Abstract: A method of acquiring vehicle data from a vehicle data bus is disclosed. The method is responsive to the execution of a telematics application on a local telematics unit. The method comprises first accessing a local vehicle library, in response to vehicle data requests from the application. The local vehicle library then carries out steps comprising: retrieving vehicle data bus information from a database; using the vehicle data bus information to extract vehicle data from the vehicle data bus, the vehicle data corresponding to the requests for vehicle parameter data; interpreting the retrieved vehicle data; and providing the interpreted data to the telematics application to satisfy the request for vehicle data.

Abstract: A vehicle diagnostic and prognostic system and method is disclosed. The preferred system operates from a centralized processor-based data network system and also includes a vehicle interface architecture subsystem, a vehicle configuration information subsystem, an applications engine, and a presentation subsystem. More specifically, the vehicle interface architecture subsystem is adapted for retrieving operational data and identification data from a vehicle and the vehicle configuration information subsystem is adapted for providing vehicle configuration data, vehicle variant data and/or driving style related data to the diagnostic and prognostic system. Both of these subsystems are also coupled to the applications engine that is adapted for analysing the various data, identifying trends and making an overall diagnosis or prognosis.
