摘要： A vehicle compass system including a magnetic field sensor from which the earth's magnetic field can be detected in two channels of measurement. The sensor is coupled to a processing circuit which samples the sensor data and determines the maximum and minimum signal levels in each channel of measurement during movement of the vehicle through a 360.degree. path of travel. Based on the spans between the maximum and minimum signal levels, adjustment signals are generated for adjusting the resolution of the compass system and the maximum and minimum signal levels of subsequent sensor data so that the system's sensitivity resolution may be adjusted and accurate heading information can be calculated and displayed regardless of the strength of the earth's magnetic field.

摘要： A vehicle compass system having a magnetic field sensor coupled to a processing circuit which samples the sensor data and implements a calibration routine that generates compensation signals to compensate the sensor for the effects of vehicular magnetism so that accurate heading information can be displayed on a display coupled to the processing circuit. If the signal levels detected are outside of a variable threshold, then the calibration routine is run. Also provided is a circuit for receiving vehicle position information in response to which the processing circuit adjusts the signals supplied to the display in order to account for magnetic variations between the true north and magnetic north.

摘要： The compass system of the present invention utilizes an improved calibration routine in which a processing circuit of the compass recalibrates the compass each time three data points are obtained from a magnetic field sensor that meet predetermined criteria. One such criterion is that the three data points define corners of a triangle that is substantially non-obtuse. When three data points have been obtained that define a triangle meeting this criterion, the processing circuit calculates a center point for a circle upon which all three data points lie by solving the equation x2+y2+Ax+By+C=0 for A, B, and C, using the coordinate values (x,y) for the three data points and defining the center point as (−A/2, −B/2).

摘要： An electronic compass system of the present invention includes a sensor for detecting the earth's magnetic field and for providing electrical signals representing the direction of the vehicle, a heading indicator for indicating vehicle headings in response to received vehicle heading signals, and a processor coupled to the sensor for receiving the electrical signals and coupled to the heading indicator for supplying the vehicle heading signals to the heading indicator. The processor preferably includes a first compass controller for calculating vehicle headings in response to the received electrical signals using precalibration data to compensate for expected vehicular magnetism, a second compass controller for calculating vehicle headings in response to the received electrical signals using an automatic calibration routine to compensate for actual vehicular magnetism, and a control transferring mechanism for initially selecting the vehicle headings calculated by the first compass controller to be represented by the vehicle heading signal supplied to the heading indicator, and for selecting the vehicle headings calculated by the second compass controller after the automatic calibration routine has acquired sufficient data from the magnetic field sensor to calibrate the compass system. The heading indicator may include a display and/or an audio messaging device for generating audible vehicle heading messages. If such an audible messaging device is employed, the device may also be used to record and playback dictated memos.
