Abstract
Description
Die Erfindung betrifft ein Verfahren und eine Vorrichtung zum Betreiben der Glühkerzen einer selbstzündenden Brennkraftmaschine.The invention relates to a method and a device for operating the glow plugs of a self-igniting internal combustion engine.
Es ist bekannt, die Glühkerzen einer selbstzündenden Brennkraftmaschine über ein Glühsteuergerät anzusteuern, d.h., mit entsprechendem Glühstrom zu versorgen, das mit der Motorsteuerung der Brennkraftmaschine verbunden ist. Die Glühkerzen einer Brennkraftmaschine sollten aber in Abhängigkeit von ihrem jeweiligen Typ, d.h., in Abhängigkeit davon, ob es sich beispielsweise um Stahl- oder Keramikglühkerzen handelt, auf der Grundlage unterschiedlicher Glühparameter angesteuert werden.It is known to control the glow plugs of a self-igniting internal combustion engine via an annealing control device, ie to supply it with a corresponding glow current, which is connected to the engine control of the internal combustion engine. However, the glow plugs of an internal combustion engine should be controlled on the basis of different annealing parameters, depending on their respective type, ie, depending on whether they are, for example, steel or ceramic glow plugs.
Um hier eine Optimierung zu erzielen war es bisher notwendig und üblich, dem Glühsteuergerät und/oder der Motorsteuerung den jeweiligen Kerzentyp vorzugeben, so dass in Abhängigkeit von dieser Vorgabe die Glühkerzen entsprechend angesteuert werden konnten.In order to achieve an optimization here, it has hitherto been necessary and customary to specify the respective type of candle for the annealing control device and / or the motor control, so that the glow plugs could be correspondingly activated in dependence on this specification.
Eine dynamische Unterscheidung zwischen verschiedenen Kerzentypen während des Betriebes der Glühkerzen war bisher nicht möglich, was den Nachteil hatte, dass bei fehlender oder nicht korrekter Vorgabe des Kerzentyps, beispielsweise bei einem Kerzentypwechsel die Ansteuerung der Glühkerzen nicht in angemessener Weise erfolgen konnte.A dynamic distinction between different types of candles during operation of the glow plugs was previously not possible, which had the disadvantage that in the absence or incorrect specification of the candle type, for example in a Kerzentypwechsel the control of the glow plugs could not be made in an appropriate manner.
Weiterhin war es bisher nicht möglich, den an einer Brennkraftmaschine verbauten Typ der Glühkerzen zu analysieren und zu diagnostizieren, um beispielsweise dann, wenn nach einem Glühkerzenwechsel ein Typ von Glühkerzen erkannt wird, der nicht zu dem Typ der Brennkraftmaschine passt, oder wenn Glühkerzentypen verschiedener Art an der Brennkraftmaschine verbaut sind und ein Mischbetrieb ausgeschlossen werden soll, eine entsprechende Warnanzeige abzugeben.Furthermore, it has hitherto not been possible to analyze and diagnose the type of glow plugs installed on an internal combustion engine, for example, when a type of glow plugs that does not match the type of internal combustion engine is detected after a glow plug change, or if glow plug types of various types are installed on the internal combustion engine and a mixed operation is to be excluded to make a warning message.
Die der Erfindung zugrunde liegende Aufgabe besteht demgegenüber darin, ein Verfahren und eine Vorrichtung der eingangs genannten Art anzugeben, die so ausgestaltet sind, dass der Betrieb der Glühkerzen jederzeit in der zu dem jeweiligen Glühkerzentyp passenden Form erfolgen kann.The object underlying the invention is in contrast to provide a method and an apparatus of the type mentioned above, which are designed so that the operation of the glow plugs can be done at any time in the appropriate form of the respective Glühkerzentyp.
Diese Aufgabe wird gemäß der Erfindung durch ein Verfahren nach dem Patentanspruch 1 und eine Vorrichtung nach dem Patentanspruch 20 gelöst.This object is achieved according to the invention by a method according to
Bei dem erfindungsgemäßen Verfahren und der erfindungsgemäßen Vorrichtung wird der Typ der Glühkerzen, der an der Brennkraftmaschine verbaut ist, erkannt und wird die Information hierüber zur Grundlage der Ansteuerung der Glühkerzen gemacht.In the method according to the invention and the device according to the invention, the type of glow plugs installed on the internal combustion engine is recognized, and the information about them is used as the basis for controlling the glow plugs.
