To appropriately notify a driver of a vehicle of a message so that automatic driving can be continued.SOLUTION: A notification device detects a predetermined action of a driver from a driver image including a face region in which the face of the driver of the vehicle of which the travel is controlled by an automatic driving system is represented, outputs a certainty factor showing certainty in detection, specifies a message for suppressing a control termination action applicable to a termination condition of control by the automatic driving system with possibility of being performed following the detected predetermined action, and notifies the driver of the specified message via the output device when an efficacy level to be calculated by multiplying the certainty factor by first probability by which the control termination action is suppressed when the driver is notified of the specified message or multiplying the certainty factor by second probability by which the control termination action is performed when the driver is not notified of the specified message is larger than a predetermined notification threshold.SELECTED DRAWING: Figure 7

    【課題】自動運転を継続できるよう車両の運転者に適切にメッセージを通知する。【解決手段】通知装置は、自動運転システムにより走行が制御されている車両の運転者の顔が表される顔領域を含む運転者画像から運転者の所定の行動を検出するとともに、当該検出における確からしさを示す確信度を出力し、検出された所定の行動に続いて行われる可能性のある、自動運転システムによる制御の終了条件に該当する制御終了行動を抑制するためのメッセージを特定し、確信度に、特定されたメッセージを運転者に通知した場合に制御終了行動が抑制される第1の確率を乗じ、または、特定されたメッセージを運転者に通知しなかった場合に制御終了行動が行われる第2の確率を乗じて算出される有効性レベルが所定の通知閾値よりも大きい場合に、出力装置を介して特定されたメッセージを運転者に通知する。【選択図】図7
