    • A vehicle compass system for compensating for magnetic disturbances caused by a moveable vehicle accessory includes a magnetic field sensor and a control circuit coupled to the moveable vehicle accessory and the magnetic field sensor. The magnetic field sensor is positioned at a distance from the moveable vehicle accessory and is configured to determine an orientation of the magnetic field sensor with respect to the Earth's magnetic field and to generate magnetic field data. The control circuit is configured to receive a position signal from the moveable vehicle accessory indicating whether the moveable vehicle accessory is changing position, to receive magnetic field data from the magnetic field sensor, to compare first magnetic field data generated prior to the change in position of the moveable vehicle accessory to second magnetic field data generated after the change in position of the moveable vehicle accessory and to generate a correction value based on the comparison of the first magnetic field data and the second magnetic field data. The correction value is used to correct for the magnetic disturbance caused by the moveable vehicle accessory.
    • 用于补偿由可移动车辆附件引起的磁干扰的车辆罗盘系统包括磁场传感器和耦合到可移动车辆附件和磁场传感器的控制电路。 磁场传感器被定位在距可移动车辆附件一定距离处并且被配置为确定磁场传感器相对于地球磁场的方位并且生成磁场数据。 控制电路被配置为从可移动交通工具附件接收指示可移动交通工具附件是否正在改变位置的位置信号,从磁场传感器接收磁场数据,比较在位置改变之前生成的第一磁场数据 所述可移动车辆附件用于在所述可移动车辆附件的位置改变之后生成的第二磁场数据并且基于所述第一磁场数据与所述第二磁场数据的比较生成校正值。 校正值用于校正由可移动车辆附件引起的磁干扰。
