Abstract
A wastegate valve is arranged in a communication passage that bypasses the exhaust turbine of a turbocharger arranged in the exhaust passage of an internal combustion engine. When the opening degree of the wastegate valve is controlled to the fully closed opening degree, a determination value is calculated based on the operation state of the internal combustion engine, and the turbo rotation speed is detected. When the turbo rotation speed is less than the determination value, a drive force is increased in the direction for closing the wastegate valve.
