ABSTRACT:
An actively controlled suspension system introduces two-way mode operation in controlling suspension. A suspension control system operates in a normal mode for controlling fluid pressure in a hydraulic cylinder disposed between a vehicle body and a suspension member is adjusted depending upon the vehicle driving conditions in order to suppress vehicular attitude change, and a power OFF transition mode for controlling the fluid pressure toward a preset neutral pressure. The hydraulic circuit is constructed to maintain the pressure in the working chamber of the hydraulic cylinder at the neutral pressure while power is not supplied to control system.
