ABSTRACT:
In a vehicle suspension apparatus comprising communication control means for producing a disabling control signal for disabling the communicating solenoid valves when conditions are satisfied that the velocity detected by the velocity sensor exceeds a preset velocity and the steering angle detected by the steering sensor exceeds a preset steering angle and for producing an enabling control signal when the conditions are not satisfied, and roll control means for producing a control command signal for opening desired ones of the supply and exhaust control valves for a preset control time in order to supply a preset amount of fluid to contracted fluid spring chambers along a roll direction and for exhausting a preset amount of fluid from stretched fluid spring chambers when the conditions are satisfied, the preset velocity as one of the conditions determined by the communication control means is set to have a first value when the communicating solenoid valves are enabled and to have a second value larger than the first value when the communicating solenoid valves are disabled. With this apparatus, passengers experience uniform centrifugal force sensations when roll control is started and cancelled. Discomfort experienced by passengers during and after roll control is reduced to a minimum.
