Description
以下、図面を参照して、本発明の各種実施形態について説明する。
<実施形態の構成>
始めに、図1を参照し、本発明の第1実施形態に係るハイブリッド車両1の構成について説明する。ここに、図1は、ハイブリッド車両1の構成を概念的に表してなる概略構成図である。
Ter=Te×1/(1+ρ)・・・(2)
MG2減速機構600は、車軸に繋がる駆動軸500とモータジェネレータMG2との間に介装された、サンギアS2、リングギアR2、ピニオンギア(不図示)及びキャリアC2の各回転要素を備えた遊星歯車機構である。MG2減速機構500において、サンギアS2は、モータジェネレータMG2のロータに固定された出力回転軸に固定されている。また、キャリアC2は、ハイブリッド駆動装置10の外郭ケースに回転不能に固定されている。更に、リングギアR2は、駆動軸500に連結されている。係る構成において、MG2減速機構500は、モータジェネレータMG2の回転速度Nmg2を、駆動軸800に対し、各回転要素(ギア)のギア比に応じて定まる減速比に従って減速して伝達することが出来る。
ここで、図3を参照し、本実施形態の動作として外部給電制御の詳細について説明する。ここに、図3は、外部給電制御のフローチャートである。尚、外部給電制御は、ECU100が上位で実行する制御の一サブルーチンとして、外部給電制御の実行条件が満たされた場合に実行される。外部給電制御は、例えば、ハイブリッド車両1の停止時において、プラグ50に受電設備(例えば、上述した家電製品等)の受電プラグが差し込まれた場合等に実行される。
(2)第2措置(故障診断処理における故障診断基準の緩和措置)
(3)第3措置(MIL点灯制限措置)
(4)第4措置(故障履歴の記憶制限措置)
項目B:三元触媒220の損傷
項目C:パージ装置のエバポ供給ライン故障
項目D:空燃比センサ221の断線
項目E:O2センサ222の全般故障
項目F:CSS(触媒暖機)
項目G:EGR装置の故障
項目H:冷却水循環装置のサーモスタットの故障
項目I:VVTの故障
項目J:ISC装置の故障
項目K:燃料系(PFI212)の故障
次に、図6を参照して、本発明の第2実施形態として、エンジン始動制御について説明する。ここに、図6は、エンジン始動制御のフローチャートである。尚、エンジン始動制御は、外部給電制御と同様に一種のサブルーチンである。エンジン始動制御は、外部給電における始動要求とは異なり、イグニッション操作やスタートボタン操作等によりエンジン200の始動が要求された場合に実行される。
