ABSTRACT:
A suspension pressure control system applies a pressure which is proportional to a current level supplied to a solenoid of a pressure control valve to a shock absorber associated with a suspension from the valve through a cut valve, which cuts off a fluid path from the pressure control valve to the shock absorber when a line pressure is below a predetermined value and communicates the fluid path when the line pressure exceeds the predetermined value. An electronic controller controls the current level to maintain an attitude of a vehicle substantially constant in spite of any change of longitudinal and lateral acceleration, which are detected by acceleration sensors. In order to prevent an abrupt or abnormal change of the pressure of the shock absorber at an initiation of the pressure control of the controller when the vehicle is parking on a slope, the controller initiates the pressure control before the cut valve communicates the fluid path.
