PROBLEM TO BE SOLVED: To provide an electromagnetic suspension device capable of inhibiting a vehicle from going into full-bump or full-rebound in an extreme driving situation of the vehicle.SOLUTION: The electromagnetic suspension device includes: an electromagnetic actuator 13 which is disposed side by side with a spring member provided between a body and a wheel of a vehicle 10 and which produces a driving force for damping operation and extending and contracting operation; an information acquisition unit 41 which acquires the stroke position of the electromagnetic actuator 13; and an ECU 15 which sets a target damping force and a target stretching force of the electromagnetic actuator 13 and controls a driving force of the electromagnetic actuator 13 by using a target driving force based on the set target damping force and target stretching force. When the stroke position is in an end region CT3 close to a stroke end, the ECU 15 corrects the target driving force such that the stroke position shifts from the end region CT3 toward a neutral region CT1.SELECTED DRAWING: Figure 3
【課題】車両の過酷な走行シーンにおいて、フルバンプ又はフルリバウンド状態に陥る事態を抑制可能な電磁サスペンション装置を得る。【解決手段】車両10の車体と車輪の間に備わるばね部材に並設され減衰動作及び伸縮動作に係る駆動力を発生させる電磁アクチュエータ13と、電磁アクチュエータ13のストローク位置を取得する情報取得部41と、電磁アクチュエータ13の目標減衰力及び目標伸縮力を設定すると共に、当該設定した目標減衰力及び目標伸縮力に基づく目標駆動力を用いて電磁アクチュエータ13の駆動力制御を行うECU15と、を備える。ECU15は、ストローク位置がストローク終端近傍の終端領域CT3に存する場合、ストローク位置を終端領域CT3から中立領域CT1へと向かわせるように目標駆動力の補正を行う。【選択図】図3
