To prevent an engine rotation speed from being put into a high rotational state while suppressing reduction in power performance by reduction in an output torque of an engine.SOLUTION: When a supercharging pressure Pchg by a supercharger 18 is high, since an allowable maximum rotation speed Nemax is set at a low value compared to the case in which it is low, an engine torque Te is reduced with a comparatively low engine rotation speed Ne, and the engine rotation speed Ne is hardly put into a high rotational state. In addition, when the supercharging pressure Pchg is comparatively low and the engine rotation speed Ne is hardly put into the high rotational state, the allowable maximum rotation speed Nemax is set at a comparatively high value, the engine torque Te is not reduced to the comparatively high engine rotation speed Ne, and power performance is easily secured. Therefore, the engine rotation speed Ne can be prevented from being put into a high rotational state while suppressing reduction in power performance by reduction in the engine torque Te.SELECTED DRAWING: Figure 9

    【課題】エンジンの出力トルクの低減による動力性能の低下を抑制しつつ、エンジンの回転速度が高回転状態に陥るのを抑制する。【解決手段】過給機18による過給圧Pchgが高いときには、低いときに比べて、許容最大回転速度Nemaxが低い値に設定されるので、比較的低いエンジン回転速度NeでエンジントルクTeが低減され、エンジン回転速度Neが高回転状態となり難くされる。又、過給圧Pchgが比較的低く、エンジン回転速度Neが高回転状態になり難いときには、許容最大回転速度Nemaxが比較的高い値に設定されるので、比較的高いエンジン回転速度NeまでエンジントルクTeが低減されず、動力性能が確保され易くされる。よって、エンジントルクTeの低減による動力性能の低下を抑制しつつ、エンジン回転速度Neが高回転状態に陥るのを抑制することができる。【選択図】図9
