Abstract:
PCT No. PCT/GB90/00628 Sec. 371 Date Dec. 13, 1991 Sec. 102(e) Date Dec. 13, 1991 PCT Filed Apr. 24, 1990 PCT Pub. No. WO90/12700 PCT Pub. Date Nov. 1, 1990.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.
