Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Steuern der Aufheizung der Glühkerzen eines Dieselmotors nach dem Gattungsbegriff des Patentanspruchs 1 bzw. Patentanspruchs 3.The invention relates to a method and a device for controlling the heating of the glow plugs of a diesel engine according to the preamble of claim 1 or patent claim 3.
Ein derartiges Verfahren und eine derartige Vorrichtung, die aus der US-A-6,148,258 bzw. der US-A-5,507,255 bekannt sind, dienen dazu, die Glühkerzen auf eine Solltemperatur zu bringen, bei der der Motor gestartet werden kann.Such a method and apparatus, known from US-A-6,148,258 and US-A-5,507,255 respectively, serve to bring the glow plugs to a desired temperature at which the engine can be started.
Aus MTZ 10/2000 "Das elektronisch gesteuerte Glühsystem ISS für Dieselmotoren" ist ein Verfahren zum Steuern der Aufheizung der Glühkerzen eines Diesemotors bekannt, bei dem der Glühbefehl oder die Glühanforderung nach abgeschlossener Initialisierung der Motorsteuerung, nach erfolgter Bestimmung der Temperatur der Motorelemente über die Motorsteuerung und anschließendem erfolgreichen Aufbau einer Kommunikation zwischen der Motorsteuerung und dem Glühsteuergerät gegeben wird.From MTZ 10/2000 "The electronically controlled glow system ISS for diesel engines" is known a method for controlling the heating of the glow plugs of a diesel engine, wherein the glow command or Glühanforderung after completion of the initialization of the engine control, after determining the temperature of the engine elements via the engine control and then successfully establishing communication between the engine controller and the glow controller.
Da bei diesem Verfahren die Motorsteuerung erst nach erfolgter Initialisierung einen Glühbefehl an das Glühsteuergerät abgeben kann, wird durch die Zeit der Initialisierung der Motorsteuerung und der Befehlsübertragung die Aktivierung der Glühkerzen, das heißt der Beginn der Aufheizung der Glühkerzen verzögert, so daß viel Zeit bis zu den ersten erfolgreichen Zündungen des Motors vergeht.Since in this method, the engine control can issue an annealing command to the Glühsteuergerät only after initialization, the activation of the glow plugs, that is the beginning of the heating of the glow plugs is delayed by the time of initialization of the engine control and command transmission, so that much time up to the first successful ignition of the engine passes.
Es ist auch vorgeschlagen worden, das Öffnen der Türen des Fahrzeuges, das mit dem Dieselmotor ausgerüstet ist, als Startsignal für das Aufheizen der Glühkerzen zu nutzen. Dieses Verfahren hat jedoch den Nachteil, daß das Öffnen der Türen oft nicht mit einem gewünschten Motorstart verbunden ist und daher die Anzahl der Aufheizvorgänge der Glühkerzen unnötig erhöht und deren Lebensdauer reduziert wird.It has also been proposed to use the opening of the doors of the vehicle, which is equipped with the diesel engine, as a start signal for the heating of the glow plugs. However, this method has the disadvantage that the opening of the doors is often not associated with a desired engine start and therefore unnecessarily increases the number of heating operations of the glow plugs and their life is reduced.
Die der Erfindung zugrunde liegende Aufgabe besteht demgegenüber darin, ein Verfahren und eine Vorrichtung der eingangs genannten Art anzugeben, mit denen die für die Aufheizung der Glühkerzen benötigte Zeit verringert werden kann.The object of the invention is based on the object to provide a method and an apparatus of the type mentioned, with which for the heating of the glow plugs required time can be reduced.
Diese Aufgabe wird gemäß der Erfindung durch das Verfahren nach dem Patentanspruch 1 und die Vorrichtung nach dem Patentanspruch 3 gelöst.This object is achieved according to the invention by the method according to claim 1 and the device according to claim 3.
