Abstract
A method implements a starting process for an internal combustion engine which has a drive unit and a transmission with at least two transmission input shafts and a multiple clutch device, in particular a double clutch device. During the starting process, the first gear is engaged in a first clutch of the multiple clutch device and is activated, while the second gear speed is engaged in a second clutch of the multiple clutch device but not activated. During the starting process, a current velocity is compared with a predefinable reference velocity, and when the reference velocity is reached a control unit causes the first clutch to be opened and thus causes the first gear to be deactivated while, in parallel with this, the second clutch is closed and the second gear is thus activated.
