To suppress delay in detecting output torque of an engine when supercharging pressure is set high or when supercharging pressure is greatly changed, while suppressing deterioration in robustness when detecting output torque of the engine having a supercharger.SOLUTION: When weighting is performed on a series of sequentially calculated/estimated engine torque Tees(n) calculated based on sequentially obtained MG1 torque Tg(n) to calculate estimated engine torque Tees, a weight coefficient Wx is set so that degrees of relaxation of change in the estimated engine torque Tees is smaller when supercharging pressure Pchg is high than when the pressure is low or is smaller when change in the supercharging pressure Pchg is large than when the change is small, so that robustness can be obtained by performing weighting on the series of sequentially calculated/estimated engine torque Tees(n) and the sequentially calculated/estimated engine torque Tees(n) can be easily reflected on the estimated engine torque Tees, when the supercharging pressure is greatly changed.SELECTED DRAWING: Figure 9

    【課題】過給機を有するエンジンの出力トルクを検出する際のロバスト性の悪化を抑制しつつ、過給圧が高くされたとき又は過給圧が大きく変化させられたときのエンジンの出力トルクの検出遅れを抑制する。【解決手段】逐次取得MG1トルクTg(n)に基づいて算出された一連の逐次算出推定エンジントルクTees(n)に重み付けが行われて推定エンジントルクTeesが算出されるに際して、過給圧Pchgが高いときには低いときに比べて又は過給圧Pchgの変化が大きいときには小さいときに比べて推定エンジントルクTeesの変化の緩和度合が小さくなるように重み係数Wxが設定されるので、一連の逐次算出推定エンジントルクTees(n)に対する重み付けによりロバスト性が得られつつ、大きく変化させられたときの逐次算出推定エンジントルクTees(n)が推定エンジントルクTeesに反映され易くされる。【選択図】図9
