Patent ID: 7891673

Claim:
A suspension control system for a vehicle having a frame and a wheel, the suspension control system comprising: a liquid spring operably interposed between the frame and the wheel using a compressible liquid to generate spring forces in response to relative displacement between the frame and the wheel; a second volume of compressible liquid housed in a second chamber, the second volume removably connected to the liquid spring by a fluid passage; a valve coupled to the fluid passage, the valve selectively operable to place the second volume in communication with the liquid spring; a turning motion sensor; and a controller electrically coupled to the turning motion sensor and the valve, the controller receiving signals from the turning motion sensor and emitting a control signal to control the valve; wherein the controller is configured to alter the control signal to modulate the valve to adjust at least one of the group consisting of a pressure, a volume, and a rate of flow of compressible liquid in each of the liquid springs to vary seamlessly in between minimum and maximum attainable values to alter both the stiffness and the damping of the liquid spring.
