Description

Die Erfindung betrifft ein Verfahren gemäß dem Oberbegriff des Patent anspruchs 1. The invention relates to a method according to the preamble of claim 1.

Das Verhalten von Antriebssträngen mit automatischen Getriebe beim Abbremsen eines Kraftfahrzeugs bis zum Stillstand ist unter anderem durch folgende Punkte gekennzeichnet: The behavior of the drive trains with automatic transmission during braking of a motor vehicle to a standstill is characterized inter alia, by the following points:

  • - In den unteren Gängen von stufenweise schaltenden automatischen Getrieben werden häufig Freiläufe eingesetzt, damit ohne komplizierte Steuerstrategien ein guter Hochschaltkomfort erzielt wird. - In the lower gears of gradually switching automatic transmissions clutches are often used to make a good high shift comfort is achieved without complex control strategies. Diese Freiläufe müssen im Schubbetrieb durch zusätzliche Kupplungen überbrückt werden, was üblicherweise nur in niedrigen Fahrstufen, nicht aber im normalen Fahrbereich D erfolgt. These units must be bridged in the overrun mode with additional couplings, which usually takes place only at low speed steps, but not in normal D range.
  • - Als Anfahrelement wird meist ein hydraulischer Drehmomentwandler verwendet, der je nach seinem Drehzahlverhältnis Schub- oder Zugmomente überträgt. - As a starting element, a hydraulic torque converter is generally used that transfers depending on its speed ratio thrust or traction torques.

Typisch für den Anhaltevorgang bei Stufenautomatgetrieben ist, daß einerseits in den unteren Gängen das Fahrzeug mit der Betriebsbremse abgebremst werden muß, während der Motor weitgehend frei mit seiner Leerlaufdrehzahl dreht, und andererseits sich ein Kriechmoment aufbaut, sobald die Getriebe-seitige, dh die Turbinen-Drehzahl des Drehmomentwand lers die Motorleerlaufdrehzahl unterschreitet. is typical of the stopping operation at stage automatic transmissions that the vehicle must be braked with the service brake on the one hand in the lower gears, while the engine rotates substantially free with its idling speed, and on the other hand, a creep torque builds up, as soon as the transmission side, ie, the turbine speed of the torque wall toddlers, the engine idle speed is below. Dieses Verhalten ist in Fig. 4, obere beide Diagramme, verdeutlicht. This behavior is shown in Fig. 4, upper two diagrams, illustrates. Die Abszisse stellt die Zeitachse eines Anhaltevorgangs dar. Auf der Ordinate ist im obersten Diagramm das Verhältnis zwischen der Abtriebsdrehzahl des Drehmomentwandlers ω ab und der Leerlaufdrehzahl des Motors ω mot angegeben. The abscissa represents the time axis of a stopping operation. On the ordinate, the ratio between the output speed of the torque converter is in the uppermost diagram of ω, and given the idling speed of the engine ω mot. Im zweiten Diagramm gibt die Ordinate das Abtriebsmoment M ab des hydraulischen Drehmomentwand lers an, das sich bei Drehzahlgleichheit zwischen Abtriebsdrehzahl des Drehmomentwandlers und Leerlaufdrehzahl des Motors von einem Brems moment in ein Antriebsmoment umwandelt, das bei Fahrzeugstillstand (Abtriebsdrehzahl des Drehmomentwandlers = Null) als Kriechmoment sein Maximum erreicht. In the second diagram, the ordinate indicates the output torque M from the hydraulic torque wall toddlers at that moment converts at speed equality between the output speed of the torque converter and idle speed of the engine from a brake in a drive torque to be the vehicle stationary (output speed of the torque converter is zero) as creeping maximum reached.

