To make a driver aware of switching from automatic drive to manual drive more reliably.SOLUTION: A drive assisting device 10, which assists drive of a vehicle, provided to enable traveling while switching between automatic drive control and manual drive control, comprises a monitoring section 11a, a determining section 11d, and a condition setting section 11b. The monitoring section 11a monitors an abnormal state of a driver. The determining section 11d gives a caution to the driver in a case where a degree of abnormal state based on a monitoring state of the monitoring section 11a exceeds a predetermined caution threshold. In a case where the vehicle is switched from automatic drive to manual drive, the condition setting section 11b enhances a determining condition of the determining section 11d such that a caution is more likely to be given for a predetermine period from the start of such manual operation.SELECTED DRAWING: Figure 2A
【課題】自動運転から手動運転への切り替えに際して、運転者をより確実に覚醒状態へ導くこと。【解決手段】運転支援装置10は、自動運転制御および手動運転制御を切り替えつつ走行可能に設けられた車両の運転を支援する運転支援装置であって、監視部11aと、判定部11dと、条件設定部11bとを備える。監視部11aは、運転者の異常状態を監視する。判定部11dは監視部11aの監視結果に基づく異常状態の度合いが所定の警告閾値を超える場合に運転者に対する警告を行わせる。条件設定部11bは車両が自動運転から手動運転へ切り替えられた場合に、かかる手動運転の開始から所定期間の間は警告が行われやすくなるように判定部11dの判定条件を強化する。【選択図】図2A
