To achieve both of the reduction of a time taken for the determination of an abnormality in a driver and the improvement of accuracy in the determination.SOLUTION: A driver abnormality determination device includes: an involuntary function detection section 420 which detects the exertion level of the involuntary function of a driver on the basis of the detection data of a driver state sensor 67; a driving function detection section 430 which, when driving operation is performed by the driver, detects the exertion level of the driving function of the driver on the basis of the detection data of a driving operation sensor 66; and an abnormality determination section 440 which determines an abnormality in the driver when the exertion level of the driving function has become equal to or lower than a prescribed determination criterion. When the exertion level of the involuntary function has lowered to be equal to or lower than a prescribed criterion, the abnormality determination section 440 reduces the threshold of the determination criterion for the exertion level of the driving function.SELECTED DRAWING: Figure 5

    【課題】ドライバの異常判定までの時間短縮と精度向上を両立させる。【解決手段】ドライバ異常判定装置は、ドライバ状態センサ67の検出データに基づいて、ドライバの不随意機能の発揮レベルを検知する不随意機能検知部420と、ドライバの運転操作がある場合に、運転操作センサ66の検出データに基づいてドライバの運転機能の発揮レベルを検知する運転機能検知部430と、運転機能の発揮レベルが所定の判定基準以下になった場合に、ドライバの異常を判定する異常判定部440とを備える。異常判定部440は、不随意機能の発揮レベルが所定の基準以下に低下した場合に、運転機能の発揮レベルについての判定基準の閾値を小さくする。【選択図】図5
