To provide a method and a system for estimating degradation in a tire which allows a more accurate estimation of degradation in a tire.SOLUTION: A tire degradation estimation system 100 includes a sensor part 20, a physical property change calculation unit 33, and a degradation estimation unit 34. The sensor part 20 is arranged in a tire and measures the physical quantity related to at least deformation of the tire. The physical property change calculation unit 33 calculates the change of the physical property of the tire with time on the basis of the physical quantity measured by the sensor unit 20. The degradation estimation unit 34 estimates the degradation in the tire on the basis of the change in the physical property calculated by the physical property change calculation unit 33.SELECTED DRAWING: Figure 2

    【課題】タイヤの劣化をより正確に推定することができるタイヤ劣化推定システムおよびタイヤ劣化推定方法を提供する。【解決手段】タイヤ劣化推定システム100は、センサ部20、物性変化算出部33および劣化推定部34を備える。センサ部20は、タイヤに配設されており、少なくともタイヤの変形に関わる物理量を計測する。物性変化算出部33は、センサ部20により計測された物理量に基づいて、経時的なタイヤの物性の変化を算出する。劣化推定部34は、物性変化算出部33により算出された物性の変化に基づいて、タイヤの劣化を推定する。【選択図】図2
