CONTROL DEVICE FOR INTERNAL COMBUSTION ENGINE

摘要

Provided is a control device for an internal combustion engine, which can properly reflect various requests for the performance of the internal combustion engine in the target value of the control amount, each of the requests not being required to be expressed in the form of the request value of the control amount. The control device for the internal combustion engine acquires various requests for the performance of the internal combustion engine, and provides a constraint corresponding to each of the requests for the value of the control amount. More specifically, the constraint provided for the value of the control amount is expressed as a set of constraint index values assigned to respective values of the control amount, and the distribution of constraint index values assigned to the respective values of the control amount is varied according to the type of the request. The control device integrates the constraint index values, which are assigned to the respective values of the control amount for every request, with respect to each value of the control amount. The control device determines the limitation of the control amount defined by the upper limit and the lower limit, on the basis of the distribution of the integrated constraint index values for the control amount. The control device determines the target value of the control amount within the determined limitation.
