PROBLEM TO BE SOLVED: To provide a control device capable of preventing sudden increase of a NO<SB>X</SB>generation amount without executing lean combustion at desired lean air-fuel ratio after shift-up of an automatic transmission in a supercharging region in an internal combustion engine which is equipped with a turbocharger and which executes lean combustion at desired air-fuel ratio. SOLUTION: The control device prohibits the shift-up of an automatic transmission (Step 104) when a throttle valve opening is a set value or more (Step 102) and supercharging pressure by a turbocharger is a set value or less (Step 103).
