Abstract

The invention relates to an active suspension system for controlling the suspension of a wheeled land vehicle, which comprises an actuator (31) of variable length in parallel with a spring (34), connected between the body or chassis of a vehicle and a wheel and hub assembly (40) of such. The extension/contraction of the actuator is controlled by a control unit (60) in response to parameters measured by various sensors (61, 64, 65, 66 and 62). The control unit (60) also makes allowance for loads on the vehicle not measured by the sensors, so that accurate control of the suspension system is achieved.
