Abstract (en)
[origin: WO2004101343A1] The invention relates to a method and device for recognizing a derailment state of wheel (RAD) of a railway vehicle, in which the acceleration of the wheel (RAD) perpendicular to a rail plane ( epsilon ) is measured by at least one acceleration sensor (SEN). A rate of fall (FAG) of the wheel (RAD) in the direction of the rail plane ( epsilon ) is determined based on an acceleration signal (BSI), which is produced by the acceleration sensor (SEN), by simple integration (INT) of a value that can be predetermined over a time window, and the existence of a derailed state is verified based on the determined rate of fall (FAG).
