Abstract

A method and an apparatus for controlling an internal combustion engine are described. At least one sensor serves to detect a first variable that characterizes the pressure in the combustion chamber of at least one cylinder. A second variable, which characterizes the maximum value of the change and/or the location of the maximum value of the change, is determined on the basis of this first variable. This second variable serves to control operating parameters of the internal combustion engine in an open-loop and/or a closed-loop manner.
