Summary:To provide a vehicle detection device, a vehicle detection method, and a vehicle detection program that can prevent erroneous detection of the presence/absence of a vehicle in a detection space, such as a parking space of a parking lot.SOLUTION: When the dispersion V of the amount of change G of a magnetic sensor 11A is determined to exceed a threshold for switching H11 by a control unit 12 of a vehicle detection device 10, status information indicating a parking state of a parking space Z1 stored in a storage unit 13 is changed to a parking state opposite to the current parking state. For example, when the status information before the determination is one indicating a full state, the status information is changed to an empty state. Thus, even when a vehicle 21 having a lower influence on geomagnetism is parked in the parking space Z1, the full state in the parking space Z1 can be accurately determined.SELECTED DRAWING: Figure 9 【課題】駐車場の駐車スペースなどの検出空間における車両の有無の誤検知を防止することが可能な車両検知装置、車両検知方法、及び車両検知プログラムを提供する。【解決手段】車両検知装置10の制御部12によって、磁気センサ11Aの変化量Gの分散Vが切替用閾値H11を超えたと判定されると、記憶部13に記憶された駐車スペースZ1の駐車状態を示すステータス情報が、現状の駐車状態とは逆の駐車状態に変更される。例えば、判定前の前記ステータス情報が満状態を示すものであった場合は、前記ステータス情報は、空状態に変更される。このため、地磁気への影響の低い車両21が駐車スペースZ1に駐車された場合でも、駐車スペースZ1における満状態を正確に判定することができる。【選択図】図9