Bei dem erfindungsgemäßen Verfahren und der erfindungsgemäßen Vorrichtung wird erforderlichenfalls mit der Aufheizung der Glühkerzen unmittelbar auf ein Signal zum Starten des Motors, z. B. nach dem Anschalten der Zündung begonnen, nachdem die Motortemperatur ermittelt und zu einem Glühbefehl ausgewertet worden ist. Da somit der erfolgreiche Abschluß der Initialisierung der Motorsteuerung nicht abgewartet werden muß und die Temperaturermittlung unabhängig von der Motorsteuerung selbständig von der Glühsteuerung durchgeführt wird, läßt sich die zum Aufheizen der Glühkerzen benötigte Zeit im typischen Fall um beispielsweise 500 ms reduzieren.In the method and apparatus of the invention, if necessary, with the heating of the glow plugs directly to a signal to start the engine, for. B. after switching on the ignition started after the engine temperature has been determined and evaluated to a Glühanmehl. Since, therefore, the successful completion of the initialization of the engine control does not have to wait and the temperature determination is carried out independently of the engine control independently of the annealing control, the time required to heat the glow plugs can typically be reduced by, for example, 500 ms.
Bevorzugte Weiterbildungen und Ausgestaltungen des erfindungsgemäßen Verfahren und der erfindungsgemäßen Vorrichtung sind Gegenstand der Patentansprüche 2 und 4 bis 6.Preferred developments and refinements of the method according to the invention and the device according to the invention are the subject of
Im Folgenden wird anhand der zugehörigen Zeichnungen ein besonders bevorzugtes Ausführungsbeispiel des erfindungsgemäßen Verfahrens und der erfindungsgemäßen Vorrichtung näher beschrieben.In the following, a particularly preferred embodiment of the method according to the invention and the device according to the invention will be described in detail with reference to the accompanying drawings.
Es zeigen
- Figur 1 eine perspektivische Ansicht der Anordnung eines Glühsteuergerätes im Motorraum eines Dieselmotors und
Figur 2 in einem Zeitdiagramm ein Beispiel des erfindungsgemäßen Verfahrens.
- Figure 1 is a perspective view of the arrangement of a Glühsteuergerätes in the engine compartment of a diesel engine and
- FIG. 2 shows a time diagram of an example of the method according to the invention.
Wie es in Figur 1 dargestellt ist, umfaßt die erfindungsgemäße Vorrichtung zum Steuern der Aufheizung der Glühkerzen eines Dieselmotors eine Glühsteuerung 1, die einen Glühbefehl zum Aufheizen der Glühkerzen erzeugt, wenn die Motortemperatur unter einem vorgegebenen Wert liegt. Zum Ermitteln der Motortemperatur ist bei dem in Figur 1 dargestellten Ausführungsbeispiel ein interner, in der Glühsteuerung 1 vorgesehener Temperatursensor vorgesehen, der die Glühsteuerschaltungsträgertemperatur ermittelt, die gleich der Temperatur einer Kontaktfläche, beispielsweise des Bodenbleches des Gehäuses der Glühsteuerung 1, ist, mit dem die Glühsteuerung 1 direkt am Motorblock 2 thermisch mit dem Motor verbunden angeordnet ist. Das Ausgangssignal des Temperatursensors entspricht daher der Motortemperatur.As shown in FIG. 1, the diesel engine glow plug heating control apparatus according to the present invention comprises an ignition controller 1 which generates a glow command for heating the glow plugs when the engine temperature is below a predetermined value. In order to determine the engine temperature, in the exemplary embodiment illustrated in FIG. 1, an internal temperature sensor is provided which determines the annealing control circuit carrier temperature which is equal to the temperature of a contact surface, for example the bottom plate of the housing of the annealing control 1, with which the annealing control 1 is arranged directly on the
In Abhängigkeit von diesem Temperaturwert entscheidet die Glühsteuerung 1 selbständig, ob mit dem Aufheizen der Glühkerzen begonnen wird oder nicht.Depending on this temperature value, the annealing control 1 decides independently whether to start heating the glow plugs or not.
