[0043] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0044] The following combination Figures 1 to 7 The vehicle anti-collision control method, device, system and vehicle provided by the embodiments of the present invention are described.

[0045] Figure 1 The vehicle anti-collision control method provided by an embodiment of the present invention is shown, and the method includes:

[0046] Step 101: Acquire driving status information and road condition information of a first vehicle;

[0047] Step 102: If it is determined based on the driving state information that the first vehicle is in an abnormal state, and it is determined based on the road condition information that there is a second vehicle approaching the first vehicle in the driving direction of the first vehicle, the first vehicle is controlled to issue a first prompt message.

[0048] In this embodiment, the driving status information of the first vehicle may include the current speed and current operating status of the first vehicle. The current speed can be used to determine whether the first vehicle is driving at a slower speed or parked on the roadside. The current operating status can be used to determine whether the first vehicle is in an ignition-off state. In actual application, whether the first vehicle is in an ignition-off state can be determined by determining whether the vehicle key is in an OFF state.

[0049] In actual application, the road condition information of the first vehicle can be obtained through a data acquisition device installed on the first vehicle, such as video data collected by a video acquisition device. The video data can be used to determine whether there are oncoming vehicles in the direction of travel of the first vehicle, and based on the relative speed of the oncoming second vehicle and the first vehicle, it can be determined whether the second vehicle is approaching the first vehicle.

[0050] In an exemplary embodiment, determining that the first vehicle is in an abnormal state based on the driving state information may specifically include:

[0051] If the current vehicle speed in the driving state information is lower than the preset vehicle speed and the current running state in the driving state information is in a non-ignition-off state, it is determined that the first vehicle is in an abnormal state.

[0052] If the first vehicle is in the above abnormal state, and a second vehicle approaches it in its direction of travel, a collision may occur because the second vehicle fails to promptly detect the first vehicle's travel status. This is especially true if the second vehicle approaches from behind the first vehicle, which can easily lead to a rear-end collision.

[0053] To this end, when this embodiment determines that the first vehicle is in an abnormal state and a second vehicle appears to be approaching it in its driving direction, it can control the first vehicle to issue a first prompt message, thereby promptly reminding the second vehicle to reduce the probability of a collision accident.

[0054] In actual application, the first prompt information can be issued by controlling the hazard warning lights of the first vehicle to turn on.

[0055] See attached Figure 2 Taking the second vehicle as another vehicle traveling behind and close to the first vehicle, and the first prompt information being by turning on the hazard warning lights of the first vehicle as an example, the implementation process of the above step 102 is described in detail, which may specifically include:

[0056] Step 201: Determine whether the first vehicle key is in the OFF position to determine whether the first vehicle is in the ignition off state;

[0057] Step 202: If the first vehicle is in a non-stop state, further determining whether the current speed of the first vehicle is below a preset speed. In this embodiment, the preset speed may be 5 km / h.

[0058] Step 203: If the current speed of the first vehicle is below the preset speed, further determining whether a second vehicle is approaching from behind the first vehicle;

[0059] Step 204: If a second vehicle approaches behind the first vehicle, the first vehicle is controlled to turn on the hazard warning lights to issue a first prompt message, and the process ends.

[0060] In an exemplary embodiment, after obtaining the driving state information and road condition information of the first vehicle, the following steps may also be included:

[0061] Obtaining the warning setting status of the first vehicle;

[0062] If the warning setting state is non-manual, and it is determined based on the road condition information that the second vehicle has a collision risk, the first vehicle is controlled to issue a second prompt message.

[0063] In actual application, in order to ensure the reliability of the anti-collision control process, this embodiment first determines the warning setting status of the first vehicle, and judges whether the current warning setting status is manual or automatic. If it is manual, no collision risk judgment is performed. If it is non-manual, a collision risk judgment is performed.

