Abstract (en)

[origin: WO2018073331A1] The invention relates to a method and to a device for detecting roll motion of a rail vehicle car body (1) relative to the bogie (2) of a rail vehicle (3), wherein a signal ( S ) proportional to the roll motion is bandpass-filtered and the magnitude of the bandpass-filtered signal ( S filter) is compared with a limit value ( S lim) and rolling is determined on the basis of the limit value ( S lim) being exceeded several times within an observation time period ( T ).
