To solve the problem in which: when a vehicle travels on a straight downhill, even though a driver performs a necessary checking action, which is not inattentive driving, the action is erroneously determined as inattentive driving, and an alarm is activated.SOLUTION: An inattentive driving determination device 10 comprises: an imaging data acquisition unit 31 that acquires imaging data of a driver; an inattentive driving determination unit 36 that determines inattentive driving on the basis of images of the direction of the face and the line of sight of the driver picked up in the imaging data and a determination reference; a travel state acquisition unit 32 that acquires travel state data of the vehicle; a travel state determination unit 33 that determines that the vehicle travels toward a downward direction on the basis of the travel state data; and a determination reference changing unit 34 that changes a determination reference for the direction of the face and the line of sight in an upward direction of the driver, in a state where the vehicle is determined to travel toward a downward direction, compared with a state where the vehicle is not determined to travel toward a downward direction.SELECTED DRAWING: Figure 2

    【課題】車両が直進の下り坂を走行している場合、運転者は、脇見ではない必要な確認行為を行ったにも関わらず、脇見と誤判定され、警報が発報される。【解決手段】脇見判定装置10は、運転者の撮像データを取得する撮像データ取得部31と、撮像データに撮像された運転者の顔向きおよび視線と、判定基準とに基づいて、脇見を判定する脇見判定部36と、車両の走行状態データを取得する走行状態取得部32と、走行状態データに基づいて、車両が下り方向に向かって走行していることを判定する走行状態判定部33と、車両が下り方向に向かって走行していると判定されている状態では、車両が下り方向に向かって走行していると判定されていない状態よりも、運転者の上方向への顔向きおよび視線に対する判定基準を変更する判定基準変更部34とを備える。【選択図】図2
