Provided is an electric suspension device capable of exhibiting a comfortable ride feeling accompanying a person-vehicle integration feeling even during braking in a sports traveling scenario. An electric suspension device is provided with: an electromagnetic actuator that is provided between a vehicle body and wheels of a vehicle and generates a load for damping vibration of the vehicle body; an information acquisition unit that acquires information on a sprung state quantity and a traveling road surface state of the vehicle; a target load calculation unit that calculates a first target load relating to ceiling control on the basis of the sprung state quantity, and a second target load relating to predictive control on the basis of the traveling road surface state; and a load control unit that controls the load of the electromagnetic actuator. The target load calculation unit further calculates a third target load relating to pitch generation control on the basis of the target pitch angle, and performs calculation of a combined target load in which the first and second target loads and the third target load are combined. The load control unit performs load control of the electromagnetic actuator using the combined target load.

    提供一种即使在运动行驶情景下的制动时也能够展现伴随着人车一体感的舒适乘坐感的电动悬架装置。电动悬架装置具备:电磁致动器,其设在车辆的车身与车轮之间,产生用于使车身的振动衰减的负荷;信息获取部,其获取车辆的簧上状态量及行驶路面状态的信息;目标负荷运算部,其计算出基于簧上状态量的涉及天棚控制的第1目标负荷、以及基于行驶路面状态的涉及预见控制的第2目标负荷;和负荷控制部,其进行电磁致动器的负荷控制。目标负荷运算部进一步计算出基于目标俯仰角的涉及俯仰生成控制的第3目标负荷,并且进行将第1及第2目标负荷和第3目标负荷合并的合并目标负荷的运算。负荷控制部使用合并目标负荷进行电磁致动器的负荷控制。
