Description
Die Erfindung betrifft ein Verfahren zur Steuerung eines hybridischen Antriebsstrangs mit einer Brennkraftmaschine mit einer Kurbelwelle und einer in einer Riemenscheibenebene der Brennkraftmaschine angeordneten und mittels eines schaltbaren Planetengetriebes mit der Kurbelwelle in Wirkeingriff stehenden Elektromaschine, wobei das Planetengetriebe während eines Startvorgangs der Brennkraftmaschine von einem eine zwischen einem Hohlrad des Planetengetriebes und einem drehfest angeordneten Gehäuse angeordnete Bremse betätigenden Aktor über einen Aktorweg auf eine vorgegebene Schließposition gesteuert wird.The invention relates to a method for controlling a hybrid powertrain with an internal combustion engine with a crankshaft and arranged in a pulley plane of the internal combustion engine and by means of a switchable planetary gear with the crankshaft in operative engagement electric machine, wherein the planetary gear during a starting operation of the internal combustion engine of a between a Ring gear of the planetary gear and a rotatably arranged housing arranged brake actuating actuator is controlled via a Aktorweg to a predetermined closed position.

Aufgabe der Erfindung ist daher, ein Verfahren vorzuschlagen, bei dem ein gattungsgemäßer hybridischer Antriebsstrang dauerhaft und ohne Verschleiß der Reibbeläge der Bremse und ohne Überbelastung des Aktors betrieben werden kann. The object of the invention is therefore to propose a method in which a generic hybrid powertrain can be operated permanently and without wear of the friction linings of the brake and without overloading the actuator.
Die Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst. Die diesem untergeordneten Ansprüche geben vorteilhafte Ausführungsformen wieder.The object is solved by the features of
Das vorgeschlagene Verfahren dient der Steuerung eines hybridischen Antriebsstrangs mit einer Brennkraftmaschine mit einer Kurbelwelle und einer in einer Riemenscheibenebene der Brennkraftmaschine angeordneten und mittels eines schaltbaren Planetengetriebes mit der Kurbelwelle in Wirkeingriff stehenden Elektromaschine. Hierbei wird das Planetengetriebe während eines Startvorgangs der Brennkraftmaschine von einem eine zwischen einem Hohlrad des Planetengetriebes und einem drehfest angeordneten Gehäuse angeordnete Bremse betätigenden Aktor über einen Aktorweg reibschlüssig geschaltet. In vorgeschlagener Weise wird der Startvorgang bei bevorzugt geschlossener Bremse durchgeführt. Eine Schließposition der Bremse wird durch Verfahren eines Aktors beziehungsweise einer Aktormechanik entlang eines Aktorwegs eingestellt. Um eine Überlastung des Aktors, der Aktormechanik und der Bremse zu vermeiden, wird die Schließposition mit einem mittels einer aus einer elektrischen Steuergröße des Aktors und einer Verfahrgeschwindigkeit des Aktors ermittelten Gradientenänderung bestimmten Tastpunkt zwischen Hohlrad und Gehäuse verglichen und abhängig von diesem eingestellt. Die Gradientenänderung wird dabei an einem Knickpunkt entlang des Aktorwegs ermittelt, an dem sich eine Lüftwegskraft, die durch einen inneren Widerstand wie Reibung des Aktors und der Aktormechanik sowie der durch diese betätigten Bauteile der Bremse bedingt ist, und die Anpresskraft, die bei Ausbildung eines Reibeingriffs der Bremse infolge der Verspannung der bewegten Bauteile der Bremse gegen das Gehäuse ausgebildet wird, schneiden. Der durch die Lüftwegs- und Anpresskraft gebildete Knickpunkt kann dabei dem Tastpunkt zugeordnet werden. Die Ermittlung kann durch den Schnittpunkt der Tangenten von Lüftwegskraft und Anpresskraft entlang des Axialwegs erfolgen.The proposed method is used to control a hybrid powertrain with an internal combustion engine having a crankshaft and an arranged in a pulley plane of the internal combustion engine and by means of a switchable planetary gear with the crankshaft in operative engagement electric machine. In this case, the planetary gear during a starting operation of the internal combustion engine is frictionally engaged by a one between a ring gear of the planetary gear and a rotatably arranged housing arranged brake actuating actuator via an actuator. In a proposed manner, the starting process is performed at preferably closed brake. A closed position of the brake is set by moving an actuator or an actuator mechanism along an actuator path. In order to avoid an overload of the actuator, the actuator mechanism and the brake, the closing position is compared with a determined by means of a determined from an electrical control variable of the actuator and a travel speed of the actuator gradient between the ring gear and housing and adjusted depending on this. The gradient change is determined at a break point along the Aktorwegs at which a Lüftwegskraft, which is due to an internal resistance such as friction of the actuator and the actuator mechanism and actuated by these components of the brake, and the contact pressure, the formation of a frictional engagement the brake is formed due to the tension of the moving components of the brake against the housing, cut. The break point formed by the Lüftwegs- and contact force can be assigned to the touch point. The determination can be made by the intersection of the tangents of Lüftwegskraft and contact force along the Axialwegs.
