Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The following describes a vehicle anti-collision control method, a device, a system and a vehicle provided by the embodiment of the invention with reference to fig. 1 to 7.
Fig. 1 shows a vehicle anti-collision control method provided by an embodiment of the present invention, where the method includes:
Step 101, acquiring running state information and road condition information of a first vehicle;
Step 102, if the first vehicle is judged to be in an abnormal state based on the driving state information, and a second vehicle approaching to the first vehicle exists in the driving direction of the first vehicle based on the road condition information, the first vehicle is controlled to send out first prompt information.
In this embodiment, the running state information of the first vehicle may include a current vehicle speed and a current running state of the first vehicle, by which it may be determined whether the first vehicle is running at a slower speed or is parked at a roadside, by which it may be determined whether the first vehicle is in a flameout state, and in an actual application process, it may be determined whether the first vehicle is in a flameout state by determining whether a vehicle key is in an OFF state.
In the practical application process, the road condition information of the first vehicle can be obtained through a data acquisition device installed on the first vehicle, for example, the road condition information can be obtained through video data acquired by a video acquisition device, whether an incoming vehicle exists in the running direction of the first vehicle can be determined through the video data, and whether the second vehicle approaches to the first vehicle is determined according to the relative speed of the incoming second vehicle and the first vehicle.
In an exemplary embodiment, determining that the first vehicle is in an abnormal state based on the driving state information may include:
If the current vehicle speed in the running state information is below the preset vehicle speed and the current running state in the running state information is in a non-flameout state, judging that the first vehicle is in an abnormal state.
If the first vehicle is in the abnormal state, and if the second vehicle approaches to the first vehicle in the running direction of the first vehicle, the second vehicle does not know the running state of the first vehicle in time, so that a collision accident can be caused. Particularly, when the second vehicle is driven from the rear of the first vehicle, a rear-end collision accident is extremely easy to occur.
Therefore, when the first vehicle is determined to be in an abnormal state and the second vehicle approaching the first vehicle in the driving direction of the first vehicle is determined, the first vehicle can be controlled to send out the first prompt information, so that the second vehicle is timely reminded, and the occurrence probability of collision accidents is reduced.
In the actual application process, the dangerous alarm lamp of the first vehicle can be controlled to be turned on so as to send out first prompt information.
Referring to fig. 2, taking the second vehicle as another vehicle traveling behind and close to the first vehicle, the first prompt message is taken as an example by turning on a hazard warning lamp of the first vehicle, so as to describe the implementation flow of the step 102 in detail, which may specifically include:
step 201, judging whether the first vehicle key is in an OFF position or not so as to determine whether the first vehicle is in a flameout state or not;
Step 202, if the first vehicle is in a non-flameout state, further judging whether the current speed of the first vehicle is below a preset speed, wherein the preset speed can be 5km/h in the embodiment;
step 203, if the current speed of the first vehicle is below the preset speed, further judging whether a second vehicle approaches behind the first vehicle;
And 204, if the second vehicle approaches behind the first vehicle, controlling the first vehicle to turn on the hazard warning lamp so as to send out the first prompt message, and ending the flow.
In an exemplary embodiment, after acquiring the driving state information of the first vehicle and the road condition information, the method may further include:
acquiring an early warning setting state of a first vehicle;
If the early warning setting state is a non-manual state and the second vehicle is judged to have collision risk based on the road condition information, the first vehicle is controlled to send out second prompt information.
In the actual application process, in order to ensure the reliability of the anti-collision control process, the embodiment first determines the early warning setting state of the first vehicle, determines whether the current early warning setting state is a manual state or an automatic state, if the current early warning setting state is the manual state, does not perform collision risk determination, and if the current early warning setting state is the non-manual state, performs collision risk determination.
In the actual application process, the relative speed of the second vehicle and the first vehicle can be compared and analyzed with the preset relative speed, when the relative speed of the second vehicle and the first vehicle is higher than the preset relative speed threshold, the collision risk is judged to exist, of course, the judgment of the collision risk can be realized in other modes according to the actual application requirement, for example, whether the collision risk exists can be judged according to the relative distance between the second vehicle and the first vehicle, and the collision risk can be reasonably set according to the actual application scene requirement, and the excessive description is omitted.
In this embodiment, the second prompt information may be a light prompt information and/or a voice prompt information, for example, an early warning prompt lamp or a voice alarm may be set on the first vehicle, and the early warning prompt lamp may send out an early warning prompt light, and the voice alarm may also send out an early warning prompt sound, so as to achieve the purpose of timely and striking prompting that the driver of the second vehicle has a collision risk.
In an exemplary embodiment, the vehicle anti-collision control method may further include:
Receiving an early warning setting instruction;
responding to the early warning setting instruction, and setting an early warning mode corresponding to the second prompt information.
Because the second prompt information can early warn through the light prompt mode and the voice prompt mode, the pedestrian can be influenced when the second vehicle is reminded by considering the voice prompt mode, the early warning mode can be set, particularly, a central control screen on the first vehicle or a mobile terminal is provided with a soft switch such as a voice alarm mode setting switch and the like, an early warning setting instruction can be sent through the central control screen or the mobile terminal (such as a mobile phone APP), a driver of the first vehicle can set to start voice alarm or close voice alarm, the early warning mode corresponding to the second prompt information is further adaptively set according to the early warning setting instruction, when the voice alarm is closed, the second prompt information can be sent only through the light prompt mode, and when the voice alarm is started, the second prompt information can be sent through the light prompt mode and the voice prompt mode.
In order to achieve a better prompting effect, in the practical application process, the brake lamp on the first vehicle and the early warning prompting lamp can be matched and synchronously used for lamplight prompting.
