Abstract

A method for a model-based open-loop and closed-loop control of an internal combustion engine includes the steps of: calculating, by an optimizer, a pre-optimized quality measure based on an operating situation, wherein, in calculating the pre-optimized quality measure, a plurality of discrete manipulated variables having a plurality of discrete settings are interpreted as a plurality of continuous manipulated variables having a continuous settings range; quantizing the plurality of continuous manipulated variables, and the plurality of continuous manipulated variables are set as a plurality of new discrete manipulated variables (SG(new)) having a plurality of discrete settings; and calculating, by the optimizer, a post-optimized quality measure based on the plurality of new discrete manipulated variables and the operating situation of the internal combustion engine, and the post-optimized quality measure is set as critical for an operating point of the internal combustion engine by the optimizer.
