To solve the problem in which: an alarm may not be activated even when a driver looks in one specific direction for a relatively long time when the driver changes the direction of travel of a vehicle.SOLUTION: An inattentive driving determination device 20 comprises: data acquisition units 41 to 43 that acquire sensing data from sensors 6 to 15; a line of sight direction detection unit 47 that detects the direction of line of sight of a driver on the basis of the sensing data; an intersection recognition unit 44 that determines inattentive driving on the basis of whether the direction of line of sight is outside a predetermined angle with respect to the travel direction, and when the direction of line of sight is outside the predetermined angle, whether the time during which the direction of line of sight is outside the predetermined angle is equal to or more than a preset allowable time during which inattentive driving is allowed; an alarm control unit 49 that, when inattentive driving is determined, outputs a signal to instruct activation of an alarm; a travel direction determination unit 45 that determines a change in travel direction on the basis of the sensing data; and a time changing unit 46 that, when an intersection is recognized and a change in travel direction is determined, reduces the allowable time.SELECTED DRAWING: Figure 2

    【課題】車両の進行方向の変更時、運転者が、比較的長い時間、特定の一方向しか見ていない場合であっても、警報が発報されないことがある。【解決手段】脇見判定装置20は、センサ6〜15から、センシングデータを取得するデータ取得部41〜43と、センシングデータに基づいて運転者の視線方向を検出する視線方向検出部47と、視線方向が、進行方向に対する所定の角度から外れているか否か、外れている場合には、視線方向が所定の角度から外れている時間が、脇見が許容される予め設定された許容時間以上か否かに基づいて脇見を判定する交差点認識部44と、脇見が判定された場合、警報を行うように指示する信号を出力する警報制御部49と、センシングデータに基づいて進行方向の変更を判定する進行方向判定部45と、交差点が認識され、進行方向の変更が判定された場合、許容時間を短縮する時間変更部46とを備える。【選択図】図2
