Document Type and Number:
WIPO Patent Application WO2003074906
Kind Code:
A3
Abstract:
The invention relates to a shifting strategy for a gearbox, especially for a twin-clutch gearbox of a motor vehicle, wherein a target gear is preselected on a non-torque-transmitting gearbox input shaft, the rotational speed (Nlps ily) of the non-torque-transmitting gearbox input shaft is increased during the preselection of a gear. The invention also relates to a gearbox, especially a twin-clutch gearbox for a motor vehicle comprising at least two gearbox input shafts which are respectively associated with a clutch, especially for carrying out the shifting strategy. Said twin-clutch gearbox comprises at least one control device for increasing the rotational speed (Nlps ily) of the non-torque-transmitting gearbox input shaft during the preselection of a gear.