Alternativ zu der Verwendung eines internen Temperatursensors kann auch ein externer Temperatursensor an einer entsprechenden Stelle im Motorraum angebracht sein, so daß er einen Wert ermittelt, der eine Aussage über die Motortemperatur ermöglicht. Das Ausgangssignal dieses externen Temperatursensors liegt dann an der Glühsteuerung. Die Verwendung eines internen Temperatursensors ist jedoch wegen der Einsparung eines weiteren externen Sensors und seiner Verkabelung sowie aufgrund der guten thermischen Kopplung zwischen der Glühsteuerung und dem Motor bevorzugt.As an alternative to the use of an internal temperature sensor, an external temperature sensor may be mounted at a corresponding location in the engine compartment so that it determines a value that allows a statement about the engine temperature. The output of this external temperature sensor is then at the glow control. However, the use of an internal temperature sensor is because of the saving of another external sensor and its wiring as well preferred due to the good thermal coupling between the glow control and the motor.
Die Arbeit der oben beschriebenen Vorrichtung zum Steuern der Aufheizung der Glühkerzen beginnt beim Anliegen eines Startsignals, z. B. wenn die Zündung des Motors eingeschaltet wird. Somit kann mit der Aufheizung der Glühkerzen bei kaltem Motor schon während der Initialisierungszeit der Motorsteuerung begonnen werden. Die elektrische Versorgung der Glühsteuerung erfolgt über einen entsprechenden Anschluß, beispielsweise die Klemme 15, wobei die Tatsache, daß an dieser Klemme eine Spannung liegt, als Startsignal oder Betriebsbeginn interpretiert werden kann. Es kann aber auch ein dezidiertes Startsignal verwandt werden, das bei der Anschaltung der Zündung erzeugt wird.The work of the above-described device for controlling the heating of the glow plugs begins when applying a start signal, for. B. when the ignition of the engine is turned on. Thus, the heating of the glow plugs with cold engine already during the initialization time of the engine control can be started. The electrical supply of the Glühsteuerung via a corresponding terminal, such as the terminal 15, wherein the fact that at this terminal is a voltage can be interpreted as a start signal or start of operation. However, it is also possible to use a dedicated start signal, which is generated when the ignition is switched on.
Wenn ein derartiges Startsignal anliegt und die von dem Sensor ermittelte Motortemperatur unter einem vorgegebenen Wert von beispielsweise 5° Celsius liegt, wird das Aufheizen von der Glühsteuerung selbstätig ausgelöst. Durch ein dezidiertes Startsignal, beziehungsweise der Tatsache, daß an der Versorgungsklemme für die Glühsteuerung eine Spannung liegt, wird sichergestellt, daß mit dem Aufheizen der Glühkerzen nur dann begonnen wird, wenn tatsächlich das Starten des Motors beabsichtigt ist.If such a start signal is present and the engine temperature determined by the sensor is below a predetermined value of, for example, 5 ° Celsius, the heating is automatically triggered by the ignition control. By a dedicated start signal, or the fact that there is a voltage at the supply terminal for the annealing control, it is ensured that the heating of the glow plugs is only started when the starting of the engine is actually intended.
Im Folgenden wird anhand von Figur 2 ein Beispiel des Ablaufes des erfindungsgemäßen Verfahrens näher beschrieben.An example of the sequence of the method according to the invention will be described in more detail below with reference to FIG.
