PROBLEM TO BE SOLVED: To easily determine which of a waist gate valve 47 and a waist gate valve opening sensor 47b gets out of order without providing any special circuit when a detection value of the waist gate valve opening sensor 47b does not change.SOLUTION: When the opening of a waist gate valve 47 detected by a waist gate valve opening sensor 47b does not change, it is determined which of the waist gate valve 47 and waist gate valve opening sensor 47b gets out of order based upon whether the opening of the waist gate valve 47 detected by the waist gate valve opening sensor 47b is larger or smaller than a target opening, a feedback quantity of first feedback control based upon actual boost pressure and target boost pressure, and a feedback quantity of second feedback control based upon the opening detected by the waist gate valve opening sensor 47b and the target opening. |
