DYNAMIC DATA COLLECTION FOR VEHICLE TRACKING
A telematics system comprises a sensor recording a plurality of operating parameters of a vehicle. A data hub coupled to the sensor receives the plurality of operating parameters from the sensor. The data hub comprises a buffer. The data hub transforms the plurality of operating parameters into a plurality of relative operating parameters. Each of the plurality of relative operating parameters comprises a change in one of the plurality of operating parameters since the previous one of the plurality of operating parameters. The data hub stores the plurality of relative operating parameters in the buffer. A wireless modem is coupled to the data hub. The wireless modem transmits the plurality of relative operating parameters to an external server. The data hub performs a fitting of the plurality of relative operating parameters to a shape, discarding any of the plurality of relative operating parameters that are not required.
