To provide a parking state detection system and a parking state detection method capable of suppressing erroneous parking detection even for a vehicle giving a large influence to a magnetic field.SOLUTION: A parking state detection system 10 comprises a sensor device 11, a sensor device 12, and a management device 20. The sensor device 11 including a geomagnetic sensor 111 is arranged in a first parking space. The sensor device 12 including a geomagnetic sensor 121 is arranged in a second parking space close to the first parking space. A fluctuation detection unit 112 of the sensor device 11 detects a first fluctuation value from a fluctuation of an output value of the geomagnetic sensor 111. A fluctuation detection unit 122 of the sensor device 12 detects a second fluctuation value from a fluctuation of an output value of the geomagnetic sensor 121. A calculation unit 201 of the management device 20 detects a parking state of the first parking space or a parking state of the second parking space by using a comparison result of magnitudes of the first fluctuation value and the second fluctuation value.SELECTED DRAWING: Figure 1 【課題】磁場への影響が大きな車両であっても、駐車の誤検出を抑制できる駐車状態検出システム、駐車状態検出方法を提供する。【解決手段】駐車状態検出システム１０は、センサ装置１１、センサ装置１２、および、管理装置２０を備える。地磁気センサ１１１を含むセンサ装置１１は、第１の駐車マスに配置されている。地磁気センサ１２１を含むセンサ装置１２は、第１の駐車マスに近接する第２の駐車マスに配置されている。センサ装置１１の変動検出部１１２は、地磁気センサ１１１の出力値の変動から第１変動値を検出する。センサ装置１２の変動検出部１２２は、地磁気センサ１２１の出力値の変動から第２変動値を検出する。管理装置２０の演算部２０１は、第１変動値と第２変動値との大きさの比較結果を用いて、第１の駐車マスの駐車状態または第２の駐車マスの駐車状態を検出する。【選択図】図１
