Abstract
A method for compensating for mismatches of the precontrol of a fuel metering for an internal combustion engine. A regulation being superimposed on the precontrol. At least one correction quantity being formed, from the behavior of the regulation at high temperatures of the internal combustion engine, which influences the fuel metering even at low temperatures of the internal combustion engine in a supplementing manner to the superimposed regulation for compensating for the mismatches. At low temperatures a further correction quantity is formed which acts upon the fuel metering, whose effect at low temperatures of the internal combustion engine is greater than at high temperatures.
