TWIN-CLUTCH GEARBOX AND METHOD FOR SHIFTING AN INITIAL GEAR UPWARDS INTO A TARGET GEAR IN THE TWIN-CLUTCH GEARBOX OF A MOTOR VEHICLE

Document Type and Number:

WIPO Patent Application WO2003074313

Kind Code:

A3

Abstract:

The invention relates to a method for shifting an initial gear upwards into a target gear in a twin-clutch gearbox of a motor vehicle. According to the invention, the engine torque (MMot) of the vehicle is altered when a target gear is selected incorrectly and detected thus. The output torque (MAbtrieb) is then reduced if the correct target gear is introduced. The invention also relates to a twin-clutch gearbox, especially for carrying out said method.
