Abstract

Load change impacts in a motor vehicle, especially as a result of abrupt changes in the position of the accelerator pedal, are prevented with the novel method. At least one dual clutch mechanism is provided between the drive engine and the gearbox. The gearbox has several selectable gear steps and the clutch is controlled in relation to the torque that is to be transmitted. The driving comfort is improved by controlling the clutch during the starting process of the motor vehicle and/or the gear steps are engaged during the starting process of the vehicle in such a way that the speed of rotation of the gear input shaft is lower than the idling speed of rotation of the engine.
