- a railroad vehicle is run on a predetermined route while changing the running speed in advance.
- the maximum value of the vertical acceleration in a predetermined frequency range generated in the vehicle body above the spring device is measured for each changed traveling speed.
- a critical vertical acceleration as a threshold value for detecting derailment is determined for each traveling speed.
- P Detects the actual vertical acceleration generated in the body.

- the frequency range is a frequency range in which the absolute value of the allowable vertical acceleration for ensuring the riding comfort is set to a minimum. In such a frequency range, the difference in vertical acceleration between normal running and derailment becomes clear, so that derailment can be detected accurately and reliably.
- Another method for detecting derailment of a railway vehicle according to the present invention is applied to a railway vehicle having a bogie including wheels rolling on rails and a spring device, and a vehicle body to which the bogie is mounted.
- this derailment detection method when a railway vehicle travels on a rail, the vertical acceleration generated in the vehicle body above the spring device is detected. Then, the vertical displacement is calculated by double integrating the vertical acceleration every predetermined evaluation time. As a result, the amount of displacement of the portion above the spring device in the vertical direction per evaluation time is obtained. If the railcar derails, the part above the spring device will descend by more than a predetermined amount. Therefore, the vertical displacement is negative and its absolute value P

It is determined for each traveling speed based on the maximum value of the directional acceleration.
- the vehicle speed detecting means detects an actual traveling speed of the railway vehicle traveling on the route.
- the acceleration detecting means detects an actual vertical acceleration generated in the vehicle body above the spring device when the railway vehicle travels on the route.
- the filter means extracts a component of the actual vertical acceleration in the above frequency range. Then, the determining means determines that the railway vehicle has derailed when the absolute value of the actual vertical acceleration in the frequency range exceeds the limit vertical acceleration corresponding to the actual traveling speed.

In each case, the vertical acceleration is double integrated to calculate the vertical displacement. Then, the determining means determines that the railroad vehicle has derailed when the vertical displacement amount is negative and the absolute value is greater than or equal to a predetermined reference value.
