The invention relates to a motor control method for a vehicle. The method includes: determining that a motor control unit (MCU) malfunctions; monitoring an output alternating current frequency of an electric motor; and controlling, based on the output alternating current frequency, the electric motor to switch between an active short circuit state and a safety pulse off state. The invention further relates to a motor control circuit for a vehicle, a motor drive system, and a vehicle.
