Embodiment Construction

[0046] In the following, only some exemplary embodiments are briefly described. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Accordingly, the drawings and descriptions are to be regarded as illustrative in nature and not restrictive.

[0047] figure 1 It is a flow chart of the vehicle control method provided by the embodiment of the present invention. like figure 1 As shown, the vehicle control method of the embodiment of the present invention includes:

[0048] Step S110, obtaining the safe time window corresponding to the U-turn of the vehicle;

[0049] Step S120, judging whether there is an obstacle in the opposite lane within the safety time window that can reach the position where the vehicle is in the U-turn lane;

[0050] Step S130, controlling the vehicle based on the judgment result.

[0051] In the intersection clearance sc...

Abstract

Embodiments of the present invention provide a vehicle control method and device, and a computer readable storage medium. The vehicle control method includes the steps of: obtaining a safety time window corresponding to vehicle U-turn; determining whether an obstacle in the opposite lane can reach a position where the vehicle U-turn lane is located in the safe time window or not; and controlling the vehicle based on the result of the determination. According to the embodiment of the invention, a targeted decision-making method for avoiding the straight traffic flow in the vehicle U-turn sceneis employed to improve the safety and traffic efficiency of the vehicle when the vehicle turns around at the intersection, reduce the probability of accidents and make the driving of the vehicle saferand smoother.

Description

technical field [0001] The present invention relates to the technical field of unmanned driving, in particular to a vehicle control method, device and computer-readable storage medium. Background technique [0002] In the intersection clearance scenario, the traffic environment is relatively complex, and the vehicle needs to avoid obstacles in the opposite lane when turning around at the intersection. The vehicle system in the prior art still adopts a conventional control method when making a U-turn, that is, controlling the steering and speed of the vehicle by using the road information and obstacle information obtained through perception. Because the vehicle system of the prior art does not implement targeted control decisions in the U-turn scene, the safety and traffic efficiency of the vehicle when making a U-turn at the intersection are reduced, which may lead to poor traffic flow and increase the occurrence of traffic accidents risks of.
