Abstract
An active vehicle suspension system has a suspension device with a variable offset gas spring and a double acting hydraulic actuator acting in parallel. Load changes experienced by the device are sensed electrically, or electrically and hydraulically, so as to effect appropriate response of the device by adjustment of the actuator pending change of the offset of the gas spring, so as to reduce energy requirements.
