The automobile currently has a number of processors to control different subsystems such as engine controller, transmission controller, ABS controller, lighting controller, entertainment controller, and airbag controller. These subsystems are connected as a single vehicle network. Different vehicle networks can run under different protocols such as CAN, VAN, SCP, DLC, ACP, and J1939. Controller Area Network (CAN) has become the standard for the automotive industry. However, CAN has limited speed to incorporate new applications, such as invehicle multimedia, entertainment, navigation, and computing. A new technology, Media Oriented Systems Transport (MOST), provides high bandwidth to accommodate such applications. Moreover, a trend exists to include other functionality, such as access to information in the car through wireless technology to provide Internet access that enables remote diagnostics, status update, roadside assistance, navigation, global positioning, infotainment, traffic monitoring, emergency, safety, and security service. A system architecture approach to integrate CAN, MOST and wireless communication system into the car environment has been presented in this paper. Moreover, an open and universally accessible architecture of a Car Intranet infrastructure that includes three network technologies CAN, MOST, and Wireless communication has been proposed. This infrastructure can provide an entirely new type of service in addition to current services can be delivered to cars in an efficient and secure way through wireless data connectivity over the Internet.
