A method (200) for ascertaining an air volume provided by means of an electric air pump (134) in an exhaust system (120) of an internal combustion engine (110), including detecting at least one activation parameter (5) of the air pump and ascertaining (220) a provided air mass flow rate (8) on the basis of a calculation specification from the at least one activation parameter (5) by utilizing an inertia of the air pump (134) and/or an inertia of the air upstream and/or downstream from the air pump (134) and/or a differential pressure from upstream from the air pump to downstream from the air pump. In addition, a processing unit and a computer program for carrying out a method (200) of this type is provided.
The method (200) for ascertaining an air volume provided by means of an electric air pump (134) in an exhaust system (120) of an internal combustion engine (110), the method comprising:
A computer configured to ascertain an air volume provided by means of an electric air pump (134) in an exhaust system (120) of an internal combustion engine (110), by:
A non-transitory computer-readable medium containing instructions that when executed by a computer cause the computer to ascertain an air volume provided by means of an electric air pump (134) in an exhaust system (120) of an internal combustion engine (110), by:
