To obtain an electromagnetic suspension device which can maintain good riding comfort.SOLUTION: An electromagnetic suspension device comprises: an electromagnetic actuator 13 which is located in parallel to a spring member which is provided between a vehicle body and a wheel of a vehicle 10, and generates drive power concerning vibration damping of the vehicle body; an information acquisition part 51 which acquires time series information relating to a stroke position of the electromagnetic actuator 13 via a high-pass filter 71; and an ECU 15 which calculates target drive power of the electromagnetic actuator 13, and performs drive power control of the electromagnetic actuator by use of the calculated target drive power. In the case that a stroke position, which is based on time series information in which low frequency components after high-pass filter processing (steady-state deviation) are eliminated, exists in a neutral area CT1 including a neutral position, the ECU 15 so corrects the target drive power as to weaken a spring force concerning the spring member compared to the case that the stroke position exists in a non-neutral area CT2, CT3.SELECTED DRAWING: Figure 6

    【課題】良好な乗り心地を維持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、車体の振動減衰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のストローク位置に関する時系列情報を、ハイパスフィルタ71を介して取得する情報取得部51と、電磁アクチュエータ13の目標駆動力を算出すると共に、当該算出した目標駆動力を用いて電磁アクチュエータの駆動力制御を行うECU15と、を備える。ECU15は、ハイパスフィルタ処理後の低周波成分(定常偏差)が除去された時系列情報に基づくストローク位置が、中立位置を含む中立領域CT1に存する場合、ストローク位置が非中立領域CT2,CT3に存する場合に比べてばね部材に係るばね力を弱めるように目標駆動力の補正を行う。【選択図】図6
