Abstract
The present invention relates to a system for determining whether to inhibit lowering of the ride height of a vehicle when the vehicle speed exceeds a speed threshold value. The system includes a processor having an input configured to receive ride attribute data from at least one on-board vehicle ride attribute sensor, the ride attribute data being indicative of the roughness of the surface over which the vehicle is travelling, and a data memory configured to store at least one predetermined ride attribute threshold value for the or each ride attribute sensor. The processor is configured to calculate a ride attribute parameter in dependence on the received ride attribute data for the or each ride attribute sensor. The processor is also configured to compare the or each calculated ride attribute parameter with the corresponding at least one predetermined ride attribute threshold value to determine whether the vehicle is travelling on a smooth surface or a rough surface, and to inhibit lowering of the ride height when it is determined that the vehicle is travelling on a rough surface.
