The invention relates to a vehicle creep torque control method and device and a vehicle, and aims to solve the problem that the higher the vehicle speed is, the smaller the creep torque is during vehicle creep slope sliding in the prior art and improve the driving safety of the vehicle. The control method for the creep torque of the vehicle comprises the steps that the opening degree of a brake pedal of the vehicle is obtained; when the opening degree of the brake pedal is equal to zero, the rotating speed of a motor of the vehicle is determined; according to the motor rotating speed, the change rate of the creep torque corresponding to the motor rotating speed is determined, and the change rate represents that the size of the motor rotating speed is negatively related to the size of the creep torque; and the creep torque of the vehicle is controlled according to the change rate.

    本公开涉及一种车辆蠕行扭矩的控制方法、装置及车辆,以解决相关技术中车辆蠕行溜坡时存在的车速越高,蠕行扭矩越小的问题,提高车辆的驾驶安全性。本公开中的车辆蠕行扭矩的控制方法包括:获取车辆的制动踏板开度;当所述制动踏板开度等于零时,确定所述车辆的电机转速;根据所述电机转速,确定所述电机转速对应的蠕行扭矩的变化率,其中,所述变化率表征电机转速的大小与蠕行扭矩的大小负相关;按照所述变化率,控制所述车辆的蠕行扭矩。
