PROBLEM TO BE SOLVED: To avoid the abrupt lowering of motor rotation when restoring engine torque and motor torque at an upstream side of a second clutch which are lowered for preventing the overheat of the second clutch.SOLUTION: The overheat of a second clutch is prevented by lowering engine torque Te and the motor torque Tm of a motor/generator more than those at an instantaneous time t1 at which the overheat of the second clutch is predicted, and when the engine torque Te and the motor torque Tm are raised and restored from those at an instantaneous time t2 at which the overheat of the second clutch becomes not to be predicted, a rise restoration speed δ of the motor torque is set higher than a rise restoration speed β of the engine torque Te.SELECTED DRAWING: Figure 2

    【課題】第2クラッチの過熱防止用に低下させた上流側のエンジントルクおよびモータトルクを復帰させる時、モータ回転が急低下することのないようにする。【解決手段】第2クラッチの過熱が予見される瞬時t1より、エンジントルクTeを低下させると共に、モータ/ジェネレータのモータトルクTmを低下させて第2クラッチの過熱を防止し、第2クラッチの過熱が予見されなくなった瞬時t2よりエンジントルクTeおよびモータトルクTmを上昇復帰させるに当たり、エンジントルクTeの上昇復帰速度βよりもモータトルクの上昇復帰速度δを高く設定する。【選択図】図2
