Two or more front-side vibration suppression force generation sources and two or more rear-side vibration suppression force generation sources are interposed between bogies and the vehicle body. A controller calculates a sway high-frequency vibration suppression force for suppressing vibration having a frequency which is not less than a frequency of a centrifugal acceleration acting on the vehicle body when the railway vehicle runs in a curve section. The controller lets at least a part of the front-side vibration suppression force generation sources and at least a part of the rear-side vibration suppression force generation sources output a resultant force of a yaw suppression force and the sway high-frequency vibration suppression force. The controller lets all the remaining vibration suppression force generation sources function as passive dampers when the railway vehicle runs in the curve section. Ride quality of the vehicle in the curve section is thereby improved.
