摘要： 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.

摘要： A vehicle suspension system comprises suspension units (2) with double acting hydraulic actuators (12) for carrying the road wheels (4). Signals from transducers sensing actuator load and actuator piston position (14,15) are used in a control system (5) to generate signals representing forces corresponding to heave, pitch, roll and warp modes of vehicle movement and control signals are generated for supply to servo-valves (18) associated with the actuators to obtain desired vehicle attitude. The control signals can be modified by signals representing vehicle speed and lateral and longitudinal acceleration and under selective control of the driver.
