In order to improve the travel conditions of the rural areas, the village-based policy is implemented in China, and rural roads are built in almost all the rural areas. But is limited by terrain conditions and construction costs, and rural roads are mostly bidirectional nonstandard roads. When vehicles meet on the road, the safety distance between the two vehicles is usually very small, and drivers with less driving experience often cannot grasp the safety distance, so that the vehicles are scratched.
Referring to fig. 1, fig. 1 is a schematic view of an application environment provided in an embodiment of the present application, and the method for supplementing electric quantity of a battery provided in the embodiment of the present application can be applied to a vehicle meeting method and can be applied to a motor vehicle, such as a household automobile, a passenger car, a minivan, and other vehicles. The vehicle is provided with an auxiliary vehicle crossing system 100 and a detection system 103, and the auxiliary vehicle crossing system 100 is in communication connection with the detection system 200. Optionally, the auxiliary vehicle crossing system 100 and the detection system 200 are connected through a wired link, for example, the auxiliary vehicle crossing system 100 and the detection system 200 are connected through a Controller Area Network (CAN). Optionally, the auxiliary meeting system 100 and the detection system 200 may be connected via a wireless link, such as a bluetooth connection.
In the embodiment of the present application, fig. 2 is a schematic structural diagram of a vehicle provided with an auxiliary vehicle-meeting system and a detection system according to the embodiment of the present application, and as shown in fig. 2, the auxiliary vehicle-meeting system 100 may be a vehicle-mounted computer. Optionally, the vehicle-meeting assisting system 100 includes a vehicle-meeting assisting switch 101, a vehicle-meeting assisting controller 102, and a driving control mechanism. The user can actively turn on or off the assistant vehicle crossing system 100 through the assistant vehicle crossing switch 101. The auxiliary vehicle controller 102 is used for realizing automatic control of auxiliary vehicle meeting and processing data. The driving control mechanism is used for controlling the vehicle to turn according to the control instruction of the auxiliary conference controller 102. In some embodiments, the steering control mechanism includes a steering wheel 111, a steering column 112, a steering gear 113, and the like. The detection system is used to detect the environment surrounding the vehicle. Optionally, the detection system comprises an image detection subsystem and a range detection subsystem.

In an alternative embodiment, as shown in fig. 2, the image detection subsystem includes a left camera 201, a right camera 207 and a front camera 204, which are respectively disposed at the left side, the right side and the head of the vehicle body. Optionally, the left camera 201 includes one to more sub-cameras, the right camera 207 includes one to more sub-cameras, and the front camera 204 includes one to more sub-cameras. Because the visual field that the camera detector detected is less, in order to improve the precision of detecting, adopt many cameras to fix a position the discernment to the target object. The distance detection subsystem comprises a left radar 202, a right radar 206, a left front radar 203 and a right front radar 205 which are respectively arranged at the left side, the right side, the left vehicle head side position and the right vehicle head side position of the vehicle body. In some embodiments, the range detection subsystem further includes a left rear radar and a right rear radar disposed at a left position of the vehicle rear and a right position of the vehicle rear, respectively. Because the radar detector can realize great detection visual field, in order to reduce cost, the radar detector on the automobile body adopts single radar to survey.
In the embodiment of the application, each detector in the detection system can be freely combined and selected based on the characteristics of the detector and the use cost. The camera detector can be a monocular vision detector, a binocular stereo vision detector, a panoramic vision detector, an infrared camera detector and the like. The radar detector can be a laser radar detector, a millimeter wave radar detector, an ultrasonic radar detector and the like. The monocular vision detector is mainly used for detecting and identifying characteristic symbols, such as lane line detection, traffic sign identification, traffic light identification, pedestrian and vehicle detection and the like, but the reliability of vision detection is not very high.

The laser radar detector is a high-precision sensor and has the characteristics of good stability, high robustness and the like. However, the use of lidar detectors is costly.
While specific embodiments of a data processing method of the present application are described below, fig. 3 is a schematic flow chart of a vehicle crossing method provided by the embodiments of the present application, and the present specification provides the method operation steps as in the embodiments or the flow chart, but may include more or less operation steps based on conventional or non-inventive labor. The order of steps recited in the embodiments is merely one manner of performing the steps in a multitude of orders and does not represent the only order of execution. In practice, the system or server product may be implemented in a sequential or parallel manner according to the embodiments or methods shown in the figures, for example, in a parallel processor or multi-threaded environment. Specifically, as shown in fig. 3, the method may include:
s301: and receiving an auxiliary meeting instruction.
