Abstract
A method and device for detecting a derailment state of a rail vehicle, wherein at least one kinematic variable is respectively measured via first and second sensors with respect to first and second wheelset end portions and corresponding measurement signals are formed, processed and evaluated, where values of first and second falling velocities y with respect to the first and second wheelset end portions are respectively calculated from the measurement signals via a computing unit and a derailment state of the rail vehicle is detected via a first comparison operation of the first falling velocity and the second falling velocity with a first falling velocity limit value and a second falling velocity limit value, which has a greater magnitude than the first falling velocity limit value such that a high level of certainty in the detection of derailment states is achieved.
