ABSTRACT:
A method for approximating a stored pilot control map of a pressure control valve of a common-rail pump to the effective of pilot control map of the pressure control valve is presented. The stored pilot control map forms a desired pressure in the rail on a control current of the pressure control valve. The method includes the following method steps a) measurement of the pressure in the rail; b) determination of the control current of the pressure control valve; and c) adaptation of the stored pilot control map by a regression process that includes the pressure measured in step a) and control current measured in step b). In the course of a test run lasting 120 seconds (s) the control deviations (dp) of the desired pressure from the actual pressure in the pressure control valve could be substantially reduced.
