To prevent incorrect detection of a driver's visual recognition action.SOLUTION: A control device 10 that determines whether a driver is in a careless driving state or not based on the number of visual recognition actions in which the driver visually recognizes a predetermined direction with respect to a vehicle proceeding direction includes: a state acquisition part 32 for acquiring the driver's face-direction state; an angular speed acquisition part 33 for acquiring an angular speed when a face direction changes in the predetermined direction on the basis of the face-direction state acquired by the state acquisition part 32; and a count part 34 that counts a face-direction change in the predetermined direction as the visual recognition action when the angular speed acquired by the angular speed acquisition part 33 does not exceed a threshold value and that does not count the face-direction change in the predetermined direction as the visual recognition action when the angular speed does not exceed the threshold value.SELECTED DRAWING: Figure 1
【課題】運転者の視認行動の誤検知を抑制する。【解決手段】運転者が車両の進行方向に対して所定方向を視認する視認行動の回数に基づいて、漫然運転状態か否かを判定する制御装置10は、運転者の顔向き状態を取得する状態取得部32と、状態取得部32によって取得された顔向き状態に基づいて、所定方向における顔向き変化時の角速度を取得する角速度取得部33と、角速度取得部33によって取得された角速度が閾値を超えない場合には、所定方向における顔向き変化を視認行動としてカウントし、角速度が閾値を超えない場合には、所定方向における顔向き変化を視認行動としてカウントしないカウント部34とを備える。【選択図】図1
