摘要:
The invention relates to measures for controlling or reducing drag torque occurring in a multi-plate clutch device (202) due to temperature-related increased viscosity of an operating fluid which is supplied to the plates in operation. The aim of the invention is to enable a motor vehicle to be started or operated even at low temperatures. According to one aspect of the invention, a motor vehicle comprising a drive train is especially provided. Said drive train comprises a drive unit (238), a gearbox (330) having a first gearbox input shaft and a second gearbox input shaft, and a clutch (202) 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. Said clutch devices are embodied in the form of plate clutches to which an operating fluid can be supplied, especially a cooling oil, in order to operate the same. Said gearbox (330) is associated with an actuator device and a control device (316) 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. According to the invention, the control device (316) is designed in such a way that at least one gear is automatically engaged by means of the actuator device (236), as a result of the clutch release of the vehicle.
