Abstract

Vorrichtung und Verfahren zur Steuerung einer Brennkraftmaschine, insbesondere einer Dieselbrennkraftmaschine, mit wenigstens einem mengenbestimmenden Stellglied. Eine erste Steuereinheit gibt abhängig von ersten Größen eine Kraftstoffmengengröße QK vor. Eine zweite Steuereinheit bestimmt ausgehend von der Kraftstoffmengengröße und weiteren Größen eine Stellgröße für das Stellglied Die zweite Steuereinheit meldet die Stellgröße an die erste Steuereinheit zurück. Die erste Steuereinheit vergleicht die Stellgröße und die Kraftstoffmengengröße miteinander auf Fehler.

Figure 00000001
Device and method for controlling an internal combustion engine, in particular a diesel internal combustion engine, with at least one quantity-determining actuator. A first control unit specifies a fuel quantity quantity QK depending on the first quantities. A second control unit determines a manipulated variable for the actuator based on the fuel quantity and other quantities. The second control unit reports the manipulated variable back to the first control unit. The first control unit compares the manipulated variable and the fuel quantity with each other for errors.
