Description
Die Erfindung betrifft eine Vorrichtung mit einer Steuer- und/oder Regeleinheit nach dem Oberbegriff des Anspruchs 1 sowie ein Verfahren zum Betätigen einer Steuer- und/oder Regeleinheit nach dem Oberbegriff des Anspruchs 6.The The invention relates to a device with a control and / or regulating unit according to the preamble of claim 1 and a method for actuating a Control and / or regulating unit according to the preamble of the claim 6th
Aus dem Lehrbuch „Automatische Fahrzeuggetriebe" von Hans-Joachim Förster, erschienen im Springer-Verlag Berlin-Heidelberg 1991, S. 209 ff ist ein Verfahren zum Steuern einer als Kupplung ausgebildeten Drehmomentübertragungseinheit während eines Zughochschaltvorgangs unter Antriebsmoment bekannt. Um den Zughochschaltvorgang zu verkürzen und eine Wärmebelastung der Reibflächen der Kupplung zu mildern, wird vorgeschlagen, ein von einem Antriebsaggregat erzeugtes Drehmoment, beginnend mit einem Zeitpunkt nach einem Beenden einer Anlegephase, zu reduzieren, in dem die Kupplung das Drehmoment voll übernehmen kann. Zudem sind Vorrichtungen bekannt, in denen ein solches Verfahren realisierbar ist.Out the textbook "Automatic Vehicle transmission "from Hans-Joachim Förster, published in Springer-Verlag Berlin-Heidelberg 1991, p. 209 ff is a method for controlling a clutch trained torque transmission unit while a pull upshift under drive torque known. To the Shortening the traction control process and a heat load the friction surfaces To mitigate the clutch is proposed, one of a drive unit generated torque, starting with a time after termination a landing phase, in which the clutch reduces the torque fully take over can. In addition, devices are known in which such a method is feasible.
Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Vorrichtung und ein entsprechendes Verfahren mit einer wenigstens in einem Betriebsmodus verkürzten Reaktionszeit bereitzustellen. Sie wird gemäß der Erfindung durch die Merkmale des Anspruchs 1 und des unabhängigen Nebenanspruchs 6 gelöst. Weitere Ausgestaltungen ergeben sich aus den Unteransprüchen.Of the Invention is based on the object, a generic device and a corresponding method having at least one operating mode shortened To provide reaction time. It is according to the invention by the features of claim 1 and independent Nebenanspruchs 6 solved. Further embodiments emerge from the subclaims.
Die Erfindung geht aus von einer Vorrichtung mit einer Steuer- und/oder Regeleinheit, die zum Betätigen eines Antriebsaggregats während eines zumindest teilautomatisierten Schaltvorgangs einer Drehmomentübertragungseinheit unter Last und zur Reduktion eines Drehmoments des Antriebsaggregats in einem ersten Zeitpunkt des Schaltvorgangs vorgesehen ist.The The invention is based on a device with a control and / or Control unit to press a drive unit during an at least partially automated switching operation of a torque transmission unit under load and to reduce a torque of the drive unit is provided in a first time of the switching operation.
Es wird vorgeschlagen, dass die Steuer- und/oder Regeleinheit zur Reduktion des Drehmoments in wenigstens einem Betriebsmodus vor dem Beenden einer Anlegephase der Drehmomentübertragungseinheit in einem zweiten Zeitpunkt vorgesehen ist. Eine Reaktionszeit kann vorteilhaft verkürzt werden, da eine Reaktion schon zum ersten Zeitpunkt, in dem ein Drehmoment des Antriebs reduziert wird, als leichter Ruck in einem Antriebsstrang spürbar ist. Dieser Zeitpunkt kann in die Nähe eines Zeitpunkts gerückt werden, in dem die Vorrichtung ein Schaltsignal empfängt, während der zweite Zeitpunkt durch eine Dauer einer Füllphase und einer Anlegephase bestimmt ist. Diese Dauer ist nur unter einem großen technischen Aufwand verkürzbar. Einem Fahrer eines die Vorrichtung umfassenden Kraftfahrzeugs kann vorteilhaft ein Gefühl eines spontaneren Schaltvorgangs vermittelt werden. In einem weiteren Betriebsmodus kann das Drehmoment entsprechend dem beschriebenen Stand der Technik reduziert werden.It It is proposed that the control unit for reduction the torque in at least one operating mode before quitting an application phase of the torque transmission unit is provided at a second time. A reaction time can be shortened advantageous since a reaction already at the first time in which a torque the drive is reduced, as a slight jerk in a drive train noticeable is. This time can be moved close to a time, in which the device receives a switching signal during the second time by a duration of a filling phase and a landing phase is determined. This duration is only under a big technical Effort can be shortened. A driver of a vehicle comprising the device can beneficial a feeling a more spontaneous switching process are taught. In another operating mode can the torque according to the described prior art be reduced.
