The sight line blind area is an area outside the vehicle, which cannot be directly seen because the sight line is shielded when a vehicle driver sits in the cab. The area has four parts, namely a front part, a rear part, a left part and a right part, and the size of the area is different according to different vehicle types. Obstacles in the blind zone, whether stationary or mobile, are not visible to the driver. During the driving process of vehicles, the blind areas of sight are a great part of causes of traffic accidents of vehicles.
The common method for solving the sight blind area in the prior art is as follows: and signal lamps, warning signs or wide-angle convex lenses are arranged at the positions visible in the blind areas. The vehicle driver can only be reminded of paying attention to safety by setting the signal lamp and the warning sign, and the wide-angle convex lens can only see whether the other side has a vehicle, so that the distance of the vehicle cannot be judged, accurate vehicle running information cannot be acquired, and the vehicle driver can easily generate paralysis thought and wrong judgment, thereby causing certain safety risk.
With the rapid development of artificial intelligence technology, the realization of intelligent and automated driving of vehicles has become the key point of the development of the automobile industry. V2X (Vehicle to X) is the key technology of the future intelligent transportation system. V2X mainly studies a vehicle data transmission scheme based on a 3GPP communication protocol. V2X includes V2V (Vehicle to Vehicle communication), V2P (Vehicle to industrial Person communication), V2I (Vehicle to Infrastructure communication), and the like. If the vehicle can send the vehicle-related information of the vehicle to other vehicles and can also receive the vehicle-related information sent by other vehicles, a driver can know the running conditions of other vehicles, and therefore driving safety can be improved, congestion and vehicle energy consumption can be reduced, traffic efficiency can be improved, and the like.

The auxiliary control method and device for the vehicle provided by the embodiment of the application can be applied to a vehicle capable of communicating, and comprise the following steps: private cars, large trucks, buses, and the like.
Fig. 2 is a flowchart of an auxiliary Control method for a vehicle according to an embodiment of the present disclosure, as shown in fig. 2, the method according to the embodiment of the present disclosure may be applied to a vehicle, and in an implementation manner, the method according to the embodiment of the present disclosure may be executed by an Electronic Control Unit (ECU) of the vehicle, and the method according to the embodiment of the present disclosure includes:
s201, the first vehicle receives vehicle related information sent by N second vehicles.
And N is an integer greater than or equal to 1.
In the running process of the first vehicle, vehicle-related information sent by N second vehicles, the distance between the first vehicle and the N second vehicles is smaller than or equal to a first preset distance, and meanwhile, the first vehicle can also send the vehicle-related information of the first vehicle to the N second vehicles. For example, the first preset distance is 300m, and there are 10 second vehicles whose distance from the first vehicle is less than or equal to 300m, and the first vehicle may communicate with the 10 second vehicles to obtain the information related to the 10 second vehicles.
In this embodiment, the first vehicle is equipped with a PC5 interface device, the PC5 interface device is controlled by the ECU of the first vehicle, each of the second vehicles is equipped with a PC5 interface device, and the PC5 interface device is controlled by the ECU of the second vehicle. The ECU of the first vehicle may receive the vehicle-related information of the vehicle transmitted from the second vehicle through the PC5 interface device through the PC5 interface device, and the ECU of the first vehicle may also transmit the vehicle-related information of the first vehicle to the second vehicle through the PC5 interface device.
Currently, in the V2X related specification of 3GPP (3rd Generation Partnership Project), a security protection mechanism is defined for point-to-point communication of PC5 interfaces. V2V communication in principle, communication can be made via the Uu interface (interface between user equipment and base station) and the PC5 interface (interface between user equipment and user equipment). The direct communication mode based on the PC5 is to support communication such as V2V, V2I and V2P on a unified 5.9GHz intelligent traffic system frequency band, and becomes a cellular user or cellular network assistance without using a SIM card. By arranging the PC5 interface equipment in the vehicle and the road side unit, the vehicles on the road can be directly communicated, and vehicle drivers can quickly and efficiently acquire the driving conditions of the related vehicles and perform corresponding operations in advance so as to reduce the safety risk.
The PC5 interface device is used for collecting information related to N second vehicles with the distance between the first vehicle and the second vehicle being less than or equal to a first preset distance, and the first vehicle and the second vehicle being less than or equal to the first preset distance can communicate through the PC5 interface device, namely, the first vehicle and the second vehicle being less than or equal to the first preset distance can receive or send the information related to the vehicles through the PC5 interface device during the driving process of the vehicles.
