Abstract
Description
Die Erfindung betrifft ein Verfahren zur Schwingungsdämpfung in einem Antriebsstrang eines Fahrzeuges gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a method for vibration damping in a drive train of a vehicle according to the preamble of claim 1.
Üblicherweise wird eine aktiv geregelte Kupplung in einem Antriebsstrang eines Fahrzeuges in einem so genannten dauerschlupfenden Betriebszustand betrieben. Diese Kupplung wird durch einen Regler gesteuert, welcher sich aufschwingen kann. Während der Fahrzeugentwicklung wird dieser Regler so abgestimmt, dass er sich möglichst nicht aufschwingt. Bei Anregungen von außerhalb des Fahrzeugs kann diese herkömmliche Abstimmung des Reglers aber nicht immer das Auftreten einer Schwingung im Antriebsstrang eines Fahrzeuges verhindern.Usually, an actively controlled clutch is operated in a drive train of a vehicle in a so-called permanent slipping operating state. This clutch is controlled by a regulator, which can swing up. During vehicle development, this controller is tuned so that it does not swing up as possible. However, with suggestions from outside the vehicle, this conventional tuning of the controller may not always prevent the occurrence of vibration in the powertrain of a vehicle.
Der Erfindung liegt die Aufgabe zu Grunde, ein gegenüber dem Stand der Technik verbessertes Verfahren zur Schwingungsdämpfung in einem Antriebsstrang eines Fahrzeuges anzugeben.The invention is based on the object to provide a comparison with the prior art improved method for vibration damping in a drive train of a vehicle.
Hinsichtlich des Verfahrens zur Schwingungsdämpfung in einem Antriebsstrang eines Fahrzeuges wird die Aufgabe durch die im Anspruch 1 angegebenen Merkmale gelöst.With regard to the method for vibration damping in a drive train of a vehicle, the object is achieved by the features specified in claim 1.
Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.Advantageous embodiments of the invention are the subject of the dependent claims.
Beim Verfahren zur Schwingungsdämpfung in einem Antriebsstrang eines Fahrzeuges, wobei der Antriebsstrang eine aktiv geregelte Kupplung und/oder eine Wandlerüberbrückungskupplung umfasst, wird erfindungsgemäß ein Drehzahlsignal zumindest eines der aktiv geregelten Kupplung zugeordneten Drehzahlsensors erfasst und ausgewertet, wobei bei einer anhand der Auswertung erkannten Schwingung im Antriebsstrang ein Regelvorgang der aktiv geregelten Kupplung aktuiert wird. Dadurch sind vorteilhafterweise für Fahrzeuginsassen wahrnehmbare Schwingungen im Antriebsstrang verringerbar, so dass ein Fahrkomfort des Fahrzeugs erhöht ist.In the method for vibration damping in a drive train of a vehicle, wherein the drive train comprises an actively controlled clutch and / or a lockup clutch according to the invention, a speed signal of at least one of the actively controlled clutch associated speed sensor is detected and evaluated, wherein at a detected by the evaluation vibration in the drive train a control action of the actively controlled clutch is actuated. As a result, perceivable vibrations in the drive train can advantageously be reduced for vehicle occupants, so that a driving comfort of the vehicle is increased.
Besonders vorteilhafterweise kann eine Schwingungsstärke ermittelt und eine entsprechend gesteuerte und/oder geregelte Gegenmaßnahme ergriffen werden, welche die Schwingung verhindern oder zumindest die Schwingungsstärke verringern.Particularly advantageously, a vibration intensity can be determined and a correspondingly controlled and / or regulated countermeasure taken, which prevent the vibration or at least reduce the vibration intensity.
Ausführungsbeispiele der Erfindung werden im Folgenden anhand von Zeichnungen näher erläutert.Embodiments of the invention are explained in more detail below with reference to drawings.

Einander entsprechende Teile sind in allen Figuren mit den gleichen Bezugszeichen versehen.Corresponding parts are provided in all figures with the same reference numerals.
Das erfindungsgemäße Verfahren betrifft eine Regelung eines Antriebsstrangs eines Fahrzeuges zur Dämpfung auftretender Schwingungen. Ein solcher herkömmlicher, nicht dargestellter Antriebsstrang umfasst zumindest einen Verbrennungsmotor, welcher mittels einer Kupplung kraftschlüssig mit einem Getriebe verbindbar ist, das Getriebe und eine Kardanwelle, welche eine Antriebskraft an eine Antriebsachse überträgt. Dabei wirkt der Verbrennungsmotor auf eine Getriebeeingangswelle ein und die Kardanwelle ist mechanisch mit einer Getriebeausgangswelle gekoppelt.The inventive method relates to a control of a drive train of a vehicle for damping vibrations occurring. Such a conventional, not shown drive train comprises at least one internal combustion engine, which is frictionally connected by means of a clutch with a transmission, the transmission and a propeller shaft, which transmits a driving force to a drive axle. In this case, the internal combustion engine acts on a transmission input shaft and the propeller shaft is mechanically coupled to a transmission output shaft.
