Abstract

A method for monitoring the state of a bogie of a railway vehicle having at least one wheel set, wherein the wheels of the wheel set are rigidly connected by an axle and have an approximately conical wheel profile, and signals corresponding to a sinusoidal run of the wheel set of the bogie based on the conical wheel profile of the wheels are filtered out of signals provided by sensors disposed on the bogie. The frequency of the sinusoidal run is determined relative to boundary conditions, such as the prevailing vehicle speed, and compared to a save value or range of values for the frequency of the sinusoidal run typical for the prevailing boundary conditions, wherein the deviation of the measured frequency from the saved value or range of values for the frequency is monitored.
