To provide an electric suspension device capable of achieving both of a high-level vibration cutoff performance in an upper spring member and a high-level grounding performance in a lower spring member according to a momentarily varying motion state of the vehicle 10.SOLUTION: An electric suspension device comprises: an electromagnetic actuator 13 for generating driving force associated with vibration damping of a vehicle body; an information acquisition part 43 for acquiring each of time series information on a stroke position of the electromagnetic actuator 13, and information on a stroke velocity SV and a stroke direction during reversion, and information on a stroke amount AS after the reversion; a damping force calculation part 45 for calculating target damping force on the basis of the information on the stroke speed SV; and a drive control part 49 for performing drive control of the electromagnetic actuator 13 using the target driving force based on the target damping force calculated by the damping force calculation part 45. The damping force calculation part 45 compensates the target damping force on the basis of the information on the stroke amount AS after the reverse acquired by the information acquisition part 43.SELECTED DRAWING: Figure 3
【課題】ばね上部材における振動遮断性能とばね下部材における接地性能とを、時々刻々と変動する車両１０の運動状態に応じて高水準で両立させる。【解決手段】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係る時系列情報、ストローク速度ＳＶ、並びに、ストローク方向に係る反転時の情報及び反転後におけるストローク量ＡＳの情報をそれぞれ取得する情報取得部４３と、ストローク速度ＳＶの情報に基づいて目標減衰力を算出する減衰力算出部４５と、減衰力算出部４５で算出した目標減衰力に基づく目標駆動力を用いて電磁アクチュエータ１３の駆動制御を行う駆動制御部４９と、を備える。減衰力算出部４５は、情報取得部４３で取得した反転後におけるストローク量ＡＳの情報に基づいて目標減衰力の補正を行う。【選択図】図３