Wie es in Figur 2 in einem Zeitdiagramm dargestellt ist, wird mit dem Aufheizen der Glühkerzen durch die Glühsteuerung automatisch begonnen, wenn der vom Temperatursensor ermittelte Wert der Motortemperatur den vorgegebenen Wert von beispielsweise 5° Celsius unterschreitet und ein Startsignal anliegt. Der Aufheizvorgang beginnt somit schon während der Initialisierungsphase der Motorsteuerung, da für die Temperaturermittelung wesentlich weniger Zeit als für die Initialisierung der Motorsteuerung benötigt wird.As shown in FIG. 2 in a time diagram, the heating of the glow plugs is automatically started by the annealing control when the value of the engine temperature determined by the temperature sensor falls below the predetermined value of, for example, 5 ° Celsius and a start signal is applied. The heating process thus already begins during the initialization phase of the engine control, since much less time is required for the temperature determination than for the initialization of the engine control.
Wie es in Figur 2 weiterhin dargestellt ist, wird die Steuerung der Aufheizung der Glühkerzen nach erfolgreichem Abschluß der Initialisierung der Motorsteuerung von dieser übernommen, sobald eine Kommunikation zwischen der Motorsteuerung und der Glühsteuerung aufgebaut ist. Das Aufheizen der Glühkerzen wird dann durch Befehle der Motorsteuerung beendet oder neu definiert. Falls das nicht der Fall ist, das heißt, wenn die Initialisierung der Motorsteuerung nicht erfolgreich abgeschlossen werden konnte und/oder keine Kommunikation zur Glühsteuerung aufgebaut wurde, wird der Aufheizvorgang nach einer bestimmten Zeit selbstätig beendet. Für die Umschaltung zwischen der Steuerung der Aufheizung durch Glühsteuerung und die Motorsteuerung ist ein entsprechendes Umschaltglied vorgesehen, die Beendigung des Aufheizen der Glühkerze nach einer bestimmten Zeitintervall wird über ein dementsprechendes Zeitglied gesteuert.As further shown in Figure 2, the control of the heating of the glow plugs after successful completion of the initialization of the engine control is taken from this, once a communication between the engine control and the glow control is constructed. The heating of the glow plugs is then terminated or redefined by engine control commands. If this is not the case, that is, if the initialization of the engine control could not be completed successfully and / or no communication was established for the glow control, the heating process is automatically terminated after a certain time. For the switching between the control of the heating by Glühsteuerung and the engine control a corresponding switching element is provided, the completion of the heating of the glow plug after a certain time interval is controlled by a corresponding timer.
Es ist bevorzugt, daß zur Optimierung des Anlassens des Motors nach der Aufnahme der Kommunikation zwischen der Motorsteuerung und der Glühsteuerung der aktuelle Zustand der Glühkerzen an die Motorsteuerung rückgemeldet wird, so daß die Motorsteuerung dann unter Einbeziehung weiterer Faktoren darüber entscheidet, ob ein Anlassen des Motors ausgelöst wird oder ob noch abgewartet wird, bis die Glühkerzen eine bestimmte Temperatur von beispielsweise 800° Celsius mit Sicherheit erreicht haben.It is preferred that for optimizing the starting of the engine after commencement of the communication between the engine control and the glow control, the current state of the glow plugs is fed back to the engine controller so that the engine controller then decides whether or not to start the engine, taking into account other factors is triggered or whether it is still waiting until the glow plugs have reached a certain temperature, for example, 800 ° C with certainty.
