Description
図1に示されるように、第1実施形態に係る運転意識推定装置100は、自車両(車両)の運転者(以下、単に「運転者」ともいう)の運転意識に関する運転構え度の推定を行う装置である。なお、運転構え度については後述する。運転意識推定装置100は、自車両の自動運転を実行する自動運転システムの一部を構成していてもよい。
次に、第2実施形態について説明する。第2実施形態の説明では、第1実施形態と異なる点を説明し、重複する説明は省略する。
次に、第3実施形態について説明する。第3実施形態の説明では、第1実施形態と異なる点を説明し、重複する説明は省略する。
推奨運転構え度の元値=
α×(平均車速/最小曲率半径)×(1/平均車間距離)
Claims (3)
- 車両の運転者の反応時間と、前記運転者の脇見時間及び覚醒度の双方と、に基づいて、前記運転者の運転意識に関する運転構え度を推定する運転構え度推定部を備え、
前記運転構え度推定部が推定する前記運転構え度に前記反応時間が与える影響は、当該運転構え度に前記脇見時間及び前記覚醒度の双方が与える影響よりも大きく、
前記車両の運転が自動運転から手動運転へ切り替わるまでに要される時間と、前記車両の運転が自動運転から手動運転に切り替わった後に前記運転者に必要な能力であるタスクディマンドとに基づいて、推奨運転構え度を決定し、
前記運転構え度及び前記推奨運転構え度の両方の状態を、表示部に表示する、運転意識推定装置。 - 前記運転構え度推定部は、反応時間を認識不能の場合には、前記脇見時間及び前記覚醒度のみに基づいて運転構え度を推定する、請求項1に記載の運転意識推定装置。
- 前記車両の自動運転を実行する自動運転システムの一部を構成する、請求項1又は2に記載の運転意識推定装置。