[0064] In actual application, the relative speed of the second vehicle and the first vehicle can be compared 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, it is determined that there is a collision risk. Of course, other methods can also be used to determine the collision risk according to actual application requirements. For example, whether there is a collision risk can be determined based on the relative distance between the second vehicle and the first vehicle. The specific settings can be reasonable according to the actual application scenario, and no further details will be given here.

[0065] In this embodiment, the second prompt information can be a light prompt information and / or a voice prompt information. For example, a warning prompt light or a voice alarm can be set on the first vehicle. A warning prompt light can be emitted by the warning prompt light, or a warning prompt sound can be emitted by the voice alarm, so as to achieve the purpose of timely and eye-catchingly reminding the driver of the second vehicle that there is a collision risk.

[0066] In an exemplary embodiment, the vehicle anti-collision control method may further include:

[0067] Receive warning setting instructions;

[0068] In response to the warning setting instruction, the warning mode corresponding to the second prompt information is set.

[0069] Since the second prompt information in this embodiment can be warned by light prompting and voice prompting, considering that the voice prompting may affect pedestrians while reminding the second vehicle, this embodiment can set the warning mode. Specifically, the central control screen on the first vehicle or the mobile terminal has a soft switch such as a voice alarm mode setting switch. A warning setting instruction can be issued through the central control screen or the mobile terminal (such as a mobile phone APP). The driver of the first vehicle can set the voice alarm to be turned on or off, and then adapt the warning mode corresponding to the second prompt information according to the warning setting instruction. When the voice alarm is turned off, the second prompt information can be issued only by light prompting. When the voice alarm is turned on, the second prompt information can be issued by both light prompting and voice prompting.

[0070] In order to achieve a better prompting effect, in actual application, the brake lights on the first vehicle can be used in conjunction with the above-mentioned warning lights to provide light prompts synchronously.

[0071] Figure 3 The following figure shows the process of setting the warning mode, which may include:

[0072] Step 301: issuing an early warning setting instruction, for example, by setting whether to enable a voice alarm through the central control screen of the first vehicle or a touch button on a mobile phone APP to issue an early warning setting instruction;

[0073] Step 302: Receive an early warning setting instruction, for example, by receiving the early warning setting instruction via a T-BOX terminal on the first vehicle;

[0074] Step 303: In response to the warning setting instruction, the warning mode corresponding to the second prompt information is set, thereby completing the alarm mode setting.

[0075] In an exemplary embodiment, after obtaining the warning setting status of the first vehicle, the method may further include:

[0076] If the warning setting state is non-manual, and it is determined based on the road condition information that the second vehicle has a collision risk, the road condition information of the first vehicle is stored and reported.

[0077] When the risk of collision is detected in the non-manual state, this embodiment can store and report the road condition information of the first vehicle. For example, the road condition information of the first vehicle can be reported to the Internet of Vehicles platform. The user can view and download relevant videos and the vehicle speed information at that time on the mobile phone APP or the vehicle's central control screen in time, and can provide a basis for accident judgment in time, so that there is a basis for reference in the event of a subsequent collision accident.

[0078] In an exemplary embodiment, after obtaining the warning setting status of the first vehicle, the method may further include:

[0079] If the warning setting state is non-manual, and it is determined based on the road condition information that the second vehicle has a collision risk, a communication connection is established with the second vehicle;

[0080] sending a warning control signal to the second vehicle;

[0081] Among them, the second vehicle is used to issue a third prompt information according to the early warning control signal.

[0082] When a collision risk is detected, if the first vehicle and the second vehicle are vehicles of the same manufacturer or the vehicles are traveling on a smart highway, that is, when traveling on a highway that allows V2V (Vehicle to Vehicle) functions between vehicles of different manufacturers, the first vehicle and the second vehicle can be connected in communication through V2V technology, thereby controlling the corresponding voice and light alarms in the cab of the second vehicle to issue a third prompt message.

