An apparatus for controlling an active suspension system for an automotive vehicle comprises hydraulic suspensions, control valves for independently controlling each of the suspensions and a controller for issuing a signal for controlling of opening/closing of the respective control valves. The apparatus includes a longitudinal g sensor for detecting a longitudinal acceleration of a vehicle body and a lateral g sensor for detecting a lateral acceleration of the vehicle. To calculate a control quantity relative to feeding of hydraulic fluid in and discharging of the hydraulic fluid from the respective suspensions required for suppressing pitching and rolling of the vehicle body, the apparatus further includes a control logic which in the controller. A control quantity derived from the circuits is added to another control quantity derived from a vertical g acceleration sensor and a vertical relative displacement sensor, and the resultant control quantity is delivered to the control valve for each suspension.
An apparatus for controlling an active suspension system for an automotive vehicle including a plurality of suspensions for supporting a vehicle body by pressure of hydraulic fluid, a plurality of control valves to feed the hydraulic fluid in and to discharge the hydraulic fluid from each suspension independently, vertical acceleration sensing means for sensing a vertical acceleration of the vehicle body, vertical relative displacement sensing means for sensing a vertical relative displacement between masses above and below each suspension, and first control quantity calculating means responsive to the vertical acceleration and the vertical relative displacement for calculating a first control quantity for the hydraulic fluid to be fed in and discharged from each suspension, comprising:
A component of an apparatus for controlling an active suspension system for an automotive vehicle including a plurality of suspensions for supporting a vehicle body by pressure of hydraulic fluid, a plurality of control valves to feed the hydraulic fluid in and to discharge the hydraulic fluid from each suspension independently, comprising:
