A Framework for Information and Diagnostic Systems

Vehicle diagnostics and information systems have followed separate, parallel evolutionary paths. In addition, advances in hardware technology and software architecture are making possible new, integrated systems that provide a wide range of capabilities. These new capabilities require a significant software investment just to create the telematics infrastructure to support wireless access to the vehicle, new displays, or a different vehicle bus interface. This paper discusses the benefits of software architecture for the on-vehicle portion of such a telematics infrastructure, the key drivers for such architecture, and the benefits being realized as the architecture evolves.
