Provided is an electric suspension device capable of appropriately responding to vibrations or the like applied to a vehicle. An electric suspension device (11) is provided with: a return prevention circuit (190) that operates in either a return prevention mode in which current from a power storage unit (172) to a power supply unit (180) is prevented, or a return permission mode in which current from the power storage unit (172) to the power supply unit (180) is permitted; and a discharge control unit (124) that determines whether or not the electric motor (31) is in regenerative operation, sets the operation mode of the return prevention circuit (190) to a return prevention mode when the determination result is positive, and sets the operation mode of the return prevention circuit (190) to a return permission mode when the determination result is negative.

    本发明提供能够适当响应施加于车辆的振动等的电动悬架装置。电动悬架装置(11)包括:返回防止电路(190),其以防止从电力蓄积部(172)朝向电源部(180)的电流的返回防止模式、和容许从所述电力蓄积部(172)朝向所述电源部(180)的电流的返回容许模式中的任一种动作模式动作;以及放电控制部(124),其判定所述电动马达(31)是否为再生运转中,在判定结果为肯定的情况下,将所述返回防止电路(190)的动作模式设定为返回防止模式,在所述判定结果为否定的情况下,将所述返回防止电路(190)的动作模式设定为返回容许模式。