The ECU is also called a traveling computer or a vehicle-mounted computer, etc. The ECU is a microcomputer controller special for automobiles and comprises an input circuit, a microcomputer, an output circuit and the like. The input circuit receives signals input by sensors and other devices, filters and amplifies the signals, and then converts the signals into a certain input level. The signal input from the sensor to the input circuit of the ECU has both an analog signal and a digital signal, and an analog/digital converter in the input circuit may convert the analog signal into a digital signal and then transmit it to the microcomputer. The microcomputer performs arithmetic processing on the preprocessed signals and sends the processed data to an output circuit.
In this embodiment, the input signal of the ECU of the first vehicle includes: and the ECU of the first vehicle performs operation processing on the received vehicle-related information of the second vehicle and outputs the processed vehicle-related information of the second vehicle through the PC5 interface device.
Optionally, the vehicle-related information includes one or more of: position information of the vehicle, vehicle travel information; the vehicle travel information includes one or more of: vehicle speed information, steering wheel action information, accelerator action information, brake action information, and driving direction information.
During the running process of the first vehicle, the position information of the second vehicle, which is currently located by N vehicles, and the running information of the second vehicle may be received, for example: the second vehicle may be specific vehicle speed data, whether a steering wheel is turned left or right, whether an accelerator is stepped on for acceleration, whether a brake is stepped on for deceleration, and a traveling direction of the second vehicle, and whether the second vehicle is the same as the traveling direction of the first vehicle may be determined from the received traveling direction of the second vehicle.
S202, determining the vehicle running condition of the first vehicle within the preset distance range according to the vehicle related information of the N second vehicles.
After the ECU of the first vehicle receives the vehicle-related information of the second vehicle through the PC5 interface device, the ECU of the first vehicle may perform an operation based on the received vehicle-related information of the second vehicle to obtain the traveling condition of the second vehicle. For example: if the vehicle speed information of the second vehicle, which receives that the distance between the front and the first vehicle is smaller than or equal to the preset distance, is reduced from 50km/h to 20km/h, and the distance between the second vehicle and the first vehicle is smaller than or equal to a safe distance, for example: when the distance is 20m, the ECU can calculate that the second vehicle in front is running at a low speed, which may cause a potential safety hazard to the first vehicle, and needs to prompt a vehicle driver of the first vehicle to perform corresponding operation in time.
Optionally, the preset distance range of the first vehicle may refer to that the distance between the first vehicle and the first vehicle is less than or equal to a first preset distance. One possible implementation manner of the foregoing S202 is: and determining the vehicle running condition of the vehicle with the distance between the vehicle and the first vehicle being less than or equal to a first preset distance according to the vehicle-related information of the N second vehicles.
Optionally, the preset distance range of the first vehicle may refer to that the distance between the first vehicle and the first vehicle is less than or equal to a second preset distance, and the second preset distance is less than the first preset distance. One possible implementation manner of the foregoing S202 is: determining M second vehicles within a second preset distance from the first vehicle according to the position information of the N second vehicles and the position information of the first vehicle, wherein M is an integer which is greater than or equal to 1 and less than or equal to N; and determining the vehicle running condition according to the vehicle running information of the M second vehicles.
Each vehicle is equipped with a PC5 interface device to enable short-range communication between vehicles. The distances between the N second vehicles and the first vehicle can be determined from the position information of the N second vehicles and the position information of the first vehicle. And determining M second vehicles which are less than or equal to a second preset distance from the first vehicle and can influence the driving process of the first vehicle.
For example: the first preset distance is 300m, the first vehicle can receive information related to 10 second vehicles, during the running process of the first vehicle, according to the running condition of the first vehicle, it is determined that a second vehicle with a distance between the second vehicle and the first vehicle being less than or equal to a second preset distance of 100m can affect the running of the first vehicle, and it can be determined that a second vehicle with a distance between the second vehicle and the first vehicle being less than or equal to a second preset distance of 3 second vehicles, so that the running condition of the 3 second vehicles with the distance between the second vehicle and the first vehicle being less than or equal to 100m needs to be concerned, and the running condition of other second vehicles outside the range of 100m can be neglected temporarily. It should be noted that, if the traveling speed of the first vehicle is faster, the second preset distance may be larger.
Optionally, the vehicle running condition includes a running condition of each of the M second vehicles and relative position information of each second vehicle and the first vehicle.
The vehicle running condition includes a running condition of each of the M second vehicles, such as: the relative position information of each second vehicle and the first vehicle is to determine where the second vehicle is located in the first vehicle, for example, if the second vehicle in the front sight blind area brakes while the first vehicle is traveling, the first vehicle also needs to brake to avoid rear-end collision if the second vehicle in the front sight blind area brakes.
Optionally, the vehicle-related information further includes a license plate number of the vehicle; the vehicle driving condition further includes a license plate number of each second vehicle.