Gemäß einer vorteilhaften Ausführungsform des Verfahrens kann der Tastpunkt bei konstanter Verfahrgeschwindigkeit des Aktors und einer Gradientenänderung der elektrischen Steuergröße, beispielsweise einer elektrischen Spannung oder einem elektrischen Strom ermittelt werden. Hierbei kann der Elektromotor des Aktors in an sich üblicher Weise gesteuert werden, um einen Axialweg bis zur Schließposition zurückzulegen, beispielsweise mittels einer Pulsweitenmodulation. Hierbei wird auf eine konstante Verfahrgeschwindigkeit geregelt und die Änderung der elektrischen Steuergröße erfasst. Aus dieser Steuergröße wird die Gradientenänderung am Übergang von der Lüftwegskraft in die Anpresskraft bestimmt und als Tastpunkt festgelegt. Aufgrund der steilen Kennlinie der Anpresskraft über den Aktorweg kann anhand der bestimmten Gradientenänderung ein Knickpunkt in schneller und einfacher Weise ermittelt und als Tastpunkt festgelegt werden. According to an advantageous embodiment of the method, the touch point can be determined at a constant travel speed of the actuator and a gradient change of the electrical control variable, for example, an electrical voltage or an electric current. Here, the electric motor of the actuator can be controlled in a conventional manner to cover an axial path to the closed position, for example by means of a pulse width modulation. This is controlled to a constant travel speed and detects the change in the electrical control variable. From this control variable, the gradient change at the transition from the Lüftwegskraft is determined in the contact pressure and set as the touch point. Due to the steep characteristic curve of the contact force over the Aktorweg can be determined based on the specific gradient change a break point in a quick and easy way and set as the touch point.
In einer alternativen Ausführungsform des Verfahrens kann der Tastpunkt bei konstanter elektrischer Größe und einer Gradientenänderung der Verfahrgeschwindigkeit ermittelt werden. Hierbei wird die elektrische Größe, beispielsweise Strom, Spannung oder Pulsweiten einer Spannung konstant vorgegeben. Aufgrund der unterschiedlichen Last über den Lüftwegbereich und den Betätigungsbereich der Bremse stellen sich über den Weg unterschiedliche Verfahrgeschwindigkeiten ein, die an einem Knickpunkt zwischen Lüftweg und Betätigungsweg der Bremse zu einer Gradientenänderung der Verfahrgeschwindigkeit führen. Der Knickpunkt wird dabei dem Tastpunkt zugeordnet. In an alternative embodiment of the method, the touch point can be determined with a constant electrical variable and a gradient change of the travel speed. Here, the electrical variable, for example, current, voltage or pulse widths of a voltage is set constant. Due to the different load on the Lüftwegbereich and the operating range of the brake set on the way different traversing speeds that lead to a change in gradient of the traversing speed at a break point between Lüftweg and actuation of the brake. The break point is assigned to the touch point.
