Internal combustion engine operating method for motor vehicle, involves obtaining reference controlled variable by target value corrector, where corrector is dependant on correcting variable that is received at output of integral unit

Verfahren zum Betreiben einer Brennkraftmaschine

Abstract

The method involves regulating an actual controlled variable depending on a reference controlled variable. The reference controlled variable is obtained by a target value corrector (18). The corrector is dependant on a correcting variable which is received at the output of an integral unit (22). The corrector is temporarily dependant on the disturbance variable. The corrector depends on the difference between the correcting variable and the disturbance variable. Independent claims are also included for the following: (1) a computer program for operating an internal combustion engine (2) an electrical memory medium for a control or regulating mechanism of an internal combustion engine (3) a control and regulating mechanism for an internal combustion engine.
Bei einer Brennkraftmaschine (28), insbesondere eines Kraftfahrzeugs, wird eine Ist-Regelgröße (n ist ) abhängig von einer Soll-Regelgröße (n soll ) geregelt. Letztere wird durch eine Korrektur (18) einer Zielgröße (n ziel ) erhalten. Die Korrektur (18) hängt von einer Stellgröße (M I ) ab, die aus dem Ausgang eines Integralglieds (22) erhalten wird. Es wird vorgeschlagen, dass die Korrektur (18) wenigstens zeitweise auch von einer Störgröße (M L ) abhängt.
