Abstract
Description
タンク内圧センサ15により検出される燃料タンク10の内圧Ptkが標準大気圧よりも低い第1閾値Pa以下であるか、あるいは標準大気圧よりも高い第2閾値Pb以上である場合に実行される。図2に示すように、開弁開始位置学習ルーチンの開始に際して、ECU8(図示しないCPU)は、まず学習中断履歴フラグFiの値を入力する(ステップS100)。学習中断履歴フラグFiは、本ルーチンが前回の実行時に正常に完了した場合に値0に設定されると共に、本ルーチンが前回の実行時に中断されて正常に完了しなかった場合に値1に設定されるものである。続いて、ECU8は、学習中断履歴フラグFiの値に基づいて学習の中断履歴の有無を判定する(ステップS110)。
Claims (1)
- 燃料タンクとキャニスタとを結ぶベーパ通路に設置されると共に弁座に対して軸方向に進退移動する弁体を有する封鎖弁と、前記封鎖弁を開閉制御すると共に、前記弁体と前記弁座との軸方向距離を変化させたときの前記燃料タンクの内圧変化に基づいて前記封鎖弁の開弁開始位置を学習する制御装置とを含む蒸発燃料処理装置において、
前記制御装置は、前記開弁開始位置の学習中に該学習を中断させる際に、中断直前の前記軸方向距離の指令値を記憶しており、前記学習の中断後に次の前記開弁開始位置の学習タイミングが到来した際に、前記中断直前の前記軸方向距離の指令値を初期指令値として前記開弁開始位置の学習を実行することを特徴とする蒸発燃料処理装置。
