Abstract
Description
Die Erfindung betrifft eine Vorrichtung zur Steuerung einer zwischen einem Verbrennungsmotor und einem Automatikgetriebe in einem Kraftübertragungssystem eines Kraftfahrzeugs befindlichen Kupplung, gemäß dem Oberbegriff des Anspruchs 1. Die Erfindung betrifft weiterhin ein entsprechendes Verfahren.The invention relates to a device for controlling a clutch located between an internal combustion engine and an automatic transmission in a power transmission system of a motor vehicle, according to the preamble of claim 1. The invention further relates to a corresponding method.
Eine gattungsgemäße Vorrichtung ist aus der
Die Aufgabe der Erfindung besteht darin, die gattungsgemäße Vorrichtung universeller auszugestalten.The object of the invention is to design the generic device universal.
Die Aufgabe wird gelöst durch die Merkmale des Anspruchs 1. Die Unteransprüche betreffen vorteilhafte Aus- und Weiterbildungen der Erfindung.The object is achieved by the features of claim 1. The subclaims relate to advantageous embodiments and further developments of the invention.
Erfindungsgemäß ist ein manuell betätigbares Bedienelement vorgesehen, bei dessen Betätigung die Schlupfsteuereinrichtung, zum Ausführen einer Schlupfsteuerung einer zwischen dem Verbrennungsmotor und dem Automatikgetriebe des Kraftübertragungssystems des Kraftfahrzeuges befindlichen Kupplung, während einer Verzögerung des Kraftfahrzeuges die Schlupfgröße der Kupplung derart steuert, dass der Verbrennungsmotor auf einer Drehzahl gehalten wird bei welcher eine Schubabschaltung des Verbrennungsmotors vorgesehen ist. Die Schubabschaltung bedeutet dabei eine Unterbrechung der Kraftstoffzufuhr zum Verbrennungsmotor. Anders ausgedrückt ermöglicht die Erfindung quasi die Herbeiführung der Schubabschaltung des Verbrennungsmotors, indem vermittels der manuelle Betätigung des Bedienelements durch den Fahrer die dafür nötigen Voraussetzungen bereitgestellt werden. Beim Vorliegen dieser Voraussetzungen wird von der Motorsteuerung des Verbrennungsmotors sodann automatisch die Schubabschaltung ausgelöst, ohne dass hierzu eine aufwendige Situationserkennung oder Signalauswertung notwendig wäre. Eine derartige Situation liegt beispielsweise vor, wenn das Kraftfahrzeug einen leichten Berg hinunter fährt oder wenn es mit definierter Geschwindigkeit fährt. Dabei wird jedoch keine kostspielige und fehleranfällige automatische Situationserkennung versucht, sondern vielmehr ist erfindungsgemäß eine manuelle Betätigung durch den Fahrer des Kraftfahrzeuges vorgesehen wenn dieser eine derartige Situation als gegeben ansieht.According to the invention, a manually operable control element is provided, upon actuation of which the slip control device controls a slip control of a clutch located between the internal combustion engine and the automatic transmission of the power transmission system of the motor vehicle during a deceleration of the motor vehicle such that the internal combustion engine is at a speed is held at which a fuel cut of the engine is provided. The fuel cutoff means an interruption of the fuel supply to the engine. In other words, the invention makes it possible, as it were, to bring about the fuel cutoff of the internal combustion engine by providing the necessary conditions for this by means of the manual actuation of the operating element by the driver. If these conditions are met, the engine control system of the internal combustion engine then automatically triggers the overrun fuel cutoff without the need for complex situation recognition or signal evaluation. Such a situation exists, for example, when the motor vehicle is driving down a slight hill or when it is traveling at a defined speed. However, no costly and error-prone automatic situation detection is attempted, but rather a manual operation by the driver of the motor vehicle is provided according to the invention when viewing such a situation as given.
