Abstract
A control apparatus of an internal combustion engine capable of appropriately reflecting various requests relating to the performance of the internal combustion engine. Specifically, the control device of the internal combustion engine acquires various requests relating to the performance of the internal combustion engine, and sets restricted ranges of the value of the control variable in accordance with the details of the requests. At this moment, the control device temporally changes the set restricted ranges for specific requests associated with the time integral value of the control variable rather than the instantaneous value of the control variable. Subsequently, the control device determines a final restricted range on the basis of the overlap between the restricted ranges set for each request, and determines the target value of the control variable in the final restricted range.
