To provide a tire state estimation system, a tire state estimation method, and a calculation model generation method that are capable of enhancing the accuracy of estimating the state of a tire.SOLUTION: A tire state estimation system 100 comprises a vehicle information acquisition unit 12, an origin shift amount calculation unit 13, a correction processing unit 14, and a tire state estimation unit 15. The vehicle information acquisition unit 12 acquires information including acceleration data measured on the vehicle. The origin shift amount calculation unit 13 calculates an amount of origin shift having occurred in the acceleration data acquired by the vehicle information acquisition unit 12. The correction processing unit 14 corrects the acceleration data acquired by the vehicle information acquisition unit 12 on the basis of the amount of origin shift. The tire state estimation unit 15 inputs the acceleration data corrected by the correction processing unit 14 into a calculation model 15a, and estimates a state of a tire 7.SELECTED DRAWING: Figure 1

    【課題】タイヤの状態の推定精度を向上することができるタイヤ状態推定システム、タイヤ状態推定方法および演算モデル生成方法を提供する。【解決手段】タイヤ状態推定システム100は、車両情報取得部12、原点シフト量算出部13、補正処理部14およびタイヤ状態推定部15を備える。車両情報取得部12は、車両で計測される加速度データを含む情報を取得する。原点シフト量算出部13は、車両情報取得部12によって取得した加速度データに生じている原点シフト量を算出する。補正処理部14は、車両情報取得部12によって取得した加速度データを原点シフト量に基づいて補正する。タイヤ状態推定部15は、補正処理部14によって補正された加速度データを演算モデル15aに入力し、タイヤ7の状態を推定する。【選択図】図1
