Abstract:
1. A vehicle abnormality detection method for using a vehicle abnormality detection device to detect an abnormality of at least one of a vehicle bearing mechanism section and a vehicle brake mechanism section in a vehicle provided with a tire including a tire wheel and a tire body mounted in the tire wheel, the method characterized in that the abnormality detection device senses as a first temperature any one of an air temperature within tire and a tire body temperature by a first temperature sensing element inside a sensor unit housing, senses as a second temperature a temperature related to at least one of a temperature of the vehicle bearing mechanism section and a temperature of the vehicle brake mechanism section by a second temperature sensing element inside said sensor unit housing, characterized in that the second temperature sensing element is arranged to sense a temperature of the tire wheel as the second temperature, calculates a temperature difference between the first and second temperatures, and determines, upon the temperature difference being a predetermined value or more, that an abnormality has occurred in the vehicle bearing mechanism section or the vehicle brake mechanism section and thereby detects the abnormality.
