ABSTRACT:
A vehicle rear wheel steering control system includes a steering actuator for varying an actual rear wheel steer angle in accordance with a control signal, a steering input sensor, and a controller for producing the control signal in accordance with the steering input. The controller has a first functional section for determining a first desired rear wheel steer angle so as to obtain a flat characteristic of a yaw rate gain with respect to a steering frequency, a second functional section for determining a second desired rear wheel steer angle in accordance with a steering acceleration, and a third functional section for adding the second desired rear wheel steer angle to the first desired rear wheel steer angle.
