Abstract
Included are an electromagnetic actuator which includes an electric motor configured to generate drive forces for a damping operation and a telescopic operation; an information acquirer which acquires a stroke velocity of the electromagnetic actuator; a drive force arithmetic part which includes a damping force calculator configured to calculate a target damping force and a telescopic force calculator configured to calculate a target telescopic force, and which obtains a target drive force based on the target damping force and the target telescopic force; and a drive controller which controls drive of the electric motor using the target drive force. The drive force arithmetic part includes an adjuster which performs an adjustment to reduce a telescopic control amount for the target telescopic force based on the stroke velocity acquired by the information acquirer.
