Abstract
Description
Die Erfindung bezieht sich auf ein Getriebe; insbesondere ein Getriebe mit erster und zweiter Kupplung.The The invention relates to a transmission; in particular a transmission with first and second clutch.
Eine
bekannte Form eines Getriebes ist ein Doppelkupplungsgetriebe, wie
das DSG-Getriebe im Audi TT. Ein typisches Doppelkupplungsgetriebe
ist schematisch in

Ein anderer bekannter Getriebetyp ist ein automatisiertes Schaltgetriebe (AMT), wie es beispielsweise von Alfa RomeoTM unter dem Handelsnamen „SelespeedTM" vertrieben wird. In einem automatisierten Schaltgetriebe verbinden sich eine einzige Kupplung und der dazu gehörige Zahnradsatz mit dem Zahnradsatz der Abtriebswelle. Wenn eine Schaltung erforderlich wird, öffnet sich die Kupplung, die neuen Gänge werden synchronisiert und die Kupplung schließt sich wieder. Ein Problem bei den AMT ist, dass es beim Gangwechsel zu einer erheblichen Drehzahlunterbrechung sowie einem schnellen Wechsel der Motorgeschwindigkeit kommt, wenn die Kupplung sich am Ende des Schaltvorgangs wieder schließt. Um diese Probleme zu beseitigen, wurde bei früheren Ansätzen versucht, den Synchronisierprozess zu beschleunigen, wodurch die zugehörigen Bauteile beschädigt werden können, oder die Motorgeschwindigkeit separat zu steuern, wodurch weitere Steueranforderungen notwendig werden könnten.Another known type of transmission is an automated manual transmission (AMT) marketed, for example, by Alfa Romeo ™ under the trade name "Selespeed ™ ." In an automated manual transmission, a single clutch and associated gear set mate with the output shaft gear set When a shift is required, the clutch opens, the new gears are synchronized, and the clutch closes again.A problem with the AMT is that when changing gear, a significant speed interruption and a rapid change in engine speed occurs when the clutch on the In order to overcome these problems, attempts have been made in earlier approaches to speed up the synchronization process, which may damage the associated components, or separately control the motor speed, which may necessitate further control requirements.
Die Erfindung bezieht sich auf die beigefügten Ansprüche.The The invention relates to the appended claims.
Da beim Doppelkupplungsgetriebe zwischen den Gangschaltungsmodi doppelte Schließung (wobei bei einem Schaltvorgang beide Kupplungen zumindest temporär gleichzeitig schließen) oder getrennte Schließung (wobei sich die beiden Kupplungen gegenseitig ausschließen) geschaltet werden kann, sind Schaltungen zwischen den Gängen mit einer einzigen Kupplung möglich, wobei Notlaufmöglichkeiten im Falle eines Bauteilfehlers zulässig sind. Zusätzlich zum AMT-Typ können Schaltungen zu jedem gewünschten Zeitpunkt mit reduziertem Drehmomentverlust/Änderungsauswirkung der Motordrehzahl (verglichen mit einer Standardübertragung eines Ein-Kupplungs-AMT) vorgenommen werden.There double in the dual-clutch transmission between the gearshift modes closure (Wherein at a switching operation both clutches at least temporarily simultaneously shut down) or separate closure (with the two clutches mutually exclusive) switched Circuits are between gears with a single clutch possible, where runflat possibilities in case of a component failure are permissible. In addition to AMT type can Circuits to any desired Time with reduced torque loss / change impact of the engine speed (compared to a standard transmission a one-clutch AMT) are made.
Ausführungsbeispiele der Erfindung werden nun mit Hilfe von Beispielen und Hinweis auf die Zeichnungen beschrieben.embodiments The invention will now be described with reference to examples and reference the drawings described.
Im Überblick bietet die Erfindung ein Getriebe, das frei umschaltbar ist zwischen einer konventionellen Drehmomentübertragung beim Schalttyp einer Doppelkupplung und einem Typ, bei dem sich die Kupplung oder die Kupplungen vor einem Gangwechsel komplett lösen und nach der Synchronisierung wieder schließen, so dass es zu einer getrennten, eher gleichzeitigen Schließung kommt. Das Ergebnis ist eine größere Flexibilität bei den möglichen Schaltungsmodi. AMT-artige Schaltungen werden verbessert, da es zu geringeren Drehmomentunterbrechungen kommt, weil die Synchronisierung eines zweiten Zahnradsatzes an der Abtriebswelle erreicht wird, während der erste Zahnradsatz noch immer geschlossen ist. Darüber hinaus können, falls ein Bauteil wie einer der Zahnradsätze versagt, die verbleibende Kupplung und der Zahnradsatz sich schließen und öffnen und Notfallreserven bieten.Overview the invention provides a transmission that is freely switchable between a conventional torque transmission when switching a double clutch and a type in which complete the clutch or clutches before changing gear solve and close again after synchronization, making it a separate, rather simultaneous closure comes. The result is greater flexibility in the potential Schaltungsmodi. AMT-type circuits are improved as it is to lower torque interruptions comes because the synchronization a second gear set is achieved on the output shaft, while the first gear set is still closed. Furthermore can, if a component such as one of the gear sets fails, the remainder Clutch and gear set close and open and provide emergency reserves.
