Abstract:
When a partial malfunction is detected, a sensor malfunction determination unit changes a control mode from a first control mode to a second control mode. When the control mode is changed from the first control mode to the second control mode, a steered system motor is rotated in a direction corresponding to a rotation direction of a steering wheel immediately before the partial malfunction occurs in the angle sensor. When the absolute value of a steering angular velocity of the steering wheel exceeds a threshold, it is determined that a driver has operated the steering wheel in a direction opposite to a current steered direction, and the rotation direction of the steered system motor is reversed.
