Abstract
A method for ascertaining fill levels of first and second exhaust gas catalytic converters in an exhaust gas system downstream from an internal combustion engine with respect to at least one exhaust gas component. The method includes detecting, using a sensor upstream from the first exhaust gas catalytic converter, at least one operating parameter of the exhaust gas system, ascertaining the fill level of the first exhaust gas catalytic converter based on the detected at least one operating parameter using a first calculation rule, ascertaining a total fill level of the first exhaust gas catalytic converter and second exhaust gas catalytic converter based on the ascertained at least one operating parameter using a second calculation rule, and ascertaining the fill level of the second exhaust gas catalytic converter as a difference between the total fill level and the fill level of the first exhaust gas catalytic converter.
