To estimate attitude state information indicating an attitude state of an occupant of a vehicle seat using electric characteristics of a vehicle seat having a flexible material having conductivity without using a special detection device.SOLUTION: An estimation device detects electric characteristics among a plurality of detection points in a vehicle seat having a flexible material which has conductivity and has electric characteristics varying according to the change of an imparted pressure by a detection unit. An estimation unit estimates an attitude state of an occupant of the vehicle seat from the electric characteristics of the vehicle seat using a learning model. The learning model is learned to input the electric characteristics and output the attitude state information, using the electric characteristics when a pressure is given to the vehicle seat and the attitude state information indicating the attitude state of the occupant giving a pressure to the vehicle seat as data for learning, so as to input the electric characteristics and output the attitude state of the occupant corresponding to the input electric characteristics.SELECTED DRAWING: Figure 1

    【課題】特殊な検出装置を用いることなく、導電性を有する柔軟材料を備えた車両用シートの電気特性を利用して、車両用シートの乗員の姿勢状態を示す姿勢状態情報を推定する。【解決手段】推定装置は導電性を有し、かつ付与された圧力の変化に応じて電気特性が変化する柔軟材料を備えた車両用シートにおける複数の検出点の間の電気特性を検出部で検出する。推定部は、学習モデルを用いて車両用シートの電気特性から車両用シートの乗員の姿勢状態を推定する。車両用シートに圧力を与えた際の電気特性と、車両用シートに圧力を与える乗員の姿勢状態を示す姿勢状態情報とを学習用データとして用いて、その電気特性を入力とし、姿勢状態情報を出力するように学習された学習モデルに対して、電気特性を入力し、入力した電気特性に対応する乗員の姿勢状態を出力するように学習される。【選択図】図1
