Auto-calibration of acceleration sensors

摘要

Representative implementations of devices and techniques provide calibration for a sensor. The calibration includes adapting an output signal of the sensor based on acceleration components at the sensor and a rotational frequency of the sensor.

1. A method of calibrating a sensor, comprising:
receiving an output signal of the sensor, the output signal comprising one or more acceleration components acting at the sensor; receiving a rotational frequency of the sensor; calculating an acceleration component due to a centrifugal force acting at the sensor, based on the rotational frequency of the sensor; computing a radial acceleration of the sensor and adapting the output signal of the sensor based on the computation; and calibrating the sensor based on the output signal of the sensor and the calculated acceleration component due to the centrifugal force.
