Description
図1は、ガソリンエンジン(以下、エンジンと表記)20の吸気系を示す構成図である。エンジン20は、内燃機関の一例であるが、これに限定されず、エンジン20に代えてディーゼルエンジンが用いられてもよい。エンジン20は、ピストン24が収納されたシリンダブロック21上に設置されたシリンダヘッド22内の燃焼室23内で混合気を燃焼させて、ピストン24を往復動させる。ピストン24の往復動は、クランクシャフト26の回転運動に変換される。なお、エンジン20としては、例えば4つの気筒を有した直列4気筒エンジンが挙げられるが、これに限定されない。
図2は、比較例におけるECU6のデータ処理を示す図である。エアフローメータ15は、一例として0.846(ms)の送信周期で測定データをECU6に送信する。ここで、測定データの送信周期は第1周期の一例である。
図9は、実施例におけるECU6のデータ処理を示す図である。図9において、図2と共通する構成には同一の符号を付し、その説明は省略する。ECU6は、プロセッサ70がプログラムを読み込んで実行することにより、機能として通信処理部60、格納部61a、平均化処理部63、及び演算処理部62を形成する。なお、符号Fbは、図2に示される比較例の構成と相違する部分である。この部分の処理は比較例より高速化されている。
