Ein derartiges Verfahren ist aus der DE-OS 42 35 794 bekannt. Dabei ist gemäß diesem Dokument ein Regler vorgesehen, der ganz allgemein über eine Drossel und ein Absperrventil die Abgasrückführrate in Abhängigkeit von Betriebsparametern der Brennkraftmaschine regelt. Nähere Angaben zu den Betriebsparametern sind nicht gege- ben.Such a method is known from DE-OS 42 35 794. According to this document, a controller is provided which generally regulates the exhaust gas recirculation rate as a function of operating parameters of the internal combustion engine via a throttle and a shut-off valve. No further details on the operating parameters are given.
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zur Steuerung der Abgasrückführung bei einer Brennkraftmaschine bereitzustellen, das/die die verschiedensten Einsatz- bedingungen einer Brennkraftmaschine berücksichtigen kann. Diese Aufgabe wird dadurch gelöst, daß die Steuereinrichtung ein Grundkennfeld über den Parametern „Brennkraftmaschinen-Drehzahl" und „je Arbeitsspiel zugeführte Kraftstoffmenge" aufweist und daß die Grundsignale des Grundkennfeldes durch Korrektursignale ab- gebende, bedarfsmäßig zuschaltbare Korrektureinrichtungen beeinflußbar sind. In dem Grundkennfeld sind über den zuvor genannten Parametern Kennlinien abgelegt, die die Grundsignale festlegen. Schon mit diesen Grundsignalen kann zumindest bei bestimmten Einsätzen der Brennkraftmaschine die Abgasrückführung gesteuert wer- den, wobei auch vorgesehen ist, daß beispielsweise bei einem Störfall durch beispielsweise defekte Sensoren für eine oder mehrere Korrektureinrichtungen ein "Notprogramm" nach den Grundsignalen gefahren wird. In den meisten Anwendungsfällen der Brennkraftmaschine wird gemäß der vorliegenden Erfindung das Grundkennfeld durch Korrektursignale abgebende Korrektureinrichtungen bedarfsmäßig beeinflußt. So ist es vorteilhaft vorgesehen, in dem Grundkennfeld die Abgasrückführwerte allgemein für verschiedene Brennkraftmaschinen abzulegen, wobei dann diese Grundsignale je nach Bauart und Ausführung der Brennkraftmaschine (Zylinderzahl, einge- stellte Leistung usw.) und den nachfolgend beschriebenen sonstigen Korrektureinrichtungen beeinflußbar sind. Durch diese Ausbildung kann immer die gleiche Vorrichtung verwendet werden und die Teilevielfalt gering gehalten werden.The invention is based on the object of providing a method and a device for controlling the exhaust gas recirculation in an internal combustion engine which can take into account the most diverse operating conditions of an internal combustion engine. This object is achieved in that the control device has a basic map over the parameters “internal combustion engine speed” and “fuel quantity supplied per work cycle” and in that the basic signals of the basic map can be influenced by correction devices that provide correction signals that can be activated as required. In the basic map, characteristic curves are stored above the parameters mentioned above, which define the basic signals. Even with these basic signals, the exhaust gas recirculation can be controlled at least for certain uses of the internal combustion engine, it also being provided that, for example in the event of a malfunction, for example defective sensors for one or more correction devices, an "emergency program" is run according to the basic signals. In most applications of the internal combustion engine, the basic map is influenced as required by correction devices emitting correction signals. For example, it is advantageously provided that the exhaust gas recirculation values are generally stored for various internal combustion engines in the basic characteristic map, these basic signals then being able to be influenced depending on the type and design of the internal combustion engine (number of cylinders, set power, etc.) and the other correction devices described below. With this design, the same device can always be used and the number of parts can be kept low.
