The invention provides a vehicle driving risk assessment method and device, electronic equipment and edge computing equipment, and relates to the field of computers, in particular to the field of automatic driving and intelligent traffic. According to the implementation scheme, in response to an obstacle detected in the driving process of a main vehicle, the first distance between the obstacle and the main vehicle in the longitudinal direction is obtained, and the longitudinal direction is the lane line extending direction of a lane where the main vehicle is located; the speeds of the obstacle and the main vehicle in the longitudinal direction are obtained; determining a safe distance between the main vehicle and the obstacle based on the speeds of the obstacle and the main vehicle in the longitudinal direction, and a preset time headway and relative collision time; and determining whether the obstacle has a safety risk for the host vehicle based on the safety distance and the first distance. The relative collision time represents preset safety time when speed difference exists between the main vehicle and the obstacle, and the time headway represents preset time difference when the main vehicle and the front end of the obstacle pass through the same place.
本公开提供了一种车辆驾驶风险评估方法、装置、电子设备及边缘计算设备,涉及计算机领域,尤其涉及自动驾驶、智能交通领域。实现方案为:响应于在主车行驶过程中检测到障碍物,获取障碍物与主车在纵向方向上的第一距离,纵向方向为主车所在车道的车道线延伸方向;获取障碍物和主车各自在纵向方向上的速度;基于障碍物和主车各自在纵向方向上的速度、以及预先设置的车头时距和相对碰撞时间,确定主车与障碍物的安全距离;以及基于安全距离以及第一距离确定障碍物对于主车是否存在安全风险。相对碰撞时间表示主车与障碍物存在速度差时的预设安全时间,车头时距表示主车与障碍物的前端通过同一地点的预设时间差。
