ABSTRACT:
An active suspension system derives a target pressure to adjust fluid pressure in a working chamber of an active cylinder on the basis of a difference between an actual height level and a desired or target vehicular height level. Pressure supply for the working chamber is so controlled as to establish the target height. The system detects a vehicular parking state in which the vehicle speed is zero and a road wheel is locked and limits the variation range of the fluid pressure in the working chamber at the target pressure.
