[0044] The vehicle auxiliary control method proposed in this embodiment obtains the vehicle's driving information to calculate the vehicle's braking and stopping position, and combines the traffic light information, the first stop line position and the second stop line position to control the target vehicle's driving strategy when passing through the intersection. The formulated vehicle driving strategy is more stable and efficient, and the intersection traffic control device used is easy to implement, which can significantly reduce the risk of autonomous driving vehicles passing through intersections.

The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0046] See also Figure 1 , is a flow chart of a vehicle auxiliary control method provided in an embodiment of the present application, which may specifically include:

[0047] S110, obtaining driving information of the target vehicle, wherein the driving information includes speed information, vehicle position information and braking acceleration information;

[0048] Exemplarily, vehicle driving information such as the speed information, vehicle position information and brake acceleration information of the target vehicle is obtained. The speed information can be determined by the vehicle's own speed measured, the vehicle position information can be determined by relying on a high-precision map and GPS position, and the brake acceleration information is the maximum brake acceleration information without affecting the passengers' riding experience, which can be obtained based on the daily driving style statistics of the driver of the target vehicle, or can be pre-set by the developer or driver.

[0049] S120, obtaining traffic light information of a target intersection, wherein the traffic light information includes traffic light color information;

[0050] For example, the signal light information of the target intersection is obtained, that is, the color information of the signal light of the target intersection is identified, including red, green and yellow. The color information can be obtained based on the vehicle driving picture obtained by the camera in front of the vehicle and based on the intelligent recognition algorithm. Alternatively, the target vehicle can communicate with the signal light of the target intersection, and the target intersection includes the instruction of the signal light color information.

[0051] S130, obtaining a braking parking position through the speed information and the braking acceleration information;

[0052] For example, the vehicle's speed information and brake acceleration information can be used to calculate the position where the vehicle will eventually stop if the brakes are applied immediately at the vehicle's current position and current speed. The braking stop position car_stop_position can be obtained by adding the vehicle's current position car_position to the braking distance car_braking_distance. The braking distance car_braking_distance can be calculated by the formula car_braking_distance = car_v*car_v / (2*a), where a is the braking acceleration of the autonomous driving vehicle and car_v is the vehicle's speed information.

[0053] S140. Control the driving strategy of the target vehicle based on the brake stop position, the traffic light information, the first stop line position and the second stop line position, wherein the first stop line is a real stop line corresponding to the driving direction of the target vehicle at the target intersection, and the second stop line is a virtual stop line that is a preset distance from the first stop line and is behind the driving direction.

[0054] Exemplarily, when determining the driving strategy, the braking stop position, the positional relationship with the first stop line position and the second stop line position, and the signal light information are considered. The first stop line is a real stop line that actually exists in the intersection, and the second stop line is a virtual stop line close to the intersection side and preset at a distance from the first stop line. By reasonably setting the preset distance, the relationship between the first stop line position and the second stop line position and the braking stop position, combined with the signal light information, the vehicle driving strategy formulated is more stable and efficient, and the intersection traffic control device used is easy to implement, which can significantly reduce the risk of autonomous driving vehicles passing through intersections.

[0055] In summary, the vehicle auxiliary control method proposed in this embodiment obtains the vehicle's driving information to calculate the vehicle's braking and stopping position, and combines the traffic light information, the first stop line position and the second stop line position to control the target vehicle's driving strategy when passing through the intersection. The formulated vehicle driving strategy is more stable and efficient, and the intersection traffic control device used is easy to implement, which can significantly reduce the risk of autonomous driving vehicles passing through intersections.

[0056] In some examples, the preset distance is determined based on a distance between a first stop line and a lane line in a second direction closest to the first stop line, the second direction intersecting the driving direction.

[0057] For example, Figure 2 As shown, the position of the second stop line can be determined by the lane line that intersects the current driving direction and is closest to the position of the first stop line, that is, the figure shows a set of the first stop line and the second stop line. If the second stop line is set in this way, even if the vehicle stops behind the first stop line but before the second stop line, it will not affect the normal driving of vehicles in the direction intersecting with it, greatly improving the safety and flexibility of autonomous driving.

[0058] In summary, the vehicle auxiliary control method proposed in the embodiment of the present application determines the second stop line according to the lane line in the crossing direction, so that the safety and flexibility of the vehicle auxiliary control scheme combining the first stop line and the second stop line are improved.

[0059] In some examples, the driving strategy of controlling the target vehicle based on the braking stop position, the signal light information, the first stop line position, and the second stop line position includes:

[0060] When the signal light color information is yellow, the braking stop position is before the second stop line, and the target vehicle has not passed the first stop line, controlling the target vehicle to brake;

[0061] and / or,

[0062] When the signal light color information is yellow and the brake stop position is behind the second stop line, controlling the target vehicle to pass through the target intersection;

[0063] and / or,

[0064] When the color of the signal in the traffic light information is yellow, the brake stop position is between the second stop line and the first stop line, and the target vehicle is between the first stop line and the second stop line, the target vehicle is controlled to continue to execute the current driving strategy.

