The invention discloses a vehicle sliding control method, a vehicle sliding control device and a vehicle, and the vehicle sliding control method comprises the following steps: the method enters a vehicle sliding control mode, and a slope parking preset torque of a driving motor is obtained; the actual working torque of the driving motor is controlled according to the slope parking preset torque; a rotating speed absolute value of the driving motor is acquired; and if the absolute value of the rotating speed is larger than a first rotating speed threshold value, the actual working torque of the driving motor is adjusted and controlled at 0 rotating speed, and the 0 rotating speed adjustment means that the rotating speed of the driving motor is controlled to tend to 0 through a PI controller, and torque output is conducted. According to the sliding control method of the vehicle, the output torque of the driving motor is controlled according to the standing wave preset torque, so that initial slope parking is rapidly achieved, the sliding distance in the parking process is reduced, if vehicle parking is not achieved after initial slope parking, vehicle parking is achieved through zero-rotation-speed adjustment, it is ensured that vehicle parking is achieved, and the stability in the parking process is improved.

    本发明公开了一种车辆的溜车控制方法、车辆的溜车控制装置和车辆,所述车辆的溜车控制方法包括:进入溜车控制模式,获取驱动电机的驻坡预设扭矩;根据驻坡预设扭矩控制驱动电机的实际工作扭矩;获取驱动电机的转速绝对值;如果所述转速绝对值大于第一转速阈值,则以0转速调节控制所述驱动电机的实际工作扭矩,其中所述0转速调节是指:通过PI控制器控制驱动电机转速趋于0并进行扭矩输出。本发明实施例的车辆的溜车控制方法,根据驻波预设扭矩控制驱动电机输出扭矩,以快速实现初步坡道驻车,降低驻车过程中的溜车距离,若在初步坡道驻车后未实现车辆驻车,则通过0转速调节以实现车辆驻车,以确保实现车辆驻车,并提高了驻车过程中的稳定性。
