Description

Die Erfindung betrifft ein Verfahren zur Erkennung einer Aktivierung bei einer Startvorrichtung einer Brennkraftmaschine zur Initialisierung eines Glühvorgangs einer Glühkerze gemäß den Merkmalen des Oberbegriffs des Hauptanspruchs 1.The The invention relates to a method for detecting an activation at a starting device of an internal combustion engine for initialization an annealing process a glow plug 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. Eine weitere Aufgabe der Glühkerzen ist es, den Verbrennungsprozess derart zu unterstützen, dass ein verbessertes Abgasverhalten der Brennkraftmaschine erzielt wird. Insbesondere soll mit den Glühkerzen eine Erhöhung der Last verursacht werden, die zu einer Anhebung der Abgastemperatur führt, und somit eine Abgasnachbehandlung, in z.B. einem Russfilter, erfolgen kann. Um den Verbrennungsprozess optimal zu unterstützen ist jedoch der Zeitpunkt der Aktivierung einer Startvorrichtung (z.B. Schlüssel umdrehen) möglichst exakt zu bestimmen. Nur dadurch kann ein zeitlich der Startphase optimal zugeordneter Glühvorgang der Glühkerzen sichergestellt werden.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. Another Task of the glow plugs is to support the combustion process such that an improved exhaust gas performance of the internal combustion engine is achieved. In particular, should with the glow plugs a increase causing the load to increase the exhaust gas temperature leads, and thus an exhaust aftertreatment, in e.g. a soot filter, done can. To optimally support the combustion process however, the timing of activation of a starting device (e.g. key turn around) as possible to determine exactly. Only this can be a time of the startup phase optimally assigned annealing process the glow plugs be ensured.

Aus dem Stand der Technik sind Verfahren bekannt, bei denen die Bestimmung der Aktivierung der Startvorrichtung dadurch erfolgt, dass von der Startvorrichtung ein Signal ausgesandt wird und/oder die Entwicklung der Motordrehzahl betrachtet und ausgewertet wird.Out The prior art discloses methods in which the determination the activation of the starting device takes place in that of the starting device a signal is emitted and / or the evolution of the engine speed considered and evaluated.

Die der vorliegenden Erfindung zu Grunde liegende Aufgabe besteht nun darin, ein Verfahren bereitzustellen, das unabhängig vom Startersignal und der Betrachtung der Motordrehzahl eine Aktivierung der Startvorrichtung identifiziert.The The object underlying the present invention is now to provide a method that is independent of the starter signal and considering the engine speed activation of the starting device identified.

Diese Aufgabe wird erfindungsgemäß durch die Merkmale des Patentanspruchs 1 gelöst. Vorteilhafte Ausgestaltungen der Erfindung sind in den Unteransprüchen gekennzeichnet.These The object is achieved by the Characteristics of claim 1 solved. Advantageous embodiments The invention are characterized in the subclaims.

Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, dass eine Aktivierung der Startvorrichtung durch eine Beobachtung der Batteriespannung erfolgt. Die Batteriespannung ist eine Größe, die unabhängig von der Startvorrichtung oder den Betriebszuständen der Kraftmaschine kontinuierlich ermittelt wird. Die Batteriespannung steht somit zusätzlich zu den anderen bekannten Größen für die Einleitung des Glühvorgangs jederzeit zur Verfügung.The particular advantages of the invention are that activation of the starting device by an observation the battery voltage occurs. The battery voltage is a size that independently from the starting device or the operating conditions of the engine continuously is determined. The battery voltage is thus in addition to the other known sizes for the introduction of the annealing process available at any time.

Einzelheiten der Erfindung werden anhand der Zeichnung näher erläutert. Dabei zeigt:details The invention will be explained in more detail with reference to the drawing. Showing:

1: den Spannungsverlauf und den Verlauf des Aktivierungssignals der Startvorrichtung. 1 : the voltage curve and the course of the activation signal of the starting device.

1 zeigt den zeitlichen Verlauf der Batteriespannung und des Aktivierungssignals der Startvorrichtung. Dabei entspricht die Kennlinie 1 dem Spannungsverlauf der Batterie und die Kennlinie 2 dem Aktivierungssignal der Startvorrichtung. Die Kennlinie U entspricht dem unteren Grenzwert des Spannungsverlaufs, ab dem auf eine Aktivierung der Startvorrichtung geschlossen wird. 1 shows the time course of the battery voltage and the activation signal of the starting device. The characteristic corresponds to this 1 the voltage curve of the battery and the characteristic curve 2 the activation signal of the starting device. The characteristic U corresponds to the lower limit of the voltage curve, from which an activation of the starting device is concluded.

Zum Zeitpunkt t1 erfolgt eine Aktivierung der Startvorrichtung, was an einem Anstieg der Kennlinie 2 sichtbar wird. Ein Spannungsabfall an der Kennlinie 1 kann dabei zu einem früheren Zeitpunkt t0, z.B. aufgrund der Zuschaltung von externen Lasten an die Batterie, die von dem Zeitpunkt der Aktivierung unabhängig sind, erfolgen. Die Zuschaltung der externen Lasten erfolgt dabei nur unter definierten Bedingungen, z.B. dann, wenn vom Schlüssel aus ein Befehl an eine Empfangseinheit gesendet wird. Die Startphase endet im Zeitpunkt t2, was zu einer Erhöhung des Spannungsverlaufs der Kennlinie 1 und einem Abfall des Aktivierungssignals der Kennlinie 2 führt.At the time t1, the starting device is activated, which is due to an increase in the characteristic curve 2 becomes visible. A voltage drop across the characteristic 1 can be done at an earlier time t0, for example due to the connection of external loads to the battery, which are independent of the time of activation. The external loads are connected only under defined conditions, eg when a command is sent from the key to a receiving unit. The starting phase ends at time t2, which leads to an increase in the voltage curve of the characteristic curve 1 and a fall of the activation signal of the characteristic 2 leads.

Auf eine Aktivierung der Startvorrichtung wird geschlossen, wenn der Spannungsabfall der Kennlinie 1 kleiner/gleich dem unteren Grenzwert der Kennlinie U ist und/oder sich der Spannungswert für eine vorgebbare Zeitdauer unterhalb des unteren Grenzwerts U befindet. Die Zeitdauer darf dabei aber nicht länger als die Zeitdifferenz zwischen t2 und t0 betragen.On activation of the starting device is closed when the voltage drop of the characteristic 1 is less than / equal to the lower limit of the characteristic curve U and / or the voltage value is below the lower limit value U for a predefinable time duration. The time period may not be longer than the time difference between t2 and t0.
