Abstract
A combined steering angle and torque sensor that inductively and with eddy current damping generates two absolute angle measurement signals over an angle range of 360 degrees including a first damping rotor being disposed on an end of an input shaft of steering column divided by a torsion element; a second damping rotor being disposed on an end of an output shaft of the steering column; at least one carrier being fixed to a housing of the steering column and through which the steering column passes at a right angle, the at least one carrier being fitted with flat coils in a complete angle range; and at least one passive actuating element, without periodically repeated structures, being borne on each of said first and second damping rotors, the actuating elements being in two different locations of said angle range acting on the flat coils of the at least one carrier.
