Abstract

A vehicle suspension control system comprises an actuator device for connection between a sprung mass of a vehicle and unsprung masses of the vehicle. A suspension system further comprises a device for determining forces acting between the sprung mass and the unsprung masses and for producing signals proportional to said forces, the device for determining forces comprising a first sensor device operable to produce a first set of signals comprising signals indicative of the loads in load paths between the unsprung masses and the sprung mass and a second sensor device operable to produce a second set of signals which includes signals indicative of the lateral acceleration of the vehicle, the longitudinal acceleration of the vehicle, and the yaw rate of the vehicle; a device for processing the second set of signals to produce steady state force signals indicative of steady state input loads on the vehicle including loads arising from cornering and acceleration/deceleration of the vehicle and loads carried by the vehicle; a device for combining the steady state force signals with the first set of signals to produce dynamic force signals indicative of dynamic inputs to the vehicle, the …
