Zusammenfassung:	The present disclosure relates to a method for operating a vehicle based on wheel torque. According to a first aspect, this disclosure proposes a method for operating a vehicle comprising a drivetrain. The method comprises determining S2, based on angular positions of one or more shafts of the drivetrain at different points along the drivetrain, a windup of the one or more shafts. The method further comprises estimating S3 a wheel torque of one or more wheels arranged on a driven wheel axle 11 of the vehicle based on the determined windup and a stiffness constant representing characteristics of the one or more shafts 11a,11b in-between the different points and using S7 the estimated wheel torque while operating the vehicle. The disclosure also relates to corresponding sensor arrangement 200 and computer program, and to a vehicle comprising the sensor arrangement.
