Abstract

A method for determining a steering angle offset (LWO) in a vehicle having a steering unit and a steering angle sensor. A first frequency distribution (HV1) of the steering angle (LW) is determined over a number of steering angles according to at least one dynamic vehicle parameter (Q, G, V), and the average value (MW1) of the steering angle (LW) is determined from the first frequency distribution (HV1). The next step tests whether the steering angle (LW) in the first frequency distribution (HV1) is distributed symmetrically around the average value (MW1) and, when there is symmetry of the first frequency distribution (HV1) around the average value (MW1), the first frequency distribution (HV1) is carried over into a second frequency distribution (HV2). When the overall number of steering angles (LW1) in the second frequency distribution (HV2) exceeds a prespecified threshold value (S), the steering angle offset (LWO) is determined from the average value (MW2) of the second frequency distribution (HV2). A device for determining a steering angle offset (LWO) in a vehicle by way of such a method is also described.
