A device for estimating the acceleration of a vibrational component acting on a vehicle body in a lateral direction when a railway vehicle having a vehicle body tilting device runs in a curve section includes a sensor for detecting the acceleration acting on the vehicle body in a lateral direction, a calculation unit for acquiring track information at a running point, a running speed, and ON/OFF information of vehicle body tilting operation, and calculating a theoretical excess centrifugal acceleration alphaL acting on the vehicle body by equations, and a calculation unit for deriving the acceleration of the vibrational component acting on the vehicle body based on the acceleration detected by the sensor and the acceleration alphaL determined by the calculation unit. Vibration generated in the vehicle body in a lateral direction is suppressed, so that the acceleration of the vibrational component can be estimated.
