Zusammenfassung:	A method and apparatus regulates the pressure in the intake duct of an internal combustion engine. The internal combustion engine has a control unit, in which a desired pressure value is determined. The current pressure in the intake duct is adjusted to the desired value by a valve device, and the valve device is acted upon by an actuating signal from the control unit. In order to build up the pressure in the intake duct with a suitable dynamic response for each load state, particularly when using a number of valve devices, the actuating signal is used as a control signal, as a function of a relative desired pressure valve, from a control characteristic map stored in the control unit. A controller signal produced in a controller is superimposed on the control signal if required.
