A CAN transceiver-compatible communication method, device, electronic device, and medium provided in the embodiments of the present application will be described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.

Referring to Fig. 1, Fig. 1 is one of the flowchart diagrams of a communication method compatible with CAN transceivers provided in the embodiment of the present application. As shown in Fig. 1, the method is applied to a vehicle network bus management system, and the vehicle network bus The management system includes N control chips and CAN transceivers corresponding to the N control chips one by one, specifically including the following steps:

Step 101. Read a first parameter of a target control chip, wherein the target control chip is any one of the N control chips.

It is worth mentioning that the control chip in this application can be an electronic control unit ECU, or other control structures capable of performing control logic processing and sending application messages to the CAN bus. The above-mentioned target control chip can be one of the control chips in the vehicle network management bus, and the target control chip is correspondingly connected with a CAN transceiver, that is, the target CAN transceiver. The CAN transceiver can be used as the interface between the control chip and the physical bus, convert the logic level of the control chip into the differential level of the CAN bus, and transmit data on two bus cables with differential voltages.

In the above steps, by reading the first parameter of the target control chip, the communication rule or command of the target control chip can be determined, and based on the first parameter, it is transmitted to the CAN transceiver that can receive the matching rule of this type, so that the target control The chip corresponds to the target CAN transceiver. In this way, when the demand for the target control chip is received, the target control chip can be woken up through the target CAN transceiver to form a high-speed, synchronous transmission channel.

Step 102, obtain preset M read-write register drivers, respectively obtain the second parameters of the target CAN transceiver based on each of the read-write register drivers, and obtain M second parameters, wherein the target The CAN transceiver is the CAN transceiver corresponding to the target control chip, one read-write register driver corresponds to a CAN transceiver, and M is an integer greater than 1.

It is worth noting that the embodiment of this application is aimed at the application of different types of CAN transceivers. It is difficult for the control chip to communicate with the CAN transceiver, and it is necessary to reconfigure the register read and write driver corresponding to this type of CAN transceiver. . Preset read and write register drivers of various models for the target CAN transceiver, and implement a software version that is compatible with multiple types of CAN transceivers. Please refer to Figure 2, for example, the relationship between existing CAN transceivers and control chips is that 3 types of CAN transceivers require 3 hardware settings and 3 software settings, and this application pre-sets TCAN, TJA, UJC Wait for the read-write register driver program of each type of CAN transceiver, write TJA_1146_ReadReg(), and prepare the call of the read-write register by the target CAN transceiver at any time. Finally, the 3 types of CAN transceivers only need 1 hardware setting and 1 software settings.

In addition, since each read-write register driver corresponds to a type of CAN transceiver, it is necessary to determine the register driver of the target CAN transceiver corresponding to the target control chip, which can be determined by determining the first register driver corresponding to each register driver. Two parameters, through the second parameter to identify the read and write register driver required by the specific CAN transceiver to communicate with the control chip. In this way, the preset read and write register drivers corresponding to various types of CAN transceivers can be compatible with various types of CAN transceivers. After replacing different CAN transceivers, there is no need to configure drivers for this type, which can reduce development and maintenance. cost and improve system efficiency.

Step 103: Compare the first parameter and the M second parameters, and obtain a target second parameter matching the first parameter, and the M second parameters include the target second parameter.

In this step, based on the obtained first parameter of the target control chip and the second parameter corresponding to each register driver, the first parameter and the second parameter are compared and matched. The comparison and matching between the first parameter and the second parameter may specifically be that the rule setting corresponding to the first parameter is consistent with the rule setting corresponding to the second parameter, or that the instruction setting of the first parameter is consistent with the instruction setting of the second parameter. be consistent.

Step 104: Determine that the read-write register driver corresponding to the target second parameter is the target read-write register driver, wherein the target read-write register driver is used to drive the target control chip and the Data transfer between target CAN transceivers.

In a specific implementation, the target second parameter can represent the specific applicable rules of the read-write register driver in a type of CAN transceiver, and when the first parameter matches the target second parameter, the target second parameter can be determined The corresponding read-write register driver can drive and wake up the target control chip. When communication is required, it can transmit the communication signal to the target control chip, and can also receive the communication signal sent by the target control chip to the CAN bus. In this way, the second parameter of the target corresponds to The read-write register driver as the target read-write register driver can drive the data transmission between the target control chip and the target CAN transceiver. Even if different types of CAN transceivers are replaced, a communication channel can be established between the target control chip and the target CAN transceiver through the specific method of the embodiment of the present application, and the target read-write register driver in the replaced CAN transceiver can be determined Therefore, the present application can be compatible with different types of CAN transceivers, and the communication connection to the control chip can be realized through the CAN transceivers.

