PROBLEM TO BE SOLVED: To accurately determine whether or not a driver is in an inattentive drive state.SOLUTION: A safety drive support device 2 comprises: a vehicle speed determination part 7a for determining a vehicle speed of an own vehicle; a traveling scene determination part 7d for determining a traveling scene of the own vehicle; a visual line state determination part 7e for determination a visual line state of a driver; a determination range decision part 7f for deciding a determination range by using the vehicle speed of the own vehicle and the traveling scene of the own vehicle; a determination time decision part 7g for deciding a determination time by using the vehicle speed of the own vehicle and the traveling scene of the own vehicle; and an inattentive drive state determination part 7h for determining whether or not a time at which a visual line direction of the driver is deviated from the determination range is continued for the determination time by using the visual line state of the driver, the determination range depending on the vehicle speed of the own vehicle and the traveling scene of the own vehicle, and the determination time, and determining whether or not the driver is in the inattentive state.SELECTED DRAWING: Figure 1
【課題】ドライバが脇見状態であるか否かを高い精度で判定する。【解決手段】安全運転支援装置2は、自車両の車速を判定する車速判定部7aと、自車両の走行シーンを判定する走行シーン判定部7dと、ドライバの視線状態を判定する視線状態判定部7eと、自車両の車速及び自車両の走行シーンを用い、判定範囲を決定する判定範囲決定部7fと、自車両の車速及び自車両の走行シーンを用い、判定時間を決定する判定時間決定部7gと、ドライバの視線状態と、自車両の車速及び自車両の走行シーンに依存する判定範囲及び判定時間とを用い、ドライバの視線方向が判定範囲から外れている時間が判定時間継続したか否かを判定し、ドライバが脇見状態であるか否かを判定する脇見状態判定部7hとを備える。【選択図】図1
