Description
LIFT=LTDC (1)
ここで、LTDCはTDC信号の計測回数に応じて設定されるリフト量である。
LIFT=LTDC+Lpi (2)
ここで、LTDCは(1)式と同様にTDC信号の計測回数に応じて設定されるリフト量である。LpiはPIフィードバックにより決まるリフト量であり、次式のように表すことができる。
Lpi=―Kp×NE―Ki×Σ(NE―Nobj) (3)
ここで、NEはエンジン回転数であり、Nobjはエンジン回転数NEの目標値(ここではアイドル回転数)である。KpおよびKiはそれぞれ比例ゲインおよび積分ゲインである。
LIFT(今回値)=LIFT(前回値)+ΔL (4)
ここで、ΔLは単位時間ステップごとに変更するリフト量である。

32 TDCセンサ
40 可変動弁機構
42 可変リフト機構
46 スロットル弁
57 エンジン水温センサ