[0065] Exemplarily, when the traffic light color information is green, the target vehicle is controlled to pass through the target intersection.

[0066] When the signal light color information is yellow, the target vehicle can be controlled according to Table 1:

[0067]

[0068]

[0069] Table 1

[0070] The first stop line position is first_stopline_position, the second stop line position is second_stopline_position, and the brake stop position is car_stop_position.

[0071] When the traffic light color information is yellow, the brake stop position is before the second stop line and the target vehicle has not passed the first stop line, the target vehicle is controlled to brake. It should be noted that the brake stop position before the second stop line includes the brake stop position before the first stop line and the brake stop position between the first stop line and the second stop line.

[0072] When the traffic light color information is yellow and the braking stop position is behind the second stop line, the target vehicle is controlled to pass through the target intersection. That is, no matter where the vehicle is at this time, as long as the calculated braking stop position is behind the second stop line, the vehicle is controlled to pass through the intersection.

[0073] When the signal color in the traffic light information is yellow, the brake stop position is between the second stop line and the first stop line, and the above-mentioned target vehicle is between the first stop line and the second stop line, the target vehicle is controlled to continue to execute the current driving strategy, that is, when the vehicle drives to the first stop line and the second stop line and the brake stop position is between the first stop line and the second stop line, if the stop command is executed, the vehicle stops, and if the stop command is not executed, the vehicle passes.

[0074] In some examples, the driving strategy of controlling the target vehicle based on the braking stop position, the signal light information, the first stop line position, and the second stop line position includes:

[0075] When the signal light color information is red and the target vehicle has not passed the first stop line, controlling the target vehicle to brake;

[0076] and / or,

[0077] When the signal light color information is red and the target vehicle passes the first stop line, controlling the target vehicle to continue to execute the current driving strategy;

[0078] and / or,

[0079] When the signal light color information is red and the target vehicle passes through the second stop line, the target vehicle is controlled to pass through the target intersection.

[0080] Exemplarily, when the traffic light is red, the vehicle is controlled to travel according to Table 2.

[0081]

[0082] Table 2

[0083] When the traffic light color information is red and the target vehicle has not passed the first stop line, the target vehicle is controlled to brake, that is, the braking stop position can be ignored at this time, and the braking operation can be performed directly to avoid danger caused by violations.

[0084] When the traffic light color information is red and the target vehicle has passed the first stop line, the target vehicle is controlled to continue to execute the current driving strategy. It should be noted that passing the first stop line includes passing the first stop line but not passing the second stop line and having passed the second stop line. Executing the current driving strategy includes braking if a stop command has been executed and passing if a stop command has not been executed.

[0085] When the signal light color information is red and the target vehicle passes through the second stop line, the target vehicle is controlled to pass through the target intersection.

[0086] In some examples, the signal light information further includes signal light countdown information;

[0087] The driving strategy of controlling the target vehicle based on the braking stop position, the signal light information, the first stop line position and the second stop line position includes:

[0088] When the signal light color information is green, the target vehicle has not passed the first stop line, and cannot pass the first stop line within the countdown information, the target vehicle is controlled to brake.

[0089] Exemplarily, when the countdown of the traffic light can be obtained and the color of the traffic light is green, the target vehicle can be controlled to travel in the manner of Table 3.

[0090]

[0091]

[0092] Table 3

[0093] When the traffic light color information is green, the target vehicle has not passed the first stop line, and cannot pass the first stop line within the countdown information, the target vehicle is controlled to brake. In other cases, the target vehicle is controlled to pass the target intersection.

[0094] In some examples, the signal light information further includes signal light countdown information;

[0095] The driving strategy of controlling the target vehicle based on the braking stop position, the signal light information, the first stop line position and the second stop line position includes:

[0096] When the traffic light color information is yellow, the target vehicle has not passed the first stop line, and the target vehicle can pass the first stop line within the countdown information, the target vehicle is controlled to pass the target intersection.

[0097] Exemplarily, when the countdown of the traffic light can be obtained and the color of the traffic light is yellow, the target vehicle can be controlled to travel in the manner of Table 4.

[0098]

[0099]

[0100] Table 4

[0101] When the traffic light color information is yellow, the target vehicle has not passed the first stop line and can pass the first stop line within the countdown information, the target vehicle is controlled to pass the target intersection. In other cases, the same control scheme is adopted as when the countdown information is not obtained.

[0102] In some examples, the vehicle position information, the first stop line position, and the second stop line position are acquired based on a high-precision map and GPS position information corresponding to the target vehicle.

[0103] For example, Figure 3 As shown, it is a schematic diagram of the principle of a vehicle obtaining vehicle position information, first stop line information, second stop line information and / or signal light information, the GPS coordinates of the vehicle are obtained through a GPS signal receiver, and the precise position information, first stop line information and second stop line information of the vehicle are obtained through a high-precision map in a storage device and a computer control program, combined with the processing function of a processor. At the same time, the image of the target intersection captured by the camera is combined with a corresponding processing algorithm to identify the signal light information.
