Provided is an electric suspension device which, even when a large input is generated in a damper while a vehicle is traveling, is capable of buffering the large input and maintaining a comfortable ride feeling. An electric suspension device is provided with: an electromagnetic actuator for generating a load for damping vibration of the vehicle body of a vehicle; an information acquisition unit (41) that acquires information on the sprung state quantity and the 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 calculates a combined target load in which the first target load and the second target load are combined with a third target load relating to virtual spring force control on the basis of the stroke position. The load control unit performs load control of the electromagnetic actuator using the combined target load.
提供一种即使在车辆行驶中在减震器中产生了大输入的情形下也能够缓冲该大输入而保持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,其产生用于使车辆的车身的振动衰减的负荷;信息获取部(41),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。目标负荷运算部进行将第1目标负荷及第2目标负荷和基于行程位置的涉及假想弹簧力控制的第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。
