Claim:
1. An arrangement for estimating input torque of a dual-clutch transmission for a vehicle, the arrangement comprising the transmission, the transmission comprising an inner input shaft and an outer input shaft arranged concentrically with respect to the inner input shaft, a dual-clutch assembly for connecting the inner input shaft and the outer input shaft to an output shaft of an engine, a torque sensor arranged on the outer input shaft and connected to a transmission control unit the torque sensor being arranged to provide a measured torque value (Tm) during operation of the outer input shaft, and a transmission control unit arranged to providing an estimated torque value (Te) for the inner input shaft during operation of the inner input shaft, the transmission control unit being arranged to calibrate against the measured torque value (Tm) during operation of the outer input shaft.
