Abstract:
A method for performing transform calibration of an accelerometer of a telematics device during installation in a vehicle includes placing the device in the vehicle at an initial position having a known alignment with a given frame of reference of the vehicle, moving the telematics device from the initial position to a final installation position in the vehicle with a tri-axial rate gyroscope of the device concurrently tracking and integrating the angle changes to provide a set of coordinates of the final installation position, and transform calibrating the accelerometer of the device using the set of coordinates so as to leave the device installed at the final position with its accelerometer transform calibrated with respect to the given frame of reference.