[0083] Figure 4 Taking the rear-end collision prevention scenario as an example, the specific control flow of the second prompt information and the third prompt information issuance process is shown, which specifically includes:

[0084] Step 401: First, determine whether the warning setting state is manual;

[0085] Step 402: If the result of the determination in step 401 is negative, the rear situation is monitored in real time using the road condition information of the first vehicle. For example, a high-definition camera installed on the first vehicle may be used to continuously monitor the rear situation of the first vehicle.

[0086] Step 403: Determine whether there is a rear-end collision risk based on the road condition information of the first vehicle;

[0087] Step 404: If the result of the determination in step 403 is no, that is, there is no collision risk, a stop alarm signal is issued, and the warning indicator light and the speaker are turned off to stop the light and voice alarm;

[0088] Step 405: Sending a stop alarm signal to the first vehicle, specifically, transmitting the stop alarm signal to a T-BOX terminal of the first vehicle;

[0089] Step 406: Control the first vehicle to stop the vehicle light alarm. Specifically, the T-BOX terminal forwards the stop alarm signal to the vehicle body controller to stop the vehicle light alarm.

[0090] Step 407: When the determination result of step 403 is yes or the determination result of step 401 is yes, that is, when there is a rear-end collision risk or the warning setting state is manual, the road condition information of the first vehicle is stored and reported. Specifically, the video data captured by the high-definition camera can be stored locally and reported to the Internet of Vehicles platform;

[0091] Step 408: issuing an alarm by means of a light prompt, for example, by turning on an LED module provided on the first vehicle to issue an alarm by means of a light prompt;

[0092] Step 409: Then, further determine whether the voice alarm is set to be turned on according to the warning setting instruction;

[0093] Step 410: If the determination result of step 409 is yes, that is, the voice alarm is set to be turned on, the voice alarm is turned on, and the alarm is synchronously sounded through the light prompt mode and the voice prompt mode to issue a second prompt message;

[0094] Step 411: If the result of the determination 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 the light prompt to issue a second prompt message;

[0095] Step 412: Sending the road condition information and the alarm signal to the first vehicle. Specifically, the video information and the alarm signal may be transmitted to the T-BOX terminal of the first vehicle.

[0096] Step 413: The first vehicle is then controlled to perform a vehicle light alarm. Specifically, the T-BOX terminal may forward a signal to the vehicle body controller to control the vehicle light alarm, such as turning on the brake lights to sound an alarm. At the same time, video information may be uploaded to the Internet of Vehicles platform and the central control screen.

[0097] Step 414: Communicate with the second vehicle and send a warning control signal to the second vehicle. Specifically, the pre-tensioning control signal can be sent to the central control screen of the second vehicle through the T-BOX terminal of the second vehicle through the Internet of Vehicles platform, thereby controlling the second vehicle to issue a third prompt message, such as issuing a voice reminder through the central control screen of the second vehicle.

[0098] It can be seen that the vehicle collision avoidance control method provided by the embodiment of the present invention can automatically turn on the hazard warning lights when the driver forgets to turn on the hazard warning lights when the vehicle is traveling at a slower speed or stopped by the roadside due to a breakdown. When a vehicle is detected to be oncoming, the hazard warning lights will be turned on. When a rear-end collision risk is detected, road condition information, such as the video image and speed information perceived by the camera, will be saved locally and uploaded to the Internet of Vehicles platform for cloud storage through the T-BOX terminal of the first vehicle. When a collision accident occurs, such as a rear-end collision, the user can view and download the relevant video and speed information at the time on the mobile phone APP and the vehicle's central control screen in a timely manner, which can provide a basis for accident judgment in a timely manner. In addition, when the first vehicle detects the risk of rear-end collision, while the first vehicle issues an alarm, the central control screen in the cab of the second vehicle can also be controlled by V2V technology to issue a voice alarm, so as to better remind the driver of the second vehicle to slow down in time, thereby avoiding the occurrence of collision accidents to a large extent, improving the safety and reliability of the vehicle collision avoidance control process, and making it more intelligent.

[0119] The second vehicle 605 is configured to issue a third prompt message according to the early warning control signal.