Besonders bevorzugte Ausgestaltungen und Weiterbildung des erfindungsgemäßen Verfahrens und der erfindungsgemäßen Vorrichtung sind Gegenstand der Patentansprüche 2 bis 19 bzw. Gegenstand der Patentansprüche 21 bis 28.Particularly preferred embodiments and development of the method and apparatus of the invention are subject matter of
Gemäß der Erfindung wird somit durch die Analyse eines glühkerzentypischen Parameters, beispielsweise des elektrischen Widerstandes der Glühkerzen und insbesondere des Widerstandsgradienten im Glühbetrieb und/oder des Widerstandes im kalten Zustand und/oder des Widerstandes im heißen Zustand oder der Kapazität, Induktivität oder Resonanzfrequenz in einer Vorphase der verwandte Glühkerzentyp erkannt und wird der jeweils erkannte Typ über ein Signal an das Glühsteuergerät und/oder Motorsteuergerät gemeldet. Sind entsprechende Applikationsparameter in der Motorsteuerung hinterlegt, so wird der entsprechende Parametersatz für den erkannten Glühkerzentyp geladen und wird die Ansteuerung der Glühkerzen dementsprechend angepasst.According to the invention is thus by the analysis of a Glühkerzentypischen parameter, for example, the electrical resistance of the glow plugs and in particular the resistance gradient in the annealing operation and / or the resistance in the cold state and / or the resistance in the hot state or the capacitance, inductance or resonance frequency in a preliminary phase the related Glühkerzentyp recognized and reported each type is reported via a signal to the annealing control unit and / or engine control unit. If corresponding application parameters are stored in the engine control system, the corresponding parameter set for the recognized glow plug type is loaded and the control of the glow plugs is adapted accordingly.
In dieser Weise kann beispielsweise bei Niedervoltglühkerzen eine Überbestromung einzelner Niedervoltglühkerzen verhindert werden. Ein fehlerhafter Tausch einzelner Glühkerzen, beispielsweise in einer Werkstatt kann gleichfalls erkannt werden, wenn das Fahrzeug mittels eines Diagnosetesters entsprechend überprüft wird. Diese Funktionen können bereits mit schonendem getakteten Aufheizen vor dem eigentlichen Start der Brennkraftmaschine erzielt werden.In this way, for example, in Niedervoltglühkerzen over-energizing individual low-voltage glow plugs are prevented. A faulty exchange of individual glow plugs, for example in a workshop can also be detected if the vehicle is checked by means of a diagnostic tester. These functions can already be achieved with gentle clocked heating before the actual start of the internal combustion engine.
Im Folgenden wird anhand der zugehörigen Zeichnungen ein besonders bevorzugtes Ausführungsbeispiel der Erfindung näher beschrieben. Es zeigen
- Fig. 1 in einer grafischen Darstellung die Entwicklung des Glühkerzenwiderstandes zweier Glühkerzentypen, z.B. einer Stahlglühkerze und einer Keramikglühkerze bei einer Betriebsspannung von 12 V gegenüber der Zeit jeweils und
- Fig. 2 ein Blockschaltbild einer Glühanordnung mit Erkennung des Glühkerzentyps.
- Fig. 1 is a graphic representation of the development of the glow plug resistance of two glow plug types, such as a steel glow plug and a ceramic glow plug at an operating voltage of 12 V versus time respectively and
- Fig. 2 is a block diagram of an annealing arrangement with detection of Glühkerzentyps.
Wie es in Fig. 1 dargestellt ist, unterscheiden sich verschiedene Glühkerzentypen Typ 1 und Typ 2, beispielsweise Keramikglühkerzen von Stahlglühkerzen, dadurch, dass der Widerstand im kalten Zustand, der Widerstand im heißen Zustand und der Widerstandsgradient während des Glühbetriebs deutlich verschieden sind. Das gilt auch für den Verlauf des Widerstandes bei einem Glühbetrieb mit getakteter Aufheizung der Glühkerzen.As shown in FIG. 1,
Über diese Unterschiede wird gemäß der Erfindung erreicht, dass im Betrieb der Brennkraftmaschine jederzeit der Typ der jeweils vorgesehenen Glühkerzen erkannt wird.About these differences is achieved according to the invention that the type of each provided glow plugs is detected at any time during operation of the internal combustion engine.
Fig. 2 zeigt in einem Blockschaltbild eine entsprechende Glühanordnung gemäß der Erfindung.Fig. 2 shows in a block diagram a corresponding annealing arrangement according to the invention.
