Abstract
An active suspension system of a vehicle has a feed back control system for controlling four suspensions for the four wheels to maintain a reference vehicle height responsive to detected vertical relative displacements between the wheels and the vehicle body at said suspensions, and a feed forward control system for controlling the suspension to maintain an intended rolling of the vehicle responsive to detected lateral acceleration. There is further provided a circuit for changing the reference vehicle height which is responsive to the absolute value of the detected lateral acceleration, and operates to reduce the reference vehicle height with increase of the absolute value so that the vehicle body is lowered while the rolling is maintained whereby a better driver's sensation during a vehicle turn is obtained and the capability of turning of the vehicle is improved.