Besonders vorteilhaft an diesem erfindungsgemäßen Vorgehen ist, dass durch die gezielte Kupplungssteuerung die Voraussetzungen für eine minimale Drehzahl des Verbrennungsmotors bereitgestellt werden können, beispielsweise eine Drehzahl knapp oberhalb der Leerlaufdrehzahl. Gegenüber einer herkömmlichen Schubabschaltung, mit höherer Drehzahl und somit höherem Reibungsmoment, ergeben die verringerte Drehzahl des Verbrennungsmotors eine weitere Verringerung des Reibmoments. Damit resultiert die erfindungsgemäße Schubabschaltung in einem noch geringeren Geschwindigkeitsverlust des Kraftfahrzeuges, und somit einer erhöhten Kraftstoffeinsparung, da noch längere Distanzen ohne Kraftstoffzufuhr zum Verbrennungsmotor zurückgelegt werden können.A particular advantage of this approach according to the invention is that the conditions for a minimum speed of the internal combustion engine can be provided by the targeted clutch control, for example, a speed just above the idle speed. Compared to a conventional fuel cut, with higher speed and thus higher friction torque, the reduced speed of the engine result in a further reduction of the friction torque. This results in the inventive fuel cut in an even lower loss of speed of the motor vehicle, and thus an increased fuel economy, as even longer distances without fuel supply to the engine can be covered.
Beim Verbrennungsmotor kann es sich insbesondere um eine mit Benzin oder Diesel nach einem beliebigen Brennverfahren betriebene Brennkraftmaschine handeln. Als Automatikgetriebe sollen dabei sowohl Getriebe mit hydrodynamischem Wandler als auch Doppelkupplungsgetriebe verstanden werden. Als entsprechende Kupplung, zur Ansteuerung durch die Schlupfsteuereinrichtung, sind dabei vorzugsweise eine Wandlerüberbrückungskupplung bzw. diejenige Kupplung des Doppelkupplungsgetriebes welche dem Teilgetriebe mit gerade eingelegtem Gang zugeordnet ist, vorgesehen. Als Verzögerung des Kraftfahrzeuges soll dabei eine nicht beschleunigte Fahrsituation betrachtet werden. In diesem Falle wird das Kraftfahrzeug nämlich durch verschiedene Widerstände, beispielsweise Rollwiderstand, Luftwiderstand, usw., verzögert.The internal combustion engine may in particular be an internal combustion engine operated with gasoline or diesel according to any combustion method. As automatic transmission to be understood both gearbox with hydrodynamic converter and dual clutch transmission. As a corresponding clutch, for driving through the slip control device, preferably a torque converter lock-up clutch or that clutch of the dual-clutch transmission which is associated with the partial transmission with just engaged gear, are provided. As a delay of the motor vehicle while a non-accelerated driving situation should be considered. In this case, the motor vehicle is namely delayed by various resistances, such as rolling resistance, air resistance, etc.
Bevorzugt ist das manuell betätigbare Bedienelement als Taste ausgebildet, insbesondere am Lenkrad oder im Bereich der Mittelkonsole. Eine derartige Taste ist vom Fahrer einfach zu erreichen, was eine häufige Aktivierung der erfindungsgemäßen Schubabschaltung fördert. Eine Deaktivierung der erfindungsgemäßen Schubabschaltung ist dabei bevorzugt dann vorgesehen, wenn der Fahrer im Anschluss an eine Aktivierung das Gaspedal betätigt. Damit wird das Kraftfahrzeug beschleunigt und somit die Kupplungssteuerung deaktiviert. Weitere Möglichkeiten der Deaktivierung bestehen darin, dass der Fahrer das Bedienelement erneut betätigt. Alternativ kann das Bedienelement auch als Schalter ausgebildet sein, welches die erfindungsgemäße Kupplungssteuerung ein- bzw. ausschaltet. Zum Schutz der Kupplung kann zusätzlich noch eine Temperaturüberwachung vorgesehen sein, wobei beim Überschreiten einer Grenztemperatur der Kupplung eine Deaktivierung der erfindungsgemäßen Kupplungssteuerung vorgesehen ist.Preferably, the manually operable control element is designed as a button, in particular on the steering wheel or in the region of the center console. Such a button is easy to reach by the driver, which promotes frequent activation of the fuel cut-off according to the invention. A deactivation of the fuel cutoff according to the invention is preferably provided when the driver actuates the accelerator pedal after an activation. This accelerates the motor vehicle and thus deactivates the clutch control. Other ways of deactivation are that the driver operates the control again. Alternatively, the control element can also be designed as a switch which switches the clutch control according to the invention on or off. To protect the clutch may additionally be provided a temperature monitoring, wherein when exceeding a limit temperature of the clutch deactivation of the clutch control according to the invention is provided.
