A steering column for a motor vehicle includes comprising a supporting unit which can be connected to the chassis of the motor vehicle and an actuating unit, which is mounted on the supporting unit and which supports a steering shaft for rotation. The position of the actuating unit can be adjusted in relation to the supporting unit and the steering column has a position detection device for determining the position of the actuating unit relative to the supporting unit.

A printed circuit board may include a top side, a bottom side, and a circumferential surface that connects the top side to the bottom side. The circumferential surface may have a toothing for forming a gear wheel. The toothing may be circumferentially closed and may be arranged over an entire surface area of the circumferential surface. The toothing may be configured as an involute toothing, an epicycloid toothing, a hypocycloid toothing, or a lantern gear toothing. The printed circuit board may be formed of fiber-reinforced plastic. Further, the printed circuit board may include a track, a surface structure, and/or a conductor track configured for inductive sampling, capacitive sampling, optical sampling, and/or acoustic sampling.

A device and a method may be used to determine a highly accurate absolute angle of rotation Xt of the rotational position of a rotatably supported steering shaft. Rotation of a rotor of an electric motor with a gearing with a gearing transmission factor K for power assistance may be coupled into rotation of the steering shaft. A rotational position of rotation of the rotor can be measured by means of a rotor position sensor and by using a number of revolutions of the rotor that have occurred. This value is used directly to determine the highly accurate absolute angle of rotation Xt of the steering shaft. Calibration methods involve determining initial values from which the counting of revolutions or the calculations occur.
