Abstract

A method and a device are described for controlling an internal combustion engine. A manipulated variable is specifiable on the basis of at least one measured quantity. The measured quantity is filterable by at least one filter. An excitation variable is superimposed on the manipulated variable, and the properties of the filter are determined on the basis of the resulting reaction of the measured quantity.
