Description
開示の車両制御装置は、燃焼モードを切り替え可能な内燃機関を備える車両を制御する車両制御装置であって、内燃機関を第1燃焼モードから前記第1燃焼モードよりも空燃比が大きい第2燃焼モードに切り替える際に、前記内燃機関の吸気量が第1所定量まで増加した後に空燃比を切り替えるように前記内燃機関を制御する第1制御手段と、前記第1燃焼モードから前記第2燃焼モードへの切り替えに付随して前記吸気量が増加している所定期間中の少なくとも一部において、前記内燃機関の回転数の低下を抑制する抑制動作を行うように前記内燃機関を制御する第2制御手段とを備える。
開示の車両制御装置の他の態様では、前記第2制御手段は、(i)前記所定期間のうち前記吸気量が前記第1所定量よりも小さい第2所定量まで増加するまでの第1期間に前記抑制動作を行うと共に、(ii)前記所定期間のうち前記吸気量が前記第2所定量まで増加した後の第2期間に前記抑制動作を行わない。
開示の車両制御装置の他の態様では、前記車両は、前記内燃機関と連結されている回転電機を更に備えており、前記抑制動作が行われている期間中の前記内燃機関の出力の少なくとも一部を用いて回生発電するように前記回転電機を制御する第3制御手段を更に備える。
はじめに、図1を参照して、本実施形態の車両10の構成について説明する。ここに、図1は、本実施形態の車両10の構成の一例を示すブロック図である。
以下、上述した構成を有する車両10の動作について説明を進める。
車両10が走行する際には、主として発電機として機能するモータジェネレータMG1、主として電動機として機能するモータジェネレータMG2、及び、エンジン200の夫々の動力配分がECU100及び動力分割機構300により制御されることで、車両10の走行状態が制御される。
図2を参照しながら、エンジン200の運転状態をストイキ燃焼モードからリーン燃焼モードへと切り替える切替動作について説明する。図2は、エンジン200の運転状態をストイキ燃焼モードからリーン燃焼モードへと切り替える切替動作の流れを示すフローチャートである。
100 ECU
101 空燃比制御部
102 動作点制御部
103 回生制御部
200 エンジン
300 動力分割機構
400 インバータ
500 バッテリ
MG1、MG2 モータジェネレータ
00の回転数を維持することに代えて、エンジン200の回転数を増加させて
もよい。つまり、動作点制御部102は、エンジン200の回転数を、要求動作点がスト
イキ領域からリーン領域へと遷移すると判定された時点の回転数よりも高い回転数にまで
増加させてもよい。
