METHOD AND DEVICE FOR CALCULATING INITIAL ERROR CORRECTION COEFFICIENT OF TIRE, PNEUMATIC PRESSURE LOWERING DETECTOR USING THE DEVICE, AND PROGRAM FOR CALCULATING INITIAL ERROR CORRECTION COEFFICIENT OF TIRE

摘要

PROBLEM TO BE SOLVED: To provide a method for calculating the initial error correction coefficient of a tire capable of accurately and rapidly performing an initialization by running on a course and increasing the accuracy of detection of pressure reduction.;SOLUTION: This method of calculating the correction coefficient for correcting the initial error of the tire based on the information on rotation obtained from the tire mounted to a vehicle comprises the steps of calculating the turning radius of the vehicle from the information on rotation of the tire, calculating the traveling route of the vehicle from the information on rotation of the tire and the turning radius, storing the traveling route of the vehicle, storing the information on route for a traveling course obtained from the information on terrain in which the vehicle travels, comparing the information route for the traveling route and the traveling course, and calculating the coefficient for correcting the initial error of the tire based on the comparison.;COPYRIGHT: (C)2003,JPO
