SERVER DEVICE AND DETERMINATION SYSTEM

PROBLEM TO BE SOLVED: To provide a server device and a determination system which determine whether a vehicle is present in a garage and in which an adverse effect of heat on a coil is diminished.SOLUTION: In a determination system 1, a server device 30 determines whether a vehicle is present in a garage. The server device receives a first electromagnetic characteristic value, which represents an inductance value of a first coil detected at a first time, and second electromagnetic characteristic values, which represent inductance values of a second coil detected at plural times earlier than a second time identical to or immediately preceding the first time, from a detector 10 including the first coil 11 and the second coil 12a smaller than the first coil, and compensates an adverse effect of heat, which the first electromagnetic characteristic value detected at the first time incurs, using the second electromagnetic characteristic value or values detected at one time or the plural times preceding the second time identical to or immediately preceding the first time.SELECTED DRAWING: Figure 1 【課題】車両の入庫の有無を判定すると共にコイルが受ける熱の影響が低減されたサーバ装置及び判定システムを提供する。【解決手段】判定システム１においてサーバ装置３０は、車両の入庫の有無を判定する。サーバ装置は、第１コイル部１１と第１コイル部よりも小さい第２コイル部１２ａを備える検出装置１０から、第１時刻に検出された第１コイル部のインダクタンス値を示す第１電磁気的特性値と、第１時刻と同じ又は直近の第２時刻以前の複数の時刻に検出された前記第２コイル部のインダクタンス値を示す第２電磁気的特性値とを受信し、第１時刻に検出された第１電磁気的特性値が受ける熱の影響を、第１時刻と同じ又は直近の第２時刻以前の一又は複数の時刻において検出された第２電磁気的特性値を用いて補正する。【選択図】図１
