Abstract
In a vehicle suspension system, the fluid pressure type actuators provided between a vehicle body and wheels are so controlled that a ratio of the load to be born by the front wheels to the load to be born by the rear wheels determined based upon the rate of change of lateral acceleration is modified to be increased along with increase of vehicle speed, and in case of the four wheel steering, the roll stiffness in the rear wheels is decreased along with increase of vehicle speed, both for the purpose of improving the stability in steering at high vehicle speed while ensuring the high steerability at low vehicle speed. The roll stiffness in the rear wheels may also be modified to be higher in a transitional state than in a constant state in a turning.
