Abstract
The invention relates to a method for carrying out gear shifting in a twin-clutch gearbox comprising at least two gearbox input shafts which are respectively coupled to the engine by means of a clutch. According to the invention, after recognizing a desire to change gear, the clutch associated with the active torque transmitting gearbox input shaft is opened until the slip limit is reached and the engine torque is controlled according to the type of shifting in order to achieve the vehicle acceleration desired by the driver.
Claims22
A method for carrying out gear shifting in a twin-clutch transmission having at least two transmission input shafts, each of which is coupled via a clutch to the engine, wherein after recognition of a desire to shift, the clutch assigned to the transmission input shaft that is transmitting the torque is disengaged up to the slip limit and the engine torque (Teng) is driven as a function of the type of shifting in order to achieve a vehicle acceleration desired by the driver.
