Description

Die vorliegende Erfindung betrifft ein System und ein Verfahren zum kontrollierten Abbrechen eines Startversuches für einen Verbrennungsmotor, insbesondere für einen Boxermotor eines Motorrads.The present invention relates to a system and method for controlled termination a start attempt for an internal combustion engine, in particular for a Boxer engine of a motorcycle.

Üblicherweise werden Verbrennungsmotoren mittels eines als Anlasser bezeichneten Elektromotors gestartet. Die Betätigung des Anlassers erfolgt bei Kraftfahrzeugen üblicherweise durch Drehen des Zündschlüssels im Zündschloß. Dabei wird ein Startschalter betätigt. Bei Motorrädern erfolgt die Betätigung des Anlassers dagegen üblicherweise durch einen separaten Startknopf bzw. -schalter, der nach Einschalten der Zündung mit dem Zündschlüssel betätigt werden muß. In beiden Fällen wird der Anlasser bei einem Startversuch nur solange betrieben, wie der Startschalter betätigt wird, d. h. bis zum Loslassen des Zündschlüssels beim Kraftfahrzeug bzw. des Startknopfes beim Motorrad.Combustion engines are usually referred to as a starter Electric motor started. The starter is usually actuated in motor vehicles by turning the ignition key in the ignition lock. This will be a start switch actuated. In the case of motorcycles, however, the starter is usually actuated by a separate start button or switch, which, after switching on the Ignition must be operated with the ignition key. In both cases, the starter during a start attempt, only operate as long as the start switch is actuated, d. H. until the ignition key is released from the motor vehicle or the start button on the motorcycle.

Von Zeit zu Zeit geschieht es, daß der Startschalter losgelassen wird, bevor der Verbrennungsmotor läuft. Ein derartiger verfrühter Abbruch des Startvorganges führt bei Verbrennungsmotoren, insbesondere bei Boxermotoren unter Umständen zum Rückdrehen des Motors, wodurch das im Verbrennungsraum bzw. in den Verbrennungsräumen befindliche Kraftstoff-Luft-Gemisch sich durch den Zündvorgang in den Saugrohren entzündet. Dies kann zu Beschädigungen des Motors, insbesondere der Saugrohre, und in Extremfällen sogar zu deren "Absprengen" führen. Ferner kann die Kraftstoffleitung durch einen derartigen Zündvorgang abreißen und Kraftstoff auslaufen bzw. herausspritzen (p ≤ 3,0 bar).From time to time it happens that the start switch is released before the internal combustion engine running. Such an early termination of the starting process leads to Internal combustion engines, in particular with boxer engines, can possibly be turned back of the engine, which in the combustion chamber or in the combustion chambers fuel-air mixture located in the intake manifolds due to the ignition process inflamed. This can damage the engine, especially the intake manifolds, and in extreme cases even lead to their "blasting". Furthermore, the fuel line tear off by such an ignition process and leak or spray fuel (p ≤ 3.0 bar).

Dieses Problem wird herkömmlicherweise durch mechanische Sicherungsmaßnahmen entschärft. Jedoch findet selbst dann die Zündung bzw. die Explosion des Kraftstoff-Luft-Gemisches nach wie vor im Ansaugschnorchel statt und kann zu Schäden am Fahrzeug bzw. am Motor führen. Ferner sind diese bekannten Sicherungsmaßnahmen technisch aufwendig, teuer und optisch störend.This problem is traditionally addressed by mechanical security measures defused. However, even then the ignition or explosion of the fuel-air mixture takes place still take place in the intake snorkel and can damage the Drive the vehicle or the engine. Furthermore, these are known security measures technically complex, expensive and visually disturbing.

Aus der DE-A-197 27 595 ist ein Verfahren und eine Vorrichtung zum Starten einer Brennkraftmaschine bekannt, die sich mit den Problemen der Startresonanz beschäftigt. DE-A-197 27 595 describes a method and a device for starting a Internal combustion engine known that deals with the problems of the start resonance.