In vorteilhafter Weise kann bei bekannter mechanischer Steifigkeit zwischen Aktor und Bremse abhängig von dem ermittelten Tastpunkt die Schließposition auf eine maximale Anpresskraft begrenzt werden. Durch die Beziehung der Steifigkeit über den Aktorweg kann beispielsweise anhand einer Kraftkennlinie unabhängig von Änderungen eines Reibwerts der Bremse und Verschleißvorgängen ausgehend vom Tastpunkt eine über den Aktorweg auftretende Anpresskraft ermittelt werden und die Schließposition zur Vermeidung von Überbeanspruchung auf eine maximale Anpresskraft begrenzt werden. Hierbei kann die Schließposition innerhalb der maximalen Anpresskraft auf einen vorgegebenen Schlupf zwischen Hohlrad und Gehäuse eingestellt werden. Hierbei kann der Aktor schlupfgeregelt gesteuert werden. Alternativ kann der Aktor weggesteuert betätigt werden, wobei der entsprechend gesteuerte Aktorweg in Schließposition auf einen gleichen oder kleineren maximalen Aktorweg bei maximaler Anpresskraft gesteuert wird. Hierbei kann der zur Ansteuerung der Schließposition zu steuernde Aktorweg eine vorgegebene, adaptierbare Wegdifferenz zwischen dem Tastpunkt und dem der Schließposition entsprechenden Wegpunkt sein. Advantageously, with known mechanical stiffness between actuator and brake depending on the determined touch point, the closed position can be limited to a maximum contact force. Due to the relationship of the stiffness over the Aktorweg can be determined, for example, based on a force characteristic independent of changes in a coefficient of friction of the brake and wear processes starting from the touch point occurring over the Aktorweg contact force and the closed position to avoid overstressing to a maximum contact force. Here, the closing position can be set within the maximum contact pressure to a predetermined slip between the ring gear and the housing. In this case, the actuator can be controlled slip controlled. Alternatively, the actuator can be actuated remotely controlled, wherein the appropriately controlled Aktorweg is controlled in the closed position to a same or smaller maximum Aktorweg at maximum contact force. In this case, the actuator travel to be controlled for activating the closed position can be a predetermined, adaptable path difference between the touch point and the waypoint corresponding to the closed position.
Weiterhin kann zur Vermeidung eines Einlaufens des Aktors und dessen Aktormechanik an einer über längere Zeit konstanten Schließposition vorgesehen sein, bei vorgegebenem Schlupf unterhalb der Schließposition bei maximaler Anpresskraft zu vorgegebenen, beispielsweise regelmäßig vorgesehenen Zeitpunkten die Schließposition an die Schließposition bei maximaler Anpresskraft einzustellen.Furthermore, in order to avoid an entry of the actuator and its actuator mechanism can be provided at a constant closing position over a longer period, set the closing position to the closed position at maximum contact pressure at a predetermined slip below the closed position at maximum contact force at predetermined, for example regularly scheduled times.
In vorteilhafter Weise kann anhand des Tastpunkts, einer Bremskennlinie der Anpresskraft über den Aktorweg und einem Startmoment der Brennkraftmaschine ein Reibwert eines zwischen Hohlrad und Gehäuse angeordneten Bremsbelags ermittelt werden. Aus diesem Reibwert kann wiederum der zu erwartende Schlupf bei vorgegebenem Aktorweg ermittelt werden, so dass eine Schließposition mit entsprechend ermitteltem Schlupf gezielt und daher schneller angefahren werden kann. Dies kann zu beschleunigten Startzeiten der Brennkraftmaschine führen. Das Startmoment kann anhand des Kennfelds der Brennkraftmaschine, deren Auslegungsparameter, Außen- und/oder Kühlwassertemperatur und/oder dergleichen ermittelt oder modelliert werden. Advantageously, a coefficient of friction of a brake lining arranged between the ring gear and the housing can be determined on the basis of the touch point, a braking characteristic of the contact force via the actuator travel and a starting torque of the internal combustion engine. From this coefficient of friction, in turn, the expected slip can be determined for a given actuator travel, so that a closed position with appropriately determined slip can be approached specifically and therefore more quickly. This can lead to accelerated start times of the internal combustion engine. The starting torque can be determined or modeled based on the map of the internal combustion engine, their design parameters, outdoor and / or cooling water temperature and / or the like.
Des Weiteren kann zur Aktivierung des Reibbelags der Bremse eine auf vorgegebenen Schlupf zwischen Hohlrad und Gehäuse mittels eines vorgegebenen Aktorwegs eingestellte Schließposition zur Erhöhung einer in den Bremsbelag eingetragenen Reibenergie zumindest kurzzeitig mit größerem Schlupf bei vermindertem Aktorweg betrieben werden. Durch den erhöhten Energieeintrag in den Reibbelag kann dabei ein oberflächlich verhärteter Reibbelag wieder aktiviert und damit mit einem höheren Reibwert versehen werden. Hierdurch werden insgesamt das Bremsverhalten der Bremse verbessert und die Anpresskraft vermindert.Furthermore, in order to activate the friction lining of the brake, a closing position set to predetermined slip between the ring gear and the housing by means of a predetermined actuator travel can be operated at least for a short time with greater slip with reduced actuator travel to increase a friction energy introduced into the brake lining. Due to the increased energy input into the friction lining a surface hardened friction lining can be reactivated and thus provided with a higher coefficient of friction. As a result, the overall braking performance of the brake can be improved and the contact pressure reduced.
