Abstract

A method for the model-based open-loop and closed-loop control of an internal combustion engine includes the steps of: during stationary operation, switching takes place cyclically from the normal operation to an exploration operation, wherein in the exploration operation, an exploration measure of quality (J/EXP) is calculated in accordance with combustion model and variance (VAR) thereof, wherein the exploration measure of quality (J/EXP) is set as essential for the operating point of the internal combustion engine, wherein on the basis of the operating variables of the internal combustion engine combustion model is adapted, and wherein switching back to normal operation takes place.