Gemäß diesem Verfahren und dieser Vorrichtung wird der Brennkraftmaschine mit Beginn des Startvorganges Kraftstoff zugeführt, das Ende der Startbetätigung ermittelt oder erfaßt, die Drehzahl der Brennkraftmaschine mit einer in Abhängigkeit von einem Zustandsparameter der Brennkraftmaschine ermittelten Grenzdrehzahl verglichen und der Startvorgang fortgesetzt, falls die Drehzahl größer als die Grenzdrehzahl ist und ansonsten abgebrochen. Ein kontrolliertes Abbrechen des Startvorganges ist dieser Druckschrift jedoch nicht zu entnehmen.According to this method and device, the internal combustion engine is started fuel supplied during the starting process, the end of the starting operation is determined or detects the speed of the internal combustion engine with a function of one State parameters of the internal combustion engine determined limit speed and compared the start process continues if the speed is greater than the limit speed and otherwise canceled. This is a controlled abort of the starting process However, the document cannot be found.

Die EP-A-1 001 151 betrifft ein Verfahren und eine Vorrichtung zum kontrollierten Abstellen eines Verbrennungsmotors, der eine Kraftstoff-Einspritzsteuerung und eine Zündsteuerung umfaßt und bei der ein unmittelbar oder mittelbar mit dem Verbrennungsmotor gekoppelter Elektromotor und/oder Generator (Elektro-Maschine) sowie eine weitere Steuerung vorgesehen ist. Um ein kontrolliertes Abstellen zu gewährleisten, wird ein Abstellsignal für den Verbrennungsmotor erfaßt, die Kraftstoffeinspritzung bei gleichzeitiger Aufrechterhaltung der Zündung unterbrochen, eine bestimmte Motordrehzahl über eine bestimmte Zeit oder eine bestimmte Anzahl von Kurbelwellenumdrehungen mittels der Elektro-Maschine aufrechterhalten, und schließlich der Verbrennungsmotor mittels der Elektro-Maschine gestoppt.EP-A-1 001 151 relates to a method and a device for controlled parking of an internal combustion engine, the fuel injection control and Ignition control includes and one directly or indirectly with the internal combustion engine coupled electric motor and / or generator (electric machine) as well a further control is provided. To ensure controlled parking, a shutdown signal for the internal combustion engine is detected, the fuel injection interrupted while maintaining the ignition, a certain engine speed over a certain time or a certain number of crankshaft revolutions maintained by means of the electric machine, and finally the internal combustion engine stopped by means of the electric machine.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung bzw. ein System sowie ein Verfahren für einen kontrollierten Startabbruch beim Anlassen eines Verbrennungsmotors bereitzustellen. Diese Aufgabe wird mit den Merkmalen der Patentansprüche gelöst.The object of the present invention is an apparatus or a system as well as a procedure for a controlled abort when starting an engine To provide internal combustion engine. This object is achieved with the features of the claims solved.

Die Erfindung geht dabei von dem Grundgedanken aus, einen eingeleiteten Startabbruch zu einem unkritischen Zeitpunkt zu beenden. Dazu wird erfindungsgemäß beim Einleiten des Startabbruchs, d. h. beim Loslassen des Startschalters bzw. des Zündschlüssels, die Zufuhr des Kraftstoff-Luft-Gemisches unterbunden und die Zündung abgeschaltet, wobei gleichzeitig der Anlasser weiterhin eingespurt bzw. eingerückt bleibt, um ein Rückdrehen des Motors zu verhindern.The invention is based on the basic idea of initiating an aborted start to end at an uncritical point in time. For this purpose, according to the invention Initiate the abort, d. H. when you release the start switch or the ignition key, the supply of the fuel-air mixture is cut off and the ignition is switched off, at the same time the starter remains engaged or engaged, to prevent the engine from turning back.

Dadurch wird auf effektive und sichere Weise ein vollautomatischer Startabbruch gewährleistet, der Schäden am Motor und/oder Fahrzeug sowie mögliche Verletzungen verhindert und die bisher üblichen mechanischen Sicherungsmaßnahmen überflüssig macht.This ensures a fully automatic start abort in an effective and safe manner, the damage to the engine and / or vehicle and possible injuries prevented and the usual mechanical security measures superfluous makes.

Eine bevorzugte Ausführungsform der vorliegenden Erfindung wird nachstehend unter Bezugnahme auf die Zeichnung beispielhaft beschrieben. Es zeigt:

Fig. 1
eine schematische Darstellung einer Ausführungsform des erfindungsgemäßen Startabbruchsystems für einen Verbrennungsmotor.
A preferred embodiment of the present invention is described below by way of example with reference to the drawing. It shows:
Fig. 1
is a schematic representation of an embodiment of the start abort system according to the invention for an internal combustion engine.