Es ist denkbar, dass die Steuer- und/oder Regeleinheit in eine umfassendere Einheit eines Kraftfahrzeugs integriert ist oder aber mehrere kommunizierende Untereinheiten aufweist, z.B. eine erste, dem Antrieb zugeordnete Untereinheit und/oder eine zweite, der Drehmomentübertragungseinheit zugeordnete Untereinheit. Dabei kann die Steuer- und/oder Regeleinheit zum Betätigen der Drehmomentübertragungseinheit und/oder des Motors entweder entsprechende Signale geben oder eine direkte Steuerung und/oder Regelung selbst vornehmen. Der zweite Zeitpunkt markiert den Beginn eines schnellen Schließvorgangs der Drehmomentübertragungseinheit und kann adaptiv zum Beispiel an einen Zustand der Drehmomentübertragungseinheit anpassbar sein. Der erste Zeitpunkt liegt eine einstellbare Zeitspanne vor dem zweiten Zeitpunkt. Die genannte Zeitspanne kann während des Betriebs der Steuer- und/oder Regeleinheit adaptiert werden. Die Last des Schaltvorgangs kann sowohl durch eine beschleunigende Kraft des Antriebsaggregats als auch durch einen Schub gegeben sein, wobei im letzteren Fall der Betrag des Drehmoments des Antriebsaggregats reduziert werden soll. Dies kann im Fall eines Schubs eines brennstoffbetriebenen Antriebsaggregats durch eine zwischenzeitliche Erhöhung der Brennstoffzufuhr erreicht werden, während im Fall einer beschleunigenden Kraft eine Reduktion des Drehmoments durch eine Reduktion der Brennstoffzufuhr und/oder durch ein Verstellen eines Zündzeitpunkts erreicht werden kann. Die Drehmomentübertragungseinheit kann als eine Kupplung, eine Bremse oder als eine andere dem Fachmann als sinnvoll erscheinende Drehmomentübertragungseinheit ausgebildet sein.It It is conceivable that the control and / or regulation unit should be more comprehensive Unit of a motor vehicle is integrated or several communicating Having subunits, e.g. a first, the drive assigned Subunit and / or a second, the torque transfer unit associated Subunit. In this case, the control and / or regulating unit for actuating the Torque transmission unit and / or the motor either give appropriate signals or one make direct control and / or regulation itself. The second Time marks the beginning of a fast closing process the torque transmission unit and may adaptively, for example, to a state of the torque transmitting unit be customizable. The first time is an adjustable period of time before the second time. The time period mentioned may be during the Operation of the control and / or regulating unit to be adapted. Weight The switching process can be achieved both by an accelerating force the drive unit as well as be given by a thrust, wherein in the latter case, the amount of torque of the power plant should be reduced. This can be in the case of a thrust of a fuel-powered Drive unit by an intermediate increase in the fuel supply be achieved while in the case of an accelerating force, a reduction of the torque by a reduction of the fuel supply and / or by an adjustment an ignition timing can be achieved. The torque transmission unit can as a clutch, a brake or any other than the one skilled in the art sensible torque transmission unit be educated.
In einer Ausgestaltung der Erfindung wird vorgeschlagen, dass der erste Zeitpunkt dem zweiten Zeitpunkt um weniger als 60 Millisekunden, insbesondere zwischen 20 und 40 Millisekunden vorausgeht. Dadurch kann vorteilhaft vermieden werden, dass die Reduktion des Drehmoments und das Ende der Anlegephase bzw. der anschließende schnelle Schließvorgang der Drehmomentübertragungseinheit als getrennte Vorgänge wahrnehmbar sind. Es kann erreicht werden, dass der Fahrer den Schaltvorgang vorteilhaft als zeitlich kompakt und kraftvoll empfindet. Eine merkliche Verkürzung der Reaktionszeit ist erreichbar, wenn der erste Zeitpunkt dem zweiten Zeitpunkt zwischen 80 und 100 Millisekunden vorausgeht.In An embodiment of the invention is proposed that the first Time at the second time by less than 60 milliseconds, in particular between 20 and 40 milliseconds. Thereby can be advantageously avoided that the reduction of torque and the end of the application phase or the subsequent fast closing process the torque transmission unit as separate operations are perceptible. It can be achieved that the driver is switching advantageous as temporally compact and powerful feels. A noticeable shortening the reaction time is achievable if the first time is the second Time between 80 and 100 milliseconds.
