Abstract
A method is proposed for regulating a fill level of an exhaust component storage of a catalyst () of an internal combustion engine (), wherein the regulating of the fill level is done by using a system model (), comprising a catalyst model (), and wherein uncertainties of measured or model variables influencing the regulating of the fill level are corrected by an adaptation, which is based on signals of an exhaust gas probe () arranged at the outlet side of the catalyst (). The method is characterized in that the adaptation takes multiple pathways (), wherein signals from different signal regions () of the exhaust gas probe () situated at the outlet side are processed on different pathways. An independent claim is addressed to a controller designed to carry out the method.
