A transmission configuration includes an automated dual-clutch transmission having two transmission sections with respective input shafts, respective output shafts and respective motor clutches. The motor clutches are connected, on a motor side thereof, to a drive shaft and to a respective one of the input shafts on a transmission side thereof. A drive-side speed sensor unit is disposed at the drive shaft. An input-side speed sensor configuration includes sensor wheels connected, fixed against relative rotation, to respective ones of the input shafts, and pulse sensors disposed stationary with respect to a housing and within an effective range of the respective sensor wheels. The input-side speed sensor configuration is configured to detect a speed of the input shafts and a direction of rotation of at least one of the input shafts. A method for controlling an automated dual-clutch transmission is also provided.

Transmission configuration and method for controlling a transmission

A twin clutch, in particular an actively closing, dry friction twin clutch is provided for a twin clutch transmission of a motor vehicle having an internal combustion engine, a crankshaft, and two transmission input shafts. The two transmission input shafts are connected to respective friction clutches and can be selectively connected to the crankshaft. At least one axial bearing is provided at the twin clutch such that axial forces, which are present when the clutch is actuated, can be transferred to the transmission housing.

Twin clutch

A twin-clutch transmission having the driving gear wheels of adjacent gears on different transmission input shafts permits skipping one gear stage while shifting gears, i.e. shifting between gears whose driving gear wheels are on the same transmission input shaft, by using an auxiliary gear on the other transmission input shaft to supply a filler torque while shifting between the initial gear and a selected gear.
