Abstract
A four wheel steer vehicle is provided with a suspension control system for controlling at least one suspension characteristic, one or more sensors for sensing a change in suspension characteristics by sensing a condition of the suspension control system, and a controlling element for varying a ratio of a rear wheel steer angle to a steering wheel angle in accordance with the suspension characteristic. Examples of the suspension characteristics are spring constants of front and rear suspensions, heights of the front and rear suspensions, damping forces of the front and rear suspensions, roll stiffnesses of the front and rear suspensions, and front wheel alignment angles such as camber and toe-in.
