Abstract
Acceleration detecting sensor (60) is provided in a sprung structure (50), while a vibration model comprising the sprung mass of a vehicle, the spring, and the shock absorber is previously stored in control unit (58). The deviation of the detected acceleration from the estimated vertical acceleration of the sprung structure is computed by a control unit (58) and then amplified. The vertical acceleration of the sprung structure and the relative velocity between sprung and unsprung structures are estimated by a control unit (58) according to the amplified deviation and the vibration model. The stored vibration model has one degree of freedom and a simple structure.
