The invention relates to an internal combustion engine comprising a fuel supplying device. Said fuel supplying device comprises a low-pressure circuit provided with a low-pressure pump and a high-pressure pump that is coupled to the low-pressure circuit on the input side and transports fuel into a fuel accumulator. A fuel transporting flow of the low-pressure pump is corrected according to an actual and a previously pre-determined nominal value of the fuel pressure in the fuel accumulator.

The invention claimed is: 1. A method for controlling an internal combustion engine having a fuel delivery device, comprising: providing a low-pressure circuit with a low-pressure pump; and coupling a high-pressure pump on an input side to the low-pressure circuit where the high-pressure pump delivers fuel to a fuel accumulator, wherein a fuel delivery flow of the low-pressure pump is corrected as a function of a current and a preceding predetermined setpoint value of the fuel pressure in the fuel accumulator. 2. The method as claimed in claim 1, wherein correction of the fuel delivery flow of the low-pressure pump is activated as a function of the current and the preceding predetermined setpoint values of the fuel pressure in the fuel accumulator. 3. The method as claimed in claim 2, wherein a first correction value is determined, when correction to the fuel delivery flow of the low-pressure pump is activated, as a function of a current and a preceding quantity, the quantity being representative of a fuel delivery flow Of the high-pressure pump, which fuel delivery flow is set in each case as a function of the current predetermined setpoint value of the fuel pressure in the fuel accumulator, and wherein the fuel delivery flow of the low-pressure pump is corrected as a function of the first correction value. 4. The method as claimed in claim 3, wherein the first correction value is assigned a neutral value after a predetermined interval immediately following the activation of correction to the fuel delivery flow of the low-pressure pump. 5. The method as claimed in claim 4, wherein a current second correction value is determined which is equal to the first correction value, while correction of the fuel delivery flow of the low-pressure pump is activated, and which is dependent on a difference between the preceding second correction value and a reset value, when correction of the fuel delivery flow of the low-pressure pump is not activated, until the current second correction value has a neutral value, and wherein the fuel delivery flow of the low-pressure pump is corrected as a function of the second correction value. 6. The method as claimed in claim 2, wherein a third correction value is determined, when correction to the fuel delivery flow of the low-pressure pump is activated, as a function of the current and the preceding predetermined setpoint value of the fuel pressure in the fuel accumulator, and wherein the fuel delivery flow of the low-pressure pump is corrected as a function of the third correction value. 7. The method as claimed in claim 6, wherein the third correction value is determined from an engine operating map. 8. A device for controlling an internal combustion engine with the aid of a fuel delivery device, comprising: a low-pressure circuit having a low-pressure pump, and a high-pressure pump coupled on the input side to the low-pressure circuit and to a fuel accumulator on an output side where an output flow is delivered to the accumulator; and a fuel delivery flow correction device that corrects a fuel delivery flow of the low-pressure pump as a function of a current and a preceding predetermined setpoint value for the fuel pressure in the fuel accumulator. 9. The device as claimed in claim 8, wherein correction of the fuel delivery flow of the low-pressure pump is activated as a function of the current and the preceding predetermined setpoint values of the fuel pressure in the fuel accumulator. 10. The device as claimed in claim 9, wherein a first correction value is determined, when correction to the fuel delivery flow of the low-pressure pump is activated, as a function of a current and a preceding quantity, the quantity being representative of a fuel delivery flow of the high-pressure pump, which fuel delivery flow is set in each case as a function of the current predetermined setpoint value of the fuel pressure in the fuel accumulator, and wherein the fuel delivery flow of the low-pressure pump is corrected as a function of the first correction value. 11. The device as claimed in claim 10, wherein the first correction value is assigned a neutral value after a predetermined interval immediately following the activation of correction to the fuel delivery flow of the low-pressure pump. 12. The method as claimed in claim 11, wherein a current second correction value is determined which is equal to the first correction value, while correction of the fuel delivery flow of the low-pressure pump is activated, and which is dependent on a difference between the preceding second correction value and a reset value, when correction of the fuel delivery flow of the low-pressure pump is not activated, until the current second correction value has a neutral value, and wherein the fuel delivery flow of the low-pressure pump is corrected as a function of the second correction value. 13. The method as claimed in claim 9, wherein a third correction value is determined, when correction to the fuel delivery flow of the low-pressure pump is activated, as a function of the current and the preceding predetermined setpoint value of the fuel pressure in the fuel accumulator, and wherein the fuel delivery flow of the low-pressure pump is corrected as a function of the third correction value. 14. The method as claimed in claim 13, wherein the third correction value is determined from an engine operating map.
