Abstract:
To suppress a deviation between an actual opening degree of a waste gate valve and a target opening degree thereof.SOLUTION: Control includes: obtaining, once in a given period, a first correction amount that is a deviation of a reference position that is a rotation angle of an actuator when a waste gate valve is at a given angle; obtaining a second correction amount that is a deviation amount of the reference position, every time an engine is operated at a high load than when the first correction amount has been obtained; and controlling the actuator so that a controlling actual opening degree is equal to the target opening degree, where the controlling actual opening degree is obtained by correcting an opening degree of the waste gate valve based on a detected rotation angle with the first correction amount and the second correction amount.SELECTED DRAWING: Figure 5
