Description
アルコールとガソリンとの混合燃料がエンジンオイルに混入してエンジンオイルが希釈されている場合、希釈燃料が揮発する量が少ない一方で、オイル温度がアルコールの沸点に近づくと、希釈燃料は、急激に気化する。すなわち、混合燃料を用いる場合、ブローバイガスの燃料濃度が急激に高くなる虞がある。このため、燃料カット処理を実行しているとき、触媒の過昇温が突発的に引き起こされる虞がある。混合燃料を使用する車両では、空気量制御弁の駆動に異常が生じている場合でも触媒に導入する空気量を確保することによって触媒の温度の上昇を抑制することのできる上記構成が特に有効である。
図1は、車両100と、車両100の制御装置10と、を示している。車両100は、走行用の動力源として内燃機関とモータジェネレータとを搭載する、いわゆるハイブリッド車両である。車両100は、内燃機関20と、内燃機関20のクランク軸32に接続されている動力配分統合機構50と、動力配分統合機構50に接続されている第1モータジェネレータ81と、を備えている。さらに、車両100は、第2モータジェネレータ82を備えている。第2モータジェネレータ82は、リダクションギア60を介して動力配分統合機構50に連結されている。車両100の駆動輪72は、減速機構70及びディファレンシャル71を介して動力配分統合機構50に連結されている。
第2モータジェネレータ82は、発電機として機能することができる。車両100を減速させる際に、第2モータジェネレータ82を発電機として機能させることによって、第2モータジェネレータ82の発電量に応じた回生制動力が発生する。
図1に示すように、車両100は、燃料タンク44を備えている。燃料タンク44には、内燃機関20に供給する燃料が貯留される。なお、車両100は、アルコールとガソリンとが混合された混合燃料を使用可能な、いわゆるFFV(Flexible Fuel Vehicle)である。内燃機関20は、アルコール濃度100%の燃料、アルコール濃度0%の燃料、またはアルコールとガソリンとが任意の割合で混合された燃料を用いて運転することができる。
(A)希釈燃料の推定値である希釈量DAが規定の希釈閾値DAth以上である。
(B)冷却水温TWが規定の温度閾値TWth以上である。
(C)アルコール濃度ALが規定の濃度閾値ALth以上である。
本処理ルーチンが開始されると、まずステップS101において、異常診断部13は、可変動弁機構41の異常を検出する診断処理を実行する。診断処理の実行後、処理がステップS102に移行される。ステップS102の処理では、ステップS101において実行された診断処理によって可変動弁機構41に異常が検出されなかった場合、すなわち、異常がない場合(S102:NO)、本処理ルーチンが一旦終了される。
本処理ルーチンが開始されると、まずステップS201において、昇温抑制処理の開始条件が成立しているか否かが空気増量部14によって判定される。開始条件が成立していない場合(S201:NO)、本処理ルーチンが一旦終了される。一方、開始条件が成立している場合(S201:YES)、処理がステップS202に移行される。ステップS202では、機関制御部11が燃料カット処理の実行を要求しているか否かが空気増量部14によって判定される。燃料カット処理の要求がない場合(S202:NO)、本処理ルーチンが一旦終了される。一方、燃料カット処理の要求がある場合(S202:YES)、処理がステップS203に移行される。
図6は、図6の(a)に示すように車両100が減速しているとき、燃料カット条件が成立して燃料カット処理の実行が要求されている例を示している。図6の(b)に示すように、燃料カット処理の実行は、タイミングt1において開始されている。なお、図6に示す例では、診断処理によって、可変動弁機構41の異常が検出されており、VVT異常フラグは、オンにセットされている。
(1)図6に比較例として示したように、可変動弁機構41に異常が生じている場合に昇温抑制処理においてスロットル開度TAを全開にするだけでは、吸入空気量GAが少ない。このため、触媒導入空気量が不足し、触媒温度TCの上昇を抑制できないことがある。
「前記気筒に導入する吸入空気量を変更する空気量制御弁」は、吸気バルブ24に対応する。また、「前記空気量制御弁の駆動に異常が生じている場合」は、吸気バルブ24のバルブタイミングを変更する可変動弁機構41に異常が生じている場合に対応する。
・上記実施形態において異常診断部13が実行する診断処理では、可変動弁機構41の異常をより詳細に判定してもよい。そして、診断処理の結果に応じて、空気増量部14が実行する昇温抑制処理による制御態様を変更してもよい。
図7は、昇温抑制処理を実行しているときの、吸入空気量GAと触媒温度TCと希釈量DAとの関係を示している。図7に示すように、希釈量DAが少ない場合と比較して希釈量DAが多い場合には、希釈量DAが多いほど、吸入空気量GAを増大させても触媒温度TCが低下しにくくなる。こうした傾向は、希釈量DAが多い場合にはブローバイガス中の燃料濃度が高くなりやすいために生じる。燃料カット処理の実行中にブローバイガス中の燃料濃度が高くなりやすいと、触媒39が過昇温しやすく、触媒温度TCは、高くなりやすい。
