A suspension system for a vehicle, including: an electromagnetic actuator including: a sprung-side unit connected to a sprung portion; an unsprung-side unit connected to an unsprung portion; and an electromagnetic motor, the actuator being configured to generate an actuator force; a connecting mechanism including a support spring; and a controller which includes a target-actuator-force determining portion configured to determine, according to a prescribed control rule, a target actuator force, wherein the determining portion is configured to determine the target actuator force on the basis of: (a) a required acting force that is a force required to act between the sprung portion and the unsprung portion by the actuator and the connecting mechanism; and (b) an inertial force of one of the sprung-side unit and the unsprung-side unit with respect to a displacement of one of the sprung portion and the unsprung portion, while utilizing: a first transfer function by which is outputted an amount of a displacement of the one of the sprung-side unit and the unsprung-side unit relative to the one of the sprung portion and the unsprung portion when the actuator force is inputted; and a second transfer function by which is outputted an actual acting force which actually acts between the sprung portion and the unsprung portion when the amount of the displacement is inputted.
