Abstract
In a method for adaptation of closed-loop control of a pressure in a common-rail injection system () for an internal combustion engine (), with the closed-loop control having a pilot control and the common-rail injection system () with at least a correction device () able to corrected by corrective signals in each case corresponding to corrective values for influencing the pressure, a pilot control value for generating at least one corrective signal for the correction device () is determined, and using the pilot control value by generating the at least one corrective signal and issuing it to a correction device, the current pressure is corrected to a predetermined setpoint pressure. For adaptation the pilot control is adapted as a function of at least one current value of an operating parameter of the internal combustion engine () and of the corrective value corresponding to the at least one corrective signal.