Der oben beschriebene Betriebsablauf wird im Folgenden anhand eines konkreten Beispiels näher erläutert:The operating sequence described above is explained in more detail below with reference to a concrete example:
Der Fahrer eines Fahrzeuges erzeugt mit seinem Zündschlüssel beim Anschalten der Zündung ein Motorstartsignal. Dieses Signal kann auch in anderer Weise erzeugt werden. Dieses Signal kann beispielsweise darin bestehen, daß am Versorgungsanschluß zur Aktivierung des Anlassers des Motors, der Motorsteuerung und anderer Komponenten eine Spannung liegt. Es kann aber auch ein dezidiertes Startsignal sein, das an der Motorsteuerung, der Glühsteuerung und weiteren Komponenten liegt. Dieses Signal wird ausgewertet und nach Ablauf von Überprüfungsroutinen wird ein dem aktuellen Zustand des Motors angepaßter Anlaßvorgang durchgeführt. Das Startsignal liegt nicht nur an der Motorsteuerung sondern auch an der Glühsteuerung. Diese wird dadurch initialisiert und ermittelt anschließend die aktuelle Temperatur des Motors entweder über einen intern eingebauten Temperatursensor oder über einen externen Temperatursensor, der zum Beispiel im Motorblock in Kontakt mit dem Kühlwasser eingebaut sein kann. Wird ein interner Temperatursensor verwendet, ist es vorteilhaft, eine gute thermische Kopplung zwischen der Glühsteuerung und dem Motor herbeizuführen, indem beispielsweise die Glühsteuerung mit ihrer Metallbodenplatte am Motorblock angebracht ist. Wird der in der Glühsteuerung vorgegebene Wert für die Motortemperatur von beispielsweise 5° Celsius unterschritten, löst die Glühsteuerung unmittelbar das Aufheizen der Glühkerzen aus. Während die Glühkerzen bereits bestromt werden, wird gleichzeitig die Motorsteuerung initialisiert, so daß sie nach Ablauf der Überprüfungsroutinen die Kraftstoffeinspritzung beziehungsweise das Anlassen des Motors freigibt.The driver of a vehicle generates an engine start signal with its ignition key when the ignition is switched on. This signal can also be generated in other ways. This signal may be, for example, that there is a voltage at the supply terminal for activating the starter motor, the motor control and other components. But it can also be a dedicated start signal, the at the engine control, the glow control and other components is located. This signal is evaluated and after elapse of verification routines, a starting process adapted to the current state of the engine is performed. The start signal is not only due to the engine control but also to the glow control. This is then initialized and then determines the current temperature of the engine either via an internally installed temperature sensor or via an external temperature sensor, which may be installed, for example in the engine block in contact with the cooling water. If an internal temperature sensor is used, it is advantageous to bring about a good thermal coupling between the annealing control and the motor, for example by the annealing control with its metal bottom plate attached to the engine block. If the predetermined value for the engine temperature of, for example, 5 ° Celsius is exceeded in the glow control, the glow control immediately triggers the heating of the glow plugs. While the glow plugs are already being energized, at the same time the engine control is initialized so that it releases the fuel injection or the engine start after the end of the check routines.
Im typischen Fall benötigt die Motorsteuerung für ihre Initialisierung eine Zeit, die um 300 bis 500 ms länger als die Initialisierungszeit der Glühsteuerung ist. Diese Zeit kann somit bei der Aufheizung der Glühkerzen eingespart werden. Nach Abschluß der Initialisierung der Motorsteuerung kann die Motorsteuerung mit der Glühsteuerung kommunizieren und die weiteren Befehle für das Aufheizen der Glühkerzen an die Glühsteuerung übermitteln. Es ist weiterhin möglich, daß der Zustand der Glühkerzen abgefragt wird und das Anlassen des Motors beispielsweise erst dann durch die Motorsteuerung freigegeben wird, wenn die Glühkerzen eine Temperatur von zum Beispiel 800° Celsius mit Sicherheit überschritten haben. In dieser Weise kann das Anlaßverhalten bezüglich der Anlaßzeit, der Schadstoffemission u.s.w. optimiert werden. Sollte bei Vorliegen eines Startsignals kein weiterer Befehl von der Motorsteuerung kommen, schaltet die Glühsteuerung das Aufheizen der Glühkerzen nach einer in der Glühsteuerung vorgegebenen Zeit von beispielsweise 20 s wieder aus.Typically, the motor controller requires a time for its initialization which is 300 to 500 ms longer than the initialization time of the glow control. This time can thus be saved in the heating of the glow plugs. Upon completion of the engine control initialization, the engine controller may communicate with the glow control and transmit the further commands for heating the glow plugs to the glow control. It is also possible that the state of the glow plugs is queried and the starting of the engine, for example, is released by the engine control, when the glow plugs have exceeded a temperature of, for example, 800 ° C with certainty. In this way, the starting behavior with respect to the starting time, the pollutant emission, etc. are optimized. If, in the presence of a start signal, no further command comes from the engine control, the glow control switches off the heating of the glow plugs after a time specified in the glow control of, for example, 20 s.
