PROBLEM TO BE SOLVED: To increase accuracy in determining whether or not a driver is in an inattentive driving state.SOLUTION: A safety driving support device 2 comprises: a line-of-sight determination part 7b for determining a line-of-sight of a driver; a driving load level calculation part 7c for calculating a driving load level of the driver; a driving load level determination part 7d which, when the calculation of the driving load level of the driver has been successfully performed, determines the calculated driving load level of the driver; and an inattentive driving state determination part 7g for determining whether or not the driver is in an inattentive driving state. When the direction of the line-of-sight of the driver is deviated from the traveling direction of the vehicle, the inattentive driving state determination part 7g determines that the driver is in an inattentive driving state if the driving load level of the driver is less than a prescribed level and determines that the driver is not in an inattentive driving state if the driving load level of the driver is not less than the prescribed level.SELECTED DRAWING: Figure 1
【課題】運転者が脇見状態であるか否かを判定する精度を高める。【解決手段】安全運転支援装置2は、運転者の視線方向を判定する視線方向判定部7bと、運転者の運転負荷レベルを算出する運転負荷レベル算出部7cと、運転者の運転負荷レベルの算出に成功すると、その算出された運転者の運転負荷レベルを判定する運転負荷レベル判定部7dと、運転者が脇見状態であるか否かを判定する脇見状態判定部7gとを備える。脇見状態判定部7gは、運転者の視線方向が車両の進行方向から外れているときに、運転者の運転負荷レベルが所定レベル以上でなければ、運転者が脇見状態であると特定し、運転者の運転負荷レベルが所定レベル以上であれば、運転者が脇見状態でないと特定する。【選択図】図1
