Exhaust gas system`s temperature determining method for internal-combustion engine of motor vehicle, involves separately computing contributions arrived in energy balancing during modeling of temperature in exhaust gas system

The method involves calculating temperature and/or temperature sequence of an exhaust gas in an exhaust gas system of an internal-combustion engine (1) from energy balancing based on an operating parameter. Contributions arrived in the energy balancing are computed separately during the modeling of...

Beschreibung
Zusammenfassung:	The method involves calculating temperature and/or temperature sequence of an exhaust gas in an exhaust gas system of an internal-combustion engine (1) from energy balancing based on an operating parameter. Contributions arrived in the energy balancing are computed separately during the modeling of the temperature. Calculated and/or existing operating intermediate parameters are included in a control equipment (100), during the modeling of the temperature. A modular computation of the partial contributions is accomplished for energy balancing, during the modeling of the temperature. Die Erfindung betrifft ein Verfahren zur Temperaturbestimmung im Abgassystem einer Brennkraftmaschine mit einer Steuereinrichtung, wobei ausgehend von mindestens einer Betriebsgröße eine Temperatur bzw. ein Temperaturverlauf eines Abgases im Abgassystem aus einer Energiebilanzierung berechnet wird. Um den Applikationsaufwand bei der Temperaturbestimmung im Abgassystem zu reduzieren und dabei Ressourcen zu schonen, werden bei einer Modellierung der Temperatur die in die Energiebilanzierung eingehenden Beiträge getrennt berechnet.
