To prevent a vehicle from falling in a dangerous state in a case where a driver becomes awakened state from a non-awakened state during over-ride operation.SOLUTION: A drive assistance device according to the present invention is a drive assistance device for assisting in driving a vehicle such that, in a case where an operation for driving is started by a driver during automatic operation, the automatic operation is switched to manual operation. The drive assistance device comprises an acquiring section and a determining section. The acquiring section acquires a state of the driver. In a case where the state of the driver, acquired when the operation is started, is a non-awakened state, the determining section makes a determination so as to cancel switching to the manual operation and, in a case where the state of the driver shifts to an awakened state during the cancellation, it makes a determination so as to continue the cancellation for a predetermined period.SELECTED DRAWING: Figure 2A
【課題】オーバライド操作中に運転者が非覚醒状態から覚醒状態となった場合に、車両が危険な状態に陥るのを防止すること。【解決手段】実施形態に係る運転支援装置は、自動運転中に運転者により運転に関する操作が開始された場合に、自動運転を手動運転へ切り替えるよう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、取得部と、判定部とを備える。取得部は、運転者の状態を取得する。判定部は、上記操作が開始された際に取得された運転者の状態が非覚醒状態である場合に、手動運転への切り替えを無効にするように判定するとともに、かかる無効中に運転者の状態が覚醒状態へ推移した場合は、所定期間の間、上記無効を継続するように判定する。【選択図】図2A
