摘要： In a hydraulic active suspension system, a plurality of actuators (1FR,1FL,1RR,1RL) having working fluid chambers (2FR,2FL,2RR,2RL) are provided corresponding to vehicle wheels. Each actuator is adapted to increase and decrease vehicle height in response to the pressure within its working chamber, which is controlled by a pressure control device. Vehicle speed and lateral acceleration are detected by corresponding sensors (234,238). A control device is further provided for controlling the pressure control device by compensating values determined based upon the lateral acceleration detected. The control device is adapted to reduce the compensating values in magnitude when the vehicle speed is lower than a predeterminate value under which the lateral acceleration sensor sometimes detects a flase lateral acceleration, thereby reduce the possibility that the vehicle body may generate an unpleasant roll due to the erroneous control on the pressures within the working fluid chambers based upon a flase lateral acceleration.

摘要： 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.