In Weiterbildung ist zunächst eine Verwendungs-Korrektureinrichtung vorgesehen, die ein Verwendungs-Korrektursignal abgibt, das dem Grundsignal multiplikativ aufgeschaltet wird. Diese Verwendungs- Korrektureinrichtung berücksichtigt also ganz allgemein den vorgegebenen Verwendungszweck der Brennkraftmaschine und legt hierfür Korrektursignale fest, mit denen die Grundsignale überlagert werden. Mögliche Verwendungszwecke sind beispielsweise der Einsatz der Brennkraftmaschine in einem Fahrzeug, einer landwirtschaftlichen Maschine einem Baufahrzeug oder einem Gerät.In a further development, a use correction device is initially provided which emits a use correction signal which is applied multiplicatively to the basic signal. This usage correction device therefore generally takes into account the specified intended use of the internal combustion engine and, for this purpose, specifies correction signals with which the basic signals are superimposed. Possible uses are, for example, the use of the internal combustion engine in a vehicle, an agricultural machine, a construction vehicle or a device.
In Weiterbildung der Erfindung ist eine Brennkraftmaschinen-Abnahme-Korrektureinrichtung vorgesehen, die ebenfalls entsprechende Korrektursignale abgibt. In diese Korrektureinrichtung werden folglich bei dem Abnahmelauf der Brennkraftmaschine nach deren Herstellung und Montage grundlegende Korrekturwerte eingespeichert, die ganz speziell auf den jeweiligen Abnahmelauf der Brennkraftmaschine zugeschnitten sind. Darunter sind auch grundlegende Werte zu dem Typ und der Ausführung der Brennkraftmaschine zu verstehen.In a further development of the invention, an internal combustion engine acceptance correction device is provided, which likewise emits corresponding correction signals. As a result, basic correction values are stored in this correction device during the acceptance run of the internal combustion engine after its manufacture and assembly, which are tailored very specifically to the respective acceptance run of the internal combustion engine. This includes basic values for the type and design of the internal combustion engine.
Weiterhin ist eine Fahrzeugdaten-Korrektureinrichtung vorgesehen. In dieser können dann relevante Fahrzeugdaten, wie beispielsweise Fahrzeugdaten und Einsatzgebiet, abgespeichert werden. In diesem Zusammenhang ist weiterhin eine Fahrzeugbeschleunigungs-Korrek- tureinrichtung vorgesehen, die in weiterer Ausgestaltung die Para- meter: Einspritzpumpenreglervorgabe, Gaspedalstellung und Rauchgrenze berücksichtigt. Hierbei werden dann in jeweils einem Kompe- rator die aktuelle Gaspedalstellung mit der Einspritzpumpenreglervorgabe und die Rauchgrenze mit der Einspritzpumpenreglervorgabe verglichen. Wenn bei dem Vergleich in beiden Komperatoren festge- stellt wird, daß vorgebbare Einstellungen überschritten werden, wird das Ausgangssignal jeweils als Störgröße erfaßt, wobei die beiden Ausgangsstörgrößen in einem Und-Glied zusammengefaßt werden. D. h., nur wenn bei beiden Komperatoren eine Störgröße vorliegt, wird hinter dem Und-Glied ein weiterer Schalter betätigt. Gleichzeitig werden die Einspritzpumpenreglervorgabe und die Rauchgrenze in einem Divisor zusammengeführt und entsprechend dem sich ergebenden Wert wird aus einer nachfolgenden Bewertungskurve ein Wert für das Maß der Schließung der Abgasrückführung entnommen. Dieser Wert wird dann multiplikativ auf das Grundsignal aufgeschaltet, wenn dem zuvor erläuterten Schalter das Vorliegen einer Störgröße signalisiert wird.A vehicle data correction device is also provided. Relevant vehicle data, such as vehicle data and area of application, can then be stored in this. In this context, a vehicle acceleration correction device is also provided, which in a further embodiment takes into account the parameters: injection pump controller specification, accelerator pedal position and smoke limit. The current accelerator pedal position is then compared in a comparator with the injection pump regulator specification and the smoke limit with the injection pump regulator specification. If it is found in the comparison in both comparators that predeterminable settings are exceeded, the output signal is in each case recorded as a disturbance variable, the two output disturbance variables being combined in an AND element. In other words, only if there is a disturbance variable in both comparators is a further switch operated behind the AND gate. At the same time, the injection pump regulator specification and the smoke limit are combined in a divisor and, according to the resulting value, a value is derived from a subsequent evaluation curve Value for the degree of closure of the exhaust gas recirculation taken. This value is then applied multiplicatively to the basic signal when the presence of a disturbance variable is signaled to the previously explained switch.
