Abstract

The method involves using an electric motor for braking and/or accelerating a wheel set for supporting synchronizations. The electric motor is integrated into a moment strand of a transmission in a power flux direction toward a coupling, and is operated as a generator in an up-shifting phase. The wheel set is braked, and the electric motor is operated as an engine in a down-shifting phase of the electric motor. Force lacking with respect to switching impulse is complemented by the electric motor.

Description

Die vorliegende Erfindung bezieht sich auf ein Verfahren zur Schaltkomfortverbesserung bei einem Handschaltgetriebe eines Kraftfahrzeugs gemäß dem Oberbegriff des Patentanspruchs 1.The The present invention relates to a method of shifting comfort improvement in a manual transmission of a motor vehicle according to the Preamble of claim 1.

Bei Handschaltgetrieben wird der Synchronvorgang durch Ein- und Mehrfachsynchronisierungen vorgenommen. Hierbei gibt es zwischen dem Schaltimpuls, der an der Hand des Fahrers wirkt und dem Abstützmoment im Getriebe einen Zielkonflikt. Bei einem niedrigen Schaltimpuls, d. h. bei einer großen installierten Synchronleistung wird das Abstützmoment am Antriebsstrang größer. Dies wiederum resultiert darin, dass mehr Störungen, wie beispielsweise Schaltkratzen spürbar werden, da der Antriebsstrang sehr stark aufgezogen wird. Im umgekehrten Fall muss durch den Fahrer zu viel Kraft zum Synchronisieren aufgebracht werden, was den Komfort negativ beeinflusst.at Manual gearboxes, the synchronization process is performed by single and multiple synchronizations. Here there is between the switching pulse, the driver's hand acts and the support torque in the transmission a conflict of goals. At a low switching pulse, i. H. at a big one installed synchronous power becomes the support torque on Drivetrain larger. This in turn results in that more disturbances, such as scratching palpable because the powertrain is being pulled up a lot. In the reverse Case must be applied by the driver too much force to synchronize which negatively affects comfort.

Eine Schaltunterstützung an der Schiebemuffenbetätigung, beispielsweise an der Schaltwelle kann hier nur begrenzt helfen, da sich das durch die größere Schaltkraft ergebende höhere Abstützmoment ebenfalls durch Störungen bemerkbar macht.A Shift assistance on the sliding sleeve operation, For example, on the shift shaft can help only limited because this results from the greater switching power higher support torque also due to interference makes noticeable.

Aus der DE 4305054 A1 ist eine Antriebsvorrichtung für ein Elektromobil bekannt, bestehend aus einem mittels eines Stromrichters steuerbaren Elektromotor, aus einem Schaltgetriebe mit mindestens zwei Gängen, wobei den Gängen Kupplungen zugeordnet sind. Des weiteren umfasst die Antriebsvorrichtung einen Aktuator zum Einrücken der Kupplungen sowie eine Steuereinrichtung für den Schaltvorgang, der die Drehzahlen auf der Antriebsseite und auf der Abtriebsseite des Getriebes angebende Signale zugeführt sind.From the DE 4305054 A1 a drive device for a scooter is known, consisting of a controllable by a power converter electric motor, from a manual transmission with at least two gears, the gears are associated with clutches. Furthermore, the drive device comprises an actuator for engaging the clutches and a control device for the switching operation, which are fed to the speeds on the drive side and on the output side of the transmission indicating signals.

Hierbei sind die Kupplungen des Schaltgetriebes als Klauenkupplungen ohne mechanische Synchronisierung ausgebildet; die Steuereinrichtung wirkt einerseits auf den Aktuator mit Positionssensor und andererseits auf den den Elektromotor steuernden Stromrichter ein und stellt auf diese Weise den Gleichlauf der jeweiligen Kupplungshälften vor deren Hinrücken her.in this connection are the clutches of the gearbox as jaw clutches without mechanical synchronization formed; the control device acts on the one hand to the actuator with position sensor and on the other hand on the electric motor controlling the converter and provides in this way the synchronization of the respective coupling halves before approaching them.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Schaltkomfortverbesserung bei einem Handschaltgetriebe eines Kraftfahrzeugs anzugeben, durch dessen Durchführung die Synchronisierung ein niedriges Abstützmoment erfordert.Of the The present invention is based on the object, a method for shifting comfort in a manual transmission of a Motor vehicle, by its implementation, the synchronization requires a low support torque.

Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 gelöst. Weitere erfindungsgemäße Ausgestaltungen und Vorteile gehen aus den Unteransprüchen hervor.These The object is solved by the features of claim 1. Further embodiments and advantages of the invention are apparent from the dependent claims.

Demnach wird ein Verfahren zur Schaltkomfortverbesserung bei einem Handschaltgetriebe vorgeschlagen, im Rahmen dessen ein Elektromotor zum Bremsen oder Beschleunigen des Radsatzes zur Unterstützung der Synchronisierungen verwendet wird.Therefore is a method for shifting comfort in a manual transmission proposed, in the context of an electric motor for braking or Speed up the wheelset to support the syncs is used.

Gemäß der Erfindung wird ein Elektromotor, beispielsweise ein Startergenerator, der im Momentenstrang des Getriebes in Kraftflussrichtung nach der Kupplung integriert ist, in der Hochschaltphase als Generator betrieben und bremst somit den Radsatz ab. In der Runterschaltphase wird er als Motor betrieben, wodurch der Radsatz beschleunigt wird.According to the Invention is an electric motor, such as a starter generator, in the torque train of the transmission in the direction of power flow after the Coupling is integrated, operated in the upshift phase as a generator and thus slows down the wheelset. In the downshifting phase he will operated as a motor, whereby the wheelset is accelerated.

Durch die erfindungsgemäße Konzeption kann die Synchronisierung auf ein niedriges Abstützmoment optimiert werden, was in Schaltkomfortvorteilen bezüglich der Antriebsstrangreaktionen resultiert. Die bezüglich des Schaltimpulses fehlende Kraft wird erfindungsgemäß durch den Generator/Motor ergänzt.By the conception according to the invention can be the synchronization be optimized for a low support torque, resulting in Shift comfort advantages with respect to the powertrain reactions results. The missing force with respect to the switching pulse according to the invention supplemented by the generator / motor.