Bei stufenlosen Automatikgetrieben ist üblicherweise kein Freilauf vorhanden, dh die Wandlerausgangsdrehzahl (Turbinendrehzahl) ist direkt vom Übersetzungsverhältnis des stufenlosen Getriebes bestimmt. In the continuously variable automatic transmissions no freewheel is usually present, ie the converter output speed (turbine speed) is determined directly from the gear ratio of the continuously variable transmission. Das bedeutet, daß der Abtriebsmomentverlauf beim Verzögern des Fahrzeugs durch das Zusammenwirken von Motorleerlaufdrehzahlregler und Übersetzungsregelung bestimmt wird. This means that the output torque curves for decelerating the vehicle is determined by the interaction of the engine idle speed regulator and translation control.

Fig. 3 beschreibt das Motorverhalten im Leerlaufbereich. Fig. 3 describes the engine behavior in the idling range. Die Abszisse gibt die Motordrehzahl ω, die Ordinate das Motormoment M mot an. The abscissa ω the engine speed, the ordinate mot the engine torque M on. ω mot ist wiederum die Leerlaufdrehzahl des Motors. mot ω turn is the idling speed of the engine. Oberhalb der Leerlaufdrehzahl ω mot gibt der Motor im Schubbetrieb ein Schubmoment ab, unterhalb der Leerlaufdrehzahl wird infolge des normalerweise vorhandenen Leerlaufreglers (elektronisch oder konventionell) ein zusätzliches Moment aufgebracht. Above the idling speed ω mot the engine is in the overrun mode from a thrust moment below the idle speed (electronic or conventional), an additional moment is applied due to the normally existing idle controller. Der Verlauf des Motormoments über Motordrehzahl ist je nach Reglerausführung unter schiedlich steil. The course of the engine torque from engine speed is differently steep, depending on the controller model below. Dieser Gradient hat einen erheblichen Einfluß auf den Abtriebsdrehmomentverlauf beim Anhalten. This gradient has a significant influence on the output torque curve when stopping.

Gibt die Übersetzungsregelung eines stufenlosen Getriebes eine Turbinen drehzahl vor, die größer als die Motorleerlaufdrehzahl ist, so stellt sich am Getriebeausgang ein Schubmoment ein, das dem Schubmoment des Motors, multipliziert mit der Getriebeübersetzung entspricht. Indicates the ratio control of a continuously variable transmission, a turbine speed before that is greater than the engine idle speed, as established at the transmission output a thrust moment a corresponding to the overrun torque of the motor, multiplied by the gear ratio. Ist durch die Überset zungsregelung die Turbinendrehzahl kleiner als die Motordrehzahl, so wird sich ein positives (Zug-)Moment ergeben, das wiederum abhängig ist von dem Moment aufgrund des Leerlaufreglers multipliziert mit der Drehmomentwand lung im Drehmomentwandler multipliziert mit der Übersetzung im stufenlosen Getriebe. Is determined by the gear ratio, control the turbine speed is less than the engine speed, then a positive (tensile) will result in torque that is in turn dependent multiplied by the moment due to the idle-speed controller to the torque wall lung in the torque converter multiplied by the gear ratio in the continuously variable transmission. Ist anstelle eines Drehmomentwandlers eine Kupplung eingesetzt, so gilt das vorher Gesagte, solange die Kupplung nicht schlupft. If instead of a torque converter, a clutch is used, the applicable foregoing, as long as the clutch does not slip. Läßt man die Kupplung - wie in der DE 39 39 660 A1 gezeigt - schlupfen, so wird in Abhängigkeit der Differenzdrehzahlrichtung Zug oder Schub in einer Höhe auftreten, die jeweils wieder vom Kupplungs moment - mit der Übersetzung des stufenlosen Getriebes multipliziert - abhängt. Allowed to the clutch - as described in DE 39 39 660 A1 shown - slip, then train or thrust occurring in dependence on the differential speed direction at a height, each back torque from the clutch - multiplied by the transmission ratio of the continuously variable transmission - dependent.

