Abstract

A method for operating an exhaust gas treatment system that includes an SCR catalytic converter is provided. Either a model-based filling level regulation for achieving the target filling level or a model-based efficiency control for achieving the target efficiency is performed according to presettable values for certain operating variables such as a temperature of the exhaust gas or of the SCR catalytic converter.
