Abstract: The disclosure relates to a method of determining the initialization state of a multi-turn sensor based on the sensor outputs. The method takes a reading of the sensor outputs, and then determines whether the sensor outputs are feasible based on an assumption that the sensor is initialised in one of two states. If the sensor outputs are correct, this initial assumption is taken to also be correct. However, if an incorrect sensor output is read, then it is taken that the assumed initialization state is incorrect. The sensor is therefore taken to be initialised in the alternative state. The method will then determine whether the sensor outputs are feasible based on this second assumption, and if an incorrect sensor output is still being read, then there is a fault in the multi-turn sensor.

Abstract: Aspects of the present disclosure relate to decoding the output of a multi-turn magnetic sensor using a successive approximation technique to detect a number of turns of a magnetic target. A decoder circuit can decode a turn count of the multi-turn magnetic sensor by obtaining measurements at nodes that are determined from values of previous measurements.
