Sensor module, method of correction therefor, and mobile object including the sensor module
摘要：
A sensor module maintaining high detection accuracy. Correction data of a detected magnetic field is updated only in a case that a fluctuation band acquired from an output signal of an acceleration sensor is less than a threshold value and a difference between an azimuth angle acquired from an output signal of a terrestrial magnetism sensor and an inclination angle acquired from an output signal of acceleration sensor is less than the threshold value. Therefore, the correction data is updated only in a case that a magnetic field at a position of a mobile object is stably detected, and an accuracy of the correction data can be maintained.

传感器模块保持高检测精度。 检测磁场的校正数据仅在从加速度传感器的输出信号获取的波动频带小于阈值和从地磁传感器的输出信号获取的方位角和 从加速度传感器的输出信号获取的倾斜角度小于阈值。 因此，仅在稳定地检测移动体的位置的磁场的情况下才更新校正数据，能够维持校正数据的精度。
