The invention discloses a motor rotating speed control method for a vehicle. The method comprises the steps that the current gear of the vehicle, the real-time rotating speed of a motor and the request torque of the vehicle are obtained; performing data conversion processing on the real-time rotating speed so as to convert the real-time rotating speed into limiting torque; selecting one of the request torque and the limited torque as a target torque according to the current gear of the vehicle; the target torque is converted into the output rotating speed of the motor, so that the output rotating speed is applied to control the motor; and updating the real-time rotating speed according to the output rotating speed. The invention further discloses a motor rotating speed control device of the vehicle, motor rotating speed control equipment of the vehicle and a computer readable storage medium. By adopting the embodiment of the invention, the rotation speed of the motor can be limited through closed-loop control so as to realize the anti-slip function of the vehicle, complicated control logic is not needed, the state switching of the rotation speed does not exist, and the method has the characteristics of simplicity and strong robustness.

    本发明公开了一种车辆的电机转速控制方法,包括:获取车辆当前所处档位、电机的实时转速和车辆的请求扭矩;对所述实时转速进行数据转换处理,以将所述实时转速转换成限制扭矩;根据所述车辆当前所处档位从所述请求扭矩和所述限制扭矩中选择一个作为目标扭矩;将所述目标扭矩转换成所述电机的输出转速,以应用所述输出转速对所述电机进行控制;根据所述输出转速对所述实时转速进行更新。本发明还公开一种车辆的电机转速控制装置、一种车辆的电机转速控制设备和一种计算机可读存储介质。采用本发明实施例,能够通过闭环控制对电机转速进行限制以实现车辆的防溜坡功能,无需复杂的控制逻辑且不存在转速的状态切换,具有简易且鲁棒性强的特点。