In the embodiment of the application, the auxiliary meeting instruction received by the auxiliary meeting system can be sent to a driver by operating the auxiliary meeting switch 101, so that the driver can actively start the auxiliary meeting system. The ECU is triggered to send an auxiliary vehicle crossing instruction to the auxiliary vehicle crossing system according to the fact that detection information detected by the detection system meets a preset condition, and therefore starting of the auxiliary vehicle crossing system is achieved. As an optional implementation manner, when the vehicle is in a driving process, the detection system detects an environment around the vehicle in real time, and when it is detected that there is an oncoming vehicle ahead and a distance between the oncoming vehicle and the current vehicle is smaller than a preset distance, for example, smaller than 50m, the ECU sends an auxiliary vehicle-meeting instruction to the auxiliary vehicle-meeting system to start the auxiliary vehicle-meeting system. In some embodiments, the auxiliary vehicle-meeting system is turned on and off along with the vehicle host, and when the vehicle is running, an auxiliary vehicle-meeting instruction is sent according to whether there is an incoming vehicle in a front direction, and the auxiliary vehicle-meeting instruction is used for enabling the auxiliary vehicle-meeting controller 102 to control the vehicle to realize auxiliary vehicle-meeting. Preferably, the auxiliary vehicle-crossing system is not used under most conditions, and is possibly used only when the opposite vehicle is encountered under the condition of a narrow road, so that the auxiliary vehicle-crossing instruction received by the auxiliary vehicle-crossing system can be sent to the driver by operating the auxiliary vehicle-crossing switch 101, and the driver can actively start the auxiliary vehicle-crossing system.
S303: and controlling a detection system on the vehicle to acquire image information and position information of the obstacle target on the meeting path according to the auxiliary meeting instruction.
In the embodiment of the application, in order to ensure the meeting safety of the vehicle, before determining the environment detection information on the meeting path according to the image information and the position information, the method further comprises the step of assisting the meeting controller 102 to judge the current vehicle speed of the vehicle, and if the current vehicle speed of the vehicle is greater than a threshold value, the vehicle is controlled to reduce the current vehicle speed to be less than or equal to a vehicle speed threshold value. And if the current speed of the vehicle is less than or equal to the threshold value, determining the environment detection information on the meeting path according to the image information and the position information. The threshold value of the vehicle speed can be a set value, such as 20km/h, and different threshold values can be adopted according to different road conditions. After the auxiliary vehicle-meeting system is started, the auxiliary vehicle-meeting controller 102 acquires the environmental detection data of the detection system around the current vehicle according to the auxiliary vehicle-meeting instruction. The detection system comprises an image detection subsystem and a distance detection subsystem, wherein the image detection subsystem is used for acquiring image information of an obstacle target on a meeting path. The distance detection subsystem is used for acquiring the position information of the obstacle target on the meeting path. The obstacle targets detected by the detection system include the oncoming vehicles, the stationary obstacles on the current road, the moving obstacles, the moving trends of the moving obstacles, and the like. The scene of using the auxiliary meeting vehicles is usually that the vehicles meet the oncoming vehicles under the condition of a narrow road, and under the scene, the safety distance between the vehicles is usually very small during meeting, so that the detection system needs to have higher detection precision so as to avoid safety accidents caused by larger detection errors of the detection system. As an alternative embodiment, as shown in fig. 2, the left camera 201, the right camera 207, and the front camera 204 in the image detection subsystem all use monocular vision detectors, the left radar 202 and the right radar 206 in the distance detection subsystem use laser radars, and the left front radar 203 and the right front radar 205 use millimeter-wave radars. Therefore, not only can higher detection precision be realized, but also the cost of the detection system is comprehensively considered. When the detection system is used for detecting, a target can be roughly captured quickly in a large airspace through the millimeter wave radar, and then the target is precisely tracked and measured through the laser radar and the monocular vision detector.
S305: and determining environment detection information on the meeting path according to the image information and the position information.
