ABSTRACT:
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.
