Abstract
In a steering angle control system including a feed-forward control for producing a desired vehicle motion variable and a feedback control for suppressing disturbances, a controller calculates a corrected steering angle from a detected steering angle and a premeasured characteristic of a steering system. The desired vehicle motion variable is calculated from a vehicle speed and the corrected steering angle. The feedback control is executed according to the difference between the desired and detected vehicle motion variables. Therefore, a driver can control a vehicle with a smooth control response in spite of a non-linear characteristic of the steering system.
