Description
上記構成によれば、排気再循環通路を介して吸気通路に戻される燃料やガスの量はほとんど「0」である。そのため、燃料噴射弁からの燃料噴射量に応じた狙いの目標温度まで速やかにパティキュレートフィルタを昇温させることができる。
まず、ハイブリッド車両におけるハイブリッドシステムの概略構成について説明する。
図1に示すように、ハイブリッド車両は、内燃機関10と、内燃機関10のクランク軸14に接続されている動力配分統合機構40と、動力配分統合機構40に接続されている第1のモータジェネレータ71とを備えている。動力配分統合機構40には、リダクションギア50を介して第2のモータジェネレータ72が連結されるとともに、減速機構60及びディファレンシャル61を介して駆動輪62が連結されている。
図1に示すように、ハイブリッド車両の制御装置100は、アクセル開度ACC及び車速VSを基に、リングギア軸45に出力すべきトルクである要求トルクTQRを算出する。アクセル開度ACCは、車両の運転者によるアクセルペダルAPの操作量のことであり、アクセル開度センサ84によって検出された値である。車速VSは、車両の移動速度に対応する値であり、車速センサ85によって検出される。制御装置100は、算出した要求トルクTQRを基に、内燃機関10、各モータジェネレータ71,72を制御する。
ステップS310において、噴射弁制御部112は、燃料噴射弁17における燃料噴射量の要求値QPRを「0」に設定する。そして、噴射弁制御部112は、続くステップS320において、要求値QPRを基に燃料噴射弁17の駆動を制御する。つまり、この場合には、燃料噴射弁17からは燃料が噴射されない。噴射弁制御部112は、ステップS320の処理を実行すると、一連の処理を一旦終了する。これらステップS310及びステップS320の処理は、内燃機関10のクランク軸14が回転している状況下で気筒11内での燃焼を停止させ、且つ燃料を気筒11内に導入しない燃料カット処理である。
上記の構成においては、燃料導入処理の実行条件が成立すると、バルブ制御部114によって制限処理が実行され、排気再循環バルブ26の開度が制限される。具体的には、燃料導入処理の実行条件が成立すると、バルブ制御処理におけるステップS510及びステップS520の処理が繰り返されて、排気再循環バルブ26の開度が「0」となるように当該排気再循環バルブ26が制御される。そして、排気再循環バルブ26の開度が「0」に至った後、燃料導入処理は開始される。排気再循環バルブ26の開度は、燃料導入処理の実行中、すなわち噴射弁制御処理におけるステップS50及びステップS60の処理が繰り返される全期間に亘って「0」に制御される。そして、燃料導入処理が終了すると、すなわち噴射弁制御処理におけるステップS50及びステップS60の処理が繰り返される期間が終了すると、排気再循環バルブ26の開度を「0」にする制御は解除される。
・制限処理において排気再循環バルブ26の目標開度EGVとして定められる導入用開度EGV1は、燃料導入処理の実行条件が成立した状態に切り替わったタイミングの排気再循環バルブ26の開度である事前開度WGVよりも小さければよく、必ずしも「0」でなくてもよい。排気再循環バルブ26の開度が「0」でなくとも、当該排気再循環バルブ26の開度が小さく制限されてさえいれば、三元触媒22で昇温したガスが排気再循環通路25を介して吸気通路15へと戻されてしまうことを少なからず抑制できる。
