To prevent erroneous detection of a full/vacant state of a vehicle to a vehicle cabin.SOLUTION: A vehicle detection device 10 comprises a magnetic sensor 11 arranged on a ground surface of a vehicle cabin; a detection value acquisition part 121 for acquiring a periodic detection value based on detection at a geomagnetism level from the magnetic sensor 11; a first full/vacant state determination part 122 for determining a vacant state, when the detection value is lower than a vacancy threshold value; and a second full/vacant state determination part 123 for switching determination between a full state and a vacant state when a difference of both detection values before and after detecting a peak exceeds a predetermined difference threshold value, in a case where the peak of the detection value acquired corresponding to one region of a vehicle exceeds a full threshold value, and the detection value after the peak is converged to between the full threshold value and the vacancy threshold value.SELECTED DRAWING: Figure 5 【課題】車室に対する車両の満空状態の誤検知を防止する。【解決手段】車両検知装置１０は、車室の地面に設置された磁気センサ１１と、磁気センサ１１からの地磁気レベルの検出に基づいて周期的な検出値を取得する検出値取得部１２１と、検出値が空閾値よりも低い場合、空状態と判定する第１の満空状態判定部１２２と、車両の一部位に対応して取得される検出値のピークが満閾値を超え、かつピーク後の検出値が満閾値と空閾値との間に収束した場合に、ピークの検出の前後における両検出値の差分が所定の差分閾値を超えると、満状態と空状態との間の判定を切り替える第２の満空状態判定部１２３とを備える。【選択図】図５
