formed by connecting multiple controllers and message transmission channels. Specifically, the message transmission channel may be a CAN bus (Controller Area Network, CAN) in the vehicle system, that is, a CAN Bus or a CAN bus. The CAN bus communicates with various control units (systems) in the vehicle system, for example, the CAN bus is connected with the vehicle power subsystem, the vehicle lighting system, the vehicle window system, the air conditioning system, and the like.

Exemplarily, as shown in FIG. 5 , the architecture of the vehicle data transmission system includes a first controller (which may correspond to the first vehicle-mounted terminal) and a second controller (which may correspond to the second vehicle-mounted terminal), the first controller and the second vehicle-mounted terminal The two controllers are respectively connected to CANBus, and the vehicle information data can be exchanged between the two through CAN Bus. Wherein, the first controller and the second controller may be identical or similar in structure.

For ease of understanding, the first controller is used as an example for description. In addition to the capabilities of information data generation, message generation, and message response management, the first controller may also include a CAN controller, a message sending storage unit, and a message receiving storage unit. Wherein, a message buffer space (that is, a message buffer array) may be constructed in the CAN controller for receiving the messages to be sent generated by the first controller and sorting the messages to be sent. Wherein, the message sending storage unit can be used to upload the message to be sent to the CAN Bus. Among them, the message receiving storage unit is used to receive any message that needs to be processed from the CAN Bus, such as the target feedback message uploaded by the second controller to the CAN Bus, in addition, it can also receive any other message that needs to be processed, It can even receive the "message to be sent" sent from the local end, so that the CAN controller in the first controller can understand the transmission situation of the message.

2. Example of the vehicle data transmission scenario

Specifically, in combination with the message arbitration feature of the CAN bus, a message buffer space, that is, a cache array, is constructed in the CAN controller through a software sending and receiving buffer mechanism to expand the total number of messages that can be sent and received by the first controller and the second controller . In order to facilitate understanding, the first controller will be taken as an example, and the sending and receiving scenarios of the data message in the vehicle system will be described in combination with FIG. 6 and FIG. 7, as follows:

(1) It should be noted that due to the arbitration characteristics of the CAN bus, for CAN messages to be sent, even if relatively low-priority messages have been transmitted to the message sending storage unit, it is necessary to wait for higher priority on the CAN bus. After sending the message of the first level, the message of the relatively low priority can obtain the control right to the CAN bus. In this regard, the messages to be sent can be sorted according to the message priority relationship, so that the messages with high priority are put into the message sending storage unit first, and so on. Specifically as shown in Figure 6, the message sending process is:

(1.1) Configure the message sending storage unit in the first controller as the sending direction.

(1.2) According to the software sending and receiving cache mechanism, a message buffer space is created in the CAN controller, that is, a message buffer array. The size of the message volume contained in the array must be greater than the total number of messages to be sent.

(1.3) Send messages into the cache array, sort according to the order of message arbitration priority from high to low, so that subsequent high-priority messages enter the message sending storage unit first; it should be noted that due to the Control messages involve processing timeliness. Therefore, the corresponding message identifiers are generally relatively small, and the message priority is relatively high, so as to obtain the right to use the CAN bus first.

(1.4) During the transmission of the message, before the message sending storage unit sends the message to the CAN bus, it will trigger the interrupt transmission service, and after the message sending storage unit sends the message to the CAN bus, The sending completion interrupt function is triggered, so that the unsent messages in the sending message buffer array are transferred to the message sending storage unit in the sending completion interrupt service function.

(2) The first controller is receiving CAN messages. Taking the message receiving storage unit as an example containing a single CAN channel, the standard frame of a complete frame of CAN messages usually occupies 111 bits, and the rate is usually set to 500kbps (kilobit rate, referring to is the transmission rate of the digital signal), and the time of one frame is about 222us. Therefore, when the first controller receives a frame of CAN message, it takes out the message from the CAN controller within 222us, so as to ensure that the CAN message will not be lost. Specifically as shown in Figure 7, the message receiving process is:

(2.1) Set hardware CANID filtering to filter unnecessary received messages according to the message identification range value. The filtered message (such as the target feedback message) is received by the message receiving and storing unit, thereby reducing the frequency of subsequent interrupt responses and at the same time reducing the load of the first controller.

(2.2) Determine the CAN message identifiers (ie IDs) to be received, and sort them in ascending order to generate a corresponding filter array. It should be noted that the sorting process can be pre-processed, for example, the array can be sorted and generated before receiving the message, so as to reduce the time spent on message query matching.

