Abstract
Motor-generators are incorporated in front wheels and drive the front wheels, respectively. An ECU determines whether or not a steering apparatus including a steering actuator, a tie rod and a steering angle sensor has failed, based on an operation angle of a steering wheel from a steering wheel angle sensor and a steering angle of the front wheels from the steering angle sensor. When the ECU determines that the steering apparatus has failed, the ECU provides torque difference for a torque instruction for the motor-generators in accordance with the operation angle of the steering wheel.
