Claims (3)
- 内燃機関を備えた車両に設けられた燃料タンク内で発生した蒸発燃料を吸着するキャニスタと、
前記キャニスタと前記燃料タンクとを接続するベーパ通路と、
前記ベーパ通路に設けられ、前記ベーパ通路を閉鎖及び開通可能な封鎖弁と、
前記封鎖弁を動作させるステッピングモータと、
前記封鎖弁を現在位置から閉方向の動作限界に基づいて設定される初期位置に移動させる初期化処理を実行する制御手段と、
を備え、
前記制御手段は、前記封鎖弁の前記現在位置が不明となる特定事象が生じて前記初期化処理が必要になった場合には、前記封鎖弁を現在位置に関わりなく前記動作限界まで動作させることが可能な前記ステッピングモータの動作量として設定された第1動作量で、前記ステッピングモータを動作させる第1処理を前記初期化処理として行う一方で、前記特定事象が生じることなく前記初期化処理が必要になった場合には、前記封鎖弁を前記現在位置から前記初期位置まで動作させることが可能なように設定された前記ステッピングモータの動作量であり、かつ前記第1動作量よりも少ない第2動作量で、前記ステッピングモータを動作させる第2処理を前記初期化処理として行うことを特徴とする蒸発燃料処理装置。 - 前記第1動作量のステップ数は、前記封鎖弁を開方向の動作限界から閉方向の動作限界まで動作させることが可能な動作量のステップ数よりも多くなるように設定されている、請求項1に記載の蒸発燃料処理装置。
- 前記制御手段は、前記第1処理を行っている間に生じる前記ステッピングモータの脱調を検出し、前記脱調を検出した位置を前記初期位置として記憶するとともに、前記初期位置に前記封鎖弁を停止させて前記第1処理を終了する、請求項1又は2に記載の蒸発燃料処理装置。
