Abstract

When a required pressure ratio RP* is less than or equal to a calculation switching pressure ratio RPwot, an engine control unit calculates, as a target opening degree TA*, a throttle opening degree TA at which a throttle upstream-downstream pressure ratio RP is the required pressure ratio RP*. When the required pressure ratio RP* exceeds the calculation switching pressure ratio RPwot, the engine control unit obtains a switching point opening degree TAwot, a switching point load factor KLwot and a maximum load factor KLmax, and calculates the target opening degree TA* as a value that has a linear relationship with the required load factor KL* between the switching point opening degree TAwot and the maximum opening degree TAmax.