S203, outputting prompt information according to the vehicle running condition, wherein the prompt information is used for prompting the vehicle running condition within the preset distance range of the first vehicle.
When the ECU of the first vehicle judges that the second vehicle can generate potential safety hazard to the first vehicle according to the vehicle running condition of the second vehicle, the first vehicle outputs prompt information. The prompt information is used for prompting the vehicle running condition of the first vehicle within the preset distance range, and the vehicle driver of the first vehicle performs corresponding operation according to the prompt information to reduce the safety risk. The prompt message may be an indicator light message displayed on the dashboard of the vehicle directly in front of the line of sight of the driver of the vehicle, for example: when the indicator light is red, the abnormal condition of the front vehicle is shown, and the vehicle needs to slow down; or the sound equipment on the first vehicle may play the sound, for example: "there is an abnormal situation in the front, please decelerate. And are not limited herein.
Fig. 3 is an ECU interface display diagram of a vehicle provided in an embodiment of the present application, as shown in fig. 3.
The ECU interface display of the vehicle is divided into two parts, the left side is an environment simulation interface of the vehicle, and the right side is a driving direction display interface of the vehicle. The vehicle represents a first vehicle, and when the distance between a second vehicle and the first vehicle is less than or equal to a first preset distance, for example: the first preset distance is 300m, and the driving direction of the first vehicle and the driving direction of the second vehicle are displayed on the display interface on the right side. When the distance between the second vehicle and the first vehicle is less than or equal to a second preset distance, for example: the second preset distance is 100m, and the icon of the second vehicle is displayed on the left interface. When the driving directions of the first vehicle and the second vehicle are the same, a single lane is displayed, and when the driving directions of the first vehicle and the second vehicle are opposite, a double lane is displayed.
Optionally, the left interface of the ECU interface display of the vehicle of this embodiment may also display speed information, license plate number, brake operation information, steering wheel operation information, and the like of the second vehicle. For example: the brake 20 of the shan AB30B9 represents that a second vehicle with the license plate number of shan AB30B9 is stepping on the brake, the speed of the vehicle is 20km/h, a vehicle driver of a first vehicle can obtain the brake of the second vehicle according to vehicle information of the second vehicle on an interface display picture, and the first vehicle needs to be braked to avoid rear-end collision.
Optionally, the method of this embodiment may further include: displaying icons of a plurality of second vehicles; detecting a first operation instruction input by a user based on an icon of a target second vehicle, wherein the first operation instruction comprises notification information, and the first operation instruction is used for sending the notification information to the target second vehicle. And sending the notification information to the target second vehicle according to the first operation instruction.
When a user needs to send notification information to a target second vehicle according to acquired related information of the second vehicle, a first operation instruction may be input to the first vehicle, where the first operation instruction includes the notification information, and when a preset distance between the target second vehicle and the first vehicle is less than or equal to a second preset distance, an icon of the second vehicle may be displayed on a left side interface of an ECU interface display of the first vehicle shown in fig. 3, and after the target second vehicle is found on the left side interface according to a relative position of the second vehicle and the first vehicle, the icon of the target second vehicle may be directly clicked, an appropriate option is selected, and the first vehicle may send the notification information to the target second vehicle. The second vehicle can make corresponding operation according to the notification information sent by the first vehicle. For example: when the second vehicle opens the high beam and influences the sight of the driver of the first vehicle, the first vehicle can send the warning information of the high beam to the second vehicle, and after the second vehicle receives the warning information, the high beam can be closed in time.
According to the vehicle auxiliary control method provided by the embodiment of the application, a first vehicle can receive the related information of N second vehicles, and the vehicle running condition within the preset distance range of the first vehicle can be determined according to the vehicle related information of the N second vehicles; and outputting prompt information according to the vehicle running condition. The vehicle can acquire the vehicle running condition around the vehicle by receiving the vehicle related information sent by other vehicles, so that the accurate and effective vehicle running condition of the second vehicle with the blind sight area can be provided for the vehicle driver, and the safety risk can be reduced.
Fig. 4 is a schematic diagram of an assist control method for a vehicle according to an embodiment of the present application, as shown in fig. 4.
When the vehicles 1, 2 and 3 run in a queue, the vehicle 1 cannot see the running condition of the vehicle 3 due to the shielding of the vehicle 2, and the vehicle 3 is a blind spot of the vehicle 1. If the vehicle 3 brakes emergently, the driver of the vehicle 2 responds and can decelerate and brake in time, the driver of the vehicle 1 cannot directly see the braking action of the vehicle 3, and only when the driver observes the braking action of the vehicle 2, the vehicle 1 can recognize the need of braking. If the distance between the vehicles is close and the speed is high, the vehicle 1 can easily collide with the vehicle 2.
