Control device for internal combustion engine and a continuously

A control device for an internal combustion engine and a continuous variable transmission which enables well-responsible transmission control to be carried out at a proper transmission rate without increasing the transmission shock. When engine power corresponding to an engine power torque corrected amount is changeable, then an intake air flow adjusting unit is controlled in response to a corrected engine power torque corrected amount. On the contrary, when the corrected engine power torque corrected amount is not changeable, the amount corrected engine power torque corrected is restricted within a range where the engine power can be changed.
