2053870 9013449 PCTABS00002 The invention provides a land vehicle suspension control system comprising means for measuring forces acting between the sprung mass of the vehicle (the body of the vehicle) and unsprung masses (wheel and hub assemblies) connected thereto, means for producing signals proportional to the resulting measured force values, means for determining from the signals the values of the forces required to be applied between the unsprung masses and the sprung mass to minimise force changes experienced by the sprung mass, means for determining the values of demanded relative velocities required between the sprung mass and the unsprung masses to satisfy the force requirements and means for applying the required forces between the unsprung masses and the sprung mass of the vehicle in proportion to the values of the relative velocities required between the sprung mass and the unsprung masses. The invention provides an active suspension control system, the outputs of which correspond to velocities required of the actuators of the system rather than the displacements required of the actuators. The invention provides means by which the actuators can be effectively controlled by velocity demands, with necessary feedback to ensure accurate control.
