Abstract
A steering torque sensor detects steering torque of a steering wheel. A steering angle sensor detects a steering angle of the steering wheel. An abnormality determining unit determines that a characteristic change is caused in the steering transmission system, when it is determined that the steering torque is smaller than or equal to a predetermined value and when the number of times when a difference between target vehicle behavior that is calculated from the steering angle and actual vehicle behavior is larger than or equal to a reference value is larger than or equal to a predetermined number of times during one steering.
