Abstract

The ignition current is supplied through a high-voltage (HV) distributor (1) to the four cylinders (Z1-Z4) of a four-stroke engine. A misfire detector (F) identifies the cylinder (Z1) which should have been fired at top dead centre (OT), and permits identification of the cylinder (Z3) needing to be fired next after about 180 deg. O in the first of the two crankshaft revolutions. The particular cylinder can be chosen at random from the beginning so that cylinder identification can be performed without provoking any misfire. When a misfire is detected in any cylinder, that cylinder is accepted as the particular one.

Description

Die Erfindung bezieht sich auf eine Vorrichtung zur elektronischen Zündsteuerung bei Brennkraftmaschinen in Kraftfahrzeugen nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for electronic ignition control in internal combustion engines in motor vehicles according to the preamble of patent claim 1.

vollelektronischen Zündung" wird eine ruhende Hochspannungsverteilung vorgenommen. Für eine ruhende Hochspannungsverteilung sind Mehrtunken-Zündspulen und Einzelfunken-Zündspulen bekannt. Insbesondere durch den Einsatz von Einzelfunken-Zündspulen ist eine zylinderselektive ruhende Hochspannungsverteilung möglich. Hierbei ist jedem Zylinder der Brennkraftmaschine eine eigene Zündspule zugeordnet. Für eine zylinderselektive ruhende Hochspannungsverteilung ist daher eine Zylindererkennung notwendig. Die Problematik der Zylindererkennung ergibt sich insbesondere durch den Einsatz von einem Viertakt-Ottomotor als Brennkraftmaschine, da der Viertakt-Motor für ein Arbeitsspiel zwei Kurbelwellenumdrehungen benötigt. Zwar ist durch den Kurbelwellenwinkelgeber eine eingeschränkte Zylindererkennung möglich, jedoch können die Zylinder, die innerhalb einer Kurbelwellenumdrehung den gleichen Kurbelwellenwinkel aufweisen, nicht unterschieden werden. Befinden sich beispielsweise zwei Zylinder am oberen Totpunkt, liegt für einen Zylinder der Verdichtungstakt und für den anderen Zylinder der Ausstoßtakt vor. Für eine elektronische Zündsteuerung ist jedoch die Erkennung des Zylinders notwendig, der sich gerade im Verdichtungstakt befindet.For example from the textbook

fully electronic ignition ", a static high-voltage distribution is carried out. Multi-spark ignition coils and single spark ignition coils are known for a static high voltage distribution. A cylinder-selective static high voltage distribution is possible in particular through the use of single spark ignition coils. Each cylinder of the internal combustion engine is assigned its own ignition coil. For A cylinder-selective static high-voltage distribution is therefore necessary for cylinder detection in particular through the use of a four-stroke gasoline engine as an internal combustion engine, since the four-stroke engine requires two crankshaft revolutions for one work cycle. Restricted cylinder detection is possible by means of the crankshaft angle sender, but the cylinders which have the same crankshaft angle within one crankshaft revolution cannot be distinguished. For example, if there are two cylinders at top dead center, there is the compression stroke for one cylinder and the exhaust stroke for the other cylinder. For electronic ignition control, however, it is necessary to recognize the cylinder that is currently in the compression stroke.

Hierzu sind elektronische Zündsteuerungssysteme bekannt, die mittels zusätzlicher Sensorvorrichtungen, z. B. mittels eines Nockenwellenstellungsgebers, einen bestimmten Zylinder innerhalb einer Kurbelwellenumdrehung erkennen können und somit eine vorgegebene zylinderselektive Zündfolge bestimmen können.For this purpose, electronic ignition control systems are known, which by means of additional sensor devices, for. B. by means of a camshaft position sensor, a specific cylinder within a crankshaft revolution and thus can determine a predetermined cylinder-selective firing order.

Es ist Aufgabe der Erfindung, eine Zylindererkennung unabhängig von einer zusätzlichen Sensorvorrichtung vornehmen zu können, wenn entweder ein Ausfall der zusätzlichen Sensorik vorliegt oder eine derartige Sensorik nicht vorhanden ist.It is an object of the invention to be able to carry out cylinder detection independently of an additional sensor device if either there is a failure of the additional sensor system or if such a sensor system is not present.

