Die Erfindung betrifft eine Antriebseinrichtung für ein Kraftfahrzeug gemäß dem Oberbegriff des Patentanspruchs 1 sowie ein Verfahren zum Betreiben einer solchen Antriebseinrichtung gemäß dem Oberbegriff des Patentanspruchs 5.The The invention relates to a drive device for a motor vehicle according to the preamble of Patent claim 1 and a method for operating such Drive device according to the preamble of claim 5.

Derartige Geschwindigkeitsregelanlagen verfügen neben anderen Sensoren unter anderem über einen Kupplungspedalschalter, der der Regelanlage anzeigt, wann eine Kupplungsbetätigung vorliegt. In einem solchen Fall wird die Funktion der Geschwindigkeitsregelanlage abgeschaltet, um einen komfortablen Gangwechsel zu ermöglichen. Zudem wird die Funktion der Geschwindigkeitsregelanlage auch unter anderen Bedingungen abgeschaltet, beispielsweise wenn durch den Fahrer die Brennkraftmaschine stillgesetzt wird.such Cruise control systems have, among other sensors among others about a clutch pedal switch that indicates to the control system when a clutch operation is present. In such a case, the function of the cruise control system switched off to allow a comfortable gear change. In addition, the function of the cruise control system is also under switched off other conditions, for example, if by the Driver the internal combustion engine is shut down.
Bei gattungsgemäßen Kraftfahrzeugen, die in jüngster Zeit als Ecomatic-Fahrzeuge oder als Fahrzeuge mit Schwungnutz-Automatik bekannt geworden sind, ist die Kupplungsbetätigung automatisiert und deswegen kein gesondertes Kupplungspedal und somit auch kein Kupplungspedalschalter vorgesehen.at generic motor vehicles, the most recent Time as Ecomatic vehicles or as vehicles with inertia automatic have become known, the clutch operation is automated and therefore no separate clutch pedal and thus no clutch pedal switch intended.
Da bei einem funktionsgerechten Betrieb eines solchen Kraftfahrzeuges, beispielsweise auf Ausrollstrecken, die Brennkrafimaschine aus dem Antriebsstrang herausgekuppelt und stillgesetzt wird, würde eine einfache additive Implementierung einer Geschwindigkeitsanlage in ein derartiges Fahrzeug die Geschwindigkeitsregelanlage bei antriebslosen Fahrbetriebsphasen ständig stillsetzen, da diese nach dem Stand der Technik bei stillstehendem Motor automatisch abgeschaltet wird.There in a functional operation of such a motor vehicle, for example on Ausrollstrecken, the fuel engine from the drive train disengaged and shut down, would be a simple additive Implementation of a speed system in such a vehicle the Cruise control system during non-driving driving phases constantly shut down, since these according to the prior art at a standstill Engine is switched off automatically.

Die Aufgabe der Erfindung besteht daher darin, eine gattungsgemäße Antriebseinrichtung und ein gattungsgemäßes Verfahren derart auszubilden, dass damit Geschwindigkeitsregelfunktionen komfortabel ausführbar sind.The The object of the invention is therefore a generic drive device and a generic method such that it speed control functions comfortable executable are.
Die Lösung dieser Aufgabe ergibt sich aus den unabhängigen Ansprüchen 1 und 5, während vorteilhafter Ausgestaltungen der Erfindung den abhängigen Ansprüchen entnehmbar sind.The solution This object is apparent from the independent claims 1 and 5, while more advantageous Embodiments of the invention the dependent claims are.
Eine gattungsgemäße Antriebseinrichtung wird demnach so weitergebildet, dass das Steuergerät für die antriebslosen Fahrbetriebsphasen mit einer Geschwindigkeitsregelanlage über Daten- und/oder Steuerleitung in Verbindung steht, über die der Leistungswunsch des Fahrers, die Kupplungsbetätigung, die Kurbelwellen- und die Getriebeeingangswellendrehzahl, die Gangwahlhebelaktivierung, der Betriebszustand der Geschwindigkeitsregelanlage und des Steuergerätes für die antriebslosen Fahrbetriebsphasen sowie die vorgewählte und zu regelnde Fahrgeschwindigkeit signalisierbar sind.A generic drive device is Accordingly, further developed such that the control unit for the non-driving driving phases with a cruise control system via data and / or control line communicates, about the driver's desire for performance, the clutch actuation, the crankshaft and the transmission input shaft speed, the gear selector lever activation, the operating status of the speed control system and the control unit for the non-powered Driving phases and the preselected and regulated vehicle speed can be signaled.
Wenngleich der Einbau von getrennten Steuergeräten sinnvoll erscheint, können die Funktionen der Geschwindigkeitsregelanlage und des Steuergerätes für die antriebslosen Fahrbetriebsphasen auch in einem einzigen Steuergerät verwirklicht werden, das zusätzlich, wie eben auch die Geschwindigkeitsregelanlage, eine Steuerleitung zu einem Leistungsstellglied (Drosselklappe oder Einspritzpumpe) der Brennkraftmaschine aufweist und mit einem Schalter zur Aktivierung der Geschwindigkeitsregelfunktion in Verbindung steht.Although the installation of separate control units makes sense, the Functions of the speed control system and the control unit for the non-powered Fahrbetriebsphasen also realized in a single controller that, in addition, as well as the cruise control system, a control line to a power actuator (throttle or injection pump) the internal combustion engine and having a switch for activation the speed control function is in communication.
Zum besseren Verständnis der Erfindung ist der Beschreibung eine Zeichnung beigefügt, in der der erfindungsgemäße Antriebsstrang samt notwendigen Steuergeräten schematisch dargestellt ist.To the better understanding The invention is the description of a drawing attached, in which Drive train according to the invention including necessary control units is shown schematically.

in Kombination mit der Geschwindigkeitsregelfunktion erfolgt so,
dass die durch den Fahrer des Kraftfahrzeuges aktivierte Geschwindigkeitsregelfunktion

von dem Steuergerät
Grundsätzlich abgeschaltet
wird die Geschwindigkeitsregelanlage
Wenngleich
die Geschwindigkeitsregelanlage
Die
hier vorgestellte Integrierung einer Geschwindigkeitsregelanlage
in einen Antriebsstrang eines Kraftfahrzeuges, mit dem antriebslose
Fahrtriebsphasen ermöglicht
werden können,
erlaubt einen besonders vorteilhaften und komfortablen Betrieb eines
derartigen Fahrzeuges. Wenn beide Steuergeräte aktiviert sind, kann in
einer Antriebsphase in der Geschwindigkeitsregelanlage durch entsprechende
Auslenkung des Fahrpedals und Betätigen des Schalters
Dieses
Zusammenwirken der Steuergeräte
Dadurch wird etwa bei Fahrten am Berghang ein sicherer Motorbremsbetrieb möglich, da auch die Geschwindigkeitsregelanlage, wie aus dem beschriebenen Stand der Technik bekannt ist, eine weitere Geschwindigkeitszunahme unterbindet.Thereby For example, when driving on the mountainside, a safe engine braking operation possible, as well as the cruise control system, as described from the State of the art is known, a further increase in speed in derogation.
