Document Type and Number:

WIPO Patent Application WO/2010/064453

Kind Code:

A1

Abstract:

Provided is a method of detecting a warning sign of derailment, which can be performed with high accuracy and is easy to be applied to a vehicle. The pitch angle velocity and the roll angle velocity of a running truck are detected by sensors mounted on a truck frame or on an axle box and the truck frame. The condition that the measured truck pitch angle velocity or the integrated value of the truck pitch angle velocity becomes more than a threshold value set in advance and the measured truck roll angle velocity or the integrated value of the truck roll angle velocity becomes more than a threshold value set in advance is determined as a warning sign of derailment.
