Abstract
A control device acquires various requests concerning the performance of an internal combustion engine and sets a request-specific constraint on a control amount value. The constraint is expressed as a set of constraint index values assigned to individual control amount values, and the distribution of the constraint index values is varied in accordance with the type of a request. The control device integrates the constraint index values for each control amount value and then, in accordance with the distribution of the integrated constraint index value for a control amount, determines a limitation of the control amount. The control device determines a target control amount value within the limitation and controls the internal combustion engine in accordance with the target control amount.
