Title
(DE) VERFAHREN UND STEUERGERÄT ZUR EINSTELLUNG EINER TEMPERATUR EINER GLÜHSTIFTKERZE
(EN) METHOD AND CONTROL DEVICE FOR ADJUSTING A TEMPERATURE OF A GLOW PLUG
(FR) PROCÉDÉ ET APPAREIL DE COMMANDE POUR RÉGLER UNE TEMPÉRATURE D'UNE BOUGIE-CRAYON DE PRÉCHAUFFAGE
Abstract
(DE) Die Erfindung betrifft ein Verfahren zur Einstellung einer Temperatur einer Glühstiftkerze, insbesondere zur Zündung eines Kraftstoff-Luft-Gemisches in einem Verbrennungsmotor, bei welchem die Temperatur (Tm) der Glühstiftkerze (2) in Abhängigkeit eines Widerstandes (Rm) der Glühstiftkerze (2) mittels einer Regelung eingestellt wird. Um das Auftreten von Temperaturüberschwingern während der Vorheizphase der Glühstiftkerze zu unterbinden, wird die Temperatur (Tm) in einer Vorheizphase, in welcher eine Überspannung an die Glühstiftkerze (2) angelegt wird, mit Hilfe eines prädiktiven Modells (8) geregelt.
(EN) The invention relates to a method for adjusting a temperature of a glow plug, in particular for igniting a fuel/air mixture in an internal combustion engine, wherein the temperature (Tm) of the glow plug (2) is adjusted by means of a regulating system dependent on a resistance (Rm) of the glow plug (2). The aim of the invention is to prevent the occurrence of temperature overhoots during the pre-heating phase of the glow plug. This is achieved in that the temperature (Tm) is regulated using a predictive model (8) in a pre-heating phase in which an overvoltage is applied to the glow plug (2).
(FR) L'invention concerne un procédé pour régler une température d'une bougie-crayon de préchauffage, en particulier pour allumer un mélange carburant-air dans un moteur à combustion interne, selon lequel la température (Tm) de la bougie-crayon de préchauffage (2) est réglée au moyen d'un réglage en fonction d'une résistance (Rm) de la bougie-crayon de préchauffage (2). Pour empêcher que des fluctuations de température surviennent pendant la phase de préchauffage de la bougie-crayon de préchauffage, la température (Tm) est réglée à l'aide d'un modèle prédictif (8) dans une phase de préchauffage dans laquelle une surtension est appliquée à la bougie-crayon de préchauffage (2).
