Abstract: A suspension system for a vehicle, including (a) four displacement force generators (152) each configured to generate a displacement force forcing sprung and unsprung portions of the vehicle toward or away from each other; and (b) a control unit (200) configured to control the displacement force that is to be generated by each displacement force generator. The control unit is capable of executing a plurality of vibration damping controls concurrently with each other, by controlling the displacement force, so as to damp a composite vibration containing a plurality of different vehicle-body vibrations which are to be damped by the respective vibration damping controls. The control unit is configured to refrain from executing at least one of the vibration damping controls for damping one of the vehicle-body vibrations that is not required to be damped, in a low vibration intensity situation in which intensities of sprung-portion resonance-frequency vibration components in respective four sprung portions of the vehicle are lower than a threshold intensity degree.
