- turbo rotation speed NT is detected by the speed sensor 45 (step S14). Then, it is determined whether or not the turbo rotation speed NT is lower than a determination value J (step S15).
- step S16 a process for increasing the driving force in the valve closing direction of the waste gate valve 25 is executed (step S16). Specifically, the operation control of the electric motor 26 is executed in a manner of increasing the power supplied to the electric motor (see FIG. 2).
- step S15 when the turbo rotation speed NT is equal to or higher than the determination value J (step S15: NO), the process for increasing the driving force in the valve closing direction of the waste gate valve 25 is not executed, and the actual opening at this time VP is stored as a learning value for the fully closed opening (step S17).

When there is no exhaust leakage, an appropriate value corresponding to the amount of exhaust flowing into the exhaust turbine 23 can be calculated.
- the calculation parameters used for calculating the determination value J can be arbitrarily changed as long as they include the intake air amount GA and the fuel injection amount of the internal combustion engine 11.
