To provide an electromagnetic suspension apparatus capable of quickly reducing the influence of a mechanical frictional force generated in each part of an electromagnetic actuator.SOLUTION: An electromagnetic suspension apparatus comprises: an electromagnetic actuator 13 that is provided in parallel with a spring member provided between the vehicle body and the wheel of a vehicle 10 and generates a driving force related to damping operation and expansion/contraction operation; an information acquisition unit 51 that acquires vehicle state information including the stroke speed of the electromagnetic actuator 13; an equivalent frictional force calculation unit 53 that calculates the equivalent frictional force of the electromagnetic actuator 13 on the basis of the vehicle state information; and an ECU 15 that calculates the target driving force of the electromagnetic actuator 13 and uses the calculated target driving force to control the driving force of the electromagnetic actuator 13. The ECU 15 corrects the target driving force on the basis of the equivalent frictional force calculated by the equivalent frictional force calculation unit 53.SELECTED DRAWING: Figure 3

    【課題】電磁アクチュエータの各部で生じる機械的な摩擦力の影響を速やかに減殺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のストローク速度を含む車両状態情報を取得する情報取得部51と、車両状態情報に基づいて電磁アクチュエータ13の等価摩擦力を算出する等価摩擦力算出部53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、該算出した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、等価摩擦力算出部53で算出した等価摩擦力に基づいて目標駆動力の補正を行う。【選択図】図3
