Longitudinal speed control method and device for automatic parking and vehicle

The invention relates to the field of intelligent automobiles, in particular to a longitudinal speed control method and device for automatic parking and a vehicle. According to the longitudinal speed control method for automatic parking, the path length of a parking path of the vehicle is obtained, and the longitudinal speed of the vehicle in the parking path is determined based on the path length and preset parking information; and controlling the vehicle to run according to the longitudinal speed through a plurality of controllers. According to the method, the vehicle can be started and decelerated stably, the planned speed can be tracked accurately, parking of the vehicle can be more accurate and stable, and therefore the experience feeling of passengers can be improved. 本申请涉及智能汽车领域，涉及一种自动泊车的纵向速度控制方法、装置和车辆，该自动泊车的纵向速度控制方法通过获取车辆泊车路径的路径长度，基于路径长度和预设泊车信息确定车辆在泊车路径的纵向速度，通过多个控制器根据纵向速度控制车辆行驶。本申请不仅可以使车辆能够平稳的起步、减速和精确的跟踪所规划的速度，还可以使车辆的泊车更加精确和平稳，从而可以提高乘客的体验感。
