  • Patent number: 11933234
    Abstract: An engine is provided with a turbo charger including a wastegate valve. A first setpoint of opening of the wastegate valve is set in accordance with a target boost pressure. While a difference between the target boost pressure and a real boost pressure is large, the opening is controlled to a second setpoint, wherein the second setpoint is smaller than the first setpoint. While the opening is controlled to the second setpoint, it is determined whether a condition for limitation is satisfied in which an intake air quantity is above an intake air quantity criterion and an engine rotation speed is above an engine rotation speed criterion. When the condition is satisfied, the opening is controlled in a direction to increase from the second setpoint. The engine rotation speed criterion decreases as the intake air quantity increases. The intake air quantity criterion decreases as the engine rotation speed increases.
