Claim 11:
12. A telematics device comprising:
at least one processor operable to:
transmit a plurality of requests for fuel data to a plurality of fuel data sources of a vehicle via at least one vehicle interface during a trip completed by the vehicle, each fuel data source in the plurality of fuel data sources corresponding to at least one internal sensor of the vehicle;
receive, in response to the plurality of requests, the fuel data requested from the each fuel data source via the at least one vehicle interface;
track, during the trip, for the each fuel data source, a cumulative amount of fuel consumed by the vehicle determined based on the fuel data requested and received from the each fuel data source and the at least one internal sensor corresponding to the each fuel data source;
determine a confidence level of the each fuel data source in the plurality of fuel data sources at a plurality of points in the trip based on the fuel data a correlation between the cumulative amount of fuel consumed by the vehicle and an additional property of the vehicle measured by the at least one processor via the at least one vehicle interface;
identify an initial fuel data source from the plurality of fuel data sources;
generate a plurality of mid-trip fuel records, each mid-trip fuel record indicating the cumulative amount of fuel consumed by the vehicle at a point in the trip determined based on the fuel data requested and received from the initial fuel data source;
identify a final fuel data source from the plurality of fuel data sources based on a priority of the each fuel data source and the confidence level of the each fuel data source;
determine whether the plurality of mid-trip fuel records is valid based on whether the initial fuel data source is a same fuel data source as the final fuel data source; and
transmit the plurality of mid-trip fuel records and an indication of whether the plurality of mid-trip fuel records is valid to a fleet management system.
