Abstract
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.
