The invention relates to 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, such as the displacement, the velocity, or the acceleration of the wheel set, or the force acting on the wheel set is captured by at least one sensor (2) providing a corresponding measurement signal. The method according to the invention comprises the following steps: - identifying at least one significant event or a combination of multiple significant events within the time trace of the measurement signal, wherein the measurement variable exceeds a prescribed minimum value, and identifying the event time at which said significant event took place, - deriving the frequency from the time trace of the measurement signal starting from the event time, wherein the frequency is derived for a defined duration (t) 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. |
