Description
したがって、相対回転数設定部6030は、制御周期ΔTにて要求されるカムシャフト位相変化量Δθを生じさせるための電動モータ2060の相対回転数ΔNmを、(1)式に従った演算処理によって求めることができる。
(2)式において、DTY(FB)は、上記回転数偏差および所定の制御ゲインによる制御演算(代表的には、一般的なP制御、PI制御等)基づくフィードバック項である。
インテークカムシャフト1120の位相検出精度を向上するために、インテーク用VVT機構2000では、所定の学習指示条件成立時に、学習制御部6100により、インテークバルブ位相の基準位置学習を行なう。本発明の実施の形態では、減速比R(θ)が大きい領域で基準位置学習を行なう。具体的には、インテークバルブ位相を最遅角に到達させることにより基準位置学習が行なわれる。
基準位置学習が指示されていないため処理を終了する。
、複数バンク間でバルブタイミング制御時のバルブタイミング設定を揃えて、気筒への空気導入量のバンク間ばらつきを抑制できる。これにより、エンジンの回転変動の発生等を防止して、エンジンの燃焼性を良好に維持することができる。
