Abstract
A torque sensor unit measures torque introduced into an upper steering shaft of a motor vehicle. The upper steering shaft can be connected to a lower steering shaft via a torsion bar. The torque sensor unit may have two inductive sensors, where a first inductive sensor can be connected to the upper steering shaft to measure the rotary position of the upper steering shaft and a second inductive sensor can be connected to the lower steering shaft to measure the rotary position of the lower steering shaft. An evaluation unit may be designed to process the signals of the two inductive sensors and to calculate the torque therefrom by means of the angle difference between the rotary positions of the two steering shafts.
