- 少なくとも距離センサを含む検出部による検出結果に基づいて、車両の運転者における複数の骨格部位の相対的な位置関係を含む運転姿勢を認識する認識部と、
正常な運転状態における当該運転者の前記運転姿勢である複数の正常運転姿勢を記憶する記憶部と、
前記記憶部に記憶された複数の前記正常運転姿勢のそれぞれに対して、当該正常運転姿勢と前記認識部で認識した前記運転姿勢とのズレ量を算出するズレ量算出部と、
前記記憶部に記憶された複数の前記正常運転姿勢のそれぞれに対して算出された前記ズレ量のうち、最も値が小さい前記ズレ量を最小ズレ量として選択する最小ズレ量選択部と、
前記最小ズレ量選択部で選択された前記最小ズレ量を積算してズレ量積算値を算出する積算値算出部と、
前記積算値算出部で算出された前記ズレ量積算値が、予め定められた閾値を超えた場合に前記運転者の状態が異常と判定する判定部と、を備え、
前記積算値算出部は、前記最小ズレ量選択部で選択された前記最小ズレ量を積算するとともに、所定時間が経過する毎に前記ズレ量積算値を所定量減算する、運転者状態判定装置。 - 前記判定部による判定時以外のときに、前記認識部で認識した当該運転者の前記運転姿勢を前記正常運転姿勢として前記記憶部に記憶する学習部を備える、請求項1に記載の運転者状態判定装置。
