To provide a driver state grasping device which can judge accurately whether it is in the state where a driver can take over a driving operation, especially a steering wheel operation quickly during automatic driving from grasping a state of an object by the driver's hand.SOLUTION: An driver state grasping device 20 for grasping a state of a driver 4 of a vehicle 2 provided with an automatic driving system 1 is comprised of: an image acquisition unit 22a for acquiring an image photographed by a camera 31 for photographing the driver 4; a hand detection unit 22b that detects a hand of the driver 4 from the image acquired by the image acquisition unit 22a; an object holding state detection unit 22c that detects a hand holding state of an object by the hand of the driver 4 detected by the hand detection unit 22b; and an immediate responsiveness determination unit 22d that determines whether or not the driver 4 can immediately operate a steering wheel 5 of the vehicle 2 during the automatic driving based on the gripping state of the object detected by the object gripping state detection unit 22c.SELECTED DRAWING: Figure 3
【課題】自動運転中に運転者が運転操作、特にハンドル操作を迅速に引き継ぐことができる状態にあるか否かを、運転者の手による物体の把持状態から正確に判定することができる運転者状態把握装置を提供すること。【解決手段】自動運転システム1を備えた車両2の運転者4の状態を把握する運転者状態把握装置20であって、運転者4を撮影するカメラ31で撮影された画像を取得する画像取得部22aと、画像取得部22aで取得した画像から運転者4の手を検出する手検出部22bと、手検出部22bで検出された運転者4の手による物体の把持状態を検出する物体把持状態検出部22cと、物体把持状態検出部22cにより検出された物体の把持状態に基づいて、自動運転中に運転者4が車両2のハンドル5をすぐに操作できる状態にあるか否かを判定する即応性判定部22dとを装備する。【選択図】図3
