ABSTRACT:
A calibration method for calibrating a compass system suitable for use in a vehicle includes sampling data points of a magnetic field with a magneto-responsive sensor and processing output signals of the sensor via compass circuitry. The compass circuitry includes an analog-to-digital converter for converting analog signals of the sensor to digital signals and a digital-to-analog converter for converting digital signals to analog signals that are supplied to the sensor for adjusting the sensor. The output signals of the sensor are adjusted to be within an operable range of an analog-to-digital converter via an initial calibration mode. After completion of the initial calibration mode, output signals of the sensor are processed to determine when the output signals are outside a range of the analog-to-digital converter. An output of a digital-to-analog converter is adjusted to reposition the output signals of the sensor to be within the range of the analog-to-digital converter.
