PROBLEM TO BE SOLVED: To provide a driver's undrivable state detector capable of highly accurately detecting that a driver is in an undrivable state.SOLUTION: A driver's undrivable state detector comprises: facial-direction detection means directing a direction of a driver's face with respect to a front of a vehicle 10 on the basis of a driver seat image picked up by a driver camera 21 mounted in a vehicle 10; and facial-direction off-balance state detection means detecting that the driver is in an undrivable state if the direction of the driver's face detected by the facial-direction detection means is greater than a facial-direction threshold for time longer than facial-direction off-balance determination time during the running of the vehicle 10.
【課題】ドライバが運転不能状態となったことを高精度に検出できるドライバの運転不能状態検出装置を提供する。【解決手段】車両10に搭載されたドライバカメラ21により撮像された運転席の画像に基づいて、車両10の前方に対するドライバの顔の向きを検出する顔向き検出手段と、車両10の走行中に、顔向き検出手段により検出されたドライバの顔の向きが、向き崩れ判定時間を超えて顔向き閾値よりも大きい場合に、ドライバが運転不能状態であることを検出する向き崩れ状態検出手段と、を備える。【選択図】 図1
