Abstract
An arrangement for estimating the input torque of a dual-clutch transmission for a vehicle is provided. The transmission includes an inner input shaft and an outer input shaft arranged concentrically with respect to the inner input shaft. The arrangement further includes a dual-clutch assembly connecting the shafts to an output shaft of an engine. A torque sensor is arranged on the outer input shaft and connected to a transmission control unit. By torque sensor, a measured torque value is provided during operation of the outer input shaft and for providing an estimated torque value during operation of the inner input shaft.
