    摘要： The suspension system comprises support means (7) installed between a wheel (1) and the vehicle body (5) exerting suspension force which can be changed irrespective of relative displacement between the wheel and the vehicle body. According to low frequency components of a parameter which represents changing condition of the relative displacement, the support means is controlled to exert a suspension force in such a way that the relative displacement can be suppressed. Such parameters include the relative displacement and the rate of the change thereof.
    Suspension characteristics can be maintained to maintain riding qualities and rolling and pitching properties in a preferable condition throughout all running conditions.

    摘要： A vehicle suspension system (1) including a hydraulic cylinder (2) and a gas spring (8) having a gas chamber (16) and a hydraulic chamber (18) which is connected with the hydraulic cylinder (2). The hydraulic cylinder is located between the vehicle body and the wheel to support the body on the wheels. A control valve (48) is provided for controlling the supply of hydraulic pressure to the cylinder in accordance with a signal from a control unit (60). The control unit receives a detection signal from a detector which detects the pressure in the cylinder and produces a control signal in accordance with a transfer function H(s) = R x S/(1 + R x S).