Das in Fig. 1 schematisch dargestellte erfindungsgemäße System zeigt einen Anlasser 2 zum Anlassen eines Verbrennungsmotors 4 auf herkömmliche Weise. Dazu kann der Anlasser 2 mit dem Motor 4 mittels einer Einspur- bzw. Einrückeinrichtung 6 verbunden und nach erfolgtem Starten des Motors 4 voneinander getrennt werden. Zum Auslösen bzw. Einleiten des Startvorganges steht der Anlasser 2 mit einem Startschalter 8 in Verbindung, beispielsweise in Form eines Startknopfes beim Motorrad oder der bei Kraftfahrzeugen üblichen Ausgestaltung des Zündschlosses. Bei einem (durch den Pfeil 10 angedeuteten) Betätigen des Startschalters 8 wird der Anlasser 2 in Gang gesetzt. Um das vom Anlasser 2 abgegebene Drehmoment auf den Motor 4 zu übertragen, muß die Einrückeinrichtung 6 eingerückt werden, wozu eine Betätigungseinrichtung 12 vorgesehen, die mit einer mit dem Startschalter 8 in Verbindung stehenden Einrücksteuerung 14 in Verbindung steht. Das heißt, beim Betätigen des Startschalters 8 wird ein entsprechendes Steuersignal an die Einrücksteuerung 14 übermittelt, die wiederum ein Signal an die Betätigungseinrichtung 12 weiterleitet, um die Einrückeinrichtung 6 einzurücken. Gleichzeitig wird beim Betätigen des Startschalters 8 jeweils ein Signal an eine Einspritzsteuerung 16 sowie an eine Zündsteuerung 18 weitergegeben. Daraufhin setzt die Einspritzsteuerung 16 eine Einspritzanlage 20 und die Zündsteuerung 18 eine Zündanlage 22 in Funktionsbereitschaft, so daß beim Drehen des Motors 4 durch den Anlasser 2 Kraftstoff-Luft-Gemisch eingespritzt und zur Explosion gebracht wird.The system according to the invention shown schematically in FIG. 1 shows a starter 2 for starting an internal combustion engine 4 in a conventional manner. In addition, the Starter 2 connected to engine 4 by means of an engagement or engagement device 6 and after starting the engine 4 are separated from each other. To trigger or initiating the starting process, the starter 2 is in with a start switch 8 Connection, for example in the form of a start button on the motorcycle or at Motor vehicle design of the ignition lock. With one (by the arrow 10 indicated) actuation of the start switch 8, the starter 2 is started. In order to transmit the torque delivered by the starter 2 to the engine 4, the engagement device 6 are engaged, for which purpose an actuating device 12 is provided, with an engagement control connected to the start switch 8 14 communicates. That is, when the start switch 8 is operated, a Corresponding control signal transmitted to the engagement controller 14, which in turn Forwards the signal to the actuating device 12 in order to engage the engagement device 6. At the same time, when the start switch 8 is actuated, a signal is sent to each Injection control 16 and passed on to an ignition control 18. Thereupon sets the injection control 16 an injection system 20 and the ignition control 18 an ignition system 22 ready for operation so that when the engine 4 is rotated by the starter 2 fuel-air mixture is injected and detonated.

Wie in Fig. 1 schematisch dargestellt, können die Einrücksteuerung 14, die Einspritzsteuerung 16 und die Zündsteuerung 18 in einer gemeinsamen Steuerungseinrichtung 24 zusammengefaßt sein. Diese Steuerungseinrichtung 24 kann wiederum ein Bestandteil der gesamten Motorsteuerung sein. As shown schematically in Fig. 1, the engagement controller 14, the injection control 16 and the ignition control 18 in a common control device 24 be summarized. This control device 24 can in turn be a component of the entire engine control system.

