ABSTRACT:
A method for controlling an internal combustion engine in which each cylinder of the internal combustion engine is assigned at least one system deviation and at least one controller, each controller predefining a cylinder-specific control signal on the basis of the assigned system deviation, is characterized in that at least one first controller which predefines the control signal as a function of at least one signal characterizing the rotational speed of the internal combustion engine is provided, and at least one second controller which predefines the control signal as a function of at least one signal characterizing the exhaust-gas composition is provided; and, as a function of at least one operating parameter characterizing the operating state of the internal combustion engine, the control signal is predefined either by the at least one first or the at least one second controller or by a combination of a control signal generated by the at least one first controller and a control signal generated by the at least one second controller.
