Abstract
Description
図1に示すように、車両100は、火花点火式の内燃機関10を備えている。車両100は、電動機及び発電機の双方の機能を兼ね備える2つのモータジェネレータである、第1モータジェネレータ71及び第2モータジェネレータ72を備えている。したがって、車両100は、いわゆるハイブリッド車両である。
第1遊星ギア機構40は、サンギア41、リングギア42、複数のピニオンギア43、及びキャリア44を備えている。サンギア41は、外歯歯車である。サンギア41は、第1モータジェネレータ71に接続されている。リングギア42は、内歯歯車であり、サンギア41と同軸上に配置されている。ピニオンギア43は、サンギア41とリングギア42との間に複数配置されている。各ピニオンギア43は、サンギア41及びリングギア42の双方に噛み合っている。キャリア44は、自転及び公転が自在な状態でピニオンギア43を支持している。キャリア44は、クランクシャフト12に接続されている。
式(1):充電率SOC[%]=バッテリの残容量[Ah]/バッテリの満充電容量[Ah]×100[%]
バッテリ75の充電率SOCは、充電率上限値SOCHと充電率下限値SOCLとの間の範囲の値になるように、制御部210によりバッテリ75の充電制御が実行される。充電制御については後述する。充電率上限値SOCHとしては、例えば60%である。また、充電率下限値SOCLは、内燃機関10の運転状態に応じて設定部230により設定される。なお、取得部220は、取得したバッテリ温TBを一定期間に亘って記憶している。
制御部210は、アクセル操作量ACP及び車速SPに基づいて、車両100が走行するために必要な要求値である車両要求出力を算出する。制御部210は、車両要求出力や充電率SOCなどに応じて、内燃機関10、第1モータジェネレータ71、及び第2モータジェネレータ72のトルク配分を決定する。制御部210は、内燃機関10、第1モータジェネレータ71、及び第2モータジェネレータ72のトルク配分に基づいて、内燃機関10の出力と、第1モータジェネレータ71及び第2モータジェネレータ72の力行/回生とを制御する。
上述したとおり、ステップS12において、設定部230は、PM堆積量PSが予め定められた判定値以上であると判定した場合(S12:YES)、処理をステップS13に進める。
上述したとおり、ステップS22において、設定部230は、バッテリ温TBが予め定められた基準温度以下であると判定した場合(S21:YES)、処理をステップS23に進める。
(1)内燃機関10の暖機期間において充電制御が実行されることが抑制されることによって、図4(e)に示すように、内燃機関10の暖機期間において、内燃機関10の気筒11から単位時間当たりに排出される粒子状物質の量が多くなることを抑制できる。
・上記実施形態において、通常時設定制御は変更できる。例えば、ステップS13における第2下限値Bの補正処理は変更してもよい。具体例としては、設定部230は、バッテリ温TBが予め定められた判定温度以下であるか否かを判定する。そして、設定部230は、バッテリ温TBが予め定められた判定温度以下である場合、第2下限値Bの初期値から予め定められた一定値だけ加算した値を、補正後の第2下限値Bとして算出してもよい。
・さらに、例えば、ステップS22の処理を省略してもよい。この場合、設定部230は、バッテリ温TBに基づいて第1下限値Aを補正すればよい。そして、設定部230は、充電率下限値SOCLとして、常に補正後の第1下限値Aを設定すればよい。なお、この構成では、ステップS26の処理を省略できる。
