Abstract
A method and a control device for regulating a modeled fill level of an exhaust gas component reservoir of a catalytic converter of an internal combustion engine. Regulation of the modeled fill level is accomplished using a system model. An actual maximum storage capacity of the catalytic converter for the exhaust gas component is ascertained during operation of the internal combustion engine and is taken into consideration in regulating the modeled fill level.

A method for regulating a modeled fill level of an exhaust gas component reservoir of a catalytic converter of an internal combustion engine, the method comprising the following steps:
- regulating the modeled fill level using a system model;
- and
- ascertaining, during operation of the internal combustion engine, an actual maximum storage capacity of the catalytic converter for the exhaust gas component, wherein the ascertained actual maximum storage capacity is taken into consideration in regulating the modeled fill level.
A control device configured to regulate a modeled fill level of an exhaust gas component reservoir of a catalytic converter of an internal combustion engine, the control device configured to regulate the modeled fill level using a system model, wherein the control device is configured to ascertain an actual maximum storage capacity of the catalytic converter for the exhaust gas component during operation of the internal combustion engine and to take the ascertained actual maximum storage capacity into consideration in the regulating of the modeled fill level.
