ペンシヨンシステム。[Claims for Utility Model Registration] A suspension unit that is interposed between the vehicle body and the wheels and can change the vehicle height by stroke using fluid pressure, and a pressure control valve that feedback-controls the fluid pressure output to the suspension unit. a detection means for detecting various vehicle body condition factors necessary for vehicle body attitude control; and an attitude control means for controlling the operation of the pressure control valve to form a predetermined vehicle body attitude based on a signal from the detection means. In the suspension system, the pressure control valve is provided with a follow-up prevention means for preventing the pressure control valve from following the feedback pressure, and a follow-up prevention control means is provided for activating the follow-up prevention means under predetermined conditions. A suspension system characterized by:
