Patent ID: 7203591

Claim:
A method for controlling an internal combustion engine, comprising: assigning each cylinder of the internal combustion engine at least one system deviation and at least one controller, each controller specifying a cylinder-specific control signal on the basis of the assigned system deviation, providing at least one first controller that specifies a control signal as a function of at least one signal characterizing a rotational speed of the internal combustion engine; providing at least one second controller that specifies the control signal as a function of at least one signal characterizing an exhaust-gas composition; as a function of at least one performance quantity characterizing an operating state of the internal combustion engine, specifying the control signal by one of a first group and a second group, the first group including the at least one first controller and the at least one second controller, and the second group including 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.
