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.
Claims21
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 respective clutch to an engine, wherein after recognition of a desire to shift, a first clutch from said respective clutches, assigned to the transmission input shaft that is transmitting the torque, is disengaged up to a slip limit and an engine torque(Teng) is driven as a function of a type of shifting in order to achieve a vehicle acceleration desired by a driver, wherein a torque (Temotor) of an electric motor is used as an additional torque.
