Method and device for rotary angle adaption at a rotation angle sensor of a DC motor

Method and device for rotary angle adaption at a rotation angle sensor of a DC motor Disclosed is a method for adaptation of rotational angle at a rotation angle sensor (DS) of a DC motor (GM), with the following steps: - determining (S100) a first normalized rotation angle (w1) which the DC motor (GM) in a first direction of rotation (DR1) for a unit time (t) under the action of a torque unit (M) has come; - determining (S300) a second normalized rotation angle (w2), to the dc motor (GM) in a second, the first direction of rotation (DR1) opposite rotational direction (DR2) for the same time unit (t) under the action of the same torque unit (M) has come; - calculating (S500) a difference in rotational angle (wd) between the first (w1) and second (w2) normalized angle of rotation; - comparing (S600) the difference in rotational angle (wd) at a predetermined rotational angle threshold (ws); - determining (S700) exceeds an adaptation angle (aw) when the rotation angle difference (wd) the rotation angle threshold (ws).
