Description
Die Erfindung betrifft ein Verfahren zum Einstellen einer Drehmomentabgabe eines Antriebsstranges eines Kraftfahrzeuges, wobei eine Antriebsmaschine mit einer Antriebsseite eines Umschlingungsgetriebes wirkverbindbar ist und eine Abtriebsseite des Umschlingungsgetriebes mit antreibbaren Rädern oder dergleichen des Kraftfahrzeuges wirkverbunden ist.The invention relates to a method for setting a torque output of a drive train of a motor vehicle, a drive machine being operatively connectable to a drive side of a belt drive and an output side of the belt drive being operatively connected to drivable wheels or the like of the motor vehicle.
Stand der TechnikState of the art
Verfahren der gattungsgemäßen Art sind allgemein bekannt. So ist insbesondere bekannt, Verbrennungskraftmaschinen über elektronische Steuergeräte zu steuern, wobei drehmomentbeeinflussende Größen der Verbrennungskraftmaschine steuerbar sind. Hierbei können unter anderem die Steuerung einer Kraftstoffeinspritzung und/oder die Steuerung eines Zündwinkels erfolgen. Entsprechend eines gewünschten Motormanagements kann so ein Drehmomenteingriff in den Antriebsstrang des Kraftfahrzeuges erfolgen. Hierdurch wird auch eine Reduktion des Motormomentes möglich, wobei der Antriebsstrang dann maximal mit dem Schleppmoment der Verbrennungskraftmaschine abgebremst werden kann.Methods of the generic type are generally known. In particular, it is known to control internal combustion engines via electronic control devices, with torque-influencing variables of the internal combustion engine being controllable. Among other things, the control of a fuel injection and / or the control of an ignition angle can take place here. According to a desired engine management, a torque intervention in the drive train of the motor vehicle can take place. This also makes it possible to reduce the engine torque, with the drive train then being able to be braked at most with the drag torque of the internal combustion engine.

Vorteile der ErfindungAdvantages of the invention
Das erfindungsgemäße Verfahren mit den im Anspruch 1 genannten Merkmalen bietet den Vorteil, dass ein Drehmomenteingriff in den Antriebsstrang eines Kraftfahrzeuges, insbesondere ein negativer Drehmomenteingriff, schneller möglich ist. Dadurch, dass in Abhängigkeit vorgebbarer Betriebszustände des Antriebsstranges eines Kraftfahrzeuges durch Einstellen eines auf ein Umschlingungsmittel des Umschlingungsgetriebes wirkenden Anpressdruckes eine Drehmomentsteuerung erfolgt, insbesondere eine Verlustleistung für den Antriebsstrang aufgebracht wird, kann zusätzlich beziehungsweise gegebenenfalls anstelle eines Steuerns eines Zündwinkels beziehungsweise einer Kraftstoffeinspritzung der Verbrennungskraftmaschine die Drehmomentabqahe des Antriebsstranges beeinflusst werden. Über die Verlustleistung des Umschlingungsgetriebes lassen sich so insbesondere auch über das Schleppmoment der Verbrennungskraftmaschine hinausgehende negative Drehmomenteingriffe auf den Antriebsstrang realisieren.The method according to the invention with the features mentioned in claim 1 offers the advantage that a torque intervention in the drive train of a motor vehicle, in particular a negative torque intervention, is possible more quickly. Because a torque control takes place as a function of predeterminable operating states of the drive train of a motor vehicle by setting a contact pressure acting on a belt of the belt drive, in particular a power loss is applied to the drive train, the torque measurement can additionally or optionally instead of controlling an ignition angle or fuel injection of the internal combustion engine of the drive train can be influenced. In this way, negative torque interventions on the drive train that go beyond the drag torque of the internal combustion engine can be implemented via the power loss of the belt drive.
Bevorzugte Ausgestaltungen der Erfindung ergeben sich aus den übrigen, in den Unteransprüchen genannten Merkmalen.Preferred refinements of the invention result from the other features mentioned in the subclaims.

