Abstract

A device and a method for controlling an internal combustion engine are provided, in which a first actuating variable of at least one first actuating element is adapted on the basis of a comparison between a first cylinder-specific variable characterizing the combustion process in at least one cylinder and a setpoint value for this variable. On the basis of at least one second variable, at least one deviation value for at least one additional cylinder is determined. Based on this deviation value, a second actuating variable of a second actuating element is adapted.
