The invention provides a PWM (Pulse Width Modulation) torque control method, a motor controller and a readable storage medium. The method comprises the following steps: acquiring original rotating speed information of a motor under the action of PWM torque; filtering the original rotating speed information of the motor to obtain inherent frequency rotating speed fluctuation information of the whole vehicle; inhibition torque is determined according to the inherent frequency rotating speed fluctuation information of the whole vehicle; and taking a superposition result of the inhibition torque and the whole vehicle demand torque as a target input torque of a PWM torque strategy. According to the method, the fluctuation range of the whole vehicle can be effectively reduced under the condition that the PWM torque function of the whole vehicle is started to improve the efficiency of the electric drive system, and then the drivability of the whole vehicle can be effectively improved.

    本发明提供了一种PWM扭矩控制方法、电机控制器和可读存储介质,该方法包括:获取PWM扭矩作用下的电机原始转速信息;对电机原始转速信息进行滤波处理,以获取整车固有频率转速波动信息;根据整车固有频率转速波动信息,确定抑制扭矩;将抑制扭矩和整车需求扭矩的叠加结果作为PWM扭矩策略的目标输入扭矩。本发明可以使得整车在开启PWM扭矩功能以提高电驱系统效率的情况下,有效降低整车波动幅度,进而可以有效改善整车驾驶性。
