To suppress that it is erroneously determined to visually observe an in-vehicle device, despite the fact that a front target outside a vehicle is visually observed.SOLUTION: An inattentive state determining device 4 detects a target present in front of a vehicle, based on peripheral data indicating a situation around the vehicle; detects a viewpoint position and a visual line direction of a driver, based on driver data indicating a state of the driver; changes a visual observation determination range in a vertical direction in order to determine whether or not the driver visually observes an in-vehicle device arranged in front of a cabin thereof, according to a positional relation to the target; determines that the in-vehicle device is inattentively observed if the visual line direction of the driver is continuously kept within the visual observation determination range for a predetermined inattentive state determination time or more; and changes the visual observation determination range in such a manner that an upper end position in the visual observation determination range is made to be at a lower side by comparing when the target is located at a nearby place with when the target is located at a distance.SELECTED DRAWING: Figure 3
【課題】車外前方物標を目視しているにもかかわらず車内機器を目視していると誤判定するのを抑制する。【解決手段】脇見判定装置4は、車両の周辺の状況を表す周辺データに基づいて車両の前方に存在する物標を検出し、ドライバの状態を表すドライバデータに基づいてドライバの視点位置及び視線方向を検出し、物標との位置関係に応じてドライバが車内前方に配置された車内機器を目視しているか否かの判定を行うための上下方向の目視判定範囲を変更し、ドライバの視線方向が目視判定範囲内に所定の脇見判定時間以上継続して収まっていれば車内機器を脇見していると判定し、物標が近辺に位置するときは、遠方に位置するときと比較して目視判定範囲の上端位置が下側となるように目視判定範囲を変更する。【選択図】図3