Fig. 5 is a schematic diagram of an assist control method for a vehicle according to another embodiment of the present application, as shown in fig. 5.
When the vehicles 1, 2, 3 are driving in a queue, the driver of the vehicle 2 reacts if the vehicle 3 brakes suddenly, and the driver of the vehicle 1 reacts only when observing that the vehicle 3 is stationary if the left-hand lane is changed. If the distance is too close, the speed is fast, and the vehicle 1 can easily end up with the vehicle 3.
In the embodiment of fig. 4 and 5, vehicles 1, 2 and 3 are queued to travel on the highway, all support the direct communication system of the PC5 protocol, and all have established connection, and the conditions for short-distance communication are satisfied between the vehicles, i.e. the ECU of vehicle 1 can receive the vehicle travel information of vehicles 2 and 3 through the PC5 interface device. When the vehicle 3 needs to be braked due to an accident (for example, an obstacle exists in the front), and the vehicle 1 does not observe the action of the vehicle 2, the ECU of the vehicle 1 receives the vehicle-related information of the vehicle 3 through the PC5 interface device, wherein the vehicle-related information includes the position information, the speed information and the braking information of the vehicle 3, the ECU of the vehicle 1 can calculate that the vehicle 3 is running at a low speed through the received vehicle-related information of the vehicle 3, and then outputs prompt information, for example, a voice prompt is sent through an audio device: "there is the abnormal situation in the front, please slow down and walk", the vehicle driver can make corresponding operation according to the situation.
According to the vehicle-related information of the vehicle 3, the ECU of the vehicle 1 can determine the driving condition of the vehicle 3 through calculation, which mainly includes the following conditions: the vehicle 3 runs at a high speed, namely when the speed is more than 100km/h, the safe distance is more than 100 meters; the vehicle 3 is travelling fast, i.e. above 60km/h, the safe headway is numerically equal to the vehicle speed, for example: the speed of the vehicle 3 is 80km/h, and the safe vehicle distance is 80 meters; the vehicle 3 runs at a medium speed, namely when the speed is about 50km/h, the safe distance is not less than 50 meters; the vehicle 3 runs at a low speed, namely when the speed is below 40km/h, the safe distance is not less than 30 meters; the vehicle 3 drives at tortoise speed, namely when the speed is below 20km/h, the safe distance is not less than 10 meters.
According to the distance between the vehicle 1 and the vehicle 3 and the speed of the vehicle 3, when the vehicle 3 is braked, if the distance between the vehicle 1 and the vehicle 2 is less than or equal to the safe distance, the vehicle 1 can be decelerated in advance according to the prompt information, so that the rear-end collision is avoided.
Fig. 6 is a schematic diagram of an assist control method for a vehicle according to still another embodiment of the present application, as shown in fig. 6.
When the vehicles 1, 2 are running on the bidirectional single lane, the vehicle 1 is located behind the vehicle 2, and the vehicle 2 is a large truck, so that the vehicle 1 cannot visually see whether there is an incoming vehicle on the left lane. If the vehicle 1 wants to overtake, it must be ensured that there is no vehicle meeting in the left lane, otherwise an accident is easily caused during overtaking.
Overtaking in an urban road, and if the speed of the vehicle is lower than 40km/h, ensuring the distance of at least 2 parking spaces, namely about 10 meters; if the vehicle speed is 40-60km/h, the distance between vehicles is at least ensured to be more than 20 meters; if the vehicle speed exceeds 60km/h, the vehicle distance of more than 60 meters is at least kept.
In this embodiment, the vehicles all support the direct communication system of the PC5 protocol, and all have established connection, and the conditions of short-distance communication are satisfied between the vehicles, that is, the ECU of the vehicle 1 can receive the vehicle driving information of the vehicle 2 and other vehicles through the PC5 interface device, and the vehicle 1 can display a display image through the ECU interface to see whether there is a vehicle meeting in the left lane, and whether there is another vehicle in a certain distance in front of the vehicle 2, for example: no other vehicles exist within a distance of 50m in front of the vehicle 2, so that the vehicle 1 can return to the lane after overtaking. If other vehicles are not seen by naked eyes, and meanwhile, according to the ECU interface display image, the vehicle meeting in the left lane can be seen, no other vehicle exists in a certain distance in front of the vehicle 2, or the vehicle meeting in the left lane and the other vehicle in front of the vehicle 2 can be seen, but according to the ECU interface display image, the distance of the vehicle meeting in the left lane is far, and the distance of the vehicle existing in front of the vehicle 2 is also far, the vehicle 1 can overtake. Namely, the driver of the vehicle can judge when the vehicle can safely overtake according to the display image of the ECU interface, thereby avoiding the possibility of accidents.
