Abstract
A method for operating an injection system has the following steps: determining, based on a pilot control characteristic, a prefeed value depending on an internal combustion engine operating parameter; initializing a correction value for the prefeed pump by a safety value predetermined for compensating deviations from a predetermined delivery behavior of the prefeed pump, which deviations lie within a predetermined tolerance range, for guaranteeing a sufficient pump delivery rate; controlling the prefeed pump depending on the prefeed and the correction values; adapting the correction value effecting the delivery behavior of the prefeed pump depending on a variable of the system the value or value curve of which indicates that a desired pressure can be generated in the fuel accumulator, namely in the sense of reducing the delivery output of the prefeed pump, as long as the value indicates that the desired pressure can be generated in the fuel accumulator.
