Abstract
Die aktuelle Glühkerzentemperatur wird mit Hilfe eines mathematischen Verfahrens berechnet. Ausgehend von der letzten berechneten Glühkerzentemperatur wird dieser ein Faktor addiert. Dieser Faktor setzt sich aus einer Zeitdifferenz und einer Temperatursteigung zusammen, wobei diese beiden Werte miteinander multipliziert werden. Die Temperatursteigung wird dabei basierend auf einem hinterlegten Kennfeld bestimmt.The current glow plug temperature is calculated using a mathematical procedure. Starting from the last calculated glow plug temperature, this one factor is added. This factor is composed of a time difference and a temperature gradient, these two values being multiplied together. The temperature gradient is determined based on a stored map.
Description
Die Erfindung betrifft ein Verfahren zur Bestimmung einer Glühkerzentemperatur gemäß den Merkmalen des Oberbegriffs des Hauptanspruchs 1.The The invention relates to a method for determining a glow plug temperature according to the characteristics of the preamble of main claim 1.
Bei Dieselmotoren werden üblicherweise Glühkerzen eingesetzt, um ein Kaltstarten des Motors zu ermöglichen, da die Startwilligkeit von Dieselmotoren bei niedrigeren Temperaturen sinkt. Zur Steuerung von Glühkerzen in Brennkraftmaschinen ist es wichtig, den thermischen Zustand der Glühkerzen, insbesondere die Glühkerzentemperatur, zu kennen. Eine Abschätzung der Glühkerzentemperatur ist insofern notwendig, um eine Übersteuerung und Überhitzung der Glühkerze bei deren Versorgung mit einer maximal möglichen Batteriespannung zu vermeiden. Ein Risiko einer solchen Übersteuerung und/oder Überhitzung der Glühkerze und den damit verbundenen Folgeschäden für den Motor besteht insbesondere bei Glühphasen, bei denen die Glühkerze mit der maximal möglichen Batteriespannung beaufschlagt wird.at Diesel engines usually become glow plugs used to allow a cold start of the engine, as the start willingness of diesel engines at lower temperatures decreases. For controlling of glow plugs in internal combustion engines, it is important to know the thermal state of glow plugs, in particular the glow plug temperature, to know. An estimate the glow plug temperature is necessary in this respect to overdrive and overheat the glow plug when supplied with a maximum possible battery voltage avoid. A risk of such overdrive and / or overheating the glow plug and the associated consequential damage to the engine in particular during incandescent phases, where the glow plug with the maximum possible Battery voltage is applied.
