Abstract
【解決手段】 エンジン、少なくとも二つのモータ/ゼネレータが動力源として備えられ、前記モータ/ゼネレータに電力を供給するバッテリーを備えるハイブリッド自動車において、前記エンジンの運転点の最適トルク及び定常状態の最大トルク、前記モータ/ゼネレータの運転点の最適トルク及び定常状態の最大トルクを入力するステップと、前記エンジン及び前記モータ/ゼネレータの低減トルク比率をそれぞれ計算するステップと、前記エンジン及び前記モータ/ゼネレータの低減トルク比率を用いて、低減ファクターを設定するステップと、前記低減ファクターと、前記エンジン及び前記モータ/ゼネレータの最適トルクを用いてそれぞれの目標トルクを計算するステップと、前記それぞれの目標トルクに応じて前記エンジン及びモータ/ゼネレータのトルクを制御するステップと、を含むことを特徴とする。

Description
また、前記制御部90は、エンジン10と、第1モータ/ゼネレータ20及び第2モータ/ゼネレータ30のトルクを制御するTCU(Torque Control Unit)であってもよい。
例えば、第2モータ/ゼネレータ30のトルクが減少すると、PE(power electronics;電気系部品;バッテリー、インバータなど)のパワーの不釣り合いが発生してバッテリー60の過充電/過放電が発生する虞があり、第2モータ/ゼネレータ30の逆トルクが発生して駆動力が過多になる虞がある。
前記低減トルク比率は、運転点における最適トルク及び定常状態における最大トルクのうち小さな値を導き出して、これを運転点における最適トルクで除した値であってもよい。
