To provide a tire physical information estimation system, a calculation model generation system and a tire physical information estimation method which can construct a simplified calculation model to estimate physical information concerning a tire.SOLUTION: A tire physical information estimation system 100 comprises a physical information estimation part 32 and a data acquisition part 31. The physical information estimation part 32 has a learning-type calculation model 32a extending from an input layer to an output layer, which estimates tire physical information that is generated by motion of a tire 10. The data acquisition part 31 acquires data input to the input layer. The calculation model 32a has a feature extraction part that executes convolution calculation in which a filter is set in a first combination of the tire 10, a vehicle and a road surface condition, and a fully coupled part learnt in a second combination different from the first combination.SELECTED DRAWING: Figure 2

    【課題】演算モデルを簡易的に構築してタイヤに関する物理情報を推定することができるタイヤ物理情報推定システム、演算モデル生成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は、物理情報推定部32およびデータ取得部31を備える。物理情報推定部32は、入力層から出力層に至る学習型の演算モデル32aを有し、タイヤ10の運動によって生じるタイヤ物理情報を推定する。データ取得部31は、入力層への入力データを取得する。演算モデル32aは、タイヤ10、車両および路面状態の第1組合せにおいてフィルタが設定された畳み込み演算を実行する特徴抽出部、および第1組合せとは異なる第2組合せにおいて学習した全結合部を有する。【選択図】図2
