Abstract:
1. A method for regulating a charge pressure of an internal combustion engine having at least two exhaust-gas turbochargers, comprising: providing a first actuating element for setting a charge pressure of a first exhaust-gas turbocharger; providing a second actuating element for setting a charge pressure of a second exhaust gas turbocharger; and determining, dependent on an exhaust-gas back pressure prevailing in an exhaust-gas channel at an output of the internal combustion engine, a first controlled variable for the first actuating element and a second controlled variable for the second actuating element, wherein the first controlled variable and the second controlled variable are determined as a function of one and the same exhaust-gas back pressure prevailing in the exhaust-gas channel at the output of the internal combustion engine.
