To provide a drunk driving preventing device capable of suitably preventing drunk driving by an occupantSOLUTION: A drunk driving preventing device 1 includes: a first measuring sensor 10 which is attached to a vehicular seat S and measures an alcohol concentration in air within a vehicle; a second measuring sensor 20 which is attached to the vehicle and measures an alcohol concentration in breath of an occupant; and a control controller 30 having a drinking determination unit which determines the occurrence of drinking of the occupant based on measurement results of the first measuring sensor 10 and the second measuring sensor 20. The drinking determination unit has a first determination unit which determines whether or not the alcohol concentration in air is at least a first reference value and a second determination unit which determines whether the alcohol concentration in breath is a second reference value which is the first reference value or more when the alcohol concentration in air is at least a first reference value and, when the alcohol concentration in breath is the second reference value or more, determines that the passenger is drunk.SELECTED DRAWING: Figure 1

    【課題】乗員の飲酒運転を好適に防止可能な新規の飲酒運転防止装置を提供する。【解決手段】飲酒運転防止装置1は、乗り物用シートSに取り付けられ、乗り物内の空気中アルコール濃度を測定する第1測定センサ10と、乗り物に取り付けられ、乗員の呼気中アルコール濃度を測定する第2測定センサ20と、第1測定センサ10及び第2測定センサ20の測定結果に基づいて、乗員の飲酒の有無を判定する飲酒判定部を有する制御コントローラ30とを備えている。飲酒判定部は、空気中アルコール濃度が第1基準値以上であるか否かを判定する第1判定部と、空気中アルコール濃度が第1基準値以上であった場合に、呼気中アルコール濃度が第1基準値よりも高い第2基準値以上であるか否かを判定する第2判定部とを有しており、呼気中アルコール濃度が第2基準値以上であった場合に、乗員が飲酒していると判定する。【選択図】図1
