To provide fuel theft detection method and a fuel theft detection device which can detect theft precisely.SOLUTION: A fuel gauge 10 detects residual quantity of fuel by using a residual sensor 11 every 100 ms and sequentially calculates average values of residual quantity detected this time and residual quantity detected until pre-prescribed frequency. In addition, the fuel gauge 10 sequentially modifies an average value calculated before so that difference becomes a prescribed value if difference of an average value calculated this time and the average value calculated before is greater than the prescribed value. A server device 40 sequentially calculates the difference subtracting an average value of formerly calculated post-modification of post-modification from an average value calculated this time of post-modification and sequentially calculates integrated values of difference calculated this time and difference calculated until pre-constant period (t-s). The server device 40 detects theft of the fuel on the basis of the integrated value.SELECTED DRAWING: Figure 4

    【課題】精度よく盗難を検出することができる燃料盗難検出方法及び燃料盗難検出装置を提供する。【解決手段】燃料計10が、100ms毎に残量センサ11を用いて燃料の残量を検出し、今回検出された残量と、所定回数前までに検出された残量と、の平均値を順次、算出する。また、燃料計10が、今回算出された平均値と、前回算出された平均値と、の差分が所定値より大きい場合、差分が所定値となるように、前回算出された平均値を順次、修正する。サーバ装置40が、修正後の今回算出された平均値から修正後の前回算出された修正後の平均値を差し引いた差分を順次、算出し、今回算出された差分と、一定期間(t-s)前までに算出された差分と、の積算値を順次、算出する。サーバ装置40が、積算値に基づいて燃料の盗難を検出する。【選択図】図4
