Document Type and Number:

WIPO Patent Application WO/2020/203233

Kind Code:

A1

Abstract:

An arithmetic model generation system 100 is provided with: a tire information acquisition unit 31; a position information acquisition unit 32; a wear amount calculation unit 33; and an arithmetic model update unit 34. The tire information acquisition unit 31 acquires tire data including the temperature and pressure of a tire 10. The position information acquisition unit 32 acquires position data on a vehicle on which the tire 10 is mounted. The wear amount calculation unit 33 has an arithmetic model 33b for calculating the tire wear amount on the basis of the temperature, pressure, and position, and calculates the wear amount of the tire 10 using the arithmetic model 33b by inputting the tire data and the position data corresponding to the tire data. The arithmetic model update unit 34 compares a wear amount measured on the tire 10 and the wear amount calculated by the wear amount calculation unit 33, and updates the arithmetic model 33b.
