Abstract

The present invention relates to a method for determining a value of at least one state parameter of a rail vehicle and/or of a track for a railway vehicle, wherein in at least one capturing step, at least one actual first capturing signal correlated with the actual value of the state parameter is captured, via a first signal sensor on a structure in the interior of the rail vehicle, wherein, for capturing the actual first capturing signal, a first signal sensor of a mobile end device is used. For determining the value of the at least one state parameter a frequency range of the first capturing signal actual above 1 Hz to 2 Hz, preferably 4 Hz to 15 kHz, more preferably from 10 Hz to 1 kHz, is evaluated.