In the embodiment of the application, the detection system detects the image information and the position information of the obstacle object on the current path, and then the auxiliary vehicle controller 102 in the auxiliary vehicle crossing system performs data processing on the image information and the position information to determine the environment detection information. Optionally, the data processing includes, but is not limited to, noise reduction of data, compensation of data, fusion of data, and the like. In some embodiments, the detection system detects image information and location information of an obstacle object on the current path, and the detection system then data-processes the image information and location information to determine environmental detection information.
As an alternative embodiment, determining the environment detection information on the meeting path according to the image information and the position information includes: the auxiliary conference controller 102 performs feature fusion on the image information and the position information to obtain feature fusion information. The auxiliary meeting controller 102 determines environment detection information on the meeting path according to the feature fusion information. Specifically, the spatial fusion of the data of the multiple detectors is realized by establishing a precise coordinate conversion relation among a radar coordinate system, a three-dimensional world coordinate system, a camera coordinate system, an image coordinate system and a pixel coordinate system. The spatial fusion of the distance detection subsystem and the image detection subsystem is to convert the measured values of different detector coordinate systems into the same coordinate system. Because the forward image detection subsystem is mainly vision, the spatial synchronization of the multiple detectors can be realized only by converting the measuring points under the radar detector coordinate system of the distance detection subsystem into the pixel coordinate system corresponding to the camera through the coordinate system. According to the conversion relation, the conversion relation between the radar coordinate system and the camera pixel coordinate system can be obtained. Therefore, matching of the radar detector detection target in the space to the visual image detected by the image detection subsystem can be completed, and on the basis, the motion state information of the target corresponding to the radar detector detection is output. Visual information detected by the radar detector and the image detection subsystem needs to be fused in space, and the detector also needs to synchronously acquire data in time, so that time fusion is realized. As an example, the sampling period of a radar detector is 50ms, i.e. the sampling frame rate is 20 frames/second, while the sampling frame rate of a camera detector is 25 frames/second. In order to ensure the reliability of data, the sampling rate of the camera is taken as a reference, the camera selects the data cached in the last frame of the radar detector every time the camera acquires one frame of image, namely the data of the visual fusion of the radar detector and the camera detector which are sampled together is completed, and therefore the time synchronization of the data of the radar detector and the data of the camera detector is ensured. Feature fusion information is obtained through fusion of the image information and the position information, and then the auxiliary conference controller 102 can determine which obstacle targets are in the surrounding environment of the current vehicle according to the feature fusion information, and environment detection information such as the shape and the volume of the obstacle targets, the distance between the obstacle targets and the current vehicle and the like.
S307: and determining a meeting driving path according to the environment detection information and the preset safe distance.
In the embodiment of the present application, after the auxiliary meeting controller 102 acquires the environment detection information, the meeting driving path is planned according to the preset safe distance. Optionally, the preset safety distance is a minimum distance between the vehicle and the obstacle target, for example, 5 cm. Optionally, the preset safe distance is a safe distance range between the vehicle and the obstacle target when the vehicle is running, for example, 5-30 cm. And the auxiliary meeting controller 102 plans the meeting driving path of the vehicle according to the environment detection information and the preset safe distance.
As an optional implementation manner, the auxiliary meeting controller 102 determines the meeting driving path according to the environment detection information and the preset safe distance, including: the auxiliary train controller 102 determines the current position of the vehicle based on the environment detection information. The auxiliary meeting controller 102 determines whether there is an optimal meeting traveling path according to the current position of the vehicle and a preset safe distance. In the case where there is an optimal vehicle-crossing travel path, the auxiliary vehicle-crossing controller 102 determines the optimal vehicle-crossing travel path as a vehicle-crossing travel path. Specifically, the controller 102 determines, according to the environment detection information, what obstacle objects, and shape and volume of the obstacle objects, are located around the current position of the vehicle, where the obstacle objects include stationary obstacle objects, such as stones, roadblocks, roadside canals, roadside trees, and the like. Obstacle objects also include moving obstacle objects such as pedestrians, bicycles, motor vehicles, animals, and the like. For a stationary obstacle target, it is only necessary to acquire the position and shape thereof, and for a moving obstacle target, it is necessary to acquire the movement tendency thereof in addition to the position and shape thereof. And the auxiliary meeting vehicle controller 102 plans a path for the vehicle to travel according to the information and by taking the preset safe distance between the auxiliary meeting vehicle controller and the obstacle target as a path planning principle, and if the path exists, the path is the optimal meeting vehicle traveling path. The auxiliary vehicle-meeting controller 102 may use the optimal vehicle-meeting traveling path as a vehicle-meeting traveling path on which the vehicle is about to travel.
