Abstract
A vehicle abnormality detecting apparatus 1 includes wheel load sensors 11 that are attached to right and left rails R constituting a track to measure wheel loads of wheels 3 provided in a vehicle 2; and a calculation unit 12 that is connected to the wheel load sensors 11. An index represented by wheel loads of a pair or more of right and left wheels 3 provided in at least one of bogies 4 and defined according to a type of vehicle abnormality as an index for detecting the vehicle abnormality is previously stored in the calculation unit 12. The calculation unit 12 calculates a value of the stored index from the wheel loads measured by the wheel load sensors 11 and transmitted from the wheel load sensors 11, and detects the abnormality of a running vehicle based on the calculated value of the index.
