Abstract

A device and a method for controlling an internal combustion engine, where a first variable characterizing the pressure in the combustion chamber of at least one cylinder of the internal combustion engine is measured by at least one sensor. A second variable characterizing the energy released during the combustion is ascertained from the first variable. When a threshold value of the second variable is exceeded, a third variable characterizing the combustion process is detected.
