Das Verfahren weist folgende Verfahrensschritte auf:
- – Ermittlung der der Brennkraftmaschine zugeführten Frischluftmasse;
- – Regelung der der Brennkraftmaschine zuzuführenden Gasmasse auf einen vorbestimmten Gasmassen-Sollwert durch Ansteuerung der Abgasrückführeinrichtung in Abhängigkeit von der ermittelten Frischluftmasse; und
- – Regelung des Ladedrucks auf einen vorbestimmten Ladedruck-Sollwert durch Ansteuerung der Abgasturboladereinrichtung in Abhängigkeit von der die Turbine beaufschlagenden Abgasmasse bzw. dem die Turbine beaufschlagenden Abgasdruck derart, dass die zugeführte Frischluftmasse sich auf einen vorbestimmten Soll-Frischluftmassenwert einstellt. Die Regelung des Ladedrucks wird auf diese Weise mit der Frischluftmassenregelung gekoppelt, da der Ladedruck in Abhängigkeit vom Abgasgegendruck geregelt wird.
- - Determining the internal combustion engine supplied fresh air mass;
- - Regulation of the internal combustion engine to be supplied gas mass to a predetermined gas mass target value by controlling the exhaust gas recirculation device in dependence on the determined fresh air mass; and
- - Regulation of the boost pressure to a predetermined boost pressure target value by controlling the exhaust gas turbocharger in response to the turbine acting exhaust gas mass or the turbine acting exhaust gas pressure such that the supplied fresh air mass adjusts to a predetermined target fresh air mass. The control of the boost pressure is coupled in this way with the fresh air mass control, since the boost pressure is regulated in dependence on the exhaust backpressure.

Problematisch ist bei allen Regelungen, dass der Regelkreis des Luftmassenstroms mit dem Ladedruckregelkreis stark verkoppelt ist. Änderungen des Abgasgegendruckes beeinflussen sowohl die rückgeführte Abgasmenge, als auch den Ladedruck. Die einzelnen Regelstrecken beeinflussen sich gegenseitig und weisen zudem unterschiedliche Totzeiten auf. Die physikalischen Kopplungen der Regelstrecken müssen bei einer zu entwerfenden Regelung beachtet werden, da diese zu ungewollten Rückkopplungen, zu Schwingverhalten und Instabilität des Regelvorganges führen können.The problem with all regulations is that the control circuit of the air mass flow is strongly coupled with the boost pressure control loop. Changes in the exhaust back pressure affect both the recirculated exhaust gas amount, as well as the boost pressure. The individual controlled systems influence each other and also have different dead times on. The physical couplings of the controlled systems must be taken into account in a scheme to be designed, as these can lead to unwanted feedback, vibration behavior and instability of the control process.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung zur Luftmassen- oder Abgasmassenstromregelung bereitzustellen, welche eine weitgehend entkoppelte Regelung des Luftmassen- oder Abgasmassenstromes vom Ladedruck erlaubt, bei der Rückwirkungen des Ladedruckregelkreises insbesondere bei dynamischen Regelvorgängen die Massenstromregelung nur gering beeinflussen.Of the Invention is based on the object, a method and an apparatus to provide air mass or exhaust mass flow control, which a largely decoupled control of the air mass or exhaust gas mass flow allowed by the boost pressure, at the repercussions the boost pressure control loop in particular in dynamic control operations the Only slightly influence mass flow control.

Vorteile der ErfindungAdvantages of the invention
Erfindungsgemäß vorteilhaft wird von einer Luftmassenstromregelung aus der Regelabweichung von einem Ist- zu einem Sollwert des Luftmassenstromes ein Sollwertsignal für einen zugehörigen Abgasgegendruck erzeugt. Der Abgasgegendruck wird hierbei mit einem gemessenen oder modellierten Abgasgegendruck verglichen und die Regelabweichung wird von einem Abgasgegendruckregler ausgeglichen. Der Abgasgegendruck wird über die Stellgröße der rückgeführten Abgasmenge geregelt und für die Realisierung wird ein AGR-Ventil hinsichtlich seiner Öffnungsgeometrie angepasst. Die Luftmassenstromregelung erfolgt dabei parallel zur Ladedruckregelung, wobei die Ladedruckregelung auf Basis der Ladedruck-Regelabweichung erfolgt. Die erfindungsgemäße Regelung des Luftmassenstroms erfolgt mit einer Kaskadenregelung, die eine äußere und eine innere Schleife umfasst, wobei die äußere Schleife den Luftmassenstrom regelt. Der Luftmassenstromreglerausgang bildet den Sollwert für den Abgasgegendruck.According to the invention advantageous is from an air mass flow control of the control deviation of an actual to a desired value of the air mass flow a setpoint signal for one associated Exhaust back pressure generated. The exhaust gas back pressure is here with a measured or modeled exhaust back pressure compared and the Control deviation is compensated by an exhaust backpressure regulator. The exhaust back pressure is over the manipulated variable of the recirculated exhaust gas quantity regulated and for the realization becomes an EGR valve with regard to its opening geometry customized. The air mass flow control is carried out parallel to Boost pressure control, whereby the boost pressure control based on the boost pressure control deviation he follows. The regulation according to the invention the mass air flow takes place with a cascade control, an external and an inner loop, the outer loop comprising the air mass flow regulates. The air mass flow controller output forms the setpoint for the exhaust gas back pressure.
