Abstract
Data records transmitted from a plurality of vehicles are collected at a central data repository, where realtime or batch analysis and profiling can take place to facilitate vehicle fleet maintenance. Preferably, each data record includes data derived by synchronizing on-board diagnostic computer output and GPS 3-dimensional location data, correlated by time and tagged with vehicle identification information, and is forwarded to the central data repository via cellular Internet. The central data repository includes analysis and profiling routines to identify immediate operational problems on a given vehicle, e.g., engine overheating, as well as overall fleet operational behavior, i.e. which vehicles, drivers and routes lead, over time, to increased maintenance costs. As data is collected over time, the experience database becomes more and more valuable and enables the fleet manager to improve its fleet operational decisions, such as route scheduling, maintenance scheduling, vehicle purchasing, driver assignments, and the like.