Beschreibung des AusführungsbeispielsDescription of the embodiment
Sowohl die Antriebsseite
Anhand der Kennlinien in
Diese grundsätzlichen Überlegungen und Zusammenhänge können nunmehr zum gezielten Beeinflussen der Drehmomentabgabe des Antriebsstranges
- - Antiruckelfunktion: Drehmomenteingriff, um Antriebsstrangschwingungen zu verhindern;
- - Lastschlagdämpfung: Drehmomentreduktion bei positiven Laständerungen zur Verhinderung eines unkomfortablen Lastschlages, auch bei Wiedereinsetzen nach einer Schubabschaltphase der Verbrennungskraftmaschine;
- - Leerlaufregelung: Drehzahlstabilisierung im Leerlauf;
- - Antischlupfregelung: Drehmomenteingriff, um ein Durchdrehen des/der Fahrzeugräder zu verhindern;
- - nmax-Begrenzung: Drehmomenteingriff, um ein Drehzahl überschwingen beziehungsweise eine Drehzahl oberhalb der Maximaldrehzahl der Verbrennungskraftmaschine zu verhindern;
- - Schalten eines Nebenaggregates (Verbraucher), beispielsweise eines Klimakompressors eines Kraftfahrzeuges: Momentenreduktion beim Zuschalten des Nebenaggregates, wobei hier zunächst langsam die Verlustleistung des Umschlingungsgetriebes erhöht wird, um diese dann im Zuschaltzeitpunkt des Nebenaggregates abzusenken;
- - Getriebeeingriff: beispielsweise zur Drehzahlsynchronisation beim Kupplungseinschalten des Getriebes;
- - Zylinderabschaltung: Verhinderung von unkomfortablen Drehmomentschwankungen beim Zu- beziehungsweise Abschalten einzelner Zylinder der Verbrennungskraftmaschine.
- - Anti-jerk function: torque intervention to prevent drive train vibrations;
- - Load shock damping: torque reduction in the event of positive load changes to prevent an uncomfortable load shock, even when restarting after an overrun cut-off phase of the internal combustion engine;
- - Idle control: speed stabilization when idling;
- - Anti-slip regulation: torque intervention to prevent the vehicle wheel (s) from spinning;
- - n max limitation: torque intervention in order to overshoot a speed or to prevent a speed above the maximum speed of the internal combustion engine;
- - Switching of an auxiliary unit (consumer), for example an air conditioning compressor of a motor vehicle: torque reduction when switching on the auxiliary unit, whereby the power loss of the belt drive is initially slowly increased, in order to then lower it at the time the auxiliary unit is switched on;
- Transmission intervention: for example for speed synchronization when the transmission is clutched;
- - Cylinder deactivation: Prevention of uncomfortable torque fluctuations when switching on or off individual cylinders of the internal combustion engine.
Zur Verdeutlichung ist die erste beschriebene Funktion, die Antiruckelfunktion, durch Zuschalten beziehungsweise Regeln der Verlustleistung des Umschlingungsgetriebes
Anhand
Die Ist-Drehzahl n14IST folgt somit dem vorgegebenen Verlauf der Soll-Drehzahl n14SOLL.The actual speed n 14IST thus follows the predetermined course of the target speed n 14SOLL .
Alternativ kann anstelle auf einen konstanten Verlauf der Drehzahl n auch auf einen konstanten Verlauf des Drehmomentes m an der Antriebsachse
Wie diese Regelung erfolgt, ist noch schematisch in
Bei dem vorstehend erläuterten Ausführungsbeispiel wurde Bezug genommen auf ein stufenlos einstellbares Umschlingungsgetriebe
Alles in allem lässt sich festhalten, dass durch die Erfindung eine genaue, feine Dosierbarkeit der Bremswirkung, das heißt insbesondere eines negativen Drehmomenteingriffs, möglich ist. Hierbei kann eine Variation der Verlustleistung des Umschlingungsgetriebes
