Abstract (en)

[origin: WO2011154229A1] A method for operating an internal combustion engine, in particular for avoiding undesired pressure deviations, is described. A setpoint value (108) of a pressure is determined as a function of a driver's request. An actual value (1 10) of the pressure is compared with the setpoint value (108) of the pressure. An actuation signal (106) which results therefrom is fed to a controlled section (44). The actual value (1 10) of the pressure is determined from the controlled section (44). A change in the driver's request is detected. A pressure correction value (104) is determined as a consequence of the change in the driver's request. The actuation signal (108) is changed as a function of the pressure correction value (104).