Die Kupplung ist vorzugsweise als herkömmliche, aktiv geregelte Kupplung und/oder als eine Wandlerüberbrückungskupplung eines automatischen Getriebes ausgebildet und zwischen dem Verbrennungsmotor und der Getriebeeingangswelle angeordnet. Dabei wird die Kupplung mittels eines pneumatisch, elektrisch und/oder hydraulisch betätigbaren Aktors von einem Getriebesteuergerät gesteuert und/oder geregelt. Das automatische Getriebe kann beispielsweise als ein Zahnräderwechselgetriebe mit einer Doppelkupplung (Doppelkupplungsgetriebe) oder als ein Getriebe mit gekoppelten Planetensätzen ausgebildet sein.The clutch is preferably designed as a conventional, actively controlled clutch and / or as a lockup clutch of an automatic transmission and disposed between the engine and the transmission input shaft. In this case, the clutch is controlled and / or regulated by means of a pneumatically, electrically and / or hydraulically actuatable actuator by a transmission control unit. The automatic transmission may be formed, for example, as a change-speed gearbox with a dual clutch (dual-clutch transmission) or as a transmission with coupled planetary gear sets.
Schwingungen treten in Betrieb des Antriebsstrangs durch äußere und innere Anregungen auf. Dabei werden äußere Anregungen beispielsweise durch einen Straßenbelag, einen Fahrzeugreifen oder Fahrwerksbewegungen auf den Antriebsstrang aufgeprägt. Innere Anregungen sind beispielweise Vibrationen des Verbrennungsmotors, der Kupplung und/oder des Getriebes. Insbesondere Vibrationen unterschiedlicher Intensität des Verbrennungsmotors, der Kupplung und/oder des Getriebes bewirken durch die mechanische Koppelung des Gehäuses des Verbrennungsmotors und des Gehäuses des Getriebes Schwingungen im Antriebsstrang.Vibrations occur in operation of the powertrain through external and internal excitations. In this case, external stimuli are impressed on the drive train, for example, by a road surface, a vehicle tire or chassis movements. Internal suggestions are, for example, vibrations of the internal combustion engine, the clutch and / or the transmission. In particular, vibrations of varying intensity of the internal combustion engine, the clutch and / or the transmission cause by the mechanical coupling of the housing of the internal combustion engine and the housing of the transmission vibrations in the drive train.
Das Drehzahlsignal n1 der Antriebswelle der Kupplung ist die Drehzahl des Verbrennungsmotors, mit welcher die Kupplung im Betrieb eingangsseitig beaufschlagt wird. Zur Erfassung dieses Drehzahlsignal n1 ist ein herkömmlicher Drehzahlsensor an der Antriebswelle der Kupplung angeordnet.The speed signal n 1 of the drive shaft of the clutch is the speed of the internal combustion engine, with which the clutch is acted on the input side during operation. To detect this speed signal n 1 , a conventional speed sensor is arranged on the drive shaft of the clutch.
Das Drehzahlsignal n2 der Abtriebswelle der Kupplung ist die Drehzahl, mit welcher die Getriebeeingangswelle im Betrieb des Antriebsstrangs beaufschlagt wird. Zur Erfassung dieses Drehzahlsignals n2 ist ein herkömmlicher Drehzahlsensor an der Abtriebswelle der Kupplung angeordnet.The speed signal n 2 of the output shaft of the clutch is the speed at which the transmission input shaft is acted upon during operation of the drive train. For detecting this speed signal n 2 , a conventional speed sensor is arranged on the output shaft of the clutch.
Das Schwingungssignal S repräsentiert eine mittels des erfindungsgemäßen Verfahrens ermittelte Schwingung des Antriebsstrangs.The vibration signal S represents an oscillation of the drive train determined by means of the method according to the invention.
Der Kupplungsdruck PD ist ein Betätigungsdruck der aktiv geregelten Kupplung, welcher mittels eines herkömmlichen Kupplungsdrucksensors ermittelt wird.The clutch pressure P D is an actuating pressure of the actively controlled clutch, which is determined by means of a conventional clutch pressure sensor.
Im Betrieb des Antriebsstrangs wird zumindest eines der oder werden beide Drehzahlsignale n1 und n2 fortlaufend erfasst und einer Auswerteeinheit

Analog zur beschriebenen Ermittlung der Schwingung S1 für das Drehzahlsignal n1 der Antriebswelle der Kupplung kann eine Schwingung S2 für das Drehzahlsignal n2 der Antriebswelle der Kupplung ermittelt werden.Analogous to the described determination of the oscillation S 1 for the speed signal n 1 of the drive shaft of the clutch, a vibration S 2 for the speed signal n 2 of the drive shaft of the clutch can be determined.
