Claims (1)
- エンジンに設けられ過給または制動回生可能な電動ターボチャージャと、該電動ターボチャージャを制御する制御部と、エンジンの運転状態と排気ガスの空燃比との関係をマップとして記憶する記憶部と、排気ガスの空燃比を検出する空燃比検出手段とを備え、前記制御部は、前記記憶部の前記マップから空燃比を読み取り、該空燃比を目標空燃比とし、前記空燃比検出手段で検出された検出空燃比が前記目標空燃比より低いとき前記電動ターボチャージャを駆動してブースト圧を上げ、前記検出空燃比が前記目標空燃比より高いとき前記検出空燃比が前記目標空燃比以下になるまで前記電動ターボチャージャで制動回生させ続けてブースト圧を下げるように構成されたことを特徴とする過給制御装置。
