Vehicle abnormality diagnosis system
First Claim
1. A vehicle abnormality diagnosis system for acquiring an operating parameter under a specified operating condition of a vehicle, a value of the operating parameter changing during an operation of the vehicle, and for diagnosing a vehicle abnormality on the basis of the value of the acquired operating parameter, whereineither a specified point or a specified area, at which the vehicle operating condition becomes the specified operating condition, is set beforehand from among points or areas on a travel route along which the vehicle travels, and an operating parameter of a point in time, at which the vehicle passed either the specified point or the specified area, is acquired, and an abnormality of a vehicle is diagnosed on the basis of a value of the acquired operating parameter.

Abstract
Either a specified point Q or a specified area Ar, at which an operating condition of a vehicle becomes a specified operating condition, is set beforehand from among points or areas on a travel route along which a vehicle travels. Then, an operating parameter P of a point in time ts1, ts2, ts3, ts4 . . . , tsn, at which a vehicle passes either a specified point Q or a specified area Ar, is obtained. Then, a vehicle abnormality is diagnosed on the basis of the values of these obtained operating parameters P (maximum values Pmax).
