Abstract
An apparatus for controlling steering of wheels of a vehicle comprises a control means, a driving means, and an actuator means. The control means comprises a feed forward signal operating means, a feed back signal operating means for generating signals for variables representing vehicle behaviors and output from a vehicle behavior sensor, and a control signal operating means for calculating a difference or sum of the signals output from the feed forwad and feedback signal operating means. The feed forward signal operating means comprises a steering angle signal circuit, a steering angular velocity signal operating circuit, a steering angle signal operating circuit having a first coefficient circuit for multiplying a steering angle signal with a coefficient, and an adder for adding the outputs from the steering angle signal circuit, the steering angle signal operating circuit, and the steering angular velocity operating circuit. A behavior correction capacity against a side wind or disturbance is very high, and a steering system can be controlled to shorten the response time for changes in vehicle behaviors with respect to a steering input, thereby providing optimal steering.
