Abstract
A vehicle suspension system () includes an electromagnetic damper () provided with a sprung member () and an unsprung member () to apply a drive force and a damping force between the sprung member and the unsprung member, and a control unit () for controlling the electromagnetic damper. A target load for the electromagnetic damper is determined based on the unsprung member demand load that attenuates a vertical vibration of the unsprung member, and the sprung member demand load that restrains a vertical displacement of the sprung member. An absolute value of the sprung member demand load is reduced when a sprung member frequency is in an unsprung member resonance frequency range.
