Description
次に、「WSC走行モード」の詳細について説明する。「WSC走行モード」とは、エンジンEが作動した状態を維持している点に特徴があり、ドライバ要求トルク変化に対する応答性が高い。具体的には、第1クラッチCL1を完全締結し、第2クラッチCL2をドライバ要求トルクに応じた伝達トルク容量TCL2としてスリップ制御し、エンジンE及び/又はモータジェネレータMGの駆動力を用いて走行する。
次に、MWSC走行モード領域を設定した理由について説明する。推定勾配が所定勾配(g1もしくはg2)より大きいときに、例えば、ブレーキペダル操作を行うことなく車両を停止状態もしくは微速発進状態に維持しようとすると、平坦路に比べて大きな駆動力が要求される。自車両の荷重負荷に対抗する必要があるからである。
