Claims (1)
- 内燃機関が、排気エネルギにより駆動されるタービンとタービンにより駆動されて吸入空気を圧縮するコンプレッサとを有する過給機と、コンプレッサの上流に設けられる吸気絞り弁と、コンプレッサの上流で、かつ吸気絞り弁の下流に排気ガスの一部を還流させる排気ガス再循環装置とを備え、吸気絞り弁の上流で検出する空気流量と吸気絞り弁の下流かつ排気ガスが還流する全ての箇所よりも下流で検出する吸気管圧力との一方に基づいて吸入空気量を検出するガソリンエンジンである内燃機関の吸入空気量検出方法であって、
内燃機関の負荷を検出し、
検出した負荷が低負荷である場合は吸気管圧力に基づいて吸入空気量を検出し、
検出した負荷が低負荷を除く負荷である場合は空気流量に基づいて吸入空気量を検出する内燃機関の吸入空気量検出方法。
