Abstract

A method for controlling boost pressure in an internal combustion engine is provided. The method includes a boost pressure control device, which is used to control the boost pressure in an internal combustion engine. The boost pressure control device includes a bypass unit, preferably in the exhaust gas flow of the internal combustion engine. The bypass unit includes an actuating device which enables the bypass unit when a predetermined actuating device setpoint value is reached. An adapted value is established as the correction value (pwgad) as a function of preset and/or detected internal combustion engine parameters (rlsol, nmot). The adapted value is used to adapt the setpoint value for the actuating device, which is specified as a function of the operating point, for a predetermined control deviation between a boost pressure actual value and a boost pressure setpoint value.
