Description
(1)車両構成要素毎の過給圧調整値のうち最小値を過給圧設定値とする。
(2)車両構成要素毎の過給圧調整値のうち最大値と最小値との間の中間値を過給圧設定値とする。
ことが考えられる。この場合、上記(1)によれば、過給圧の過上昇を確実に抑制することが可能となる。また、上記(2)によれば、過給圧の過上昇抑制を図りつつも、車両構成要素毎の過給圧調整値のバランスを取って最適な過給圧設定値の設定が可能となる。上記(2)は、過給圧設定値として目標過給圧を設定する場合に特に有効である。
Claims (1)
- 吸入空気を過給する過給機を備えたエンジンに適用され、エンジン運転条件等に応じて設定した過給圧設定値に基づいて前記過給機の過給状態を制御する過給状態制御手段を備えた過給機付きエンジンの制御装置において、
前記過給機による過給状態が高過給圧であることにより影響を受ける複数の車載部品について各車載部品の運転条件を検出する運転条件検出手段と、
前記過給機による過給圧を上限ガードするための過給圧ガード値を、前記運転条件検出手段により検出した運転条件に基づいて前記車載部品毎に設定するガード値設定手段と、を備え、
前記過給状態制御手段は、前記ガード値設定手段により設定した車載部品毎の過給圧ガード値を比較し、そのうち最も小さい過給圧ガード値を前記過給圧設定値とし、その過給圧設定値により前記過給機の過給圧を制限することを特徴とする過給機付きエンジンの制御装置。
