ABSTRACT:
An electric servo steering arrangement and method for motor vehicles with a rotational angle sensor configuration for acquisition of the position of the steering movement has a support plate rotating relative or corresponding to the steering movement, with at least one code track and at least one stationary sensor acting on the code track. The code track is disposed about the rotational axis of the support plate and has markings for generating a sequentially changing bit pattern and the 360° of the circumference divided by the number of markings on the circumference defines a clock angle (β). The bit pattern is determined by a phase-shifted disposition of markings with respect to the fixed division of the clock angle (β).
