Description
Die Erfindung betrifft eine Steuerungseinrichtung zur Steuerung des Motorbremsbetriebes eines Kraftfahrzeuges gemäß dem Oberbegriff des Patentanspruchs 1, bei der in sogenannten Schubbetriebsphasen oder Schwungnutzphasen die Brennkraftmaschine vom Antriebsstrang abgekoppelt und stillgesetzt wird.The The invention relates to a control device for controlling the Engine braking operation of a motor vehicle according to the preamble of the claim 1, in the so-called push operation phases or swing useful phases the engine disconnected from the drive train and stopped becomes.
Aus
der deutschen Patentanmeldung
Zudem ist aus der Zeitschrift mot Auto Technik Zukunft Nr. 23, 1992 Seite 152 bekannt, daß sich die Brennkraftmaschine zur Durchführung eines Motorbremsbetriebes mittels einer Taste an einem Schaltstock des Kraftfahrzeuges manuell starten und in den Antriebsstrang einkuppeln läßt. Dieser im Hinblick auf den Kraftstoffverbrauch und das Emissionsverhalten des Kraftfahrzeuges ungünstigere Betriebsfall wird von dem Fahrer eines derartigen Kraftfahrzeuges in der Regel dann gewünscht, wenn beispielsweise bei Bergabfahrten durch die Bremswirkung der eingekuppelten Brennkraftmaschine die Radbremsen des Kraftfahrzeuges geschont werden sollen.moreover is from the magazine mot Auto Technik Future No. 23, 1992 page 152 announced that the Internal combustion engine for implementation an engine braking operation by means of a button on a shift stick Start the motor vehicle manually and engage in the drive train leaves. This in terms of fuel consumption and emission behavior of the motor vehicle unfavorable Operating case is the driver of such a motor vehicle usually then desired if, for example, when driving downhill due to the braking effect of Engaged internal combustion engine, the wheel brakes of the motor vehicle should be spared.
Die ansich vorteilhafte Freilauffunktion von Fahrzeugen mit der aus dieser Zeitschrift bekannten "Schwungnutz-Automatik" wirkt sich aber bei einigen Betriebssituationen nachteilig auf die Fahreigenschaften des Kraftfahrzeuges aus. Insbesondere beim Bremsen in sich engerziehenden Kurven, wie z. B. bei Autobahn-Ausfahrten, neigen derartige Fahrzeuge insbesondere bei ungeübten Fahrern dazu, wegen der fehlenden und sonst die Fahrzeugverzögerung unterstützenden Motorbremswirkung ungewohnt langsam zu verzögern. Da in derartigen Fahrsituationen der Kraftfahrer seine Aufmerksamkeit verstärkt den Straßen- und Umgebungsverhältnissen widmet, ist eine Aktivierung und Einkupplung der Brennkraftmaschine über einen manuell zu betätigenden Schalter unvorteilhaft.The ansich advantageous freewheeling function of vehicles with the However, this magazine known "momentum automatic" affects but in some operating situations disadvantageous to the driving characteristics of the motor vehicle. Especially when braking in a tightening Curves, such. As in highway exits tend such vehicles especially in the untrained Drivers to, because of the missing and otherwise the vehicle deceleration supportive Engine braking effect unusually slow to retard. Because in such driving situations the driver focuses his attention on the road and surrounding conditions, is an activation and engagement of the internal combustion engine via a manually operated Switch unfavorable.

Außerdem ist
aus der Patentanmeldung
Bei
der Patentanmeldung
Da das erneute Auskuppeln der Brennkraftmaschine in bestimmten Fahrsituationen, wie z. B. beim Durchfahren einer letzten Bergab-Serpentinenkurve kurz vor der nächsten Bergauf-Serpentinenkurve, als unkomfortabel befunden wird, wird als Aufgabe der Erfindung angesehen, die bekannte Steuerungseinrichtung derart weiterzubilden, daß z. B. bei Bergfahrten oder in Kurvenfahrten die Umschalthäufigkeit hin zur antriebslosen Schubbetriebsphase Fahrkomfort erhöhend reduziert wird.There the renewed disengagement of the internal combustion engine in certain driving situations, such as B. when driving through a last downhill serpentine curve just before the next Uphill serpentine curve is found to be uncomfortable is the object of the invention considered to develop the known control device such that z. B. when driving uphill or in turns the Umschalthäufigkeit Towards the drive-less overrun phase, driving comfort is reduced becomes.
Die Lösung dieser Aufgabe ergibt sich aus den Merkmalen des Anspruchs 1, während Unteranspruch 2 eine vorteilhafte Ausgestaltung der Erfindung beinhaltet. Demnach wird gemäß Anspruch 1 der Motorbremsbetrieb auch bei nicht aktivierter Bremse so lange aufrecht erhalten, bis der Fahrer durch derart starke Auslenkung des Fahrpedals den Motorbremsbetrieb beendet, mit der bei der gerade vorliegenden Fahrgeschwindigkeit und dem gewählten Gang mindestens ein erneuter Zugbetrieb des Fahrzeugs möglich ist. Ein erneuter antriebsloser Schubbetrieb des Fahrzeuges, eingeleitet durch Öffnen der Kupplung zwischen der Brennkraftmaschine und dem Getriebe, wird nach einem Motorbremsbetrieb erst nach dieser erneuten Zugbetriebsphase möglich.The solution of this problem arises from the features of claim 1, while subclaim 2 includes an advantageous embodiment of the invention. Accordingly, according to claim 1, the engine braking operation is maintained even when the brake is not activated until the driver stops by such strong deflection of the accelerator pedal engine braking operation, with the at the present driving speed and the selected gear at least one renewed train operation of the vehicle is possible. A renewed unpowered overrun operation of the vehicle, initiated by opening the clutch between the internal combustion engine and the transmission, after an engine braking operation only after this renewed Zugbetriebsphase possible.
Wie Anspruch 2 entnehmbar ist, wird in Ausgestaltung der Erfindung die Kupplung zwischen der Brennkraftmaschine und dem Getriebe in der Phase des Motorbremsbetriebes dann kurzzeitig geöffnet und anschließend erneut geschlossen, wenn ein Getriebeschaltvorgang erfolgen soll.As Claim 2 can be removed is in an embodiment of the invention the Clutch between the engine and the transmission in the Phase of the engine braking operation then briefly open and then again closed when a gear shift operation is to take place.
