Abstract
Description
Die vorliegende Erfindung betrifft ein Verfahren zum Start einer Brennkraftmaschine, wobei die Brennkraftmaschine eine Start-Stopp-Funktion aufweist, welche beispielsweise bei einem längeren Halt dafür sorgt, dass der Fahrzeugmotor abgeschaltet wird. Sobald der Fahrer die Fahrt wieder aufnehmen will, wird der Fahrzeugmotor neu gestartet.The The present invention relates to a method for starting an internal combustion engine, wherein the internal combustion engine has a start-stop function, which for example with a longer stop for it ensures that the vehicle engine is switched off. Once the driver wants to resume the journey, the vehicle engine is restarted.

Ausgehend von dem bekannten Stand der Technik besteht die Aufgabe der vorliegenden Erfindung darin, den Vorgang des automatischen Starten und Stoppens einer Brennkraftmaschine zu verbessern.outgoing from the known prior art, the object of the present Invention therein, the process of automatic starting and stopping an internal combustion engine to improve.
Diese Aufgabe wird mit den Merkmalen des unabhängigen Anspruchs gelöst. Das erfindungsgemäße Verfahren hat gegenüber dem Stand der Technik den Vorteil, dass nach dem Einleiten eines Stoppvorganges aufgrund verschiedener vorliegender Betriebsbedingungen bei einer Änderung einer dieser Betriebsbedingungen und ein sich daraus ergebenden gewünschter Wieder-Startvorganges dieser Startvorgang so ausgeführt wird, dass für den Fahrer keine Komforteinbuße entsteht. Hierzu wird die Motordrehzahl vorteilhaft in verschiedene Bereiche unterteilt, so dass je nachdem welche aktuelle Motordrehzahl beim Erkennen der Bedingungen für Wieder-Start vorliegen, verschiedene Abläufe für den Wieder-Start erfolgen. Bei einer sehr kurzen Zeit für das Erkennen der Bedingungen für Wieder-Start nach der vorherigen Einleitung eines Motorstopps kann auf das Bestromen des Starters vollständig verzichtet werden, da die kinetische Energie des Motors zu diesem Zeitpunkt für einen Wieder-Start ausreichend ist.These The object is achieved by the features of the independent claim solved. The inventive method has the advantage over the prior art that after initiating a stop due to various present ones Operating conditions when changing one of these operating conditions and a consequent desired reboot this boot process is executed so that for the driver no loss of comfort arises. For this purpose, the Engine speed advantageously divided into different areas, so that depending on which current engine speed when detecting the Conditions for re-start are present, different processes for the restart. In a very short time for recognizing the conditions for re-start after the previous initiation of a motor stop may be due to the energizing of the starter are completely dispensed with, since the kinetic Energy of the engine at this time for a re-start is sufficient.
Ausführungsbeispiele der Erfindung sind in den Figuren dargestellt und in der nachfolgenden Beschreibung näher erläutert.embodiments The invention is illustrated in the figures and in the following Description explained in more detail.

der Start-Stopp-Steuerung
Diese verschiedenen Bedingungen werden erfasst, auf das Vorliegen definierter und festgelegter Vorgaben hin überprüft und in Abhängigkeit der Auswertung dieser verschiedenen Bedingungen, die Start-Stopp-Funktion aktiviert.These different conditions are detected, which are defined and specified specifications Dependence of the evaluation of these different conditions, the start-stop function is activated.
Mit der erfindungsgemäßen Ansteuerung wird sichergestellt, dass nach dem Erkennen aller Bedingungen für einen Motorstopp und der entsprechenden steuergeräteseitigen Einleitung des Motorstopps der Motor schneller wieder gestartet werden kann, wenn sich die Bedingungen für den Motorstopp geändert haben, also eine Änderung der Motorstoppbedingungen erfolgt ist, z. B. weil sich die Absicht des Fahrers geändert hat.With the control according to the invention it is ensured that after detecting all conditions for engine stop and the corre sponding chenden ECU-side initiation of engine stop the engine can be restarted faster when the conditions for engine stop have changed, so a change in the engine stop conditions has occurred, eg. B. because the intention of the driver has changed.
Man nennt diese bedingte Änderungen change of mind. Mit der vorliegenden Lösung wird sichergestellt, dass der Motor im Falle von „change of mind” schneller wieder gestartet werden kann.you calls these conditional changes change of mind This solution ensures that the engine in the case of "change of mind" faster again can be started.
Hierzu wird der Starter jeweils direkt bei Einleitung eines Motorstopps in seinem Drehzahlbereich so angesteuert, dass er bei Gleichdrehzahl eingespurt werden kann. Im Normalfall läuft der Starter dann zusammen mit dem Motor bis zum Stillstand herunter. Wird während der Herunterlaufphase change of mind erkannt, so kann der Starter sofort wieder bestromt werden und der Motor kann schneller gestartet werden.For this The starter is each directly at the initiation of a motor stop in his speed range so controlled that he at constant speed can be harnessed. Normally the starter will run down to a standstill with the engine. Will while the run down phase change of mind detected, so the starter be re-energized immediately and the engine can start faster become.

