Abstract
A method for controlling an SCR catalytic converter (), comprising detecting () concentration values () in the exhaust gas downstream of the catalytic converter (), wherein at least one concentration value for NHand one concentration value for NOis detected; calculating () modeled concentration values () for NHand NOdownstream of the catalytic converter on the basis of a catalytic converter model, wherein the model comprises an aging parameter () which at least partially describes aging of the modeled catalytic converter; comparing () the detected concentration values with the modeled concentration values; and, in a manner dependent on the result of the comparison, changing the aging parameter () of the model and/or changing a predefined dosing quantity for a reducing agent in the SCR catalytic converter.
