To provide an apparatus for appropriately estimating a state of a user.SOLUTION: A state estimation apparatus 1 for estimating a state of a user comprises: a dazzling degree estimation unit 10 which estimates a dazzling degree and its certainty degree on the basis of sensing data acquired by a camera 30 and an illuminance sensor 31; a drowsiness degree estimation unit 12 which estimates a drowsiness degree and its certainty degree; an occupant state estimation unit 14 which estimates a state of an occupant and its certainty degree obtained by adjusting the dazzling degree and the drowsiness degree; and an ambiguity elimination interference unit 16 which interferes the state of the occupant on the basis of an ambiguity elimination model when the certainty degree of the state of the occupant has a predetermined threshold or less, the apparatus then updating determination parameters 11 and 13 to use for estimation by the dazzling degree estimation unit 10 and the drowsiness degree estimation unit 12 on the basis of a result of the interference by the ambiguity elimination interference unit 16.SELECTED DRAWING: Figure 1
【課題】ユーザの状態を適切に推定する装置を提供する。【解決手段】状態推定装置1は、ユーザ状態を推定する装置であって、カメラ30及び照度センサ31にて取得したセンシングデータに基づいて、眩惑度とその確信度を推定する眩惑度推定部10、眠気度とその確信度を推定する眠気度推定部12と、眩惑度と眠気度を調整した乗員状態とその確信度とを推定する乗員状態推定部14と、乗員状態の確信度が所定の閾値以下のときに、曖昧性解消モデルに基づいて乗員状態の推論を行う曖昧性解消推論部16と、曖昧性解消推論部16の推論結果に基づいて眩惑度推定部10及び眠気度推定部12での推定に用いる判断パラメタ11,13を更新する。【選択図】図1
