Abstract

A method and device for controlling an internal combustion engine in which a first variable characterizing the pressure in the combustion chamber of at least one cylinder in the internal combustion engine is detected by at least one sensor. A second variable is determined on the basis of the first variable. Features which are assigned to different partial injections are obtained by forming the difference within the second variable.
