Description
まず、図1に基づいてハイブリッド車の駆動システムの概略構成を説明する。
Nmin /ρl /ρf ≦N1 ≦Nmax /ρl /ρf
Nmin /ρh /ρf ≦N2 ≦Nmax /ρh /ρf
ここで、Nmin はエンジン12の最低回転速度(例えばアイドル回転速度)であり、Nmax はエンジン12の最高回転速度である。また、ρl はローギヤ機構33のギヤ比であり、ρh はハイギヤ機構32のギヤ比であり、ρf はファイナルギヤ比である。
力行時のMG要求パワーPmgは、第1のMG13の最大トルクTmg1.max (図3参照)と、第1のMG13の回転速度Nmg1 と、第2のMG14の最大トルクTmg2.max (図3参照)と、第2のMG14の回転速度Nmg2 を用いて、下記の(1)式で表すことができる。
+y×Tmg2.max ×Nmg2 ) …(1)
ここで、xは第1のMG13のトルク負荷率、yは第2のMG14のトルク負荷率であり、ηはローギヤ機構33のギヤ効率である。
Pmg1.max =2π/60×Tmg1.max ×Nmg1 …(2)
Pmg2.max =2π/60×Tmg2.max ×Nmg2 …(3)
Pmg=η×x×Pmg1.max +y×Pmg2.max …(4)
Pmg=η×x×(1+y/a)×Pmg1.max …(5)
y(x)=−a×x+a×Pmg/(η×Pmg1.max ) …(6)
Pmg=1/η×x×Pmg1.max +y×Pmg2.max …(7)
y(x)=−a×x+a×η×Pmg/Pmg1.max …(8)
力行時のxとyの関係を表す上記(6)式を用いた場合と、回生時のxとyの関係を表す上記(8)式を用いた場合のそれぞれについて、取り得るxとyにおいて第1のMG13の損失Pmg1.loss(x×Tmg1.max ,Nmg1 )と第2のMG14の損失Pmg2.loss(y×Tmg2.max ,Nmg2 )を、MG損失のマップ(図4参照)を用いて算出する。このMG損失マップは、試験データや設計データ等に基づいて作成したものである。
Pmg.loss =Pmg1.loss(x×Tmg1.max ,Nmg1 )
+Pmg2.loss(y×Tmg2.max ,Nmg2 )
Po =2π/60×To ×Nd ×ρf
Pmg=Po
Tmg1 =xopt ×Tmg1.max
Tmg2 =y×Tmg2.max
Te =一定値
Tmg1 =Te
Tmg2 =To
これにより、エンジン12のトルクを一定に維持しながら、第2のMG14で出力軸26の要求トルクTo を実現できるようにする。
ρ=ρl
ρ=ρh
Ne =ρ×ρf ×Nd
Pe =2π/60×Te ×Ne
Pmg=Po −Pe
Tmg1 =xopt ×Tmg1.max
Tmg2 =y×Tmg2.max
