Abstract

Bei einem Verfahren zur Steuerung der Einspritzmenge in eine Brennkraftmaschine bei Kraftfahrzeugen mittels eines in einem elektronischen Steuergerät fest abgespeicherten Basis-Ansteuerwertes und mittels eines durch das elektronische Steuergerät flexibel bestimmbaren Korrektur-Ansteuerwertes wird der Korrektur-Ansteuerwert in Abhängigkeit von einem während des Fahrzeug-Produktionsprozesses für einen vorgegebenen Betriebszustand der Brennkraftmaschine ermittelten Abweichwert bestimmt.In a method for controlling the injection quantity in an internal combustion engine in motor vehicles by means of an electronic control unit permanently stored basic control value and by means of a the electronic control unit flexibly determinable correction control value the correction control value is dependent on a while the vehicle production process for a given operating state the deviation value determined in the internal combustion engine.

Vorzugsweise wird der Korrektur-Ansteuerwert zusätzlich in Abhängigkeit vom momentanen Lastzustand der Brennkraftmaschine vorgegeben und/oder in Abhängigkeit vom Typ der Brennkraftmaschine bestimmt.

Figure 00000001
The correction control value is preferably additionally specified as a function of the current load state of the internal combustion engine and / or determined as a function of the type of internal combustion engine.
