Abstract

The method involves implementing a function in the engine controller that limits the engine loading to a defined value if the distance travelled by the vehicle is less than a defined value. The maximum permissible load is increased step by step with distance until the end of a running in distance

Description

Die vorliegende Erfindung betrifft ein Verfahren zur Begrenzung des Hochdrehens eines mit einer elektronischen Motorsteuerung versehenen Antriebsmotors für ein Kraftfahr­ zeug.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 stuff.

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 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 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 matter.

Aufgabe der vorliegenden Erfindung ist es, ein Verfah­ ren zur Begrenzung des Hochdrehens eines Antriebsmotors als Funktion der zurückgelegten Fahrstrecke des Fahrzeugs zu schaffen, um einen derartigen Mißbrauch auszuschließen. The object of the present invention is a method ren to limit the revving of a drive motor as Function of the distance traveled by the vehicle create to rule out such abuse.  

Ausgehend von einem Verfahren der eingangs näher ge­ nannten Art erfolgt die Lösung dieser Aufgabe mit dem im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmal; vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.Based on a method of ge closer named kind the solution of this task with the in characterizing part of claim 1 specified feature; advantageous embodiments are in the subclaims described.

Erfindungsgemäß wird also vorgeschlagen, daß in der elektronischen Motorsteuerung eine Funktion, abhängig von der vom Fahrzeug zurückgelegten Fahrstrecke, abgelegt ist, die bei Erfüllung der Bedingung
According to the invention, it is therefore proposed that a function is stored in the electronic engine control, depending on the distance traveled by the vehicle, when the condition is met

wenn km-Stand < x, dann B_max = y
if mileage <x, then B_max = y

den Motor abregelt, wobei B_max die maximal zulässige Bela­ stung des Motors darstellt.regulates the engine, where B_max is the maximum permissible load engine performance.

Die Abregelung des Motors kann dabei beispielsweise durch eine Verringerung der Einspritzdauer, der Einspritz­ menge oder durch eine Veränderung des Zündzeitpunktes er­ folgen.The limitation of the engine can, for example by reducing the injection duration, the injection quantity or by changing the ignition timing consequences.

Die maximal zulässige Belastung B_max des Motors kann z. B. durch einen Drosselklappenwert Dki, eine maximale Motordrehzahl n_max oder ein maximales Motordrehmo­ ment M_mot_max = a × M_nenn (= Nenndrehmoment) definiert werden. Bevorzugte 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 B_max of the motor can e.g. B. by a throttle valve value Dki, a maximum Engine speed n_max or a maximum engine torque ment M_mot_max = a × M_nenn (= nominal torque) defined become. Preferred 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 x 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., ab­ hängig von der Kilometerleistung auch Zug um Zug angehoben werden.The distance traveled, i.e. H. the mileage x can be between a low value, e.g. B. 10 km and the full drive-in distance of a brand new vehicle of 1500 km, for example. While  this entire entry distance of 1500 km, for example, can therefore the permissible engine load n, M, Dki etc., from depending on the mileage also raised step by step become.

Die abgelegte Funktion verhindert zuverlässig einen Mißbrauch des fabrikneuen Motors durch unzulässiges Hoch­ drehen, d. h. unzulässig große Drehzahl, welche insbesonde­ re in kaltem Zustand schädlich ist.The stored function reliably prevents you Misuse of the brand-new engine due to an inadmissible high turn, d. H. impermissibly high speed, which in particular re harmful when cold.

Anstatt eines harten Eingriffs durch die elektronische Motorsteuerung kann ab einer bestimmten Mindest-Fahrstrecke während der Einfahrzeit auch ein Hinweis an den Fahrer in Form einer Warnlampe oder eines akustischen Signals vor­ teilhaft sein, so daß in kritischen Situationen die volle Motorleistung zur Verfügung steht.Instead of a hard intervention by the electronic Motor control can start from a certain minimum driving distance a note to the driver during the break-in period Form of a warning lamp or an acoustic signal be partaking, so that in critical situations the full Engine power is available.