Weiterhin ist eine Umgebungsdruck-Korrektureinrichtung vorgesehen, die insbesondere bei Einsatz der Brennkraftmaschine bzw. des Fahrzeugs im Gebirge zum Einsatz kommt.Furthermore, an ambient pressure correction device is provided, which is used in particular when the internal combustion engine or the vehicle is used in the mountains.
In Weiterbildung der Erfindung ist eine Kühlmitteltemperatur- Korrektureinrichtung vorgesehen, die die Kühlmitteltemperatur der Brennkraftmaschine bei der Steuerung der Abgasrückführung berücksichtigt.In a development of the invention, a coolant temperature correction device is provided which takes the coolant temperature of the internal combustion engine into account when controlling the exhaust gas recirculation.
Darüber hinaus ist eine Dynamik-Korrektureinrichtung vorgesehen, die die Fahrweise des Fahrers eines Fahrzeuges berücksichtigt. In dieses Dynamik-Korrektursignal gehen die Drehzahl der Brennkraftmaschine und die zugeführte Kraftstoffmenge je Arbeitsspiel ein, wobei aus beiden ermittelt wird, ob ein stationärer Fahrzustand vorliegt oder eine extreme Fahrweise (Gaspedalwechsel andauernd zwischen Nullstellung und Vollaststellung). Wenn bei dieser Einrichtung das Vorliegen eines dynamischen Betriebs ermittelt wird, wird im Unterschied zu den bisherigen Signalen bei dieser Einrichtung ein Korrekturwert auf das Grundsignal aufaddiert.In addition, a dynamic correction device is provided which takes into account the driving style of the driver of a vehicle. The speed of the internal combustion engine and the amount of fuel supplied per work cycle are included in this dynamic correction signal, it being determined from both whether there is a steady-state driving state or an extreme driving style (accelerator pedal change constantly between zero position and full load position). If the presence of dynamic operation is determined in this device, in contrast to the previous signals in this device, a correction value is added to the basic signal.
Allen diesen Korrektureinrichtungen ist eine Einrichtung nachgeschaltet, die überprüft, ob die Motorbremse des Fahrzeuges eingeschaltet ist. Sofern dies der Fall ist, wird die Abgasrückführung automatisch auf null reduziert bzw. ganz ausgeschaltet. Ebenfalls wird während des Startvorgangs die Abgasrückführung abgeschaltet. Weitere vorteilhafte Ausgestaltungen der Erfindung sind der Zeichnungsbeschreibung zu entnehmen, in der ein Ausführungsbeispiel der Erfindung näher beschrieben ist.All these correction devices are followed by a device that checks whether the engine brake of the vehicle is switched on. If this is the case, the exhaust gas recirculation is automatically reduced to zero or switched off completely. The exhaust gas recirculation is also switched off during the starting process. Further advantageous embodiments of the invention can be found in the drawing description, in which an embodiment of the invention is described in more detail.
In dem Grundkennfeld 1 sind verschiedene Kennlinien abgespeichert, von denen jeder einzelne Punkt der Kennlinie eine bestimmte Abgasrückführrate festlegt. Dabei wird dieser jeweilige Punkt bestimmt durch die Eingangsgrößen „Drehzahl der Brennkraftmaschine ne" und „der Brennkraftmaschine je Arbeitsspiel zugeführte Kraftstoffmenge mf". Dabei ist im vorliegenden Fall die zugeführte Kraftstoffmenge mf je Arbeitsspiel definiert als zugeführte Kraftstoffmenge je Hub eines der Einspritzpumpenelemente der Brennkraftmaschine. Das Aus- gangs-Grundsignal aus diesem Grundkennfeld 1 bestimmt in Abhängigkeit von den genannten Eingangsgrößen die Abgasrückführmenge. Dieses Grundsignal kann durch die nachfolgend erläuterten Korrektureinrichtungen, die entsprechende Korrektursignale abgeben, beeinflußt werden und somit die tatsächliche Abgasrückführrate an gegebene Betriebsbedingungen der Brennkraftmaschine angepaßt werden.Various characteristic curves are stored in the basic characteristic diagram 1, of which each individual point of the characteristic curve defines a specific exhaust gas recirculation rate. This particular point is determined by the input variables “speed of the internal combustion engine n e ” and “fuel quantity m f supplied to the internal combustion engine per work cycle”. In the present case, the quantity of fuel supplied m f per work cycle is defined as the quantity of fuel supplied per stroke of one of the injection pump elements of the internal combustion engine. The basic output signal from this basic characteristic diagram 1 determines the exhaust gas recirculation quantity as a function of the input variables mentioned. This basic signal can be influenced by the correction devices explained below, which emit corresponding correction signals, and thus the actual exhaust gas recirculation rate can be adapted to the given operating conditions of the internal combustion engine.
