Abstract: A motor control apparatus and method for a vehicle. A motor includes windings respectively including coils. Inverters supply electric power to one of the windings to drive the motor. Controllers control the inverters to control the operation of the motor. The windings, the inverters and the controllers are set as a plurality of power supply lines respectively including a winding, an inverter and a controller. One of the power supply lines, in which at least one of the winding, the inverter or the controller has malfunctioned, is determined as having malfunctioned. Electric power that has been supplied via the power supply line determined as having malfunctioned is controlled to supplement power of another power supply line. Redundancy is obtained in the operation of a variety of motors provided in the vehicle, and the vehicle travels reliably.
