The invention discloses a control method and device of a motor controller, a storage medium and an automobile, the current phase current effective value of a motor is obtained, when the current phase current effective value is smaller than or equal to a phase current effective threshold value, it is determined that the motor controller is in a light load working condition, and the motor is intermittently and periodically controlled to output torque to drive the whole automobile to run. When the motor controller is in the light load working condition, the control strategy of intermittently and periodically controlling the motor output torque is adopted, and compared with continuous control over the motor output torque in a traditional scheme, power consumption in the whole vehicle running process is reduced, and the endurance mileage of the whole vehicle is increased.

    本发明公开了一种电机控制器的控制方法、装置、存储介质及汽车,获取电机的当前相电流有效值,在当前相电流有效值小于或等于相电流有效阈值时,确定电机控制器处于轻载工况,并间断性周期性的控制电机输出扭矩驱动整车行驶。本发明在电机控制器处于轻载工况时,采用间断性周期性的控制电机输出扭矩的控制策略,相对于传统方案中持续性的控制电机输出扭矩而言,降低了整车行驶过程中的功耗,提高了整车的续航里程。
