Title:
TIRE WEAR LIFE ESTIMATING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2017/149954
Kind Code:
A1
Abstract:
Provided is a tire wear life estimating system capable of predicting an amount of wear of a tire accurately and efficiently. This tire wear life estimating system includes: a vehicle travel data generating unit (1, 2) which generates and stores data relating to vehicle parameters of a vehicle which is traveling on a travel path extending from a start point to an end point of straight-line sectors or curved sectors while traveling repeatedly in accordance with travel patterns comprising acceleration, deceleration and turning, where said vehicle parameters include, for example, the vehicle speed, the travel pattern and a tire steering amount; a trajectory information generating unit (3, 4) which generates and stores data pertaining to gradient, curve length and the like relating to the travel path; a vehicle model generating unit (5, 6) which generates and stores vehicle specifications and the like; and a friction energy calculating unit (7) which calculates total friction energy of the tires in all sectors of the travel path by calculating friction energy for each travel mode for each sector of the travel pattern, on the basis of the data stored by the vehicle travel data generating unit (1, 2), the trajectory information generating unit (3, 4), and the vehicle model generating unit (5, 6), and adding together the friction energy calculated for each sector.