Werden keine besonderen Maßnahmen getroffen, so ergibt sich beim stufenlosen Getriebe durch das Fehlen von Freiläufen ein anderer Anhaltevor gang als beim Stufenautomaten. If no special measures are taken, a different Anhaltevor arises when continuously variable transmission by the absence of freewheels gang as they level machines. Ist der Motor aufgrund der Übersetzungs regelung des stufenlosen Getriebes im Schubbereich, so multipliziert sich das Schubmoment mit der Übersetzung des stufenlosen Getriebes. If the engine is due to the translation control of the continuously variable transmission in the thrust range, then the push torque multiplied by the translation of the continuously variable transmission. Für einen guten Ausrollkomfort wäre es also notwendig, die Übersetzung nicht zu groß zu wählen, was der Forderung widerspricht, beim Wiederbeschleunigen in einer möglichst großen Übersetzung zu sein. For a good Ausrollkomfort it would be necessary to choose the translation is not too large, the requirement is contrary to be the re-acceleration in the largest possible translation. Eine Übersetzungsverstellung im Stillstand des Fahrzeugs ist problematisch. A translation adjustment of the vehicle at a standstill is problematic.

Besonders schwierig werden die Verhältnisse bei stufenlosen Getrieben mit einer sogenannten Nullregel- oder Geared-Neutral-Struktur, wie sie beispielsweise aus den VDI-Berichten 579, Seiten 125-150 bekannt sind, bei der um den Anfahrpunkt die Übersetzung unendlich ist, so daß die Abtriebsmomentenver läufe besonders schwer steuerbar sind. be particularly difficult in the affairs of continuously variable transmissions with a so-called Nullregel- or geared-neutral structure, as they are known, for example from the VDI reports 579, pages 125-150, in order to approach point, the translation is infinite, so that the output torque Enver runs particularly difficult to control are.

Ein an sich bekanntes Getriebe mit einer solchen Geared-Neutral-Struktur ist in Fig. 5 schematisch dargestellt. A per se known gear with such a geared neutral structure is shown in Fig. 5 schematically. Es umfaßt eine Eingangswelle e und eine Ausgangswelle a. It includes an input shaft and an output shaft e a. An einem ersten Verzweigungsknoten 3 teilt sich der Übertragungspfad zwischen Eingangswelle und Ausgangswelle in zwei Pfade. At a first branch node 3, the transmission path between the input shaft and output shaft is divided into two paths. Der erste Pfad enthält eine Reibungskupplung K1, der eine Übersetzungsstufe 5 folgt, an die sich ein Differentialgetriebe 7 anschließt, dessen Ausgang über einen zweiten Verzweigungsknoten 9 mit der Ausgangswelle a verbunden ist. The first path includes a friction clutch K1, followed by a translation stage 5, to which a differential gear 7 connects, whose output is connected via a second branch node 9 is connected to the output shaft a.

Der zweite Übertragungspfad enthält ein stufenloses Getriebe CVT, beispiels weise ein Umschlingungsgetriebe mit zwei Scheiben veränderbaren Durch messers, dessen Ausgang über einen Knoten 11 mit einem Stützglied des Getriebes 7 verbunden und über eine zweite Reibungskupplung K2 mit dem zweiten Verzweigungsknoten 9 verbunden ist. The second transmission path includes a continuously variable transmission CVT, example, a continuously variable transmission with two slices of variable diameter, whose output is connected via a node 11 to a support member of the gear 7 and connected via a second friction clutch K2 with the second branch node. 9

Die Funktion des Getriebes gemäß Fig. 5 wird anhand Fig. 6 erläutert, bei der auf der Abszisse das Drehzahlverhältnis des gesamten Getriebes und auf der Ordinate das Drehzahlverhältnis des stufenlosen Getriebes aufgetragen sind. The function of the transmission shown in FIG. 5 will be explained with reference to FIG. 6, in which the abscissa represents the speed ratio of the entire transmission and the ordinate represents the speed ratio of the continuously variable transmission are applied. Dabei bedeuten: Where:
ν G das Drehzahlverhältnis des gesamten Getriebes, ν G, the speed ratio of the entire transmission,
ν CVT das Drehzahlverhältnis des stufenlosen Getriebes, ν CVT speed ratio of the continuously variable transmission,
ω a die Drehzahl der Ausgangswelle a, ω a is the speed of the output shaft a,
ω e die Drehzahl der Eingangswelle e und ω e is the rotation speed of the input shaft and e
ω Wa die Drehzahl der Abtriebswelle des stufenlosen Getriebes. Wa ω the rotational speed of the output shaft of the continuously variable transmission.

