摘要： A suspension control system employs an acceleration sensor for monitoring an inertial force affecting for vehicular attitude. A control system coacting therewith includes a mechanism for lowering the level of an output signal of the acceleration sensor to eliminate therefrom any error corresponding a resonance frequency of the acceleration sensor for obtaining higher accuracy inertially indicative data.

摘要： A suspension control system performs vehicular attitude regulating operation by adjusting damping characteristics at respective of suspension systems. For controlling damping characteristics, a suspension control command value is derived on the basis of an acceleration exerted on the vehicular body, which acceleration influences vehicular attitude. The suspension control command value is variable depending upon the magnitude of the vehicular attitude influencing acceleration. Variation rate of the suspension control command value versus variation of the vehicular attitude influencing acceleration is variable in such a manner that increasing rate of the suspension control command value decreases according to increasing of the acceleration.

摘要： A suspension control system includes a plurality of suspension systems respectively disposed between a vehicular body and each road wheel thereof, the suspension systems having variable damping characteristics. Each suspension system is associated with means for adjusting damping characteristics according to a suspension control command. Each suspension control system also includes a sensor means for monitoring an inertia force exerted on the vehicular body, which inertia force affects for vehicular attitude to cause a vehicular attitude change. A control unit receives the output of the sensor means and derives a suspension control command for regulating vehicular height and vehicular attitude. The control unit is designed to detect a predetermined particular vehicle driving condition on the basis of the sensor output for deriving the suspension control command for adjusting vehicular height to a lower level than a normal height level.

摘要： An active suspension system includes vertical acceleration sensors provided at positions where suspension systems associated with respective vehicular wheels are provided. A control unit receives vertical acceleration data of the respective suspension systems for processing the received data for deriving control command values representative of required damping magnitudes at the respective suspension systems. For this, the control unit derives angular velocity of vehicular attitude change. The control command value is thus derived on the basis of the vehicular attitude change and angular velocity.

摘要： An active suspension system employs a vertical acceleration sensor for monitoring vertical acceleration exerted on the vehicular body at an orientation where a suspension system is provided, to produce a vertical acceleration indicative signal. The system derives a vertical displacement speed on the basis of the vertical acceleration indicative signal. A suspension control command for stabilizing vertical vibration is thus derived on the basis of the vertical motion speed and a given gain. In order to facilitate satisfactorily high cornering stability, the system varies the gain for deriving the suspension control command depending upon a lateral acceleration exerted on the vehicular body.
