Abstract
A suspension system for a vehicle, including: an electromagnetic actuator configured to generate an actuator force and including a sprung-side unit supported by a sprung portion, an unsprung-side unit supported by an unsprung portion, a screw mechanism, and an electromagnetic motor; a connecting mechanism including a support spring for permitting one of the sprung-side and unsprung-side units to be floatingly supported as a floating unit by a unit-floatingly support portion that is one of the sprung and unsprung portions by which the floating unit is supported; and a controller including a sprung-vibration-damping control portion and a relative-vibration-damping control portion that is configured to execute a relative-vibration damping control for damping a vibration of the floating unit caused by the structure in which the floating unit is floatingly supported by the support spring.
