To reduce an erroneous determination that a driver is not looking ahead carefully when the driver does not need to look ahead carefully.SOLUTION: A safe driving determination device 4 comprises a state identification unit 421 for identifying a state of a vehicle S, an angular value calculation unit 422 for calculating an angular value indicating a driver's face direction angle with respect to a traveling direction, and a determination unit 423 for determining whether the driver is looking ahead carefully when the difference between the angular value and a reference angular value is equal to or greater than a threshold. The angular value calculation unit 422 inputs a calculated angular value to the determination unit 423 when a state identified by the state identification unit 421 is a state where the driver is not permitted to fail to look ahead carefully, and inputs an angular value whose difference from the reference angular value is less than the threshold to the determination unit 423 when the state identified by the state identification unit is a state where the driver is permitted to fail to look ahead carefully.SELECTED DRAWING: Figure 1

    【課題】運転者が前方を注視する必要がない状態において運転者が前方不注視であると誤判定しづらくする。【解決手段】安全運転判定装置4は、車両Sの状態を特定する状態特定部421と、進行方向に対する運転者の顔向き角度を示す角度値を算出する角度値算出部422と、角度値と基準角度値との差が閾値以上である場合に、運転者が前方不注視状態であるか否かを判定する判定部423と、を有し、角度値算出部422は、状態特定部421が特定した状態が、前方不注視状態であることが許容されない状態である場合に、算出した角度値を前記判定部423に入力し、状態特定部が特定した前記状態が、前方不注視状態であることが許容される状態である場合に、基準角度値との差が閾値未満の値を角度値として前記判定部423に入力する。【選択図】図1
