Die Erfindung betrifft eine Motorstaubremsvorrichtung, mit einer brennkraftmaschinen-internen Motorstaubremseinrichtung und einer Motorbremsklappe in einer Abgasleitung, mit einem Stellmotor für die Motorbremsklappe und zugeordnetem Leistungsteil, das seine Befehle von einer Steuereinheit erhält, und mit einem den Druck in der Abgasleitung strömungsmäßig vor der Motorbremsklappe erfassenden Drucksensor.The invention relates to an engine dust brake device with an internal combustion engine Engine dust brake device and an engine brake flap in an exhaust pipe, with a servomotor for the engine brake flap and assigned power section, which receives its commands from a control unit, and with one the pressure pressure sensor in the exhaust line in terms of flow in front of the engine brake flap.

Die Erfindung geht aus von der DE 33 39 053 C2. Dort ist eine Motorbremsklappe mittels eines druckluftbetriebenen Stellmotors verstellbar. Ein Drucksensor, der den Abgasdruck in der Abgasleitung strömungsmäßig vor der Motorbremsklappe erfaßt, ist mit einem Magnetventil verbunden, das bei Erreichen einer bestimmten Druckschwelle umschaltet und so ein druckluftgesteuertes Öffnen der Motorbremsklappe bewirkt. Eine Regelung im Sinne variabler Durchlaßquerschnitte, angepaßt an den jeweiligen Motorbremsleistungsbedarf erlaubt diese bekannte Lösung jedoch nicht.The invention is based on DE 33 39 053 C2. There is an engine brake flap adjustable by means of a pneumatic actuator. A pressure sensor that the Exhaust gas pressure in the exhaust line is measured in terms of flow in front of the engine brake flap, is connected to a solenoid valve that when a certain pressure threshold is reached switches and thus a compressed air-controlled opening of the engine brake flap causes. A regulation in the sense of variable passage cross sections, adapted to the However, this known solution does not allow the respective engine braking power requirement.

Es ist daher Aufgabe der Erfindung, eine Motorstaubremseinrichtung der gattungsgemäßen Art dahingehend zu verbessern, daß eine feinfühlige Regelung der Durchlaßquerschnitte der Motorbremsklappe abhängig vom tatsächlichen Motorbremsleistungsbedarf möglich und außerdem die Motorstaubremsvorrichtung kostengünstig herstellbar und montierbar ist.It is therefore an object of the invention to provide an engine dust brake device of the generic type Art to improve in such a way that a sensitive control of the passage cross-sections the engine brake flap depending on the actual engine brake power requirement possible and also the engine dust brake device inexpensive can be produced and assembled.

Diese Aufgabe ist gemäß dem Kennzeichen des Anspruchs 1 dadurch gelöst, daß die Meßsignale des Drucksensors und/oder eines Temperatursensors, gegebenenfalls auch Drehzahlsignale der Brennkraftmaschine, über die Steuereinheit einer elektronischen Reglereinheit zugeführt werden, die den Betrieb der Steuereinheit und der Brennkraftmaschine anhand eingespeicherter Kennfelder und Betriebsdaten regelt, und daß ein Bremsvorrichtungsmodul vorgesehen ist, der als Basiselement einen Abgasleitungsrohrabschnitt aufweist, der mit endseitigen Flanschen in einen entsprechenden Freiraum der Abgasleitung eingebaut ist, in welchem Abgasleitungsrohrabschnitt die Motorbremsklappe eingebaut und mit ihrer Achse schwenkbar gelagert ist, und an welchem Abgasleitungsrohrabschnitt außen der Stellmotor für die Motorbremsklappe, das zugehörige Leistungsteil, die zugehörige Steuereinheit sowie der Drucksensor und/oder Temperatursensor angebaut sind.This object is achieved according to the characterizing part of claim 1 in that the measurement signals of the pressure sensor and / or a temperature sensor, if appropriate also speed signals of the internal combustion engine, via the control unit Electronic controller unit are supplied, the operation of the control unit and controls the internal combustion engine based on stored maps and operating data, and that a braking device module is provided, which as a base element Exhaust pipe section that has end flanges in a corresponding clearance of the exhaust pipe is installed, in which exhaust pipe section the engine brake flap installed and pivoted with its axis and on which exhaust pipe section outside the servomotor for the Engine brake flap, the associated power unit, the associated control unit and the pressure sensor and / or temperature sensor are attached.