Im Bereich niedriger Gesamtdrehzahlverhältnisse ist die Kupplung K1 geschlossen und die Kupplung K2 geöffnet, wobei in der linken unteren Hälfte der Fig. 6 die Relativdrehzahl Δω K2e der Kupplung K2 angegeben ist. In the low overall speed ratios of the clutch K1 is engaged and the clutch K2 opened, whereby in the lower left half of FIG. 6, the relative rotational speed Δω K2 / ω e of the clutch K2 is indicated. Diese Relativdrehzahl nimmt bei abnehmendem Drehzahlverhältnis des stufenlosen Getriebes CVT ab und wird im dargestellten Beispiel bei dem Drehzahl verhältnis 0,45, dem Synchronpunkt des Getriebes, Null. This relative speed increases with decreasing speed ratio of the continuously variable transmission CVT, and is proportionate in the example shown at the speed of 0.45, the synchronization point of the gearbox zero. Bei Drehzahl verhältnissen ν G über 0,45 ist die Kupplung K2 geschlossen und die Kupplung K1 offen, wobei in der rechten unteren Hälfte der Fig. 6 die Relativdrehzahl an der Kupplung K1 angegeben ist. At speed ratios ν G than 0.45, the clutch K2 is closed and clutch K1 open, in the lower right half of FIG. 6, the relative speed is given to the clutch K1. Wie aus Fig. 6 weiter ersichtlich, vermindert sich das Übersetzungsverhältnis ν G des Getriebes bei einer Vergrößerung des Übersetzungsverhältnisses des stufenlosen Getriebes CVT und geschlossener Kupplung K1 zu immer kleineren Werten und nimmt schließlich bei einem Wert von 1,45 des Übersetzungsverhältnisses ν CVT den Wert Null an. As shown in Fig. 6 can further be seen, the transmission ratio ν G of the transmission decreases with an increase of the transmission ratio of the continuously variable transmission CVT and closed clutch K1 to ever smaller values, and finally ν CVT decreases at a value of 1.45 of the transmission ratio the value zero at. Wird das Übersetzungsverhältnis CVT weiter vergrößert, so nimmt ν G negative Werte an, dh die Ausgangswelle beginnt bei weiterem Vorwärtsdrehen der Eingangswelle rückwärts zu drehen. If the CVT speed ratio is increased further, ν G takes negative values, that is, the output shaft begins to rotate upon further forward rotation of the input shaft in reverse. Der Punkt, in dem das Übersetzungsverhältnis Null ist, wird als Neutralpunkt bezeichnet. The point at which the transmission ratio is zero is called the neutral point.

In Fig. 4, unten, ist der Abtriebsmomentenverlauf eines solchen Geared- Neutral-Getriebes ohne Vorhandensein eines Drehmomentwandlers gezeigt. In FIG. 4, below, the output torque characteristic of such Geared- neutral gear is shown without the presence of a torque converter. Ergibt die Übersetzungsregelung des stufenlosen Getriebes CVT der Fig. 5 exakt die Motorleerlaufdrehzahl, so ist auch das Abtriebsmoment exakt Null (Δ = Null). If the transmission ratio control of the continuously variable transmission CVT of Fig. 5 exactly the engine idle speed, so the output torque is exactly zero (Δ = zero). Bei dieser Betrachtung sind die Wirkungen von Massenbe schleunigungen und Massenverzögerungen in der Getriebestruktur ver nachlässigt. In this analysis, the effects of Massenbe are accelerations and ver neglected mass delays in the transmission structure. Liegt die von der Getriebeübersetzung bestimmte Motordrehzahl dagegen unter der Leerlaufdrehzahl, so wird sich ein Kriechmoment ergeben, das bei Vernachlässigung von Verlusten im Stillstand wegen der Drehmo mentübersetzung Unendlich betragen muß. If, however, the person designated by the transmission ratio, engine speed below the idling speed, then a creep torque is revealed the management Translation neglecting losses at a standstill because of the Torque must be infinity. Analog ergibt sich bei einer zu hoch eingeregelten Motordrehzahl ein Schubmoment, das ebenfalls gegen unendlich gehen kann. Analogously, at a too high the adjusted engine speed overrun torque that can also go to infinity.