Zum
Zeitpunkt t0 befindet sich der Motor im normalen Fahrbetrieb und
der Motor hat eine Drehzahl n0. In der Figur erfolgt zum Zeitpunkt
t1 eine Anforderung für einen Motorstopp, weil die definierten Vorraussetzungen
für einen Motorstopp vom Steuergerät
Mit
der Stoppanforderung t1 sinkt die Drehzahl des Motors, wie in der
Wird nun nach Einleiten des Motorstopps während des Herunterlaufs des Motors die Notwendigkeit eines Weiterlaufs bzw. des sofortigen Neustarts erkannt, werden je nachdem welche aktuelle Motordrehzahl beim Erkennen der Notwendigkeit des Weiterlaufs vorliegt, verschiedene Reaktionsbereiche unterschieden, die wie bereits weiter oben ausgeführt in der erfindungsgemäßen Anordnung drei Bereiche I, II, und III darstellen.Becomes now after initiating the engine stop during the descent of the engine the need for a continuation or the immediate Reboots detected, depending on what current engine speed in recognizing the need to continue, there are different ones Reaction areas distinguished, as stated above in the inventive arrangement, three areas I, II, and III represent.
Liegt dieser Zeitpunkt im Bereich I, wird die kinetische Restenergie des Motors genutzt und der Motor läuft weiter. In der Figur ist dieses Ereignis zum Zeitpunkt t2 dargestellt und der Drehzahlverlauf des Motors mit einem Change of Mind zum Zeitpunkt t2 mit der Linie A gezeigt. Wird die erneute Startanforderung erst zu einem Zeitpunkt t3 gegeben und die Drehzahl nM ist fast bist auf die Grenze des Bereiches I abgefallen, dann reicht die kinetische Energie des Motors gerade noch aus, um den Motor alleine oder wieder hochlaufen zu lassen. Hier mit der punktierten Linie B dargestellt.Lies this time in area I, the kinetic residual energy of the Motors used and the engine keeps running. In the figure this event is shown at time t2 and the speed history of the engine with a change of mind at time t2 with the line A shown. Will the restart request be at a time given t3 and the RPM nM is almost on the limit of the limit Range I dropped, then the kinetic energy of the engine is enough just about to crank up the engine alone or again to let. Shown here with the dotted line B.
Nur eine minimale Zeit nach t3 zum Zeitpunkt t4 ist jedoch die Grenze des Bereichs I bereits überschritten und es muss zum Motorstart der Starter bestromt werden. Damit dreht der Starter hoch und spurt in den herunterdrehenden Motor ein. In der Figur ist die Drehzahl des Starters mit nSt dargestellt und es ist deutlich zu erkennen, dass der Starter mit dem Change of Mind zum Zeitpunkt t4 sich anfängt zu drehen. Zum Zeitpunkt t5 hat der Starter die gleiche Drehzahl wie der herunterlaufende Motor erreicht. Das bedeutet beide Drehzahlen sind gleich, nM entspricht nSt. Damit sind diese drehenden Elemente synchron und der Starter kann eingespurt werden, um die Motordrehzahl, wie mit Kurve C gezeigt, wieder auf Betriebsniveau anzuheben.Just however, a minimum time after t3 at time t4 is the limit of area I already exceeded and it has to start the engine the starter will be energized. The starter will turn up and spurt in the turning down engine. In the figure, the speed of the starter with nSt and it can be clearly seen that the starter with the change of mind starts at time t4 too rotate. At time t5, the starter has the same speed as the engine is running down. That means both speeds are the same, nM equals nSt. So these are rotating elements synchronous and the starter can be meshed to the engine speed, as shown by curve C, to raise back to operating level.
Mit der Kurve D ist gezeigt, wie der Motorsteuerung reagiert, wenn Change of Mind zum Zeitpunkt t6 erfolgt und die Motordrehzahl bereits im Bereich III liegt. Hier ist ein Abfangen des Motors nicht mehr möglich und es wird der Motorauslauf abgewartet. Die Motordrehzahl nM fällt auf einen Wert für den Motorstillstand ab. Nun wird der Starter eingespurt und dann bestromt, so dass wie bei einem herkömmlichen Anfahrvorgang üblich der Starter im eingespurten Zustand gemeinsam mit dem Motor hochdreht.With The curve D shows how the engine control responds when change of Mind is done at time t6 and the engine speed is already in Area III lies. Here a catching of the engine is no longer possible and wait for the engine to stop. The engine speed nM falls to a value for the engine standstill. Now the Starter meshed and then energized, so that as a conventional Starting procedure usual the starter in einpurten state up with the engine.
Die Unterscheidung der verschiedenen Steuerungen aufgrund der aktuellen Motordrehzahl nach Motorstopp zum Zeitpunkt der Erkennung eines erneuten Motorstarts bewirkt, dass die Schwungenergie zur Gewinnung elektrischer Energie genutzt werden kann. Hierzu wird der Starter nach dem Einspuren als Generater betrieben und damit die Phase des Herunterlaufs des Motors vorteilhaft verkürzt.The Differentiation of different controls due to the current Engine speed after engine stop at the time of detection of a new Motor starts causes the flywheel energy to generate electrical Energy can be used. For this purpose, the starter after the Einspuren operated as a generator and thus the phase of the descent of the Motors shortened advantageous.
Damit wird ein Teil der für den Motorstart benötigen Energie aus der Schwungenergie de Motors generiert.In order to will need part of the engine start Energy generated from the flywheel energy of the engine.
