Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an electronic control device capable of detecting a failure in closing a fuel cap of a fuel tank.SOLUTION: An electronic control device 10 relating to the embodiment includes an input to a sensor 46 for detecting a pressure in a fuel tank 12, and an output for controlling a pump 44 to reduce the pressure in the fuel tank. At the time of turning on an ignition switch, it performs oil supply determination processing for determining the presence or absence of an oil supply history to the fuel tank, and when determining the presence of the oil supply history in the oil supply determination processing, it performs cap removal determination processing for determining whether a fuel cap 15 is removed from an oil supply port 14 or not.SELECTED DRAWING: Figure 3 【課題】燃料タンクの燃料キャップ閉め忘れを検出可能な電子制御装置を提供する。【解決手段】実施形態に係る電子制御装置１０は、燃料タンク１２内の圧力を検知するセンサ４６の入力と、前記燃料タンク内の圧力を減圧可能なポンプ４４を制御する出力とを備える。イグニッションスイッチのオン時に、前記燃料タンクへの給油履歴の有無を判定する給油判定処理を行い、前記給油判定処理において給油履歴有と判定された場合に、給油口１４の燃料キャップ１５外れの有無を判定するキャップ外れ判定処理を行う。【選択図】図３
