METHOD AND DEVICE FOR DETECTING ABNORMALITY OF VEHICLE AND SENSOR UNIT OF THE DEVICE

摘要

A method and a device for detecting the abnormality of a vehicle for detecting such an abnormal state that high temperature occurs due to the mal-adjustment of a vehicle bearing mechanism part or a vehicle brake mechanism part and a sensor unit of the device. An air temperature inside a tire (2) is detected as a first temperature by the sensor unit (100) fitted to a rim (31), and the temperature (second temperature) of the rim (31) is detected as a temperature related to at least either of the temperatures of the vehicle bearing mechanism part and the vehicle brake mechanism part (40). A difference between the first temperature and the second temperature is obtained, and when the difference is equal to or more than a prescribed value, the vehicle bearing mechanism part or the vehicle brake mechanism part (40) is determined to cause an abnormality to detect the abnormality.
