Abstract:
A method for operating an internal combustion engine of a motor vehicle, comprising a fuel pump (3), a pressure reservoir (9) and a control device (14) including a program map (15) for generating a map-dependent signal for the fuel pump, wherein fuel is supplied by the fuel pump into the pressure reservoir (9), and wherein the delivery quantity of the fuel pump (3) can be changed, and the fuel quantity delivered to the pressure reservoir (9) is adjusted to a required fuel quantity by influencing the delivery quantity of the fuel pump (3), the delivery quantity of the fuel pump (3) being controlled via the program map (15) as a function of a number of input variables received by the program map to generate the map-dependent signal as an input signal of the fuel pump, wherein the program map is equalized during a startup of the engine when the speed (nM) of the engine is lower than a predetermined threshold value (ns).