Hierbei erfolgt zunächst eine Anpassung durch drei Korrektureinrichtungen, die grundlegende Parameter beim Betrieb der Brennkraftmaschine berücksichtigen und die dem Grundsignal multiplikativ aufgeschaltet werden. Dies ist zunächst eine Brennkraftmaschinen-Ver- wendungs-Korrektureinrichtung 2, die entsprechend der Leistungsgruppe und/oder dem Verwendungszweck der Brennkraftmaschine, beispielsweise in einem Nutzfahrzeug, in einer landwirtschaftlichen Maschine, in einem Baufahrzeug oder einem Gerät, ein entsprechendes Brennkraftmaschinen-Verwendungs-Korrektursignal abgibt. Die- ses entsprechende Signal kann in einer zentralen Elektronik-Steuereinrichtung, in der das gesamte System integriert sein kann, ge- speichert werden. Gleiches gilt für eine Brennkraftmaschinen-Abnahme-Korrektureinrichtung 3, die ein entsprechendes Korrektursignal, das bei dem Abnahmelauf der Brennkraftmaschine erstellt wird, abgibt. In diesem Korrektursignal können u. a. insbesondere brennkraftmaschinenspezifische Daten, wie Anzahl der Zylinder, Art der Einspritzvorrichtung usw., Einfluß finden. Weiterhin erfolgt hiermit ein Toleranzausgleich des Abgasrückführsystems. Das entsprechende Korrektursignal wird ebenfalls multiplikativ dem Ausgangssignal des Grundkennfeldes aufgeschaltet. Schließlich ist eine Fahrzeugdaten-Korrektureinrichtung 4 vorgesehen, die ein fahrzeugspezifisches Korrektursignal abgibt. In dieser Korrektureinrichtung können relevante fahrzeugspezifische Daten, wie beispielsweise zu dem speziellen Ansaug- und Abgassystem, aber gegebenenfalls auch Fahrzeuggewicht, Getriebeübersetzungen und Einsatzgebiet (beispielsweise Baustellen-, Nah- oder Fern-Ver- kehr), Einfluß finden.In this case, an adjustment is first made by three correction devices, which take into account basic parameters during the operation of the internal combustion engine and which are applied multiplicatively to the basic signal. This is firstly an internal combustion engine use correction device 2, which emits a corresponding internal combustion engine use correction signal in accordance with the power group and / or the intended use of the internal combustion engine, for example in a commercial vehicle, in an agricultural machine, in a construction vehicle or in a device . This corresponding signal can be stored in a central electronic control device in which the entire system can be integrated. be saved. The same applies to an internal combustion engine acceptance correction device 3, which emits a corresponding correction signal that is generated during the acceptance run of the internal combustion engine. In this correction signal, in particular data specific to internal combustion engines, such as the number of cylinders, type of injection device, etc., can be influenced. Furthermore, tolerance compensation of the exhaust gas recirculation system is hereby carried out. The corresponding correction signal is also applied multiplicatively to the output signal of the basic map. Finally, a vehicle data correction device 4 is provided, which emits a vehicle-specific correction signal. Relevant vehicle-specific data, such as, for example, on the special intake and exhaust system, but possibly also vehicle weight, transmission ratios and area of use (for example construction site, local or long-distance traffic) can be influenced in this correction device.
Weiterhin ist eine Umgebungsdruck-Korrektureinrichtung 5 vorgesehen, in der eine vom gemessenen Umgebungsdruck pa abhängige Korrekturkurve abgespeichert ist. Hiermit wird insbesondere der mit zunehmender Höhe abfallende Umgebungsdruck pa, der einen direkten Einfluß auf die Füllung der Brennkraftmaschine und damit die Verbrennung hat, berücksichtigt.An ambient pressure correction device 5 is also provided, in which a correction curve dependent on the measured ambient pressure p a is stored. This takes into account, in particular, the ambient pressure p a falling with increasing height, which has a direct influence on the filling of the internal combustion engine and thus on the combustion.
