METHOD, APPARATUS, AND PROGRAM FOR DETECTING TIRE HAVING DECREASED AIR PRESSURE

A method for detecting a tire having decreased air pressure based on wheel rotation information obtained from the tire attached to a vehicle in which there is a predetermined difference between front and rear wheel loads. The method includes the steps of acquiring wheel rotation information obtained...

description A method for detecting a tire having decreased air pressure based on wheel rotation information obtained from the tire attached to a vehicle in which there is a predetermined difference between front and rear wheel loads. The method includes the steps of acquiring wheel rotation information obtained from the tire, storing the wheel rotation information, acquiring a load sensitivity of a tire dynamic loaded radius due to load shift during turning, acquiring speed dependency of the load sensitivity, comparing load sensitivity of the tire dynamic loaded radius at a speed acquired based on the speed dependency with preliminarily stored load sensitivities of dynamic loaded radiuses of various tires, estimating decreased pressure sensitivity of the tire dynamic loaded radius based on a result of the comparison, and determining that the tire has a decreased air pressure based on a result of the estimation.
