Abstract

Systems and methods for detecting magnetic turn counter errors are provided herein. In one aspect, there is provided a magnetic field turn sensor system including: a magnetic field angle sensor, a signal processing path configured to receive an output from the magnetic field angle sensor and generate an angle measurement based on the output, a turn count path configured to process the output from the magnetic field angle sensor and output a quadrant measurement based on the output and a processor. The processor is configured to: receive the angle measurement from the signal processing path and the quadrant measurement from the turn count path, determine that the angle measurement deviates from the expected transition angle by more than a threshold value, and indicate a fault in response to determining that the angle measurement deviates from the expected transition angle by more than the threshold value.
