Abstract
A vehicle suspension system includes a suspension unit comprising a hydraulic actuator of variable displacement connected to the chassis or body of the vehicle and a wheel and hub assembly of the vehicle and a control device for varying the displacement of the actuator in response to signals received from transducers on the vehicle to control the vehicle suspension. The suspension unit further comprises a displacement detector device to detect when the actuator displacement approaches a desired maximum/minimum value and a device to modify the velocity demand signal which operates in response to the control signal generated by the displacement detector device to bring the extension/contraction of the actuator gradually to a stop as the desired maximum/minimum value is reached.
