Abstract
The present invention is a proposal relating to cooperative manipulation of an actuator which actively changes a supercharging pressure and a throttle in the case of application of torque demand control to an internal combustion engine with a supercharger. A control device provided by the present invention separately determines a target air quantity for manipulation of the throttle, and a target air quantity for manipulation of the actuator. In more detail, driver required torque which is included in required torque is converted into an air quantity in accordance with a predetermined conversion rule, and the air quantity which is obtained by the conversion is determined by calculation as a reference target air quantity. The reference target air quantity is used as a target air quantity for throttle manipulation, and is also used as a target air quantity for actuator manipulation at a normal time. When a change occurs to the required torque, and the change cannot be realized under the reference target air quantity, a correction target air quantity capable of realizing the change is determined by calculation, and is used as the target air quantity for throttle manipulation.
