Embodiment Construction
[0054] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0055] figure 1 It is a flow chart of a vehicle collision avoidance method provided by an embodiment of the present invention, which can be executed by a vehicle-mounted terminal. Such as figure 1As shown, the method includes:
[0056] S11: Acquiring information on obstacles in front of the vehicle in real time.
[0057] The front obstacle information includes the distance L between the midpoint of the front obstacle within the detection range of the front radar of the vehicle and the vehicle along the direction perpendicular to the central axis of the vehicle, and the distance between the midpoint and the center point of the front of the vehicle The angle θ between the line connecting the line and the central axis of the vehicle, a...

The invention discloses a vehicle collision avoidance method and a vehicle collision avoidance device, a computer-readable storage medium, and belongs to the automobile field. The method comprises thefollowing steps: obtaining obstacle information in front of a vehicle in real time; judging whether the vehicle should be controlled to avoid collision according to the obstacle information in frontof the vehicle; when it is necessary to control the vehicle to avoid collision, obtaining the road condition information; determining steering wheel steering according to road condition information; determining a steering wheel turning angle according to the obstacle information in front of the vehicle; contorlling steering wheel rotation according to the determined steering wheel steering and steering wheel angle. as that obstacle information in front of the vehicle is acquired in real time, the obstacle information in front of the vehicle gradually changes during the collision avoidance process, so that the determined steering wheel rotation angle also gradually changes, and in the collision avoidance process, the collision avoidance device of the vehicle is realized by continuously adjusting the steering wheel rotation angle without carrying out path planning, which is beneficial to improving the operation efficiency of the collision avoidance device of the vehicle.
Description
technical field [0001] The invention relates to the field of automobiles, in particular to a vehicle collision avoidance method and device, and a computer-readable storage medium. Background technique [0002] Cars are the most common means of transportation and are closely related to people's lives. With the development of science and technology, automatic driving and unmanned driving have appeared. [0003] In order to ensure the safe and normal driving of vehicles, in automatic driving and unmanned driving, it is usually necessary to realize functions such as vehicle collision avoidance, automatic cruise, and automatic parking. [0004] In the existing vehicle collision avoidance, the camera is usually used to capture the picture in front of the vehicle. By analyzing the picture and combining the obtained lane line information (such as roadside line, double yellow line, single solid line, etc.), the vehicle is The planning of the driving path, and then control the vehic...
