Abstract

A motor vehicle includes a drive train having a drive unit, a gearbox having a first gearbox input shaft and a second gearbox input shaft, and a clutch having a first clutch device which is associated with the first gearbox input shaft, and a second clutch device which is associated with the second gearbox input shaft, for transferring torque between the drive unit and the gearbox. The first and second clutch devices are plate clutches to which an operating fluid, such as a cooling oil, is supplied to operate the same. The gearbox is associated with an actuator device and a control device for controlling the actuator device, the arrangement of which enables the gears associated with the first and second gearbox input shafts to be engaged and disengaged. The control device is designed such that at least one gear is automatically engaged by the actuator device, as a result of the clutch release of the vehicle.
