摘要： An electronic compass is described for use in vehicles. The compass employs a magnetoresistive sensor for sensing the earth magnetic field and the sensor is operated in alternate set/reset bias modes. In a first embodiment, the compass is provided with deviation compensation by a closed loop system including measurement of the sensor output signals and an offset current strap for nullifying the vehicle deviation field. In a second embodiment, deviation compensation is provided by operation in an initial calibration mode and by operation in a normal calibration mode to adjust compensation, as needed, on a long term basis during normal operation of the compass. In the initial calibration mode, while the vehicle is being driven, the signal peak values are adjusted to a nominal earth field level by changing the offset current. Then, compensating signal reference values for each axis are determined as each peak for that axis is determined. The system automatically exits the initial calibration mode when certain criteria have been met. In the normal compensation mode, The signal reference value for each axis is adjusted at least once during the time interval between turn-on and turn-off of the vehicle ignition switch.

摘要： 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.

摘要： A compass compensation system is provided for automatically and continuously calibrating an electronic compass for a vehicle, without requiring an initial manual calibration or preset of the vehicle magnetic signature. The system initially adjusts a two axis sensor of the compass in response to a sampling of at least one initial data point. The system further calibrates the compass by sampling data points that are substantially opposite to one another on a plot of a magnetic field and averaging an ordinate of the data points to determine a respective zero value for the Earth magnetic field. The system also identifies a change in magnetic signature and adjusts the sensor assembly.
