A method, computer program and apparatus for determining the steering angle of a vehicle steering system

The invention relates to a method for determining the steering angle of a vehicle steering system. In this a coding element (14) having a steering shaft (12) is connected. The coding element (14) comprises a code track (16) detected in a code of the code track (16) during operation stationary sensor (22, 24, 26) is moved past. the steering shaft (12) for contactless determination, in which 360 DEG ° revolution precisely, the invention proposes that at least two in the direction of movement of the coding element (14) arranged one after the sensors (22, 24, 26) the code (18, 20) the code track (16) corresponding to different signal states (36, 38, 40) are taking. From the initial signal states (36, 38, 40) of the three sensors (22, 24, 26) and the change of the signal state (36, 38, 40) at least one sensor (20, 24, 26) determines the direction of rotation. The number of changes of the signal states (36, 38, 40) with the respective direction of rotation corresponding sign, starting from an initial value, added up and determines the rotation of the steering shaft (12) from the sum result.
