Abstract
A method for monitoring the driving behavior of a railway vehicle, wherein at least one measurement variable characterizing the vibrational behavior of at least one wheel set of the railway vehicle, is captured by at least one sensor providing a corresponding measurement signal. The method includes the steps of identifying at least one significant event or a combination of multiple significant events within the time trace of the measurement signal and identifying the event time at which the significant event took place, deriving the frequency from the time trace of the measurement signal starting from the event time, comparing the derived frequency to at least one stored reference frequency, evaluating the vibrational behavior of the wheel set as a function of the deviation of the derived frequency from the at least one stored reference frequency.
