Abstract:
1. A transmission configuration, comprising: a drive shaft configured to be connected to a motor; an automated dual-clutch transmission including a housing and two transmission sections with respective input shafts, respective output shafts and respective motor clutches, said motor clutches having a motor side and a transmission side, and said motor clutches being connected to said drive shaft on the motor side of said motor clutches and being connected to a respective one of said input shafts on the transmission side of said motor clutches; an axle drive; each of said transmission sections including gearwheel sets, said gearwheel sets forming a respective group of gear stages and having respective fixed gears and respective idler gears; each of said transmission sections including gear clutches assigned to said idler gears such that, when a given one of said gear clutches assigned to a given one of said idler gears is engaged, a respective one of said input shafts is connected to a respective one of said output shafts with a given gear ratio, and said respective one of said output shafts is operatively connected to said axle drive; a drive-side speed sensor unit disposed at said drive shaft; an input-side speed sensor configuration including a first sensor wheel connected, fixed against relative rotation, to a first one of said input shafts, a second sensor wheel connected, fixed against relative rotation, to a second one of said input shafts, a first pulse sensor disposed stationary with respect to said housing and within an effective range of said first sensor wheel, and a second pulse sensor disposed stationary with respect to said housing and within an effective range of said second sensor wheel, said input-side speed sensor configuration being configured to detect a speed of said input shafts and a direction of rotation of at least one of said input shafts, said drive-side speed sensor unit and said input-side speed sensor configuration forming a sensor configuration for controlling said automated dual-clutch transmission; and said automated dual-clutch transmission being configured to complete a shift process with said input-side sensor configuration in the absence of an output-side speed sensor.
