Description
Die Erfindung betrifft ein Verfahren zur Steuerung einer von einem Stellelement erzeugten Stellbewegung eines Bauteiles, insbesondere der Ausrückbewegung einer Kupplung, bei welchem mittels eines Rechners aufgrund von Sollwerten eines Sollwertgebers und Positionsdaten eines Wegsensors für die Position des Bauteils Ansteuerbefehle erzeugt werden. Weiterhin betrifft die Erfindung eine mittels eines Stellelementes nach dem Verfahren gemäß zumindest einem der vorangehenden Ansprüche motorisch betätigbare Kupplung, welche zur Ansteuerung des Stellelementes einen Rechner aufweist, der eingangsseitig mit einem Wegsensor einer Kupplungsbetätigung und einem Sollwertgeber eines Kupplungspedals Verbindung hat.The The invention relates to a method for controlling one of an actuator generated adjusting movement of a component, in particular the disengagement movement a clutch in which by means of a computer due to Setpoints of a setpoint generator and position data of a position sensor of the component control commands are generated. Furthermore the invention by means of an actuating element according to the method according to at least one of the preceding claims motor actuated Coupling, which for controlling the actuator a computer having the input side with a displacement sensor of a clutch actuator and has a setpoint generator of a clutch pedal connection.
In heutigen Kraftfahrzeugen werden häufig motorisch betätigbare Kupplungen eingesetzt, die nach dem vorgenannten Verfahren gesteuert werden. Der Wegsensor ist dabei erforderlich, um zu erreichen, dass die Kupplung trotz systembedingter Toleranzen und trotz eines unterschiedlichen Verschleißzustandes ihres Kupplungsbelages stets den vom Kupplungspedal festgelegten Stellhub ausführt. Der Wegsensor ermöglicht es dem Rechner, so lange Ansteuerbefehle zu erzeugen, bis ein ge forderter Sollwert erreicht wird. Erst wenn die Regelabweichung Null wird, dann wird die Zufuhr von Fremdenergie zu dem Stellelement unterbrochen. Ähnliche Systeme für motorisch zu verstellende Bauteile kommen in der Technik und auch in Kraftfahrzeugen häufig vor, beispielsweise motorische Drosselklappensteller oder motorische Türschließvorrichtungen.In Today's motor vehicles are often operated by motor Couplings used, which controlled by the aforementioned method become. The displacement sensor is required to achieve that the clutch despite system-related tolerances and despite a different wear state their clutch lining always set by the clutch pedal Stellhub executes. Of the Displacement sensor allows It the computer, so long to generate control commands until a ge requested setpoint is reached. Only when the control deviation is zero, then the supply of external energy to the actuator interrupted. Similar systems for motor To be adjusted components are used in the art and in motor vehicles often before, for example, motorized throttle actuator or motor Door closing devices.

Nachteilig bei den bisher bekannten Verfahren zur Steuerung von Stellbewegungen ist das Verhalten solcher Systeme bei Ausfall des Wegsensors, durch den die Rückmeldung der ausgeführten Stellbewegung erfolgt. Meist geht mit dem Ausfall des Wegsensors die Steuer- und Regelbarkeit des Systems verloren. Dabei kommt es oftmals zu einer vollen Energiebeaufschlagung des Stellelementes, was beispielsweise bei Kupplungen zu einer Beschädigung der Membranfeder und des Ausrücksystems führen kann.adversely in the previously known methods for controlling positioning movements is the behavior of such systems in case of failure of the displacement sensor, through the feedback the executed Actuating movement takes place. Mostly with the failure of the displacement sensor lost the controllability of the system. It happens often to a full energization of the actuator, which, for example, in couplings to damage the diaphragm spring and of the release system can lead.
Zur

von fremdkraftbetätigten
Einrichtungen durch Dauerdruckbeaufschlagung infolge Ausfalls ihres

