Abstract
A suspension assembly for a motor vehicle includes a wheel assembly attached to the frame of a motor vehicle for movement in response to uneven roadway surfaces. A first inductive coil attached to the frame is mounted along an axis, and a second inductive coil is mounted co-axially with the first inductive coil and for movement with the wheel assembly. The inductive coils are movable relative to one another along the axis. An electromagnetic force generated by the inductive coils provides spring and dampening forces for the motor vehicle. Further, variation in the inductance between the coils is measurement to determine the relative position between the coils in order to monitor motor vehicle ride height.
