Abstract

A method and a device for controlling an internal combustion engine, in which a first quantity characterizing the flow resistance of a first component of the exhaust-gas treatment system is determined based on a first measured quantity and a volumetric-flow quantity, and the volumetric-flow quantity is determined based on a second quantity which characterizes the flow resistance of a second component of the exhaust system.
