The invention relates to a motor vector control method. The method comprises the following steps: determining a direct-current fundamental component Is of a current to be applied to a motor based on a power loss requirement # imgabs0 # and a set frequency Foff; generating an AC component ISa by means of an AC signal generator; superposing the AC component ISa to the DC fundamental component IS to determine an AC-DC synthesis quantity of a current to be applied to the motor; determining the given torque # imgabs 1 # rotor temperature Trotor of the motor, the rotating speed w of the motor and the direct current side voltage Udc of a motor inverter; determining a direct-current control component in the dq-axis current of the motor; determining an alternating current control component in the dq-axis current of the motor; and controlling the operation of the motor based on the DC control component and the AC control component, respectively. The invention further relates to a method for heating a battery pack of a vehicle during driving by means of the vector control method, and to a motor inverter.