Optionally, before reading the first parameter of the target control chip, it also includes:

Carry out system initialization operation to described vehicle-mounted network bus management system;

Connect the preset pins on the target control chip to the corresponding target CAN transceiver through the serial peripheral interface SPI configuration, and set the third parameter of the SPI, wherein the third parameter includes wave special rate.

In the specific implementation, first, the vehicle network bus management system is initialized to facilitate the configuration and identification between the subsequent control chip and its corresponding CAN transceiver, reduce the interference of other operations, and improve the efficiency of identification and communication. In addition, configuring one-to-one correspondence between the target control chip and the target CAN transceiver includes two aspects: On the one hand, in terms of hardware settings, each control chip can use consistent pins to connect to the Serial Peripheral Interface (SPI) , occupy four consistent wires on the pins of each control chip. In this way, the control chip adopts SPI configuration, which can save pins, save space for a printed circuit board (PCB) where it is located, and can also provide a high-speed, synchronous communication channel. On the other hand, in terms of software settings, by configuring the parameters of the SPI between the control chip and its corresponding CAN transceiver, the communication channel between the control chip and the CAN transceiver can transmit communication signals quickly and synchronously, for example, configure The baud rate of SPI can pre-set the rate of symbol transmission between the control chip and its corresponding CAN transceiver, which facilitates identification between the subsequent target control chip and its corresponding target CAN transceiver, and wakes up in time after identification.

Optionally, the reading the first parameter of the target control chip includes:

calling the preset registers in the target control chip;

reading a first parameter of the target control chip based on the preset register;

Wherein, the first parameter includes an electrical parameter, a physical parameter, a model of the preset register and a first address of the target control chip.

It should be noted that the acquisition of the first parameter of the above-mentioned target control chip can be based on the built-in preset register of the target control chip, and the first parameter related to the target control chip can be obtained by calling the preset register, and the first parameter can be It is the parameter information included in the specification sheet (Datasheet) of the control chip, specifically, it may be the pin configuration, electrical parameters, physical parameters, etc. of the control chip. Since the factory configuration of different control chips is different, the datasheet content is different, and the specific characteristic specifications are also different, so it is necessary to apply the CAN transceiver corresponding to the control chip. Therefore, the CAN transceiver needs to call the read-write register driver that can match the control chip, so as to realize the communication between the control chip and the CAN transceiver.

Optionally, after determining that the read-write register driver corresponding to the target second parameter is the target read-write register driver, the method further includes:

In the case of network wake-up occurring in the vehicle-mounted network bus management system, obtain a fourth parameter of the control chip to be woken up, wherein the fourth parameter includes a second address of the control chip to be woken up;

comparing the target second parameter determined based on the target read-write register driver program with the fourth parameter;

If the first address included in the target second parameter is consistent with the second address included in the fourth parameter, wake up the target control chip corresponding to the second address.

It is worth mentioning that the network wake-up management in this application is set out of the consideration of power saving for new energy vehicles, because all electronic control units on new energy vehicles will communicate with each other through CAN bus, Ethernet, etc. Communication, and network management is to realize the cooperative sleep or wake-up of each ECU by setting fixed rules or commands on the network of each ECU. Sleeping when there is no need for communication, and waking up when communication is required, is convenient for saving battery power of new energy vehicles. In addition, when the vehicle needs the ECU, the CAN transceiver can be woken up at any time, receive the message of the vehicle, and send the application message of the ECU.

In a specific implementation, after the target control chip and the target CAN transceiver establish a communication connection, when the entire vehicle needs to wake up the target control chip, the fourth parameter of the target control chip can be transferred, and the fourth parameter can specifically be the The second address of the target control chip. Subsequently, the fourth parameter can be given to the CAN bus, and the CAN bus sends the second address to each CAN transceiver, and each CAN transceiver identifies whether the second address is second to the target address of the internal target read-write register driver. Parameters are associated, if the target second parameter determined by the target read-write register driver program matches the comparison result between the fourth parameter, at this time, it can be determined that the target control chip that needs to be woken up is the target read-write register driver. The control chip corresponding to the register driver directly wakes up the target control chip through the target CAN transceiver, thus completing the wake-up of the target control chip. Therefore, by setting the target read-write register driver, the application can realize the compatible connection and configuration control chip between different types of CAN transceivers, which facilitates production control and reduces development and maintenance costs.
