    Abstract: An anomaly determination device executes a first anomaly determination process and a second anomaly determination process. The anomaly determination device determines in the first anomaly determination process that an anomaly is present in a link mechanism when a fully-closed-time detection value is outside a closed-side normal range and when a fully-open-time detection value is outside an open-side normal range. The anomaly determination device determines in the second anomaly determination process that an anomaly is present in the link mechanism if the difference between the fully-closed-time detection value and the fully-open-time detection value is outside a normal distance range set in advance when it is not determined in the first anomaly determination process that an anomaly is present in the link mechanism.

    Abstract: A wastegate is provided in an exhaust bypass passage that allows exhaust gas to bypass a turbine wheel of an exhaust turbine-type forced-induction device. A required boost pressure is set in accordance with a running state of an engine. A controller is configured to control a drive force of the wastegate to a magnitude that achieves the required boost pressure when the required boost pressure is higher than a preset pressure, and control the drive force to a magnitude that achieves a higher boost pressure than the required boost pressure when the required boost pressure is less than or equal to the preset pressure.
