To provide a driver state estimating device which maximizes an accuracy of estimating a driver's state when a vehicle is running, even in a place where there is a little change in an external environment.SOLUTION: A driver state estimating device 20 is comprised of: a line-of-sight detection device (vehicle interior camera 101 and line-of-sight calculation unit 53) which detects a line-of-sight direction of a driver; a display device (head-up display 10 and display control unit 52) which displays a specific display according to a driving scene of a vehicle in a line-of-sight area of the driver when the vehicle is running; an estimation unit 56 which estimates that the driver has an abnormality when the line-of-sight direction of the driver does not turn to the specific display within a threshold time after the display device displays the specific display; and a threshold setting unit 57 for setting the threshold time according to a position where the specific display is displayed.SELECTED DRAWING: Figure 3

    【課題】外部環境の変化が少ない場所であっても、車両走行時における運転者の状態を推定する精度を出来る限り高くする運転者状態推定装置を提供する。【解決手段】運転者状態推定装置20は、運転者の視線方向を検知する視線検知装置(車室内カメラ101及び視線算出部53)と、車両の走行時における運転者の視線領域に、車両の走行シーンに応じた特定表示を行う表示装置(ヘッドアップディスプレイ10及び表示制御部52)と、運転者の視線方向が、表示装置が前記特定表示を表示してから、閾値時間以内に特定表示に向かなかったときに、運転者に異常が生じていると推定する推定部56と、特定表示を表示する位置に応じて閾値時間を設定する閾値設定部57とを備える。【選択図】図3
