ABSTRACT:
A control system for a controlled vehicle having front and rear wheels has a steering wheel angle sensor, a vehicle speed sensor, a controller such as a microcomputer, and an actuating system for varying actual steering gear ratio and actual rear wheel steer angle to approach desired values under command of the controller. From input quantities, the controller determines a desired steering gear ratio by using equations of motion so that a desired steady state side slip angle, and a desired steady state yaw rate gain can be obtained, and further determines a desired rear wheel steer angle by using the equations of motion so that desired response characteristics can be obtained in a steady state or in both steady and transient states.
