Abstract:
1. A vehicle suspension for controlling motion of a sprung and unsprung mass comprising: a force source which is capable of applying a force in response to a control signal and without a physical stimulus, the force source coupling a vehicle unsprung mass and a vehicle sprung mass: a sensor for detecting vertical motion of the sprung mass or a quantity from which vertical motion of the sprung mass can be derived; an unsprung mass sensor for detecting vertical motion of the unsprung mass or a quantity from which vertical motion of the unsprung mass can be derived; and control circuitry; responsive to the sprung mass sensor for determining a force to reduce the vertical motion of the sprung mass in a first frequency range; and responsive to the unsprung mass sensor for determining a force to reduce the vertical motion of the unsprung mass in a second frequency range; wherein the first frequency range includes frequencies above and below the second frequency range and wherein the first frequency range does not include the second frequency range.
