To determine whether a driver's state is suitable or not for driving.SOLUTION: An on-vehicle device 10 includes: a travel support controller 30 which detects that guidance related to driving operation has been performed with respect to a driver; a sight line detector 32 which detects a sight line direction of the driver; a condition determination unit 33 which determines whether or not watching conditions are established including a condition that the driver's sight line is directed in a watching direction, with regard to a preset watching direction, from detection of the guidance until a first reference time has passed, and a condition that the driver's sight line is directed in the watching direction for a second reference time or longer; and a driver state determination unit 34 which determines whether or not the driver is in a state capable of driving, on the basis of a determination result of the condition determination unit 33.SELECTED DRAWING: Figure 1
【課題】運転者の状態が運転に適した状態か否かを判定する。【解決手段】車載装置10は、運転者に対して運転操作に関する案内が行われたことを検知する走行支援制御部30と、運転者の視線の方向を検出する視線検出部32と、案内を検知してから第1基準時間が経過するまでに、予め設定された注視方向について、運転者の視線が注視方向を向いていること、及び、運転者の視線が注視方向を向いている時間が第2基準時間以上であることを含む注視条件が成立したか否かを判定する条件判定部33と、条件判定部33の判定結果に基づいて、運転者が運転可能な状態であるか否かを判定する運転者状態判定部34と、を備える。【選択図】図1
