Abstract
(DE)
Es wird ein Verfahren zur adaptiven Klopfregelung und eine entsprechende Vorrichtung für eine benzindirekteinspritzende Brennkraftmaschine vorgeschlagen, wobei die Brennkraftmaschine in mindestens zwei Betriebszuständen betrieben wird. Für eine Klopfregelung werden relevante Spätverstellwinkel des Zündwinkels mittels eines anpassbaren Adaptionsvorgangs geregelt. Für die zwei Betriebszustände ist jeweils ein separates Adaptionskennfeld oder jeweils eine separate anpassbare Rechenvorschrift vorgesehen, wobei bei einem Wechsel des Betriebszustands der aktuelle Spätverstellwinkel aus dem Adaptionskennfeld des neuen Betriebszustands gelesen wird oder mittels der neuen anpassbaren Rechenvorschrift berechnet wird.
(EN)
The invention relates to a method for adaptively controlling knocking and to a corresponding device for a gasoline direct fuel injection internal combustion engine, whereby the internal combustion engine is operated in at least two operational states. For controlling knocking, relevant late advance angles of the ignition angle are controlled by means of an adaptable adaptation process. A separate adaptation mapping or a separate adaptable computation rule is provided each time for both operational states, whereby, during a change of the operational state, the actual late advance angle is read out of the adaptation mapping of the new operational state or is calculated using the new adaptable calculation rule.
(FR)
L'invention concerne un procédé de régulation adaptative du cliquetis et un dispositif correspondant pour un moteur à combustion interne à injection directe de l'essence. Ledit moteur à combustion interne est actionné dans au moins deux modes de fonctionnement. Pour assurer la régulation du cliquetis, des angles d'avance tardifs significatifs sont régulés par un processus d'adaptation adaptable. Pour les deux modes de fonctionnement, il est prévu dans chaque cas un champ caractéristique d'adaptation séparé ou une règle de calcul adaptable séparée. Lors d'un changement de mode de fonctionnement, l'angle d'avance tardif présent est extrait du champ caractéristique d'adaptation du nouveau mode de fonctionnement ou est calculé à l'aide de la nouvelle règle de calcul adaptable.
