ABSTRACT:
In a case where an oscillation frequency per unit time of a first feedback amount of supercharging pressure (VNT) control exceeds a judgment value, or in a case where an oscillation frequency per unit time of a second feedback amount of exhaust gas recirculation (EGR) control exceeds a judgment value, it is determined that a target VNT opening degree or a target EGR opening degree is in a hunting state. In the case where the hunting of the target VNT opening degree or the target EGR opening degree is detected, a first or a second gain correction coefficient multiplied to the first or the second feedback amount is changed to a value to decrease an absolute value of the first or the second feedback amount.
