Method for controlling the front wheel steer angle

Abstract

The method of the present invention improves the damping property of the yaw motion of the vehicle by feeding back a detected yaw rate value (r) in a dynamic sense for compensating the front wheel steer angle (8f) so as to increase the damping coefficient(Ç) of the yaw motion of the vehicle. By controlling the front wheel steer angle by accounting for not only the proportional term of the steering wheel input angle (8sw) but also the derivative term which is proportional to the steering wheel input angular speed, in the feed-forward control of the front wheel steer angle in relation with the steering operation by the driver, and by appropriately varying the control parameters of the yaw rate feed-back and the steering wheel input feed-forward, the yaw response of the vehicle can be made proportional to the steering wheel input, and the response delay in the yaw rate against the steering wheel input can be reduced to substantially zero.