(2.3) For the message received in the message receiving storage unit, query and match it with the filter array in a dichotomous manner, if matched, then take out the message, end the interrupt processing function, and respond.

By executing the above scenario examples, the following scenarios can be realized:

Exemplarily, the vehicle system contains multiple controllers (units), each controller corresponds to a control subsystem, the vehicle controller is used as the first controller, and the controller of the vehicle power subsystem is used as the second control device. Specifically, after the user steps on the accelerator to control the acceleration of the vehicle, the vehicle controller will generate a message to be sent of the acceleration type and transmit the message to the CAN Bus; furthermore, the control of the vehicle power subsystem The device receives the message of the acceleration type from the CAN Bus, and responds to the information data in the message of the acceleration type. After completing the response, it can return a response information data according to the response situation, such as through the target feedback message Feedback the corresponding response in the form of feedback to inform the vehicle controller of the response to the acceleration event; finally, the vehicle controller can receive the target feedback message from the CAN Bus and respond to the target feedback message to Send prompt information to the user, such as broadcasting the vehicle speed per hour, speed increase, safety factor of the current speed, etc. through voice.

From the above scenario examples, it can be obtained that through software optimization and ingeniously combining the characteristics of the CAN bus, on the premise of ensuring that CAN messages are not lost, the problem of insufficient space in the message receiving/sending storage unit can be effectively solved. The hardware configuration of the vehicle (such as the vehicle chip) reduces costs and increases efficiency.

It can be seen from the above that the embodiment of the present application can first determine the message of the vehicle data to be transmitted, and sort the priority of the message to be sent in the message buffer space, and then, according to the order of the priority sequence of the message The relationship is to transmit the message to be sent, effectively avoiding that the message with lower priority occupies the space of the sending and receiving storage unit during message transmission, and finally, receive the target feedback message corresponding to the message to be sent, and execute the corresponding target feedback message In this way, the total amount of vehicle data transmission can be expanded to a certain extent to meet the transmission requirements of vehicle data, improve the response efficiency of vehicle business functions, and improve user experience.

In order to better implement the above method, an embodiment of the present application further provides a vehicle data transmission device, which can be integrated into computer equipment, such as computer equipment such as a vehicle-mounted terminal.

In some embodiments, the sending unit 803 is also used to: identify the function state corresponding to the message sending function; when the function state is a sendable state, select the target to be sent according to the message priority relationship in the message priority sequence Message: Based on the message sending function, the target message to be sent is sent to the message transmission channel.

In some implementations, the detection unit 804 is further configured to: determine the identification range value of the receivable message; pull the message to be confirmed that meets the value of the identification range from the message transmission channel; determine the message to be confirmed as the pending message Send the target feedback message corresponding to the message.

In some embodiments, the detection unit 804 is further configured to: identify the identifier of the message to be confirmed corresponding to the message to be confirmed; obtain an array of message identifiers, and match the identifier of the message to be confirmed with the identifiers in the array of message identifiers, Obtain a matching result; determine the message type of the message to be confirmed according to the matching result, and determine the message to be confirmed as a target feedback message corresponding to the message to be sent of the message type.

In some embodiments, the vehicle data transmission device further includes a construction unit, configured to: query the target message identifiers of multiple receivable messages; sort the multiple target message identifiers according to the size relationship of the identifiers to obtain the message identifier sequence ; Generate an array of message IDs according to the sequence of message IDs.

In some implementations, the execution unit 805 is also used to: identify the execution state of the message response function; when the execution state is idle, send the target feedback message to the message response end, so that the message response end executes the target The message response strategy corresponding to the feedback message; when the execution state is not idle, the message response progress of the message response end is detected; when the message response progress reaches the preset progress threshold, the target feedback message is sent to the message The responder enables the message responder to execute the message response policy corresponding to the target feedback message.

It can be seen from the above that the embodiment of the present application can first determine the message of the vehicle data to be transmitted, and sort the priority of the message to be sent in the message buffer space, and then, according to the sequence relationship of the priority sequence of the message The message to be sent is transmitted to effectively prevent the message with lower priority from occupying the space of the sending and receiving storage unit during message transmission. Finally, the target feedback message corresponding to the message to be sent is received, and the corresponding target feedback message is executed. Message response strategy; in this way, the total amount of vehicle data transmission can be expanded to a certain extent to meet the transmission requirements of vehicle data, improve the response efficiency of vehicle business functions, and improve user experience.