As an optional implementation manner, the auxiliary meeting controller 102 determines the meeting driving path according to the environment detection information and the preset safe distance, and further includes: under the condition that the optimal meeting advancing path does not exist in the auxiliary meeting controller 102, the auxiliary meeting controller 102 determines a meeting avoiding path according to the environment detection information and the preset safe distance. The auxiliary vehicle meeting controller 102 determines the vehicle meeting avoiding path as a vehicle meeting driving path. Specifically, the auxiliary meeting vehicle controller 102 determines what obstacle targets and shape volumes of the obstacle targets are around the current position of the vehicle through the environment detection information, and plans the optimal meeting traveling path by using a preset safety distance between the obstacle targets and the obstacle targets as a path planning principle. If the preset safe distance cannot be met, namely the optimal meeting traveling path does not exist, the current position of the vehicle cannot move ahead to finish meeting. At the moment, a meeting avoiding path can be planned according to the environment detection information and the preset safety distance so as to avoid the opposite coming vehicle and enable the opposite side to advance in advance to finish the meeting. For example, the distance between the vehicle and the oncoming vehicle is short, the vehicle cannot adjust the direction route by advancing, and the avoidance of the road space can be realized only by backing up, and at the moment, the vehicle can complete the vehicle meeting by planning a vehicle meeting avoidance path. The auxiliary vehicle controller 102 may use the vehicle on the meeting avoidance path as a vehicle meeting travel path to be traveled.
As an alternative embodiment, the auxiliary meeting controller 102 controls the vehicle to perform emergency braking when there is no meeting avoidance path in the current position of the vehicle. If the auxiliary meeting vehicle controller 102 does not draw a meeting avoidance path according to the environmental detection information and the preset safe meeting distance rules, it indicates that the current position of the vehicle cannot realize meeting avoidance through measures such as backing and the like, and the vehicle inevitably meets an obstacle target if the vehicle moves forwards, and at the moment, the vehicle can only be controlled to perform emergency braking so as to avoid safety accidents. Under the condition, the detection system still detects the surrounding environment in real time, when the moving obstacle target avoids or avoids the oncoming vehicle, the optimal meeting advancing path or meeting avoiding path is re-planned, so that the vehicles complete meeting.
S309: and controlling the vehicles to meet according to the meeting driving path.
In the embodiment of the application, after the auxiliary meeting controller 102 determines the meeting driving path of the vehicle, the auxiliary meeting controller 102 controls the driving control mechanism to drive the vehicle to move forward or backward, so that the vehicle finishes meeting. As an alternative embodiment, controlling vehicles to meet according to a meeting driving path includes: the auxiliary train controller 102 controls the detection system to acquire real-time detection information. The auxiliary meeting controller 102 controls vehicles to meet according to the meeting driving path and the real-time detection information. Specifically, after the auxiliary meeting vehicle controller 102 determines the meeting vehicle running path, the meeting vehicle running path is output to the driving control mechanism, and optionally, the meeting vehicle running path may be sent to the vehicle-mounted display screen for display. The driving control mechanism receives the meeting driving path to control the vehicles to start meeting, and meanwhile, the auxiliary meeting controller 102 controls the detection system to acquire real-time detection information. The auxiliary meeting controller 102 controls the driving control mechanism to keep the vehicle and the surrounding obstacle targets at a preset safe distance all the time, so that the vehicle can smoothly meet. In the running process of the vehicle, when the auxiliary meeting vehicle controller 102 prejudges that the vehicle is about to be smaller than the preset safe distance with the peripheral obstacle target, the driving control mechanism is controlled to actively steer and correct, so that the vehicle distance meets the safe clearance, and the vehicle can be met smoothly. When the real-time detection information acquired by the auxiliary meeting controller 102 through the detection system cannot guarantee the preset safety distance, the auxiliary meeting controller 102 sends alarm information to remind the driver to stop at the side and check the surrounding environment.
