Abstract

A vehicle suspension incorporates suspension units (46 - 48) associated with respective vehicle wheels and selectively controllable to vary the ride height of the vehicle, vehicle speed sensing means, height sensing means responsive to departure of the ride height from a predetermined height datum which is a function of the vehicle speed and to provide a signal related thereto to control movement of at least one suspension unit thereby to tend to move at least a part of the vehicle to said predetermined height datum and timer means whereby the movement of a suspension unit in response to a signal from a height sensor is inhibited until a signal of at least a predetermined magnitude has persisted for at least a prescribed part of a prescribed period of time. <IMAGE>
