Included are an electromagnetic actuator which generates a drive force for damping vibration of a vehicle body; an information acquirer which acquires time-series information about a stroke position of, and information about a stroke velocity of, the electromagnetic actuator, as well as information about reverse of a stroke direction and information about a stroke amount after the reverse; a damping force calculator which calculates a target damping force based on the information about the stroke velocity; and a drive controller which controls drive of the electromagnetic actuator using a target drive force based on the target damping force calculated by the damping force calculator. The damping force calculator corrects the target drive force based on the information about the stroke amount after the reverse acquired by the information acquirer.
