The invention discloses a vehicle, a motor rotating speed control method and device thereof and a storage medium. The motor rotating speed control method comprises the following steps: when the vehicle accelerates, obtaining a rotating speed gradient value of a motor and a target torque corresponding to an accelerator pedal of the vehicle; performing torque limitation on the target torque according to the rotating speed gradient value; and controlling the motor according to the limited target torque to prevent the motor from overspeed. Therefore, in the vehicle acceleration process, the target torque corresponding to the accelerator pedal of the vehicle is limited according to the rotating speed gradient value of the motor, so that a torque control strategy is optimized, the situation that the target torque is too large, and consequently the motor is overspeed is effectively prevented, the service life of a gearbox is prolonged, and the vehicle stability is ensured.

    本发明公开了一种车辆及其电机转速控制方法、装置和存储介质,其中,电机转速控制方法包括以下步骤:在车辆加速时,获取电机的转速梯度值和车辆的油门踏板对应的目标扭矩;根据转速梯度值对目标扭矩进行扭矩限制;根据限制后的目标扭矩对电机进行控制以防止电机超速。由此,在车辆加速过程中,根据电机的转速梯度值对车辆的油门踏板对应的目标扭矩进行限制,从而,优化扭矩控制策略,有效防止目标扭矩过大而导致电机超速,提高变速箱寿命,确保车辆稳定性。
