摘要
The invention relates to a steering angle sensor system with enhanced redundancy in order to increase faultlessness in measured results. In order to meet the safety requirements of steer by wire or other vehicle adjustment systems with regard to steering angle measurement data, several sensors (3, 4, 12) are operated in parallel and measurement data provided by a second fault-free sensor is evaluated if a first sensor is found to be faulty. Advantageous embodiments of the invention involve allocation of several sensor heads to a code track, the use of various physical measurement procedures within the same sensor system and the use of said sensors with a varying degree of measurement accuracy.
