A method for operating a rotation angle sensor unit for steering systems of motor vehicles, wherein the rotation angle sensor unit has an intermeshing gearwheel pair, wherein a first gearwheel is provided to be connected to the steering component for conjoint rotation and a second gearwheel is mounted in a rotationally fixed manner with respect to the first gearwheel, wherein two first and two second rotation angle sensors are assigned to the first and second gearwheels respectively, and the rotation angle sensor unit comprises a control unit with two independent control units, wherein, for operation of the rotation angle sensor unit with the predetermined vehicle safety integrity level, at the time of initialization of the rotation angle sensor unit each controller unit determines an initial absolute rotation angle for the steering component, and the initial absolute rotation angles are initially synchronized once, wherein each controller unit after initial synchronization continuously determines a first and second absolute rotation angle of the steering component from rotation angle data of a first rotation angle sensor on the one hand and from rotation angle data of a second rotation angle sensor on the other hand and combines these in a plausibilized manner to form an absolute rotation angle.
