Abstract
A method for operating an internal combustion engine having at least two exhaust-gas turbochargers, which allows the synchronous operation of the two exhaust-gas turbochargers to be reliably set (adjusted). For each of the at least two exhaust-gas turbochargers, an actuator for controlling the boost pressure produced by the compressors of the at least two exhaust-gas turbochargers is controlled by a separate control signal. At least one of the control signals is corrected in an open-loop-controlled manner for the purpose of synchronizing the at least two exhaust-gas turbochargers.
