Description
Die vorliegende Erfindung betrifft ein Verfahren zur Begrenzung des Hochdrehens eines mit einer elektronischen Motorsteuerung versehenen Antriebsmotors für ein Kraftfahr zeug gemäß dem Oberbegriff des Patentanspruchs 1.The present invention relates to a method for Limiting the cranking one with an electronic one Motor control provided drive motor for a motor vehicle according to the preamble of claim 1.
Es wurde festgestellt, dass ein vor der Auslieferung eines fabrikneuen Fahrzeuges an den Endkunden erfolgender Mißbrauch des Fahrzeuges eine schädliche Auswirkung auf das spätere Lauf- und Verbrauchsverhalten des Motors bewirken kann.It was found that one before delivery of a brand new vehicle to the end customer Misuse of the vehicle has a detrimental effect on that cause later running and consumption behavior of the engine can.
Beispielsweise bei der Verladung des Fahrzeugs auf Schiffe, auf die Bahn oder auch auf Lastkraftwagen kommt es immer wieder vor, dass die neuen Motore dieser Fahrzeuge im noch kalten Zustand bis an die Drehzahlgrenze belastet wer den und dadurch Schaden nehmen, welcher sich z. B. in einem erhöhten Kraftstoffverbrauch über die gesamte Fahrzeugle bensdauer auswirkt.For example, when loading the vehicle Ships, on the train or even on trucks again and again that the new engines of these vehicles in the who is still cold up to the speed limit the and thereby take damage, which z. B. in one increased fuel consumption across the entire vehicle affects life.
Hierbei handelt es sich um einen vom Endkunden nicht sofort zu erkennenden versteckten Mangel, wobei es im Nach hinein schwierig ist, den Verursacher zu ermitteln und zu belangen.This is not one of the end customer immediately recognizable hidden defect, being there in the after it is difficult to identify the cause and to sue.
Die DE 28 00 433 A1 lehrt ein Verfahren, bei dem die zulässige Maximaldrehzahl während der Einfahrzeit begrenzt ist. Dabei besteht die Einfahrzeit aus zwei Phasen, während derer unterschiedliche Maximaldrehzahlen vorgegeben sind. DE 28 00 433 A1 teaches a method in which the permissible maximum speed is limited during the break-in period is. The break-in period consists of two phases, during whose different maximum speeds are specified.
In der US 4,615,316 A ist ebenso ein Verfahren zur Begrenzung des Hochdrehens eines Antriebsmotors beschrie ben, bei dem die zulässige Belastung während der Einfahr zeit graduell bis zu dem Endwert des Normalbetriebs erhöht wird.In US 4,615,316 A is also a method for Limitation of the revving of a drive motor described ben, at which the permissible load during the retraction time gradually increased to the end value of normal operation becomes.
Bei diesen bekannten Verfahren erfolgt die Begrenzuung während der gesamten Einfahrzeit durch einen vom Fahrer nicht beeinflussbaren Eingriff in die Motorsteuerung. Auch in kritischen Verkehrssituationen, z. B. beim Überholen, steht also nicht die volle Motorleistung zur Verfügung.Limitation takes place in these known methods by the driver during the entire break-in period intervention in the engine control that cannot be influenced. Also in critical traffic situations, e.g. B. when overtaking, So the full engine power is not available.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Verfahren aufzuzeigen, das zuverlässig einen Missbrauch während der Überführung des Fahrzeugs verhindert und wäh rend der Einfahrphase dazu dient, ungewollte, unzulässige Belastungen zu vermeiden, wobei keine Einschränkungen der aktiven Fahrsicherheit während der Einfahrzeit verursacht werden sollen.The invention is therefore based on the object To demonstrate procedures that reliably abuse prevented and during the transfer of the vehicle during the running-in phase serves to prevent unwanted, inadmissible To avoid stress, with no restrictions on the active driving safety during the break-in period should be.
Die Lösung dieser Aufgabe erfolgt durch ein Verfahren mit den Merkmalen des Anspruchs 1.This problem is solved by a method with the features of claim 1.
Vorteilhafte Ausgestaltungen sind in den Unteransprü chen beschrieben.Advantageous configurations are in the subclaims Chen described.
Erfindungsgemäß wird also vorgeschlagen, dass, nachdem eine bestimmte Mindest-Fahrstrecke zurückgelegt wurde, bei einer Überschreitung der zulässigen Belastung während der Einfahrzeit nur noch ein Hinweis an den Fahrer gegeben wird, so dass in kritischen Situationen die volle Motor leistung zur Verfügung steht. According to the invention, it is therefore proposed that, after a certain minimum distance traveled was at exceeding the permissible load during the Break-in time just a note to the driver will, so in critical situations the full engine performance is available.
Der Hinweis an den Fahrer kann durch eine Warnlampe oder ein akustisches Signal gegeben werden.The warning to the driver can be given by a warning lamp or an acoustic signal can be given.
Die maximal zulässige Belastung des Motors kann z. B. durch einen Drosselklappenwert Dki, eine maximale Motor drehzahl n_max oder ein maximales Motordrehmoment M_mot_max = a × M_nenn (= Nenndrehmoment) definiert werden. Bevorzug te Werte für Dki, n_max oder a sind für einen Otto-Motor z. B. Dki = 50%, n_max = 4000 1/min, a = 50%.The maximum permissible load on the engine can e.g. B. by a throttle value Dki, a maximum engine speed n_max or a maximum motor torque M_mot_max = a × M_nom (= nominal torque) can be defined. Favor te values for Dki, n_max or a are for an Otto engine z. B. Dki = 50%, n_max = 4000 1 / min, a = 50%.
Die zurückgelegte Fahrstrecke, d. h. der km-Stand kann dabei zwischen einem niedrigen Wert, z. B. 10 km und einem die volle Einfahrstrecke eines fabrikneuen Fahrzeugs von beispielsweise 1500 km eingestellt werden. Während dieser gesamten Einfahrstrecke von beispielsweise 1500 km, kann also die zulässige Motorbelastung n, M, Dki etc., abhängig von der Kilometerleistung auch Zug um Zug angehoben werden.The distance traveled, i.e. H. the mileage can thereby between a low value, e.g. B. 10 km and one the full drive-in distance of a brand new vehicle from For example, 1500 km can be set. During this total drive-in distance of 1500 km, for example thus the permissible engine load n, M, Dki etc., dependent mileage can also be increased step by step.
Die im Patentanspruch 1 angesprochene Abregelung des Motors kann beispielsweise durch eine Verringerung der Ein spritzdauer, der Einspritzmenge oder durch eine Veränderung des Zündzeitpunktes erfolgen.The reduction of the addressed in claim 1 Motors can, for example, by reducing the on injection duration, the injection quantity or by a change of the ignition point.