Die

des DCT-Systems bei der Behandlung von Bauteilfehlern kann anhand
der
Bei
den Fehlerarten kann es sich beispielsweise um einen Aktorenfehler
handeln, der für
eine bestimmte Getriebestufe, einen Schaltstangenfehler oder einen
Kupplungsfehler zuständig
ist. Folglich hängt
die Steuerstrategie von der Art des Fehlers ab. Ein Beispiel wäre, wenn
eine einzelne Getriebestufe ausfällt.
In diesem Fall wird die Steuerstrategie die fehlerhafte Getriebestufe überspringen.
Wenn z.B. der zweite Gang ausfällt,
während
er ausgerückt
ist, wird die entsprechende Kupplung (Kupplung
Die fehlerhafte Getriebestufe kann durch Überwachen der Schaltstangenposition über den Schaltstangensensor und/oder die Drehzahl der Antriebswelle, die diese Synchronisierung nicht zeigt, entdeckt werden.The faulty gear stage can be detected by monitoring the shift rod position over the Shift rod sensor and / or the speed of the drive shaft, the this synchronization does not show will be discovered.
Alternativ
ist bei einem Schaltstangenfehler, wenn beispielsweise ein Gang
von der Abtriebswelle
Eine weitere Möglichkeit ist ein Fehler der Kupplung. Wenn die Kupplung in offener Position ausfällt, dann sind alle Gänge an der Antriebswelle blockiert und die andere Kupplung und Gänge werden in derselben Art und Weise wie bei einem Schaltstangenfehler eingesetzt. Der Fehler der Kupplung wird durch einen unkorrekten Kupplungsdruck durch den Kupplungsdruckfühler erkannt. Alternativ können auch konventionelle Steueralgorithmen, die den Betrieb des Systems bestimmen, den entsprechenden Steuerverlust aus unkorrekten oder widersprüchlichen Feedbacksignalen erkennen. Wenn die Kupplung im geschlossenen Zustand ausfällt, was auf ähnliche Art und Weise entdeckt wird, wird eine ähnliche Steuerstrategie eingesetzt, aber darüber hinaus wird eine AMT-artige Schaltung eingebaut, die die ausgefallene Kupplung löst, bevor die andere Kupplung und die entsprechenden Gänge eingerückt werden.A another possibility is a fault of the clutch. When the clutch is in the open position fails, then are all gears blocked on the drive shaft and the other clutch and gears are used in the same manner as a shift rod fault. The fault of the clutch is due to an incorrect clutch pressure through the clutch pressure sensor recognized. Alternatively you can also conventional control algorithms that control the operation of the system determine the corresponding tax loss from incorrect or contradictory Recognize feedback signals. When the clutch is in the closed state fails, what to similar ones Way is discovered, a similar control strategy is used, but about it In addition, an AMT-like circuit is installed, which the failed Clutch releases, before the other clutch and the corresponding gears are engaged.
Die Fehlerarten, die Art und Weise, wie der Fehler entdeckt wird, und die Steuerstrategie werden in folgender Tabelle detaillierter erläutert: The types of errors, the way in which the error is detected, and the control strategy are explained in more detail in the following table:
Zusätzlich zur Umsetzung der ungleichzeitigen Schließstrategie im Falle einer Fehlerentdeckung kann die Steuereinheit einem Befehl des Fahrers zur Umsetzung einer solchen Strategie nachkommen. Die Anforderung durch den Fahrer kann entweder eine spezifische Aufforderung des Fahrers über eine geeignete Schnittfläche sein, oder eine entdeckte Anforderung aus der Eingabe des Fahrers in Bezug auf beispielsweise die Gangschaltungen oder die Beschleunigungsanforderung.In addition to Implementation of the non-simultaneous closing strategy in the case of a fault detection The control unit may issue a command of the driver to implement a comply with this strategy. The requirement by the driver can either a specific request from the driver about a suitable cutting surface be, or a detected request from the input of the driver with respect to, for example, the gear shifts or the acceleration request.
Wenn
das DCT in den AMT-Modus schaltet, wie oben beschrieben, dann wird
an einem Schalthebel eine erste Kupplung voll gelöst, bevor
eine zweite Kupplung sich wieder schließt. Beim Hochschalten vom ersten
in den zweiten Gang – siehe
Als
Ergebnis kann die Schaltung erheblich schneller ausgeführt werden
und die Zugkraftunterbrechung wird entsprechend reduziert. Dies
wird anhand von
Es wird geschätzt, dass die Erfindung in Verbindung mit jedem Doppelschaltgetriebe angewendet werden kann, das über geeignete Sensoren und Aktoren verfügt, um ein geeignetes Steuersystem festzulegen, und mit einem passend konfigurierten mechanischhydraulischem Betätigungssystem ausgestattet ist. Die Erfindung kann, soweit erforderlich, auf jeden Motor- und Antriebstyp angewendet werden.It is estimated, that the invention in conjunction with any double gearbox that can be applied over suitable sensors and actuators to provide a suitable control system and with a suitably configured mechanical-hydraulic actuating system Is provided. The invention may, as necessary, apply to each Motor and drive type are applied.