Bei dem erfindungsgemäßen Verfahren und der erfindungsgemäßen Vorrichtung kann die Zeit verkürzt werden, die bis zu der ersten erfolgreichen Zündung des Dieselmotors bei seinem Kaltstart bei Verwendung einer Glühsteuerung insbesondere beim direkten Anlassen des Motors ohne explizites Vorglühen vergeht. Während dieser Zeit wird das Bordnetz des Fahrzeuges nur durch die Aufheizung der Glühkerzen und gegebenenfalls den Anlasser belastet. Durch eine schnelle Reduktion des Strombedarfs bei einem Glühsystem mit selbstregelnden Glühkerzen wird das Bordnetz in der Startphase entlastet. Es ist weiterhin ein emissionsärmeres Anlassen mit dem Zündschlüssel, das heißt ein Anlassen ohne explizites Vorglühen möglich, da insbesondere weniger unverbrannte Kraftstoffe im Abgasstrahl auftreten. Die Lebensdauer der Glühkerzen kann durch eine Verringerung der Aufheizvorgänge auf das notwendige Maß im Gegensatz zu den Verfahren erhöht werden, bei denen der Aufheizvorgang bereits beim Öffnen einer Fahrzeugtür ausgelöst wird. Das Anlassen des Motors kann weiterhin in Hinblick auf die Anlaßfreigabe erst nach Erreichen einer bestimmten Temperatur optimiert werden. Falls der Motor über den Zündschlüssel nicht angelassen werden soll oder dieser Wunsch nach Anlassen des Motors unterdrückt wird, kann mit der gewonnenen Zeitspanne das Aufheizen der Glühkerzen moderater durchgeführt werden.In the method and the device according to the invention, the time can be shortened, which passes until the first successful ignition of the diesel engine at its cold start when using an annealing control in particular when directly starting the engine without explicit preheating. During this time, the electrical system of the vehicle is charged only by the heating of the glow plugs and possibly the starter. By quickly reducing the power consumption of an annealing system with self-regulating glow plugs, the on-board electrical system is relieved during the starting phase. It is also a low-emission starting with the ignition key, that is a starting without explicit preheating possible because in particular less unburned fuels occur in the exhaust stream. The life of the glow plugs can be increased by reducing the heating operations to the necessary level in contrast to the methods in which the heating is already triggered when opening a vehicle door. The starting of the engine can still be optimized in terms of the annealing release after reaching a certain temperature. If the engine is not to be started by the ignition key or this request for starting the engine is suppressed, the heating time of the glow plugs can be made more moderate with the obtained time.

- Device for controlling the heating of the glow plugs in a diesel engine, having a glow control system which, upon a signal to start the engine, generates a glow command for heating the glow plugs if the engine temperature lies below a predetermined value, and having a temperature sensor which is independent of the engine control system, said temperature sensor determining the engine temperature and its output signal being applied to the glow control system, characterised by a switch-over apparatus for switching over from issuing of the glow command by the glow control system to issuing of the glow command by the engine control system, which responds on conclusion of the initialising of the engine control system and starting of communication between the engine control system and the glow control system.
- Device according to claim 3, characterised in that the temperature sensor is arranged such that it determines the temperature of the glow control circuit carrier, which is brought into thermal contact with the engine.
- Device according to claim 3, characterised in that an external temperature sensor separate from the glow control system is provided.
- Device according to claim 3, characterised in that a time member which, given a lack of communication between the engine control system and the glow control system, cancels the glow command following expiry of a predetermined time interval.
