A method, system and device for assisting in reducing a vehicle distance and a computer readable storage medium belong to the field of intelligent driving, and comprise the following steps: acquiring the speed of a vehicle, the speed of a front obstacle and the relative distance between the vehicle and the front obstacle; a corresponding psychological safety distance is obtained according to the vehicle speed of the vehicle, and when it is judged that the psychological safety distance is larger than the emergency braking distance of an emergency braking function unit of the vehicle and smaller than the relative distance, the function of assisting in reducing the vehicle distance is started in combination with preset conditions; the auxiliary vehicle distance reducing function is to reduce the speed of the vehicle to the speed of a front obstacle by using an auxiliary acceleration, and calculate the auxiliary acceleration when the sum of the driving distance of the vehicle when the speed of the vehicle is reduced to the speed of the front obstacle and the psychological safety distance is not greater than the relative distance. A new function of assisting in reducing the vehicle distance can be added on the basis of the existing emergency braking function of the vehicle, collision with a front obstacle is avoided, and the driving safety is improved.
一种辅助缩小车距方法、系统、设备及计算机可读存储介质,属于智能驾驶领域,包括获取自车车速、前方障碍物速度、以及自车与前方障碍物的相对距离;根据自车车速,得到相应的心理安全距离,并在判断该心理安全距离大于自车的紧急制动功能单元的紧急制动距离且小于所述相对距离时,结合预设条件,启动辅助缩小车距功能;所述辅助缩小车距功能为利用辅助加速度降低自车车速至前方障碍物速度,并以自车车速降至前方障碍物速度时的自车行驶距离和所述心理安全距离的总和不大于所述相对距离计算得到所述辅助加速度。本申请能够在自车现有的紧急制动功能基础上增加新的辅助缩小车距功能,避免与前方障碍物碰撞,提高驾驶安全性。
