The invention provides a motor control method, a vehicle control unit, an electric vehicle and a medium, and relates to the technical field of electric vehicles. The method responds to a motor resolver signal fault message sent by a motor controller, outputs a whole vehicle fault alarm instruction to a vehicle instrument panel, and controls the whole vehicle to lower high voltage; in response to the input emergency switch starting signal, a braking depth signal and an electric switch opening degree signal of the vehicle are obtained; determining a corresponding braking state signal and a motor torque signal according to the braking depth signal and the switch opening signal; and the braking state signal and the motor torque signal are sent to a motor controller, so that the motor controller determines the rotating speed of a motor according to the braking state signal and the motor torque signal, and a driving motor of the vehicle is controlled according to the rotating speed of the motor. According to the method, the motor can be accurately controlled to run when the motor resolver signal is abnormal, so that the vehicle is controlled to run normally.
