To provide an electrically powered suspension apparatus which, even in a case where a large input is applied to a damper during the traveling of a vehicle, can maintain a comfortable ride by buffering such a large input.SOLUTION: An electrically powered suspension apparatus 11 includes: an electromagnetic actuator 13 for generating a load for damping the vibration of a vehicle body of a vehicle 10; an information acquisition section 41 for acquiring information on the sprung state quantity of the vehicle 10 and a travel road surface state; a target load calculation section 43 for calculating a first target load related to skyhook control based on the sprung state quantity, and a second target load related to preview control based on the travel road surface state; and a load control section 45 for performing the load control of the electromagnetic actuator 13. The target load calculation section 43 calculates a combined target load obtained by combining the first and second target loads and a third target load related to virtual spring force control based on a stroke position ST. The load control section 45 performs the load control of the electromagnetic actuator 13 by using the combined target load.SELECTED DRAWING: Figure 3