Ein Rechner 1 weist einen Rechenkern 4 mit Programmablauf, eine Aufnahme 3 für Spannungs- und Stromwert sowie eine Steuerung 2 einer Leistungselektronik 5 auf. Die Leistungselektronik 5 ist über Signalleitungen mit der Werteaufnahme 3 des Rechners 1 verbunden, wobei über die Signalleitung 8 die Spannung an der Glühkerze anliegt und über die Leitung 9 ein Signal anliegt, das dem Strom entspricht, der durch die Leistungselektronik 5 zur daran angeschlossenen Glühkerze 6 fließt. Die Glühkerze 6 hat eine Masseanbindung 7.A
Die Arbeitsweise gemäß der Erfindung ist die Folgende:The operation according to the invention is the following:
Während des Betriebes der Glühkerze, z.B. in der Vorglühphase, in der die Maschine noch nicht gestartet ist, bzw. im Betrieb der Brennkraftmaschine wird der glühkerzentypische Parameter, nämlich der Widerstand der Glühkerzen erfasst und ausgewertet. Hierzu sind im Speicher der Glüh- oder Motorsteuerung entsprechende Parameter für die verschiedenen Glühkerzentypen hinterlegt, so dass über einen entsprechenden Vergleich der Typ der Glühkerze bestimmt und erkannt werden kann.During operation of the glow plug, for example in the pre-glow phase, in which the engine has not yet started, or during operation of the internal combustion engine, the glow plug typical parameter, namely the resistance of the glow plugs is detected and evaluated. For this purpose, corresponding parameters for the different types of glow plugs are stored in the memory of the glow or motor control, so that the type of glow plug can be determined and recognized by means of a corresponding comparison.
Es wird beispielsweise zunächst der Kaltwiderstand bestimmt, um eine Vorentscheidung darüber zu treffen, ob es sich beim Glühkerzentyp um eine Stahl- oder Keramikglühkerze handelt. Danach kann mit einem schnellen Aufheizen der Glühkerzen begonnen werden und der Widerstandsgradient während des schnellen Aufheizens ermittelt und zur endgültigen Festlegung des Glühkerzentyps verwandt werden.For example, the cold resistance is first determined in order to make a preliminary decision as to whether the glow plug type is a steel or ceramic glow plug. Thereafter, a quick heating of the glow plugs can be started and the resistance gradient during the rapid heating can be determined and used for the final determination of the glow plug type.
Diese Vorgehensweise hat den Vorteil, dass das schnelle Aufheizen verkürzt oder verlängert werden kann.This procedure has the advantage that the rapid heating up can be shortened or extended.
Es ist aber auch möglich, ausschließlich den Kaltwiderstand oder den Widerstandsgradienten beim Aufheizen zum Identifizieren des Glühkerzentyps heranzuziehen. Es kann auch das Verhalten des Widerstandes während eines getakteten Aufheizens zur Unterscheidung herangezogen werden.But it is also possible to use only the cold resistance or the resistance gradient during heating to identify the glow plug type. It can also be used to distinguish the behavior of the resistor during a clocked heating.
Gemäß der Erfindung kann die Erkennung des Glühkerzentyps auch vor der Inbetriebnahme des gesamten die Glühkerze umfassenden Glühsystem insbesondere zu einem vordefinierten Zeitpunkt in einer Vorphase zur Glühkerzentyperkennung erfolgen. Als Parameter kann dabei statt eines Widerstandswertes die Kapazität, die Induktivität oder die Resonanzfrequenz eines Schwingkreises herangezogen werden, der aus der Kapazität und der Induktivität der Glühkerze besteht.According to the invention, the recognition of the Glühkerzentyps can also be done before the start of the entire glow plug comprehensive glow system in particular at a predefined time in a preliminary phase for Glühkerzentyperkennung. Instead of a resistance value, the capacitance, the inductance or the resonant frequency of a resonant circuit, which consists of the capacitance and the inductance of the glow plug, can be used as a parameter.
Es hat sich gezeigt, dass auch über diese Parameter eine sichere Typerkennung möglich ist. Das trifft insbesondere dann zu, wenn die Kaltwiderstände von Glühkerzen in Keramik- und Metallausführungen großen Streuungen unterliegen, die dann über die kapazitiven und induktiven Eigenschaften die verschiedenen Glühkerzentypen sehr deutlich voneinander unterschieden werden können. Versuche haben gezeigt, dass insbesondere die Induktivität ein sicheres Erkennungsmerkmal ist. So ergibt sich bei einer Stahlkerze mit einer Glühwendel eine Induktivität, die um den Faktor 3 bis 4 größer als bei einer entsprechenden Keramikglühkerze ist.It has been shown that a secure type recognition is also possible via these parameters. This is particularly true when the cold resistances of glow plugs in ceramic and metal designs are subject to large variations, which can then be distinguished very clearly from each other on the capacitive and inductive properties of the various glow plug types. Experiments have shown that in particular the inductance is a sure distinguishing feature. Thus, in the case of a steel candle with an incandescent filament, an inductance which is greater by a factor of 3 to 4 than with a corresponding ceramic glow plug results.
