Equalizing phase lags of yaw rate and lateral acceleration while also minimizing both phase lag values in vehicle transient response has been found to improve vehicle maneuverability at low to high road speeds. To realize these operating characteristics, “SS 4WS” (Speed-Sensing Four-wheel Steering system) has been developed as a system to control optimally the steering ratio of rear to front wheels. Various tests have verified the effectiveness of this system.
