Abstract
Methods and apparatus are provided for detecting whether a tire rotation event or tire inflation even has occurred on a vehicle. The method comprises determining a first front average temperature (FAT) of a first front tire and a second front tire, determining a first rear average temperature (RAT) of a first rear tire and a second rear tire, and calculating a first ratio of the first FAT to the first RAT. The method further comprise determining a second FAT of the first front tire and the second front tire after determining the first FAT, determining a second RAT of the first rear tire and the second rear tire after determining the first RAT, calculating a second ratio of the second FAT to the second RAT, and identifying the tire rotation event based at least in part upon a comparison of the first ratio and the second ratio.
