System and method for quantitative analysis of cause of tire trouble
First Claim
1. A system for quantitative analysis of a cause of tire trouble, comprising a positional data receiving means for receiving positional data of a running vehicle from the GPS,an acceleration measuring means for measuring triaxial accelerations which are accelerations acting on the running vehicle in back-and-forward, right-and left and up-and-down directions while time synchronizing with the positional data received by the positional data receiving means,a database portion for storing the positional data received by the positional information receiving means and the triaxial acceleration data measured by the acceleration measuring means,a data analyzing means for quantitatively analyzing harshness of a tire using condition, anda display means for displaying an analysis result from the data analyzing means.

Abstract
There is provided a system and method for quantitative analysis of a cause of tire trouble capable of quantitatively analyzing whether the tire trouble is caused by the tire itself or in a matter of harshness of a tire using condition in light of not only a force acting on a tire mounted on a running vehicle but also harshness of a tire using condition such as a traveling speed of the vehicle, level difference of a road surface, a curve and gradient information. The method for quantitative analysis of a cause of tire trouble according to the present invention is characterized by comprising the steps of receiving positional data of a running vehicle from the GPS, simultaneously measuring triaxial accelerations which are accelerations acting on the running vehicle in back-and-forward, right-and-left and up-and-down directions while time synchronizing with the received data, quantitatively analyzing harshness of a tire using condition from the received positional data and the triaxial acceleration data, and displaying an analysis result.
