A distraction determination device (1) changes a determination reference range of a distraction determination unit (27) by a predetermined angle in a curve direction by a determination reference range changing unit (28) on the basis of curve direction information detected by a curve detection unit (26), and changes a distraction reference range of a distraction determination unit (27) by a predetermined angle in a line-of-sight direction of a driver detected by a line-of-sight direction detection unit (24) along the following direction. That is, when the relative direction of the other vehicle detected by the other vehicle detection unit 30 is acquired by the relative direction acquisition unit 31 when the own vehicle is regarded as a reference, the state of distraction is not determined even if the line-of-sight direction is out of a determination reference range that does not conform to the state of distraction. This makes it possible to suppress an improper determination of a distraction state even when there is a vehicle other than the vehicle showing a behavior of going to go to a lane of the own vehicle.
一种分心判定装置1,基于由弯道检测部26所检测的弯道方向的信息,利用判定基准范围变更部28将分心判定部27的判定基准范围向弯道方向变更规定角度,另一方面,在由视线方向检测部24检测到的驾驶员的视线方向沿着如下方向,即关于由他人车辆检测部30检测到的他人车辆由相对方向获取部31获取的将自己车辆视为基准时的他人车辆的相对方向时,即便该视线方向朝向不符合分心状态的判定基准范围之外,也不判定为分心状态。由此,即便存在显示出要向自己车辆的行车道并线的行为的他人车辆时,也可抑制分心状态的不恰当判定。
