Abstract:
1. A method for controlling an internal combustion engine, comprising: adapting a first actuating variable of at least one first actuating element based on a comparison of a first cylinder-specific variable characterizing a combustion process in at least one cylinder with a corresponding setpoint, wherein the first cylinder-specific variable is determined on the basis of an output signal of one of a structure-borne noise sensor and a combustion-chamber pressure sensor, wherein the adapting of the first actuating variable adapts the combustion process in the first cylinder; ascertaining at least one deviation value for at least one additional cylinder relative to the at least one cylinder on the basis of at least one second variable; and adapting a second actuating variable of a second actuating element on the basis of the at least one deviation value, wherein the adapting of the second actuating variable adapts a second combustion process in the second cylinder based on the deviation of the second cylinder relative to the first cylinder having the combustion process adapted on the basis of the output signal of one of the structure-borne noise sensor and the combustion-chamber pressure sensor.
