The invention provides a vehicle and a vehicle speed control method and device thereof. The method comprises the following steps of obtaining a transverse position error and a course angle error of the vehicle; obtaining a target vehicle speed of the vehicle according to the transverse position error and the course angle error of the vehicle; acquiring an actual vehicle speed of the vehicle, and calculating a difference value between the actual vehicle speed and the target vehicle speed; adjusting the vehicle speed instruction according to the difference value, and controlling the vehicle to run according to the adjusted vehicle speed instruction; in the running process of the vehicle, obtaining the distance between the vehicle and a target parking point; and controlling the vehicle according to the distance between the actual position of the vehicle and the target parking point. According to the control method, longitudinal control over accurate position parking of the vehicle can beachieved, it is guaranteed that the vehicle runs normally under different working conditions, and the situation that the vehicle decelerates and even stops is avoided.

    本发明提供一种车辆及其车速控制方法和装置,所述方法包括以下步骤:获取车辆的横向位置误差和航向角误差;根据车辆的横向位置误差和航向角误差获取车辆的目标车速;获取车辆的实际车速,并计算实际车速与目标车速之间的差值;根据差值对车速指令进行调整,并控制车辆按照调整后的车速指令行驶;在车辆行驶过程中,获取车辆与目标停车点之间的距离;根据车辆的实际位置与目标停车点之间的距离对车辆进行控制。本发明的控制方法,能够实现车辆纵向控制精准位置停车,并且保证车辆在不同的工况下正常行驶,避免出现车辆减速甚至停车的情况。