Diese Aufgabe wird durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.
Erfindungsgemäß ist die Hochspannungsverteilungseinheit derart ausgestaltet, daß zur Zylindererkennung zunächst ein beliebiger Zylinder als ein bestimmter Zylinder angenommen wird, daß dieser Zylinder zu dem für den bestimmten Zylinder vorgegebenen Zeitpunkt gezündet wird und daß anschließend im Falle einer Erkennung eines Zündaussetzers bei einem anderen Zylinder dieser andere Zylinder als der bestimmte Zylinder angenommen wird.
Zwar kann durch die erfindungsgemäße Vorrichtung kurzzeitig eine fehlerhatte Zündsteuerung vorgenommen werden, jedoch führt diese Vorgehensweise zu einer sehr schnellen Zylindererkennung. Sie ist für den Fahrer kaum spürbar und ermöglicht einen kostengünstigen Ersatz einer zusätzlichen Sensorik oder einen komfortablen Notlauf bei Ausfall einer derartigen zusätzlichen Sensorik.This object is achieved by the characterizing features of patent claim 1.
According to the invention, the high-voltage distribution unit is designed in such a way that any cylinder is initially assumed to be a specific cylinder for cylinder recognition, that this cylinder is ignited at the time specified for the specific cylinder, and that if another misfire is detected then another Cylinder this other cylinder than the specific cylinder is assumed.
A faulty ignition control can be carried out briefly by the device according to the invention, but this procedure leads to very fast cylinder detection. It is barely noticeable to the driver and enables a cost-effective replacement of an additional sensor system or a comfortable emergency run in the event of failure of such an additional sensor system.

Üblicherweise werden zur elektronischen Zündsteuerung Kurbelwellenstellungsgeber bzw. Kurbelwellenwinkelgeber verwendet, die eine Erkennungsmarke des oberen Totpunktes eines bestimmten Zylinderpaares aufweisen. Ist ein derartiger Kurbelwellenstellungsgeber bei einer Vorrichtung zur elektronischen Zündsteuerung vorhanden, wird erfindungsgemäß bei einer geraden Zylinderanzahl als bestimmer Zylinder ein beliebiger Zylinder dieses Zylinderpaares, dem die Erkennungsmarke des oberen Totpunktes zugeordnet ist, angenommen. Somit ist für die zylinderselektive ruhende Hochspannungsverteilung lediglich der Zylinder dieses Zylinderpaares herauszufinden, der sich beim oberen Totpunkt während der gerade vorliegenden Kurbelwellenumdrehung im Verdichtungs- bzw. Zündungs-Takt befindet. Ist dieser Zylinder herausgefunden worden, ist die Bestimmung der zylinderselektiven Zündfolge allein durch die Zylinderanzahl der Brennkraftmaschine und durch den Kurbelwellenstellungsgeber - wie bekannt - bestimmbar.Usually, crankshaft position sensors or crankshaft angle sensors are used for electronic ignition control, which have an identification mark of the top dead center of a specific cylinder pair. If such a crankshaft position transmitter is present in a device for electronic ignition control, any cylinder of this pair of cylinders, to which the identification mark of the top dead center is assigned, is assumed as the specific cylinder for an even number of cylinders. Thus, for the cylinder-selective static high-voltage distribution, only the cylinder of this pair of cylinders has to be found, which is at compression stroke or ignition timing at top dead center during the crankshaft revolution that is currently taking place. If this cylinder has been found out, the determination of the cylinder-selective ignition sequence can be determined solely by the number of cylinders of the internal combustion engine and by the crankshaft position transmitter, as is known.

Eine vorteilhafte Ausgestaltung der Erfindung ist der Gegenstand des Patentanspruchs 2.
Erfindungsgemäß wird ein Zündaussetzer durch eine ohnehin vorhandene Zündaussetzer-Erkennungseinheit festgestellt.An advantageous embodiment of the invention is the subject of claim 2.
According to the invention, a misfire is determined by an misfire detection unit that is present anyway.

In elektronischen Steuergeräten, in denen üblicherweise auch die elektronische Zündsteuerung integriert ist, wird für Fehlererkennungs- und Diagnosezwecke ohnehin eine Zündaussetzer-Erkennungseinheit vorgesehen. Mittels dieser ohnehin vorhandenen Zündaussetzer-Erkennungseinheit wird der gesuchte bestimmte Zylinder auf einfache Weise erkannt, wenn der als bestimmter Zylinder angenommene beliebige Zylinder nicht bereits der bestimmte bzw. gesuchte Zylinder, der sich gerade im Verdichtungstakt befindet, ist. Hierdurch ist die erfindungsgemäße Vorrichtung besonders einfach und kostengünstig realisierbar.In electronic control devices, in which the electronic ignition control is usually also integrated, a misfire detection unit is provided anyway for fault detection and diagnostic purposes. By means of this misfiring detection unit, which is present anyway, the specific cylinder sought is identified in a simple manner if the arbitrary cylinder adopted as the specific cylinder is not already the specific or sought cylinder that is currently in the compression stroke. As a result, the device according to the invention is particularly simple and inexpensive to implement.