Der Abgasgegendruck wird mit dem Regler der inneren Schleife geregelt. Am Ausgang des Abgasgegendruckreglers liegt das Ansteuersignal für ein Abgasrückführventil an.Of the Exhaust back pressure is controlled by the inner loop regulator. At the output of the exhaust back pressure regulator is the drive signal for an exhaust gas recirculation valve at.
Alternativ kann die Luftmassenstromregelung als Regelung des Abgasmassenstromes ausgeführt sein. Abgasmassenstrom und Luftmassenstrom sind über den Gesamtmassenstrom des Motors gekoppelt.alternative can the air mass flow control as regulation of the exhaust gas mass flow accomplished be. Exhaust gas mass flow and air mass flow are above the total mass flow of Motors coupled.
Die Kaskadenregelung des Luftmassen- oder Abgasmassenstroms hat einen entkoppelnden Effekt auf den Luftmassen- oder Abgasmassenstromregelkreis gegenüber einem Ladedruckregelkreis. Das Druckgefälle über dem Abgasrückführventil und somit der Abgasgegendruck ist maßgebend für den Abgasrückführmassenstrom. Das Druckgefälle wird mit Hilfe des AGR-Ventils eingestellt.The Cascade control of the air mass or exhaust gas mass flow has one decoupling effect on the air mass or exhaust gas mass flow loop across from a boost pressure control loop. The pressure gradient across the EGR valve and thus the exhaust back pressure is decisive for the exhaust gas recirculation mass flow. The pressure gradient is adjusted by means of the EGR valve.
Der Abgasgegendrucksollwert wird vom Regler der äußeren Schleife entsprechend dem Luftmassenstromsollwert erzeugt und vom Regler der inneren Schleife eingeregelt. Die Regelung des Abgasgegendruckes in der inneren Regelschleife ermöglicht eine weitgehende Entkopplung gegenüber der Rückwirkung aus der Ladedruckregelung. Die Ladedruckänderungen durch Öffnen und Schließen eines Waste Gates oder durch einen Stelleingriff auf die Leitschaufeln des Turboladers verändert den Abgasgegendruck. Diese Änderung wird unmittelbar vom Abgasgegendruckregler ausgeglichen. Die als Störgröße für die Luftmassenstromregelung wirkende Änderung des Istwertes des Abgasgegendrucks aufgrund der veränderten Laderaktuator-Stellung wird durch die innere Regelschleife ausgeregelt, bevor sie die gesamte Regelstrecke des Luftmassenstromes durchläuft.Of the Exhaust backpressure setpoint is determined by the outer loop regulator the air mass flow setpoint and the inner loop controller adjusted. The regulation of the exhaust backpressure in the inner control loop allows a substantial decoupling compared to the reaction from the boost pressure control. The boost pressure changes by opening and closing a waste gate or by a control action on the vanes the turbocharger changed the exhaust back pressure. This change is compensated directly by the exhaust back pressure regulator. As Disturbance variable for the air mass flow control acting change the actual value of the exhaust back pressure due to the changed Charger actuator position is adjusted by the inner control loop, before it passes through the entire controlled system of the air mass flow.
Die Ansprechzeit der Abgasgegendruckregelung ist im Vergleich zur Luftmassen- oder Abgasmassenstromregelung kürzer. Die unterschiedlichen Lauf-Totzeiten der Regelstrecken werden mit der Kaskadierung genutzt.The The response time of the exhaust back pressure control is compared to the air mass or exhaust gas mass flow control shorter. The different running dead times of the controlled systems are included the cascading used.
