  • the present invention relates to a method for starting in a multiple clutch transmission, in particular in a double clutch transmission, according to the preamble of claim 1.
  • Double clutch transmissions are known from vehicle technology. Such transmissions usually comprise essentially two sub-transmissions with different pairs of gears, a double clutch with two friction clutches, an input shaft and an output shaft and, depending on the number of gears, form-fitting, unsynchronized clutches.
  • a dual clutch transmission the gears can be shifted without load and without interruption of tractive power and without tensioning the shiftable gears, since the next gear to be shifted is already engaged in the non-coupled sub-transmission.
  • one friction clutch is opened and the second is closed accordingly.
  • the three and multiple clutch transmissions are generally based on the same principle.
  • one of the friction clutches synchronizes the drive motor or the drive to the output speed in such a way that the motor is not stalled.
  • both couplings are dimensioned accordingly large, since the thermal load occurring here is very large.
  • DE 100 15 296 AI discloses a double clutch transmission, in which the two clutches are partially closed when starting.
  • the clutch torque of the first clutch is continuously increased during the start, the clutch torque of the second clutch running towards zero. Only when starting in first gear, both clutches are partially closed, the torque support of the second gear becoming less and less during starting and thus the thermal load on the first clutch increasing more and more. The thermal load is thus only partially reduced.
  • the present invention has for its object to provide a method for starting for a multiple clutch transmission, in particular a double clutch transmission, which makes it possible to reduce the thermal load on the starting clutches.
  • the starting clutches can be designed to be smaller in terms of their thermal load-bearing capacity, which also results in a reduction in costs.
  • the starting clutches when starting with a multiple clutch transmission.
  • a sub-transmission can be engaged, so that the thermal load when starting is distributed over at least two clutches.
  • the at least two clutches used are constant during the start-up over the entire start-up period. Torque partially closed. It is only shortly before the differential speed in the clutch of the first gear approaches zero that it is opened. The torque reduction in the clutch of the first gear is from
  • Second gear clutch adopted so that the total drive torque remains constant. The best possible acceleration process is thus achieved.
  • the final gear of this acceleration process results from the accelerator pedal position and the respective driving resistance. Only when the driving resistance is so great that the driving performance only corresponds to the driving resistance in first gear, does the starting process end in first gear and the clutch in second gear is no longer engaged.
  • the torque at the gearbox output thus results from the sum of the clutch torques of the at least two starting clutches with the gear ratios generated in each case in the at least two sub-gearboxes.
  • both starting clutches are used simultaneously during the starting process.
  • a sensible extension of the start-up process is that the drive motor is included in the control process.
  • the drive motor should only start up from its idling speed up to a low speed, e.g. B. 1 200 U / min, with the highest possible torque.
  • the drive motor is held until the slipping process in the clutches is completed, that is, until the clutch of the second gear is completely closed.
  • the drive motor is, and thus the Antriebsmas' chine up to its rated speed, z. B. 1 900 U / min accelerated.

  • the first gear can be engaged in the first sub-transmission 5 and the second gear in the second sub-transmission 5 ';
  • the starting process can be carried out with both clutches 4, 4 '.
  • the torque at the transmission output results from the sum of the clutch torque of the clutch 4 assigned to the first sub-transmission 5 with the translation of the first gear and the clutch torque of the clutch 4 'assigned to the second sub-transmission 5' with the translation of the second gear. In this way, the required friction work can be distributed to both clutches 4, 4 '.
  • the differential speed in clutch 4 assigned to first partial transmission 5 will first strive towards zero. Shortly before this state is reached, this clutch 4 is fully opened and the vehicle is only further accelerated with the clutch 4 'assigned to the second partial transmission 5'. nigt. At the same time, the transmission 5 shifts from first to third gear. When this switching process is complete, the clutch 4 begins to close again and thus supports the clutch 4 '.
  • the procedure can be continued analogously for the shift into fourth gear; depending on the respective conditions, it may be appropriate to carry out the method until the clutch 4 is opened for the first time.

  • the method can also be applied analogously to multiple clutch transmissions.
  • the friction work can be distributed over the three clutches.

Abstract

L'invention concerne un procédé de démarrage pour une transmission à plusieurs embrayages, notamment une transmission à double embrayage, qui comprend un arbre d'entrée, un arbre de sortie, au moins deux embrayages de démarrage et au moins deux transmissions partielles qui génèrent différentes vitesses, un embrayage de démarrage étant affecté à chaque transmission partielle. Le procédé selon l'invention est caractérisé en ce qu'on utilise au moins deux embrayages de démarrage (4, 4') pour le démarrage, en ce qu'une vitesse est enclenchée dans chaque transmission partielle (5, 5') couplable au moyen de ces deux embrayages de démarrage (4, 4') de sorte que la charge thermique lors du démarrage se répartit sur au moins deux embrayages (4, 4'), et en ce que le moment de rotation au niveau de la sortie de transmission est égal à la somme des moments d'embrayage des deux embrayages de démarrage (4, 4') et des démultiplications de vitesse générées respectivement dans les transmissions partielles (5, 5').
