Abstract: A vehicle suspension control for a vehicle having each wheel (11) supported from the chassis of the vehicle trough a fluid operated extension element (13, 19), the control comprising a controller (27), a plurality of sensors (21, 23, 25, 27, 30, 32), a fluid flow controller (29), a first sensor (21) adapted to sense the relative position between the wheel (11) and the chassis and provide a first output to the controller, a second sensor (23) adapted to sense the pressure of the fluid in each extension element (13, 19) and provide a second output to the controller (27) adapted to receive the output from each of the sensors (21, 23) at each wheel, process the outputs and provide a wheel output to the fluid flow controller (29) for each wheel, the force applied by the extension elements (13, 19) between the chassis and wheels will maintain the attitude of the chassis substantially constant relative to a plane.