Das vorstehend beschriebene und in Fig. 1 dargestellte erfindungsgemäße System ist auf besonders vorteilhafte und effektive Weise für einen vollautomatischen Startabbruch ausgebildet. Ein durch das Beenden der Betätigung des Startschalters 8 eingeleiteter Startabbruch erzeugt ein entsprechendes Startabbruchsignal und führt dieses der Steuerungseinrichtung 24, insbesondere der Einrücksteuerung 14, der Einspritzsteuerung 16 und der Zündsteuerung 18 sowie einem Zeitverzögerungsglied bzw. Timer 26 zu. Das Startabbruchsignal veranlaßt im wesentlichen augenblicklich, daß die Einspritzsteuerung 16 und die Zündsteuerung 18 ein jeweiliges Steuersignal erzeugen und dieses der Einspritzanlage 20 bzw. der Zündanlage 22 zuführen. Infolge dieser Signale wird eine weitere Zufuhr des Kraftstoff-Luft-Gemisches von der Einspritzanlage 20 unterbunden und die Zündausgabe der Zündanlage 22 unterdrückt. Gleichzeitig verursacht das dem Timer 26 zugeführte Startabbruchsignal, daß der Anlasser 2 nicht augenblicklich beim Einleiten des Startabbruchs abgeschaltet wird, sondern eine vorbestimmte Zeit weiter mit Energie versorgt wird. Darüber hinaus wird das Startabbruchsignal durch den Timer 26 zeitverzögert an die Einrücksteuerung 14 weitergeleitet (in Fig. 1 durch eine gestrichelte Linie dargestellt), auf dessen Basis ein Steuersignal zum Ausrücken der Einrückeinrichtung 6 an die Betätigungseinrichtung 12 ausgegeben wird. Diese durch den Timer 26 bewirkte Zeitverzögerung kann entweder gleich der Zeit bis zum Abschalten des Anlassers 2 oder davon unterschiedlich sein.The system according to the invention described above and shown in FIG. 1 is in a particularly advantageous and effective way for a fully automatic start abort educated. One initiated by ending the operation of the start switch 8 Start abort generates a corresponding start abort signal and carries this out Control device 24, in particular the engagement control 14, the injection control 16 and the ignition controller 18 and a time delay element or timer 26 to. The start abort signal essentially causes the injection control 16 and the ignition control 18 generate a respective control signal and this feed the injection system 20 or the ignition system 22. As a result of these signals a further supply of the fuel-air mixture from the injection system 20 is prevented and suppresses the ignition output of the ignition system 22. Caused at the same time the start abort signal supplied to the timer 26 that the starter 2 is not instantaneous is switched off when initiating the start abort, but a predetermined one Time is supplied with energy. In addition, the start abort signal forwarded to the engagement controller 14 with a time delay by the timer 26 (in FIG. 1 represented by a broken line), on the basis of which a control signal for disengagement of the engagement device 6 is output to the actuating device 12. This time delay caused by the timer 26 can either equal the time to to switch off the starter 2 or be different.

Die vorgegebene Zeitdauer bis zum Abschalten des Anlassers 2 und die Zeitdauer bis zum Auskuppeln der Einspureinrichtung 6 ist dabei so ausgewählt, daß der Anlasser 2 erst gestoppt und die Einspureinrichtung 6 ausgerückt wird, wenn keine Gemischentflammung mehr erfolgen kann. Im Anschluß daran wird die Steuerungseinrichtung 24 in erneute Startbereitschaft versetzt.The predetermined time until the starter 2 is switched off and the time until for disengaging the single-track device 6 is selected so that the starter 2 only stopped and the single-track device 6 is disengaged when there is no ignition of the mixture more can be done. Subsequently, the control device 24 in ready to start again.

Zusammenfassend ist festzustellen, daß das erfindungsgemäße System und Verfahren zum kontrollierten Startabbruch für einen Verbrennungsmotor dafür Sorge trägt, daß ein Rückdrehen des Motors 4 und ein Verbrennen des Kraftstoff-Luft-Gemisches im Bereich der Saugrohre unterbunden wird, wodurch die Gefahr der Beschädigung des Motors und/oder Fahrzeugs sowie das Verletzungsrisiko erheblich reduziert wird.In summary, it can be stated that the system and method according to the invention for controlled start abort for an internal combustion engine ensures that a The engine 4 turns back and the fuel-air mixture burns in the area the intake manifold is prevented, reducing the risk of damage to the engine and / or vehicle and the risk of injury is significantly reduced.
