The invention provides a motor torque reversing control method, electronic equipment and a storage medium, and the method comprises the steps: obtaining the current wheel speed of a vehicle and the current actual rotating speed of a motor in response to a detected motor torque reversing request of the vehicle, and carrying out the back calculation of the current rotating speed of a motor end of the vehicle according to the current wheel speed; the current motor speed difference is obtained according to the current actual motor speed and the current motor end speed, whether the motor enters the torque reversing interval or not is judged according to the change condition of the current motor speed difference, if yes, the current torque restraining slope is determined to restrain the response torque of the motor, and accurate recognition of the torque reversing interval is achieved. And torque reversing accurate control is carried out when the motor enters the torque reversing interval, so that the transmission torque of the gear joint surface slowly completes turning control according to the inhibition slope, the problems of impact and abnormal sound are avoided, and the problem that the response speed of the motor torque is sacrificed due to the fact that slow gradient open-loop control is simply applied in the prior art is solved.

    本申请提供一种电机扭矩换向的控制方法、电子设备及存储介质,该方法响应于检测到车辆的电机扭矩换向请求,获取车辆的当前轮速以及当前电机实际转速,进而根据当前轮速反算车辆的当前电机端转速,根据当前电机实际转速以及当前电机端转速得到当前电机转速差,从而通过当前电机转速差的变化情况判断电机是否进入扭矩换向区间,若是,则确定当前扭矩抑制斜率以抑制电机的响应扭矩,实现了对扭矩换向区间的准确识别,以及在电机进入扭矩换向区间内的扭矩换向精准控制,以使齿轮接合面传递扭矩按照抑制斜率缓慢完成变向控制,避免产生冲击和异响问题,解决了现有技术中简单套用慢梯度开环控制导致的牺牲电机扭矩响应速度的问题。
