The invention provides a vehicle U-turn path generation method and device and a vehicle, and relates to automatic driving and intelligent traffic in the technical field of artificial intelligence. According to the specific implementation scheme, according to a first obstacle in a vehicle U-turn scene, a U-turn starting point for a vehicle to avoid the first obstacle is obtained, according to the U-turn starting point and the size attribute of an intersection in the vehicle U-turn scene, a bending point of the vehicle is determined, the bending point is a position point at which the vehicle starts to go straight, and according to the U-turn starting point and the bending point, the vehicle is driven to go straight. According to the method, the vehicle U-turn path is generated, the defect that smooth passing of the vehicle possibly cannot be completed due to the fact that the virtual U-turn line is adopted to complete vehicle U-turn can be avoided, the generated vehicle U-turn path can avoid the first obstacle, the size condition of the intersection is considered, the effectiveness and the reliability of the vehicle U-turn path are achieved, and the vehicle U-turn path is more accurate. Therefore, the vehicle is smooth and safe when driving based on the vehicle U-turn path.

    本公开提供了一种车辆掉头路径的生成方法、装置及车辆,涉及人工智能技术领域中的自动驾驶和智能交通。具体实现方案为:根据车辆掉头场景中的第一障碍物,获取车辆避开第一障碍物的掉头起始点,根据掉头起始点、以及车辆掉头场景中的路口的大小属性,确定车辆的出弯点,其中,出弯点为车辆开始直行的位置点,根据掉头起始点和出弯点,生成车辆掉头路径,可以避免采用虚拟掉头线完成车辆掉头所造成的可能无法完成车辆的顺利通行的弊端,生成的车辆掉头路径既可以避开第一障碍物,还考虑了路口的大小情况,实现了车辆掉头路径的有效性和可靠性,以使得当车辆基于车辆掉头路径行驶时,通畅且安全。
