ABSTRACT:
An active suspension control system employs a strategy minimum fluid pressure in the working chamber of an inside suspension system is reached at greater lateral acceleration than that via which at which the maximum fluid pressure in the working chamber of an outside suspension system is reached. The system also takes a strategy for adjusting the fluid pressure in the working chambers of the inside and outside suspension system inversely proportional to each other while the lateral acceleration is maintained smaller than a predetermined pressure at which the maximum fluid pressure in the working chamber of the outside suspension system is reached. This assures driving stability and riding comfort by permitting vehicular rolling in response to a lateral acceleration greater that a given lateral acceleration criterion.
