Abstract
In a method for regulating a boost pressure of an engine which has a compressor, an actual boost pressure and a setpoint boost pressure are used as input parameters. The setpoint boost pressure is regulated in such a way that a pressure ratio in the compressor does not exceed a limit pressure ratio. A reference boost pressure is ascertained based on a speed of the engine and a load of the engine. A flow and/or a pressure of air supplied to the engine is/are detected and an associated flow signal and/or pressure signal is generated. The smaller of the reference boost pressure and a limit boost pressure is used as a setpoint boost pressure. The limit boost pressure is ascertained based on a limit boost pressure ratio and a speed of the compressor.