sei auf die
Der Erfindung liegt das Problem zugrunde, ein Verfahren der eingangs genannten Art so auszubilden, dass bei Ausfall des Wegsensors des zu betätigenden Bauteils eine Notbetätigung möglich wird, ohne dass hierzu ein hohen Kräften standhaltender Anschlag erforderlich ist. Wei terhin soll eine nach diesem Verfahren gesteuerte Kupplung geschaffen werden.Of the Invention is based on the problem, a method of the initially so-called type in such a way that in case of failure of the displacement sensor of the to be operated Component an emergency operation possible is, without this a high forces resistant stop is required. Wei terhin should be controlled by this method Coupling to be created.
Das erstgenannte Problem wird erfindungsgemäß dadurch gelöst, dass in einem nicht flüchtigen Speicher in Abhängigkeit von den Signalen des Sollwertgebers die vom Rechner aufgrund der Rückmeldungen durch den Wegsensor abgegebenen Ansteuerbefehle für das zu verstellende Bauteils abgespeichert werden und dass für den Fall des Ausfalls des Wegsensors das Bauteil aufgrund dieser Speicherdaten gesteuert wird.The The first problem is inventively achieved in that in a non-volatile memory dependent on from the signals of the setpoint generator from the computer due to the feedback triggered by the displacement sensor control commands for the verstellende component be stored and that in the case the failure of the displacement sensor, the component due to this memory data is controlled.
Dieses verfahren baut auf der Erkenntnis auf, dass sich die für die Steuerung solcher Bauteile zu berücksichtigenden Parameter der Steuerkette im Regelfall nicht plötzlich verändern. Wenn man deshalb bei Ausfall des Wegsensors das Bauteil so steuert wie zuvor, als der Wegsensor noch funktionstüchtig war, dann ergeben sich aufgrund der Stellbefehle Stellbewegungen, welche zunächst nicht wesentlich von denen abweichen, die sich unter Berücksichtigung der Rückmeldungen des Wegsensors ergaben. Deshalb ist mit dem erfindungsgemäßen Verfahren eine sehr gute Notbetätigung möglich, welche sich erst nach längerer Nutzung gegenüber der exakten Betätigung aufgrund von Rückmeldungen bezüglich der Stellbewegungen verschlechtert.This procedure builds on the knowledge that is responsible for the control such components to be considered As a rule, do not change the parameters of the timing chain suddenly. So if you join Failure of the displacement sensor controls the component as before, as the Distance sensor still functional was, then arise due to the control commands Stellbewegungen, which first do not differ materially from those that are taking into account the feedback of the displacement sensor. Therefore, with the inventive method a very good emergency operation possible, which only after a longer time Use opposite the exact operation due to feedback regarding the Stellbewegungen deteriorated.
Auch bei einem Ausfall des Sollwertgebers ist eine Notbetätigung noch möglich, wenn gemäß einer Weiterbildung des Verfahrens mittels eines bei maximalem Hub des Steuerteils betätigten Kontaktschalters das zu verstellende Bauteil aufgrund der zuvor abgespeicherten Daten in seine Endstellung bewegt wird.Also in case of failure of the setpoint generator an emergency operation is still possible, if according to one Development of the method by means of a maximum stroke of the Operated control parts Contact switch the component to be adjusted due to the previously stored data is moved to its end position.
Das zweitgenannte Problem, nämlich die Schaffung einer Vorrichtung zur Steuerung einer motorisch betätigbaren Kupplung gemäß dem vorgenannten Verfahren, wird erfindungsgemäß dadurch gelöst, dass der Rechner einen nicht flüchtigen Speicher zum Abspeichern der Ansteuerbefehle für die Kupplungsbetätigung in Abhängigkeit von den Sollwerten des Sollwertgebers aufweist.The second-mentioned problem, namely the provision of a device for controlling a motor-actuated clutch according to the aforementioned method is inventively achieved in that the computer is a non-volatile memory for storing the drive commands for the clutch actuation function of the target having values of the setpoint generator.
Eine solche Kupplung ermöglicht auch bei Ausfall ihres Wegsensors eine Notbetätigung und schließt aus, dass es bei einem solchen Ausfall zu ei ner Dauerdruckbeaufschlagung der Kupplungsbetätigung und dadurch zu einem Überdrücken ihrer Kupplungsfeder kommen kann.A allows such coupling an emergency operation even if its position sensor fails and excludes that it is in such a failure to ei ner Dauerdruckbeaufschlagung the clutch operation and thereby overpressing their Clutch spring can come.
Die erfindungsgemäße Kupplung erlaubt selbst bei einem Ausfall ihres Sollwertgebers eine Notbetätigung, wenn gemäß einer Weiterbildung der Erfindung der Rechner zum Ansteuern der Kupplungsbetätigung nach den in seinem Speicher abgespeicherten Signalen aufgrund eines Signals des Kontaktschalters ausgebildet ist.The coupling according to the invention allows an emergency operation even if its setpoint generator fails if according to one Development of the invention of the computer for driving the clutch actuator after the stored in its memory signals due to a signal the contact switch is formed.
Die Erfindung lässt verschiedene Ausführungsmöglichkeiten zu. Zur weiteren Verdeutlichung ihres Grundprinzips ist in der Zeichnung eine Kupplung mit ihrem Ausrücksystem und einer Kupplungsbetätigung dargestellt und wird nachfolgend beschrieben.The Invention leaves various execution options to. To further clarify its basic principle is in the drawing a clutch with its release system and a clutch operation and will be described below.