In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt. Sie zeigt die erfindungsgemäße Vorrichtung am Beispiel eines Vierzylinder-Viertakt-Ottomotors.In the drawing, an embodiment of the invention is shown. It shows the device according to the invention using the example of a four-cylinder, four-stroke gasoline engine.

Die Figur zeigt schematisch eine Hochspannungsverteilungseinheit 1 zur zylinderselektiven ruhenden Hochspannungsverteilung bei einer elektronischen Zündsteuerung für vier Zylinder Z1, Z2, Z3, Z4. Die übliche Zündfolge einer Vierzylinder-Brennkraftmaschine bei Viertakt-Ottomotoren ist die Zündung des Zylinders Z1 bei einem Kurbelwellenwinkel KW von ca. 0°, die Zündung des Zylinders Z3 bei ca. 180° KW, die Zündung des Zylinders Z4 bei ca. 360° KW und die Zündung des Zylinders Z2 bei ca. 540° KW. Das Arbeitsspiel eines Zylinders bzw. die Zündung aller Zylinder findet innerhalb von zwei Kurbelwellenumdrehungen statt. Während jeder Kurbelwellenumdrehung wird einmal die Marke des Kurbelwellenstellungsgebers für den oberen Totpunkt OT des Zylinderpaares Z1 und Z4 bei etwa 0 bzw. 360° KW erfaßt. Durch die Hochspannungsverteilungseinheit 1 muß festgestellt werden, welcher der beiden Zylinder Z1 und Z4 am oberen Totpunkt OT sich gerade im Verdichtungstakt und welcher sich gerade im Ausstoßtakt befindet.The figure schematically shows a high-voltage distribution unit 1 for cylinder-selective, stationary high-voltage distribution in an electronic ignition control for four cylinders Z1, Z2, Z3, Z4. The usual firing sequence of a four-cylinder internal combustion engine in four-stroke gasoline engines is the ignition of cylinder Z1 at a crankshaft angle KW of approximately 0 °, the ignition of cylinder Z3 at approximately 180 ° KW, and the ignition of cylinder Z4 at approximately 360 ° KW and the ignition of the cylinder Z2 at approx. 540 ° KW. The working cycle of a cylinder or the ignition of all cylinders takes place within two revolutions of the crankshaft. During each revolution of the crankshaft, the mark of the crankshaft position transmitter for the top dead center OT of the pair of cylinders Z1 and Z4 is detected at approximately 0 and 360 ° KW. The high-voltage distribution unit 1 must determine which of the two cylinders Z1 and Z4 at top dead center OT is currently in the compression stroke and which is currently in the exhaust stroke.

