The acceleration of a mobile asset is sensed and compared to threshold acceleration levels when the speed of the mobile asset is above a threshold speed. When the acceleration exceeds a threshold a report is created allowing aggressive driving behavior to be logged.

Monitoring aggressive driving operation of a mobile asset

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.

An accelerometer sensor equipped device uses GPS and known alignment data to determine the alignment of the accelerometer sub-system when the vehicle is stationary and in motion. The alignment data is determined from known surface information, measured GPS velocity, and measured GPS Heading.
