To provide a tire deterioration estimation system, a tire deterioration estimation method, and a tire deterioration diagnosis system capable of improving accuracy of tire deterioration estimation.SOLUTION: A tire deterioration estimation system 100 includes a sensor 20 and a deterioration estimation unit 32. The sensor 20 is disposed in a tire 10 and measures a physical quantity related to deformation of the tire 10. The deterioration estimation unit 32 inputs the physical quantity measured by the sensor 20 into a learning type calculation model 32a to estimate a deterioration indicator value of the tire 10. The calculation model 32a includes a feature extraction unit that extracts a feature quantity of the physical quantity measured by the sensor 20.SELECTED DRAWING: Figure 1

    【課題】タイヤの劣化推定の精度を向上することができるタイヤ劣化推定システム、タイヤ劣化推定方法およびタイヤ劣化診断システムを提供する。【解決手段】タイヤ劣化推定システム100は、センサ20および劣化推定部32を備える。センサ20は、タイヤ10に配設されており、タイヤ10の変形に関わる物理量を計測する。劣化推定部32は、センサ20により計測された物理量を学習型の演算モデル32aに入力してタイヤ10の劣化指標値を推定する。演算モデル32aは、センサ20により計測された物理量の特徴量を抽出する特徴抽出部を有する。【選択図】図1