Da die Motorleerlauf-Solldrehzahl von vielen Parametern abhängt und auch die gesamte Übersetzungsregelung des CVT-Getriebes toleranzbehaftet ist, ist der Anhaltevorgang bei Geared-Neutral-Getrieben ohne Zusatzmaßnahmen problematisch, es sei denn, man setzt, wie von Vahabzadeh, H.; Since the engine idling setpoint speed depends on many parameters and also the total speed control of the CVT transmission is subject to tolerances, the stopping operation at geared neutral gear without additional measures is problematic unless it is as of Vahabzadeh, H .; James, P.; James, P .; Dittrich, O.; Dittrich, O .; "Stufenloses Null-Regelgetriebe mit Leistungsverzweigung", 23. FISITA, Turin, 1990, beschrieben, Freiläufe ein. "Continuously variable zero control power-split transmission," 23 FISITA, Turin, 1990, describes a freewheels.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren anzugeben, mit dem sich der Anhaltevorgang eines mit einem stufenlosen, automatischen Getriebe versehenen Kraftfahrzeug bei geringem konstruktiven Aufwand in zufrieden stellender Weise steuern läßt. The invention has for its object to provide a method which can control the stopping operation of a provided with a continuously variable automatic transmission motor vehicle with a low constructional expenditure in a satisfactory manner.

Diese Aufgabe wird mit einem Verfahren gemäß dem Anspruch 1 gelöst. This object is achieved with a method according to the claim. 1

Durch die Kombination einer Übersetzungsregelung des stufenlosen Getriebes und einer Momentensteuerung der im Antriebsstrang schlupfenden Reibungs kupplung kann der Abtriebsmomentenverlauf, das ist der Drehmomentverlauf der fahrzeugseitig wirksamen Ausgangswelle des Getriebes, in einem weiten Bereich frei vorgegeben werden. By combining a transmission ratio control of the continuously variable transmission and a torque control of the slipping frictional clutch in the drive train of the output torque curve can, which is the torque curve of the vehicle-effective output shaft of the transmission can be freely set in a wide range.

Eine solche Reibungskupplung ist bei stufenlosen Getrieben entweder als Anfahrkupplung oder als Bereichswechselkupplung vorhanden. Such friction clutch is present at variable transmissions either as a start or a range change clutch. Besonders vorteilhaft ist, wenn die schlupfende Kupplung zwischen dem stufenlosen Getriebe und dem Abtrieb liegt, da dann das Abtriebsmoment nicht das Kupplungsmoment multipliziert mit der Getriebeübersetzung ist, sondern direkt das Kupplungsmoment. It is particularly advantageous if the slip clutch between the continuously variable transmission and the output is, since then the output torque, the clutch torque does not multiplied with the gear ratio is, but directly the clutch torque. Unter Berücksichtigung der jeweiligen Getriebe übersetzung läßt sich jedoch auch eine antriebsseitige Reibungskupplung entsprechend dem gewünschten Abtriebsmoment steuern. Taking into consideration the respective gear ratio, however, a drive-side friction clutch corresponding to the desired output torque can be controlled.

Die Unteransprüche sind auf vorteilhafte Durchführungsformen des erfin dungsgemäßen Verfahren gerichtet. Dependent claims are directed at advantageous implementation forms of OF INVENTION to the invention process.

Insgesamt wird mit der Erfindung erreicht, ohne die Notwendigkeit des Einbaus von Freiläufen einen zufriedenstellenden Abtriebsmomentenverlauf zu erzielen. Overall, it is achieved with the invention to achieve a satisfactory output torque curve without the need of installation of freewheels.

Die Erfindung wird im folgenden anhand schematischer Zeichnungen beispielsweise und mit weiteren Einzelheiten erläutert. The invention will be explained in the following with reference to schematic drawings, for example, and with further details.

