To provide a tire physical information estimating system and a tire physical information estimating method capable of continuously estimating physical information of a tire even when some sensors fail.SOLUTION: A data acquisition unit 31 of a tire physical information estimation system 100 acquires data of a physical quantity measured by a sensor 20 attached to a plurality of tires 10 mounted on a vehicle. A physical information estimation unit 33 estimates tire physical information generated by the movement of the tire 10 with respect to the tire 10 and the other tires 10 by an arithmetic model 33a learned for each tire 10. A physical information estimation unit 33 estimates the tire physical information of the tire 10 to which the sensor 20 having acquired the information that the tire has failed from a sensor fault information acquisition unit 32 is attached, based on the arithmetic model 33a of the tire 10 to which the sensor 20 having acquired the information that the tire has not failed is attached.SELECTED DRAWING: Figure 2

    【課題】一部のセンサが故障した場合にもタイヤに関する物理情報を継続的に推定することができるタイヤ物理情報推定システムおよびタイヤ物理情報推定方法を提供する。【解決手段】タイヤ物理情報推定システム100のデータ取得部31は、車両に装着された複数のタイヤ10に取り付けられたセンサ20によって計測される物理量のデータを取得する。物理情報推定部33は、タイヤ10の運動によって生じるタイヤ物理情報を、タイヤ10ごとに学習済みの演算モデル33aによって当該タイヤ10と他のタイヤ10について推定する。物理情報推定部33は、センサ故障情報取得部32で故障しているとの情報が取得されたセンサ20が取り付けられたタイヤ10のタイヤ物理情報を、故障していないとの情報が取得されたセンサ20が取り付けられたタイヤ10における演算モデル33aに基づいて推定する。【選択図】図2
