CPJazz – A Software Framework for Vehicle Systems Integration and Wireless Connectivity

Integration of new technology into vehicles continues at a rapid pace. New technology includes not only deeply embedded devices for vehicle systems management but also operator interfaces such as navigation systems, voice-recognition/text-to-speech interfaces and integration of consumer electronic appliances such as the Personal Digital Assistant (PDA). Standardization efforts have attempted to bring these technologies together through common buses, but because these devices have different capabilities and requirements of their own this is most likely impossible. The CPJazz framework was designed to provide integration of disparate devices and protocols through a dynamic and scalable component-like architecture. In this paper the capabilities and services provided by CPJazz for vehicle-based software integrators will be discussed as well as the identification of key scenarios that demonstrate its contributions to the vehicle and wireless environment.