Aufgrund dessen, daß die Meßsignale des Drucksensors und/oder Temperatursensors, gegebenenfalls auch Drehzahlsignale der Brennkraftmaschine, über die Steuereinheit der elektronischen Reglereinheit zugeführt werden, ist es möglich, anhand von eingespeicherten Kennfeldern und Betriebsdaten mit einer sehr hohen Regelungsgüte die Ein- bzw Verstellung der Motorbremsklappe zu bewerkstelligen. Zum anderen ergibt sich aufgrund der Zusammenfassung der Motorbremsklappe, deren Stellmotor und Leistungsteil sowie dem Drucksensor und/oder Temperatursensor zu einem Bremsvorrichtungsmodul mit als Trägerbasis fungierendem Abgasleitungsrohrabschnitt, eine bisher für solche Teile noch nie erreichte Kompaktheit mit der Möglichkeit einer günstigen, brennkraftmaschinennahen Anordnung.Due to the fact that the measurement signals of the pressure sensor and / or temperature sensor, optionally also speed signals of the internal combustion engine, via the control unit supplied to the electronic controller unit, it is possible to use of stored maps and operating data with a very high control quality to adjust or adjust the engine brake flap. To the others result from the summary of the engine brake flap, the Servomotor and power section as well as the pressure sensor and / or temperature sensor a brake device module with an exhaust pipe section that functions as a carrier base, a compactness with the Possibility of a favorable arrangement close to the internal combustion engine.

Dem Stellmotor 4 ist ein Leistungsteil 7 zugeordnet, das im dargestellten Beispiel aus einem elektromagnetischen Absperr-/Durchlaßventil 7' und einem elektrischen Schaltorgan 7'' für Betätigung des letzteren besteht. Dieses Leistungsteil 7 erhält seine Befehle von einer Steuereinheit 8. Mit 9 ist ein Drucksensor bezeichnet, der den Abgasdruck strömungsmäßig vor der Motorbremsklappe 2 erfaßt. Anstelle des Drucksensors 9 oder auch zusätzlich zü diesem kann ein Temperatursensor 10 vorgesehen sein, der die Temperatur der Abgase strömungsmäßig vor der Motorbremsklappe 2 erfaßt. Diese Druckmeßsignale und/oder Temperaturmeßsignale, gegebenenfalls auch Drehzahlsignale nM der Brennkraftmaschine, werden über Signalleitungen 9', 10', 11 der Steuereinheit 8 und von dieser über entsprechende Datenübertragungsleitungen 12 einer elektronischen Reglereinheit 13 zugeführt. Diese besteht beispielsweise aus einer Ein- und Ausgabeperipherie, einem Mikroprozessor, Daten- und Programmspeichern, weiche Baugruppen über ein Datenbussystem miteinander verknüpft sind. In die Datenspeicher sind Kennfelder und Betriebsdaten für die Betriebssteuerung der Brennkraftmaschine sowohl im Zugbetrieb als auch Bremsbetrieb abgelegt. Die Reglereinheit 13 regelt somit per im Programmspeicher abgespeichertem Programm anhand der Kennfelder und Betriebsdaten sowohl den Betrieb der Brennkraftmaschine als auch den Betrieb der Steuereinheit 8.

Instead of the pressure sensor 9 or additionally to this, a temperature sensor 10 can be provided which detects the temperature of the exhaust gases in terms of flow in front of the engine brake flap 2. These pressure measurement signals and / or temperature measurement signals, possibly also speed signals n M of the internal combustion engine, are supplied to the control unit 8 via signal lines 9 ', 10', 11 and from the latter to an electronic controller unit 13 via corresponding data transmission lines 12. This consists, for example, of an input and output periphery, a microprocessor, data and program memories, which assemblies are linked together via a data bus system. Characteristic maps and operating data for the operational control of the internal combustion engine are stored in the data memory both in the traction mode and in the braking mode.
