Abstract:
An electromagnetic suspension device includes: an electromagnetic actuator which is disposed side by side with a spring member provided between a body and a wheel of a vehicle and which produces a driving force for damping operation and extending and contracting operation; an information acquisition unit which acquires the stroke position of the electromagnetic actuator; and an ECU which sets a target damping force and a target stretching force and controls a driving force of the electromagnetic actuator by using a target driving force based on the set target damping force and target stretching force. When the stroke position acquired by the information acquisition unit is in an end region close to a stroke end, the ECU corrects the target driving force such that the stroke position shifts from the end region toward a neutral region.
