The invention provides an electric vehicle motor torque control method and device, electronic equipment and a storage medium, and the electric vehicle motor torque control method comprises the steps that operation parameters of a motor are obtained, and the operation parameters of the motor comprise target motor torque; determining a motor torque limit value based on the target motor torque; and controlling the output torque of the motor based on the motor torque limit value. The output torque of the motor can be controlled according to the target motor torque, so that the situation that the output torque of the motor is too small or is reverse torque is avoided, transmission gaps are avoided, secondary collision of a motor gear is finally avoided, the service life loss of the motor gear is reduced, and the riding smoothness is improved.

    本申请提供一种电动汽车电机扭矩控制方法、装置、电子设备和存储介质,其中,电动汽车电机扭矩控制方法包括:获取电机的运行参数,其中,所述电机的运行参数包括目标电机扭矩;基于所述目标电机扭矩确定电机力矩限制值;基于所述电机力矩限制值控制所述电机的输出扭矩。本申请能够根据目标电机力矩控制所述电机的输出扭矩,从而避免电机的输出扭矩过小或为反向扭矩,从而避免产生传动间隙,最终避免电机齿轮二次撞,降低电机齿轮的寿命损耗,以及提高驾乘平顺性。
