Abstract
A method () for ascertaining a catalytic converter state is proposed, wherein an exhaust-gas catalytic converter () is monitored on the basis of a catalytic converter model. Here, the catalytic converter model is adapted () in a manner dependent on measured values detected by means of one or more sensors (), wherein a frequency and/or a degree of the adaptation of the catalytic converter model is detected (). The catalytic converter state is ascertained () as non-critical if the frequency and/or the degree of the adaptation do not exceed a predeterminable threshold value or is ascertained () as critical if the frequency and/or the degree of the adaptation exceed the predeterminable threshold value.
