Abstract
An active suspension of a motor vehicle is controlled by a system and a method which comprise combining a controller and an actual flow quantity estimation circuit for estimating by logic operation the flow quantity of the fluid actually flowing through each control valve of the suspension with respect to a total desired flow quantity, and calculating the difference between the actual flow quantity value thus estimated and the desired flow quantity, thereby correcting the desired flow quantity. A command signals is generated and transmitted in accordance with the desired flow quantity thus corrected for operating the control valve to undergo opening/closing operation.