Durch eine einfache Messung der elektrischen Eigenschaften, insbesondere der Induktivität, kann somit eine sichere Erkennung des Glühkerzentyps gewährleistet werden. Die Messung erfolgt dabei in der Vorphase vor der Beheizung der Glühkerze vorzugsweise zu einem definierten Zeitpunkt, so dass bereits beim ersten Aufheizvorgang der Glühkerze das typspezifische Aufheizprogramm genutzt werden kann.By a simple measurement of the electrical properties, in particular the inductance, a reliable detection of the Glühkerzentyps can thus be ensured. The measurement is carried out in the pre-phase before the heating of the glow plug preferably at a defined time, so that even during the first heating of the glow plug, the type-specific heating program can be used.
Nachdem der Glühkerzentyp erkannt ist, wird somit ein entsprechender Parametersatz für den erkannten Glühkerzentyp, der in der Glühsteuerung oder der Motorsteuerung gespeichert ist, herangezogen und geladen und erfolgt die Steuerung der Glühkerzen mit den herangezogenen Parametersatz, der zu dem erkannten Glühkerzentyp gehört.Thus, once the glow plug type is detected, a corresponding set of parameters for the detected glow plug type stored in the glow control or motor control is used and loaded, and the glow plugs are controlled with the parameter set used that belongs to the identified glow plug type.
Die Erkennung des Glühkerzentyps kann einzeln für jede Glühkerze, d.h. jeden Glühkerzenstrang getrennt erfolgen, so dass die einzelnen Glühkerzen je nach erkanntem Typ separat angesteuert werden können. Auch ein Mischbetrieb aus einer gemeinsamen Erkennung und Ansteuerung einer Gruppe von Glühkerzen sowie einzelner Glühkerzen ist möglich.The detection of the glow plug type can be done individually for each glow plug, i. each glow plug strand separately, so that the individual glow plugs can be controlled separately depending on the detected type. A mixed operation of a common detection and control of a group of glow plugs and individual glow plugs is possible.
Gemäß der Erfindung erfolgt somit eine Unterscheidung des Glühkerzentyps, wird der erkannte Glühkerzentyp der Steuerung gemeldet und wird ein dementsprechender passender Parametersatz automatisch ausgewählt, falls entsprechende Applikationsdaten des Glühkerzentyps in der Steuerung hinterlegt sind.According to the invention thus distinguishes the Glühkerzentyps, the detected Glühkerzentyp the controller is reported and a corresponding matching parameter set is automatically selected if appropriate application data of Glühkerzentyps are stored in the controller.
Neben der Variante, bei der die Applikationsdaten in der Glühsteuerung, d.h., im Glühsteuergerät gespeichert sind, gibt es auch die Variante, bei der diese Daten in der Motorsteuerung, d.h., im Motorsteuergerät gespeichert sind. Wenn unterschiedliche Kerzentypen erkannt werden sollen, die in einer Brennkraftmaschine verbaut sein können, können entsprechende Applikationsdaten in beiden Steuergeräten gespeichert sein. In diesem Fall ist das relevante Steuergerät mal das Glühsteuergerät und mal das Motorsteuergerät.In addition to the variant in which the application data in the annealing control, ie, stored in the annealing control unit, there is also the variant in which these data are stored in the engine control, ie, in the engine control unit. If different types of candles to be detected, which may be installed in an internal combustion engine, corresponding application data may be stored in both control units. In this case, the relevant control unit is sometimes the glow control unit and sometimes the engine control unit.
Das hat den Vorteil, dass die Zerstörung von Glühkerzen durch eine Ansteuerung mit Parametern des falschen Kerzentyps vermieden wird, dass eine ungültige Kombination von Kerzentyp und Motortyp erkannt werden kann, und dass bei einem Kerzenwechsel der Typ der jeweils neu eingesetzten Glühkerzen nicht der Steuerung mitgeteilt, d.h., dem Glühsteuergerät bzw. der Motorsteuerung vorgegeben werden muss, was die Fehleranfälligkeit herabsetzt.This has the advantage that the destruction of glow plugs by driving with parameters of the wrong type of candle is avoided, that an invalid combination of candle type and engine type can be detected, and that in a candle change the type of each newly inserted glow plugs not communicated to the controller, ie, the annealing control unit or the motor control must be specified, which reduces the susceptibility to errors.
