Abstract:
1. 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, comprising: a first eddy current damping rotor being disposed on an end of an input shaft of a steering column divided by a torsion element; a second eddy current 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 said steering column passes at a right angle, said at least one carrier being fitted with flat coils extending throughout said angle range of 360 degrees; and at least one passive actuating element, without periodically repeated structures, being borne on each of said first and second eddy current damping rotors and positioned within a periphery of said at least one carrier and coils thereof, said actuating elements being in two different locations of said angle range and acting on said flat coils of said at least one carrier.