Darüberhinaus ist eine Fahrzeug-Beschleunigungs-Korrektureinrich- tung 6 vorgesehen, die verschiedene nachfolgend erläuterte Eingangssignale verarbeitet und letztendlich ein entsprechendes Korrektursignal, das eine Beschleunigungsbewertung darstellt, abgibt. Eingangs der Fahrzeug-Beschleunigungs-Korrektureinrichtung sind zwei Komperatoren 7a, 7b vorgesehen, wobei in den Komperator 7a ein Messwert ms für die Gaspedalstellung eingeht, der mit einem Einspritzpumpenreglervorgabewert md, der ein Drehmomentlimit darstellt, verglichen wird und bei Überschreiten ein Ausgangssignal abgibt. In dem Komperator 7b geht direkt der Einspritzpumpenregler- vorgabewert md ein, wobei dieser Wert hier mit einem Reglervorga- bewert mr, der einem Rauchgrenzwert entspricht, verglichen wird und bei Überschreiten eines Grenzwertes ein Ausgangssignal auch aus dem Komperator 7b abgegeben wird. Die Ausgangssignale der beiden Komperatoren 7a, 7b werden in einem Und-Glied 8 zusammengeführt, wobei das Und-Glied beim Vorliegen einer Störgröße - ent- sprechend einem Ausgangssignal - aus beiden Komperatoren 7a und 7b ein Schaltsignal abgibt. Dieses Schaltsignal wird einem Stell-Glied 9 zugeführt, wobei das Stell-Glied 9 bei Vorliegen eines Ausgangssignals aus dem Und-Glied 8 den Ausgang des Stell-Glieds 9 mit einem Eingang 0, dessen Eingangssignal nachfolgend beschrieben wird, verbindet. Für den Fall, daß keiner oder nur einer der Komperatoren 7a, 7b ein Störsignal abgibt und entsprechend das Und-Glied 8 keine Störgröße meldet, ist der Eingang des Stell-Gliedes 9 auf den Eingang 1 geschaltet, so daß kein Fahrzeug-Beschleunigungs- Korrektursignal abgegeben wird. Für den Fall, daß ein Korrektursignal abgegeben wird, ermittelt sich dieses aus dem Einspritzpumpenreg- lervorgabewert md und dem Reglervorgabewert mr die beide durch einen Divisor 18 miteinander verbunden werden und in eine Bewertungseinrichtung 10 eingehen. Diese Bewertungseinrichtung 10 weist eine Kennlinie auf, die in Abhängigkeit des eingehenden Signals den Umfang des Schließens der Abgasrückführung festlegt. Das Ausgangssignal der Bewertungseinrichtung 10 wird - wie zuvor ausgeführt - als Fahrzeugbeschleunigungs-Korrektursignal über das Stell- Glied 9 multiplikativ auf die Ausgangssignale des Grundkennfeldes 1 aufgeschaltet. Weiterhin ist eine Brennkraftmaschinen-Kühlmittel-Temperatur- Korrektureinrichtung 1 1 vorgesehen, in die die aktuelle Kühlmitteltemperatur tw eingeht und aus einer Korrekturkurve ein Korrektursignal bestimmt und abgibt. Hierbei kann dann auch ggf. auch noch festgestellt werden, ob sich die Brennkraftmaschine in der Phase des Warmlaufens nach einem Kaltstart befindet.In addition, a vehicle acceleration correction device 6 is provided, which processes various input signals explained below and ultimately emits a corresponding correction signal, which represents an acceleration evaluation. Two comparators 7a, 7b are provided at the input of the vehicle acceleration correction device, with a measured value m s for the accelerator pedal position being received in the comparator 7a Injection pump regulator default value m d , which represents a torque limit, is compared and outputs an output signal when exceeded. The injection pump controller default value m d is directly received in the comparator 7b, this value being compared here with a controller default value m r which corresponds to a smoke limit value and an output signal is also output from the comparator 7b if a limit value is exceeded. The output signals of the two comparators 7a, 7b are combined in an AND element 8, the AND element emitting a switching signal from both comparators 7a and 7b when an interference variable is present, corresponding to an output signal. This switching signal is fed to an actuating element 9, the actuating element 9 connecting the output of the actuating element 9 to an input 0, the input signal of which is described below, when an output signal from the AND element 8 is present. In the event that none or only one of the comparators 