Prinzipiell ist ein Vorverlegen des ersten Zeitpunkts in allen Betriebsmodi aller dem Fachmann als sinnvoll erscheinenden wenigstens teilautomatisierten Drehmomentübertragungseinheiten möglich. Besondere Vorteile hinsichtlich eines Fahrgefühls ergeben sich jedoch beim Einsatz der erfindungsgemäßen Lösung zur Steuerung eines Schaltvorgangs in einem automatischen oder automatisierten Kraftfahrzeuggetriebe. Dem Fahrer kann, insbesondere in durch Sportlichkeit gekennzeichneten Betriebsmodi, vorteilhaft ein Gefühl von Dynamik vermittelt werden. Solche sportlichen Betriebsmodi weisen häufig eine durch hohen Druck beschleunigte Füllphase auf und sind zudem durch eine im Vergleich zu anderen Betriebsmodi erhöhte Schalthärte gekennzeichnet.in principle is an advancement of the first time in all modes of operation all of the skilled in the art appear reasonable at least partially automated Torque transmission units possible. However, special advantages in terms of a driving feeling arise when Use of the solution according to the invention for Control a switching operation in an automatic or automated Motor vehicle transmission. The driver can, especially in sportsmanship characterized modes of operation, advantageously a sense of dynamics mediated. Such sporting modes often have one high pressure accelerated filling phase on top of that and are moreover one in comparison to other operating modes increased switching hardness characterized.
Ist die Steuer- und/oder Regeleinheit insbesondere dann zur Steuerung des Schaltvorgangs vorgesehen, wenn es sich bei diesem um einen Zughochschaltvorgang handelt, kann vorteilhaft vermieden werden, dass eine Verlustleistung an der Drehmomentübertragungseinheit während des Zughochschaltvorgangs zu einer Beschädigung von Reibbelägen der Drehmomentübertragungseinheit durch ein Überhitzen führt.is the control and / or regulating unit in particular then for control the switching process provided, if this is a Zughochschaltvorgang is, can be advantageously avoided that a power loss at the torque transmitting unit during the Tough upshifting to damage of friction linings of Torque transmission unit by overheating leads.
Eine zusätzliche Verkürzung einer Reaktionszeit im ersten Betriebsmodus kann erreicht werden, wenn der erste Betriebsmodus zum Schließen der Drehmomentübertragungseinheit mit einer im Vergleich zu einem zweiten Betriebsmodus erhöhten Schließgeschwindigkeit vorgesehen ist. Im Falle hydraulisch betätigter Drehmomentübertragungseinheiten kann eine solche Beschleunigung konstruktiv einfach und robust durch einen erhöhten Druck in der Füllphase erreicht werden. Dadurch kann die Zeitspanne zwischen dem Schaltsignal und dem zweiten Zeitpunkt verkürzt werden.A additional shortening a reaction time in the first operating mode can be achieved when the first operating mode for closing the torque transmission unit with a higher closing speed compared to a second operating mode is provided. In the case of hydraulically actuated torque transmission units Such an acceleration can be constructively simple and robust an elevated one Pressure in the filling phase be achieved. This allows the time between the switching signal and the second time shortened become.
Fällt der erste Zeitpunkt mit einem Beginn der Anlegephase zusammen, kann vorteilhaft eine verfrühte Reduktion des Drehmoments zu einem Zeitpunkt, in dem die Drehmomentübertragungseinheit noch nicht zur Aufnahme von Drehmoment bereit ist, vermieden werden. Zudem kann vorteilhaft eine Greifpunktadaption, welche den Zeitpunkt des Beginns der Anlegephase bestimmt, zum Zweck einer Adaption des ersten Zeitpunkts genutzt werden. Toleranzen und Verschleißeffekte in der Drehmomentübertragungseinheit können vorteilhaft vermieden werden.Does that fall first time together with a start of the landing phase can advantageously a premature one Reduction of torque at a time when the torque transmission unit not yet ready to receive torque, be avoided. In addition, advantageously a gripping point adaptation, which is the time the beginning of the application phase, for the purpose of adapting the first time. Tolerances and wear effects in the torque transmission unit can be avoided advantageous.