Fig. 6 Diagramme zur Erläuterung der Funktionsweise des Geared- Neutral-Getriebes gemäß Fig. 5. Fig. 6 are diagrams for explaining the operation of the Geared- neutral transmission according to Fig. 5.

Die Abszisse der Fig. 1 bedeutet ähnlich wie die der bereits erläuterten Fig. 4 die Zeitachse während eines Anhaltevorgangs. The abscissa of Fig. 1 is similar to that of the already explained Fig. 4, the time axis during a stopping operation. Die oberste Gerade zeigt den Verlauf des Drehzahlverhältnisses ν G = Drehzahl ω a der Ausgangswelle a ( Fig. 5) zu Drehzahl ω e der Eingangswelle e während des Anhaltevorgangs. The top straight line shows the variation of the speed ratio ν G = speed ω a of the output shaft a (Fig. 5) to rotational speed ω e of the input shaft e during the stopping operation.

Die mittleren zueinander parallelen Geraden gemäß Fig. 1 geben Beispiel für einen Verlauf der Drehzahldifferenz Δω zwischen Leerlaufdrehzahl des Motors ω mot und Drehzahl ω e der Eingangswelle während eines Anhaltevorgangs an. The mean mutually parallel straight lines in FIG. 1 give example of a course of the rotational speed difference Δω between idling speed of the engine ω mot and rotational speed ω e of the input shaft during a stopping operation. Die mittlere durchgezogene Gerade entspricht dem Fall, bei dem ω mot und ω e so aufeinander abgestimmt sind, daß sie bei der Getriebeübersetzung 1 miteinander übereinstimmen. The mean solid straight line corresponds to the case where ω mot and ω e are matched to one another so that they coincide with each other in the transmission ratio. 1 Bei der strichpunktierten oberen Gerade ist die Leerlaufdrehzahl hoch bzw. die Übersetzungsregelung des Getriebes nicht ideal auf die Motordrehzahl abgestimmt. In the upper dash-dot straight line, the idle speed is high and matched the translation control of the transmission is not ideal to the engine speed. Bei der gestrichelten Kurve ist die Getriebeübersetzung so, daß die Drehzahl der Getriebeeingangswelle bereits bei Getriebedrehzahlverhältnissen über 1 gleich der Leerlaufdrehzahl ist. In the dashed curve, the gear ratio is such that the rotational speed of transmission input shaft even at transmission speed ratios above 1 is equal to the idling speed. Die untersten Kurven der Fig. 1 zeigen die sich einstellenden Abtriebsmomente an der Antriebswelle a, wobei das maximale Abtriebsmoment (Kriechmoment M K1 ) durch die Ansteuerung der Kupplung K1 festgelegt ist. The lowermost curves of FIG. 1 show the self-adjusting output torque to the drive shaft a, the maximum output torque (M creep K1) by the actuation of the clutch is set to K1. Wie unmittelbar ersichtlich, kann durch entsprechende Regelung der Getriebeübersetzung und Ansteuerung der Kupplung K1 weitgehend jeder vorgebbare Verlauf des Abtriebsmoments, übergehend von einem Bremsmoment (links in Fig. 1) zu einem Antriebs- bzw. Kriechmoment (rechts in Fig. 1) erzeugt werden. As is immediately apparent, the clutch K1 can be generated largely every predetermined curve of the output torque temporarily by a braking torque (the left in FIG. 1) to a drive or creeping torque (to the right in Fig. 1) by appropriate control of the transmission ratio and control. Dabei ist die Übersetzung des Getriebes bei Fahrzeugstillstand, die für die Anfahr dynamik wichtig ist, ebenfalls innerhalb weiter Grenzen variierbar. Here, the ratio of the transmission when the vehicle stops, the momentum for the startup is important also varied widely.

Fig. 2 zeigt eine Gesamtanordnung zur Durchführung des anhand Fig. 1 geschilderten Verfahrens. Fig. 2 shows a total arrangement for carrying out the described with reference to FIG. 1 process.
