Patent ID: 8347863

Claim:
A method for controlling a fuel delivering device of an internal combustion engine, wherein the fuel delivering device has a high-pressure pump, which conveys fuel into a fuel reservoir, one or more injection valves supplied with fuel by the fuel reservoir, a fuel pressure sensor operable to detect a fuel pressure in the fuel reservoir, a volume flow control valve that is assigned to the high-pressure pump, the method comprising the steps of: determining a control difference from a difference between a predefined fuel pressure and the detected fuel pressure, feeding the control difference to a controller that comprises a proportional component that outputs a fuel mass control value and an integral component that outputs an integrated value, comparing an absolute value of the integrated value to a, predetermined threshold value during the predefined mode of operation of the internal combustion engine, if the absolute value of the integrated value exceeds the predetermined threshold value during the predefined mode of operation of the internal combustion engine, determining a corrective value for an error value of a fuel flow rate based on the integrated value multiplied by a predetermined factor and a predetermined step width factor or the integrated value multiplied with a predetermined factor that includes the step width factor, determining the total quantity of fuel to be conveyed into the fuel reservoir based on (a) a preliminary quantity of fuel to be injected into the fuel reservoir (b) the fuel mass control value, and (c) a predefined quantity of fuel to be injected by the one or more injection valves, and generating an actuating signal for the volume flow control valve based on (a) the determined total quantity of fuel to be conveyed into the fuel reservoir and (b) the determined corrective value.
