Abstract
An electrically powered suspension system includes: an electromagnetic actuator configured to generate a driving force related to vibration damping of the vehicle; an information acquisition unit configured to acquire information on a stroke velocity of the electromagnetic actuator; a target damping force calculation unit configured to calculate a target damping force based on the stroke velocity; a drive control unit configured to control driving of the electromagnetic actuator based on the target damping force; and a filter processing unit configured to perform a filtering process by applying a predetermined filtering characteristic to the stroke velocity. The filter processing unit has a plurality of filtering characteristics set in a second frequency region, which has a frequency higher than that of a first frequency region. The filter processing unit selectively applies, among the plurality of filtering characteristics, one filtering characteristic that is based on the stroke velocity to the stroke velocity.
