Description
を備えた車両に搭載される。そして、制御装置は、アクチュエータ制御部と、停止時位相設定部と、燃焼停止処理部と、モータリング指示部とを備える。アクチュエータ制御部は、開閉タイミングの目標値と現在値との偏差に応じてアクチュエータの作動量を制御する。停止時位相設定部は、内燃機関の停止指示に応答して、目標値を所定値に設定する。燃焼停止処理部は、内燃機関の停止指示に応答して、内燃機関での燃料燃焼を停止する。モータリング指示部は、内燃機関の停止指示に応答して、回転電機によって内燃機関を所定時間モータリングさせる。
御することにより、MG(1)200の出力トルクあるいは回生トルクを適宜に設定するようになっている。その制御は、ECU100によって行なわれる。なお、MG(1)200のステータ(図示せず)は固定されており、回転しないようになっている。
により検出された蓄電装置700の温度、電圧および電流は、ECU100へ伝達される。ECU100は、これらのセンサ値に基づいて、蓄電装置700の残存容量(SOC:State of Charge)を推定する。SOCは、通常、満充電状態を100%とし、全く充電されていない状態を0%とした充電率(%)により示される。一般に、ハイブリッド車では、蓄電装置700が回生電力を受入れられるように、また要求があれば直ちに電力を供給できるようにするために、その充電率は中間値(50〜60%)に制御される。
トルクは、MG(2)400の出力トルクを変速比に応じて増大させたトルクとなるが、変速過渡状態では各ブレーキ561,562でのトルク容量や回転数変化に伴う慣性トルクなどの影響を受けたトルクとなる。また、出力軸600に付加されるトルクは、MG(2)400の駆動状態では、正トルクとなり、被駆動状態では負トルクとなる。
エンジン1000は、「A」バンク1010と「B」バンク1012とに、それぞれ4つの気筒(シリンダ)からなる気筒群が設けられたV型8気筒エンジンである。なお、V型8気筒以外の形式のエンジンを用いるようにしてもよい。
ルブ1110は、エキゾーストカムシャフト1130に設けられたエキゾースト用VVT機構3000により、位相(開閉タイミング)が制御される。
進角領域にある場合には、インテーク用VVT機構2000全体の減速比は、R(2)(R(1)>R(2))となる。
止できる。逆に言うと、このようなインテークバルブ位相の変化を防止するためには、エンジン停止時点のインテークバルブ位相を、確実に減速比の大きい遅角領域6001内とすることが必要である。
したがって、バルブ位相検出部152は、(1)式に従って算出される位相変化量Δθ
の積算によっても、現在のバルブ位相CAを検出することができる。
次に、エンジン1000の停止処理時におけるVVT機構2000の制御について説明する。
における第1の制御例を説明するブロック図である。
である、低温時および/または低SOC時において、モータリングを非実行とするように、モータリング指示部110に指示する。このようにすると、低温あるいは低SOC時に無理にモータリングのためのパワーを供給させることによって蓄電装置700がダメージを被って、次回のエンジン始動時に十分なパワーを出力できなくなってエンジン始動に支障が生じることを防止できる。
いて。ステップS150のYES判定時において、ステップS130の実行前に図20のステップS200およびS210を実行することによって、上記のような組合わせに従う制御構成を実現できる。このような構成とすると、運転者によるエンジン停止指示(手動)の発生時に、第3の制御例のように、不適切あるいは不要なモータリングの実行を回避できる。