Üblicherweise wird bei elektronischen Zündsteuerungssystemen durch die Hochspannungsverteilungseinheit 1 eine Doppelzündung ausgeführt, solange eine Unterscheidung zwischen dem Verdichtungstakt und dem Ausstoßtakt und damit eine eindeutige Zylindererkennung noch nicht möglich ist. Bei bekannten elektronischen Zündsteuerungssystemen mit einer zusätzlichen Sensorvorrichtung zur Zylindererkennung, z. B. mit einem Nockenwellenstellungsgeber, wird diese Doppelzündung auch ausgeführt, wenn diese zusätzliche Sensorvorrichtung ausgefallen ist. Die erfindungsgemäße Vorrichtung kann entweder in dem Fall angewandt werden, wenn aufgrund eines Ausfalls der zusätzlichen Sensorvorrichtung zunächst eine Doppelzündung ausgeführt wird oder wenn eine zusätzliche Sensorvorrichtung nicht vorhanden ist. In beiden Fällen wird beim nächsten Erreichen der den Zylindern Z1 und Z4 zugeordneten OT-Marke des Kurbelwellenwinkelgebers angenommen, daß sich der Zylinder Z4 im Verdichtungstakt befindet bzw. daß der Zylinder Z4 der Zylinder Z1 ist. Tatsächlich befindet sich jedoch der Zylinder Z1 im Verdichtungstakt, bei dem gezündet werden müßte. Der Zylinder Z4 wird daraufhin im Ausstoßtakt zu dem für den Zylinder Z1 vorgegebenen Zeitpunkt bzw. Kurbelwellenwinkel gezündet, während der Zylinder Z1 nicht gezündet wird.In electronic ignition control systems, the high-voltage distribution unit 1 usually executes double ignition as long as it is not yet possible to distinguish between the compression stroke and the exhaust stroke and thus a clear cylinder detection. In known electronic ignition control systems with an additional sensor device for cylinder detection, e.g. B. with a camshaft position sensor, this double ignition is carried out even if this additional sensor device has failed. The device according to the invention can be used either in the event that double ignition is initially carried out due to a failure of the additional sensor device or if an additional sensor device is not present. In both cases, the next time the TDC mark of the crankshaft angle sensor assigned to the cylinders Z1 and Z4 is reached, it is assumed that the cylinder Z4 is in the compression stroke or that the cylinder Z4 is the cylinder Z1. Actually, however, cylinder Z1 is in the compression stroke, which would have to be ignited. The cylinder Z4 is then ignited in the exhaust stroke at the point in time or crankshaft angle specified for the cylinder Z1, while the cylinder Z1 is not ignited.

Über eine für die elektronische Zündsteuerung ohnehin vorhandene Zündaussetzer-Erkennungseinheit F zur Fehlererkennung wird daraufhin ein Zündaussetzer beim Zylinder Z1 erkannt. Über die Zündaussetzer-Erkennungseinheit F wird von der Hochspannungsverteilungseinheit 1 daraufhin erkannt, daß der Zylinder Z1 der bestimmte Zylinder ist, der richtigerweise bei der OT-Marke gezündet hätte werden müssen. Somit ist der Hochspannungsverteilungseinheit 1 auch bekannt, daß sie sich bezüglich der vorgegebenen Zündfolge in der ersten Kurbelwellenumdrehung befindet und daß ca. 180° nach dem oberen Totpunkt OT als nächstes der Zylinder Z3 gezündet werden muß. Da üblicherweise in der Hochspannungsverteilungseinheit 1 die vorgegebene Zündfolge bekannt ist, ist eine Erkennung jedes Zylinders möglich, sobald ein Zylinder als ein bestimmter Zylinder, in diesem Fall der Zylinder Z1, durch die Hochspannungsverteilungseinheit 1 identifiziert wurde. Ergänzend wird darauf hingewiesen, daß mit der erfindungsgemäßen Vorrichtung zufällig auch der als bestimmter Zylinder angenommene Zylinder von Anfang an der richtige Zylinder sein kann, wodurch zur Zylindererkennung kein Zündaussetzer provoziert werden muß. Ist beispielsweise eine ohnehin vorhandene Zündaussetzer-Erkennungseinheit F nicht vorhanden, kann die fehlerhafte Zündung beispielsweise auch durch einen Brennkraftmaschinendrehzahlabfall erkannt werden.An ignition misfire in cylinder Z1 is then detected via an ignition misfire detection unit F, which is present anyway for the electronic ignition control. The misfiring detection unit F then detects from the high-voltage distribution unit 1 that the cylinder Z1 is the specific cylinder that should have been correctly ignited at the TDC mark. Thus, the high-voltage distribution unit 1 is also known to be in the first crankshaft revolution with respect to the predetermined firing order and that 180 ° after top dead center TDC, cylinder Z3 must be fired next. Since the predetermined ignition sequence is usually known in the high-voltage distribution unit 1, it is possible to recognize each cylinder as soon as a cylinder has been identified by the high-voltage distribution unit 1 as a specific cylinder, in this case the cylinder Z1. In addition, it is pointed out that, with the device according to the invention, the cylinder assumed to be a specific cylinder can happen to be the correct cylinder right from the start, as a result of which no misfire has to be provoked for cylinder recognition. If, for example, a misfire detection unit F which is present anyway is not present, the faulty ignition can also be detected, for example, by a drop in the engine speed.

Die erfindungsgemäße Vorrichtung ermöglicht eine einfache und schnelle Zylindererkennung, mit der zusätzliche Sensorvorrichtungen eingespart werden können.The device according to the invention enables simple and quick cylinder recognition, with which additional sensor devices can be saved.