Fig. 3 shows a setup flow of the early warning mode, which may specifically include:
step 301, an early warning setting instruction is sent out, for example, whether a voice alarm is started or not can be set through a central control screen of a first vehicle or a touch key on a mobile phone APP so as to send out the early warning setting instruction;
Step 302, receiving an early warning setting instruction, for example, receiving the early warning setting instruction through a T-BOX terminal on a first vehicle;
and 303, responding to the early warning setting instruction, and setting an early warning mode corresponding to the second prompt information, thereby finishing the setting of the alarm mode.
In an exemplary embodiment, after acquiring the early warning setting state of the first vehicle, it may further include:
If the early warning setting state is a non-manual state and the second vehicle is judged to have collision risk based on the road condition information, the road condition information of the first vehicle is stored and reported.
According to the method and the system for reporting the road condition information of the first vehicle, when the collision risk is found to exist in the non-manual state, the road condition information of the first vehicle can be stored and reported, for example, the road condition information of the first vehicle can be reported to a vehicle networking platform, a user can check and download related videos and current vehicle speed information on a mobile phone APP or a vehicle-mounted central control screen in time, and basis can be provided for accident responsibility judgment in time, so that the follow-up collision accident can be relied upon.
In an exemplary embodiment, after acquiring the early warning setting state of the first vehicle, it may further include:
if the early warning setting state is a non-manual state and the collision risk of the second vehicle is judged based on the road condition information, communication connection is established with the second vehicle;
sending an early warning control signal to a second vehicle;
the second vehicle is used for sending out third prompt information according to the early warning control signal.
When detecting that there is a collision risk, if the first vehicle and the second vehicle are vehicles of the same manufacturer or the vehicles are running on an intelligent highway, that is, when allowing vehicles of different manufacturers to run on a highway with an open V2V (Vehicle to Vehicle, vehicle-to-vehicle) function, the communication connection between the first vehicle and the second vehicle can be realized through a V2V technology, and then corresponding voice and light alarm in a cab of the second vehicle is controlled so as to send out third prompt information.
Fig. 4 illustrates a specific control flow of the second prompt message and the third prompt message sending process, taking a rear-end collision prevention scenario as an example, and specifically includes:
step 401, firstly judging whether the early warning setting state is a manual state;
Step 402, if the judgment result in step 401 is no, monitoring the rear situation in real time through the road condition information of the first vehicle, for example, continuously monitoring the rear situation of the first vehicle through a high-definition camera installed on the first vehicle;
step 403, judging whether rear-end collision risk exists or not according to the road condition information of the first vehicle;
step 404, if the judgment result in step 403 is no, that is, no collision risk exists, sending out a stop alarm signal, and controlling the early warning indicator lamp and the loudspeaker to be closed so as to stop lamplight and voice alarm;
Step 405, sending a stop alarm signal to the first vehicle, and specifically, transmitting the stop alarm signal to a T-BOX terminal of the first vehicle;
Step 406, controlling the first vehicle to stop the vehicle light alarm, specifically, forwarding a stop alarm signal to a vehicle body controller by the T-BOX terminal so as to stop the vehicle light alarm;
Step 407, storing and reporting road condition information of the first vehicle when the judging result of the step 403 is yes or the judging result of the step 401 is yes, namely, when rear-end collision risk exists or the early warning setting state is a manual state, specifically, video data shot by a high-definition camera can be stored locally and can be reported to a vehicle networking platform;
Step 408, alarming in a light prompting mode, for example, an LED module arranged on the first vehicle can be turned on to alarm in a light prompting mode;
step 409, further judging whether to turn on the voice alarm according to the early warning setting instruction;
Step 410, if the judgment result in step 409 is yes, namely, the voice alarm is set to be started, the voice alarm is started, and the synchronous alarm is carried out in a light prompting mode and a voice prompting mode so as to send out second prompting information;
Step 411, if the determination result in step 409 is no, that is, the voice alarm is not set to be turned on, the voice alarm is turned off, and only the alarm is given by a lamplight prompt mode so as to send out second prompt information;
step 412, sending the road condition information and the alarm signal to the first vehicle, and specifically transmitting the video information and the alarm signal to a T-BOX terminal of the first vehicle;
Step 413, controlling the first vehicle to perform vehicle light alarm, specifically, forwarding a signal to a vehicle body controller through a T-BOX terminal to control the vehicle light alarm, for example, starting a brake lamp to perform alarm, and uploading video information to a vehicle networking platform and a central control screen;
Step 414, the pre-tightening control signal is sent to the second vehicle through the T-BOX terminal of the second vehicle, and then the second vehicle is controlled to send third prompt information, such as a voice prompt through the central control screen of the second vehicle.
Therefore, when the vehicle runs at a lower speed or the vehicle stops at the roadside due to faults, if a driver forgets to turn on the dangerous alarm lamp, the dangerous alarm lamp is automatically turned on when the first vehicle detects that the vehicle runs in the driving direction, road condition information such as video pictures and speed information perceived by a camera can be stored locally when the vehicle is detected to have a rear-end collision risk, the road condition information can be uploaded to a vehicle networking platform through a T-BOX terminal of the first vehicle for cloud storage, when a collision accident occurs, such as rear-end collision, a user can timely check and download related videos and speed information on a mobile phone APP and a vehicle-mounted central control screen, basis can be provided for accident responsibility judgment in time, in addition, when the first vehicle detects that the first vehicle has a rear-end collision risk, the first vehicle can control a central control screen in a driving cab to carry out voice alarm, so that the driver of the second vehicle can reduce the speed in time better, the occurrence of the collision accident is avoided to a great extent, and the safety and reliability of the vehicle collision control process are improved.
