Vehicle suspension apparatus
A suspension apparatus is described comprising: suspension units mounted on respective wheel, each unit having a fluid spring chamber; fluid supply means for supplying a fluid to each fluid spring chamber through a fluid supply valve; communication paths each coupled between right and left fluid spring chambers and having a communicating control valve which is closed to achieve a roll control; field exhaust means for exhausting the fluid from each fluid spring chamber through a fluid exhaust valve; steering angle detecting means for detecting a steering wheel angle; velocity detecting means for detecting a vehicle velocity; control quantity determining means for determining a roll control quantity in accordance with the steering angle detected by the steering angle detecting means and the velocity detected by the velocity detecting means; and roll control means for controlling rolling of a vehcile body by opening/closing the fluid supply valves and the fluid exhaust valves in accordance with the roll control quantity determined by the control quantity determining means. In this way the fluid is supplied to the fluid spring chambers of the contracted suspension units with respect to a roll direction and the fluid is exhausted from the fluid spring chambers of the elongated suspension units when a vehicle changes a position thereof so as to control a change in the position of the vehicle.
