Abstract:
1. A method for carrying out a starting process for a vehicle containing an internal combustion engine having a drive unit and a transmission with at least two transmission input shafts and one multiple clutch device, which comprises the steps of: engaging and activating a first gear with a first clutch of the multiple clutch device if a starting process is detected; engaging but not activating a second gear with a second clutch device of the multiple clutch device; during the starting process, continuously comparing a reference value with a predefinable reference variable; and causing, via a control device, the first clutch to open and thus causing the first gear to become deactivated when the predefinable reference variable is reached and, in parallel, causing the second clutch and thus causing the second gear to become activated so that an overall torque of the clutches defined by a sum of torques of the first clutch and the second clutch acting on the internal combustion engine is approximately constant during a shifting process and is less than or equal to a current engine torque.