7a, 7b emits an interference signal and, accordingly, the AND element 8 does not report an interference variable, the input of the actuator 9 is connected to the input 1, so that no vehicle acceleration correction signal is delivered. In the event that a correction signal is emitted, this is determined from the injection pump regulator preset value m d and the regulator preset value m r, both of which are connected to one another by a divisor 18 and are received in an evaluation device 10. This evaluation device 10 has a characteristic curve which determines the extent of the closing of the exhaust gas recirculation as a function of the incoming signal. The output signal of the evaluation device 10 is - as explained above - applied as a vehicle acceleration correction signal to the output signals of the basic map 1 by means of the actuator 9. Furthermore, an internal combustion engine coolant temperature correction device 11 is provided, into which the current coolant temperature t w is entered and which determines and emits a correction signal from a correction curve. In this case, it can also be determined whether the internal combustion engine is in the warm-up phase after a cold start.
Schließlich ist eine Dynamik-Korrektureinrichtung 12 vorgesehen, die ebenfalls ein Korrektursignal abgibt, das aber dem Grundsignal im Unterschied zu den bisherigen Signalen additiv aufgeschaltet wird. Dieser Korrekturwert wird aus der Drehzahl ne der Brennkraftmaschine und der zugeführten Kraftstoff masse mf je Arbeitsspiel ermittelt, wobei die Drehzahl ne der Brennkraftmaschine einer drehzahlabhängigen Korrekturkennlinie 13 und die zugeführte Kraftstoffmasse mf einem gedämpften Differenzierglied 14 zugeführt wird. Das Ausgangssignal des gedämpften Differenziergliedes 14 wird in einen Minimum/Maximum-Begrenzer 15 weitergeleitet, wobei als Ausgangswerte Werte zwischen 0 und 1 abgegeben werden. Dabei stellt der Wert 0 einen stationären Fahrzustand und der Wert 1 einen extremen Fahrzustand dar. Der Wert 0 läßt sich mit einer ruhigen Fahrweise mit einer konstanten Gaspedal-Stellung vergleichen, während der Wert 1 sich mit einer sehr unruhigen Fahrweise mit einem dauernd bewegten Fahrpedal vergleichen läßt. Alle Werte zwischen 0 und 1 sind zulässig und werden verarbeitet.Finally, a dynamic correction device 12 is provided, which likewise emits a correction signal, but which, in contrast to the previous signals, is added to the basic signal. This correction value is determined from the speed n e of the internal combustion engine and the supplied fuel mass m f per work cycle, the speed n e of the internal combustion engine being fed to a speed-dependent correction characteristic curve 13 and the supplied fuel mass m f to a damped differentiator 14. The output signal of the damped differentiating element 14 is forwarded to a minimum / maximum limiter 15, values between 0 and 1 being output as output values. The value 0 represents a stationary driving state and the value 1 an extreme driving state. The value 0 can be compared with a quiet driving style with a constant accelerator pedal position, while the value 1 can be compared with a very restless driving style with a constantly moving accelerator pedal leaves. All values between 0 and 1 are permitted and are processed.
Letztendlich ist noch eine Vorrichtung 16 vorgesehen, die berücksichtigt, ob die Motorbremse ein- oder ausgeschaltet ist oder ob ein Startvorgang vorliegt. Ist die Motorbremse eingeschaltet oder liegt ein Motorstart vor, wird der Umschalter 17 auf den Eingang 0 geschaltet, so daß während dieser Betriebszustände die Abgasrückführung ebenfalls außer Betrieb ist. Finally, a device 16 is also provided which takes into account whether the engine brake is switched on or off or whether there is a starting process. If the engine brake is switched on or there is an engine start, the changeover switch 17 is switched to input 0, so that the exhaust gas recirculation is also out of operation during these operating states.
