Description
本発明者らの研究によると、全体変速比が第1の所定値のときに第1のMGがモータとして動作する動力の最大値と、全体変速比が第2の所定値のときに第1のMGがモータとして動作する動力の最大値と、全体変速比が第1の所定値から第2の所定値までの範囲内で第1のMGが発電機として動作する動力の最大値とが等しくなる場合に、全体変速比の第1の所定値から第2の所定値までの範囲内で2つのMGの扱う動力の総和の最大値が最小になることが判明した。
まず、図1に基づいて車両の駆動システム全体の概略構成を説明する。
車両には、内燃機関であるエンジン10(動力源)と第1のモータジェネレータ(以下「第1のMG」と表記する)11と第2のモータジェネレータ(以下「第2のMG」と表記する)12が搭載され、更に、第1の遊星ギヤユニット13(第1の遊星歯車機構)及び第2の遊星ギヤユニット14(第2の遊星歯車機構)を有する動力伝達装置15が搭載されている。第1のMG11は、主に発電機として使用されるが、モータとしても使用される。また、第2のMG12は、主にモータとして使用されるが、発電機としても使用される。
Ts1=Te ×ρ1 /(1+ρ1 ) ……(1)
Tr1=Te /(1+ρ1 ) ……(2)
Ts2=−TC2×ρ2 /(1+ρ2 ) ……(3)
Tr2=−TC2/(1+ρ2 ) ……(4)
ρ2 =ρA ×ρB /(ρA +1)
Tm =−Tr2 ……(5)
Ts1=−Ts2−Tg ……(6)
Tp =−Tr1−TC2 ……(7)
Tp =−(ρ1 +ρ1 ×ρ2 +ρ2 )×Tm /ρ1 +Tg /ρ1 ……(8)
Te =ρ2 ×(ρ1 +1)×Tm /ρ1 −(ρ1 +1)×Tg /ρ1 ……(9)
図2の共線図に示す各部のトルクと回転速度との関係により、図5に示すように、第1のMG11の動力量(モータとして動作する場合を正の値とする)は、エンジン10の回転速度Ne (=動力入力軸25の回転速度)と動力出力軸26の回転速度Np との比である全体変速比Rall =Ne /Np の関数として表すことができる。図5の実線はエンジン10の動力が最大で主電池33の出力が0の場合の第1のMG11の動力量を示し、図5の破線はエンジン10の動力が最大で主電池33の出力が最大の場合の第1のMG11の動力量を示している。
以下、ハイブリッドECU34が実行する図7乃至図9の各ルーチンの処理内容を説明する。
図7に示すエンジン走行制御ルーチンは、エンジン10の動力を動力伝達装置15で変速して動力出力軸26に要求出力を出力する場合に所定周期で繰り返し実行される。本ルーチンが起動されると、まず、ステップ101で、車速を検出した後、ステップ102に進み、アクセル開度を検出する。
この際、第1のMG11と第2のMG12との間でエンジン10の回転速度制御の役割と動力出力軸26のトルク制御の役割を運転条件に応じて切り換える。
図8に示すモータ走行制御ルーチンは、主電池33の電力を動力伝達装置15で動力に変換して動力出力軸26に要求出力を出力する場合に所定周期で繰り返し実行される。本ルーチンが起動されると、まず、ステップ201で、車速を検出した後、ステップ202に進み、アクセル開度を検出する。
図9に示すエンジン始動時制御ルーチンは、エンジン10を始動する場合に所定周期で繰り返し実行される。本ルーチンが起動されると、まず、ステップ301で、車速を検出した後、ステップ302に進み、アクセル開度を検出する。
次に、図11乃至図17を用いて本発明の実施例2〜8を説明する。但し、前記実施例1と実質的に同一部分には同一符号を付して説明を省略又は簡略化し、主として前記実施例1と異なる部分について説明する。