[0120] In this embodiment, the data acquisition unit 601 can be installed on the first vehicle 603 and is mainly used to obtain road condition information of the first vehicle 603. The data acquisition unit 601 can be a high-definition camera or other equipment that can obtain vehicle driving road condition information, such as radar sensors.

[0121] The control unit 602 may be an additional anti-collision controller or a vehicle controller on the first vehicle 603 , and may be specifically configured appropriately based on actual application requirements.

[0131] It can be understood that in this embodiment, information exchange can be achieved between the own vehicle T-BOX terminal 705 and the own vehicle body controller 707 and the own vehicle onboard central control screen 706 through the vehicle CAN network, and the above information interaction method is also used in the second vehicle 605.

[0132] In this embodiment, the mobile terminal 711 and the on-board central control screen 706 of the own vehicle both have soft switches such as a voice alarm mode setting switch, which can realize the sending of relevant control instructions; they can receive relevant status signals and video signals sent by the own vehicle T-BOX terminal 705, update the soft switch status according to the received status signal, and intuitively display the video on the on-board central control screen 706 of the own vehicle; the on-board central control screen 710 of the following vehicle can issue a voice reminder to the driver of the second vehicle after receiving the control signal of the first vehicle 603.

[0133] In actual application, after the vehicle T-BOX terminal 705 receives the control instruction sent by the mobile terminal 711 or the vehicle-mounted central control screen 706, it can send the control instruction to the vehicle body controller 707 in the form of a message, thereby realizing the control of the brake lights and hazard warning lights, and uploading the current status of the brake lights and hazard warning lights on the CAN bus to the vehicle network platform 604; the vehicle body controller 707 can receive the control instruction from the CAN bus and control the vehicle's brake lights and hazard warning lights to alarm.

[0134] The vehicle's T-BOX terminal 705 can also send control instructions to the anti-collision controller 702 through wireless communication technology, and forward the video information and status information fed back by the anti-collision controller 702 and the vehicle's current speed information to the mobile terminal 711 and the vehicle's onboard central control screen 706; and send information such as the vehicle's current speed, start-stop status, etc. to the anti-collision controller 702.

[0135] The anti-collision controller 702 can process the received data, such as the video signal, to determine whether there is a risk of rear-end collision or an attempt to steal the device, and issue a corresponding control signal to control the alarm.

[0136] In actual application, the user can also set whether to turn on the voice alarm through the mobile terminal 711 or the corresponding soft switch on the vehicle's central control screen 706. The relevant control instructions are forwarded to the anti-collision controller 702 through the vehicle's T-BOX terminal 705. The anti-collision controller 702 receives the setting instructions and completes the alarm mode setting.

[0137] When the manual alarm switch is off, the anti-collision controller 702 processes and analyzes the video data transmitted by the high-definition camera 701. When it determines that there is a risk of rear-end collision, it automatically saves the video and uploads the video data to the Internet of Vehicles platform 604 through the vehicle's T-BOX terminal 705. It also controls the corresponding device to alarm according to the alarm mode setting status.

[0138] When the manual alarm switch is turned on, the anti-collision controller 702 starts to save the uploaded video without making any judgment and controls the corresponding device to alarm.

[0139] When the vehicle key is not in the OFF position and the vehicle speed is less than or equal to the preset speed, if the anti-collision controller 702 detects that a second vehicle 605 is approaching in the driving direction, it can automatically control the hazard warning lights on the first vehicle 603 to turn on.

[0140] It can be seen that the vehicle collision avoidance control system provided by the embodiment of the present invention obtains the road condition information and driving status information of the first vehicle, and determines whether there is a second vehicle in the driving direction of the first vehicle and whether there is a collision risk. When there is a second vehicle or there is a collision risk, prompt information can be issued in time to provide early warning prompts to remind the driver of the second vehicle to slow down in time and pay attention to safety. Compared with traditional collision avoidance control methods, this system is more intelligent and more reliable.
