Industry efforts to standardize the car bus

The ever increasing complexity of automotive entertainment and information systems has necessitated a universal communication network for vehicles. Intelligent transportation systems (ITS) initiatives have focused on road and rail infrastructure, to enable telematics communications between roadway/railway, vehicles and public agencies, primarily to provide enhanced public services, such as traffic management and emergency response. While the development of infrastructure standards has been largely backed by national governments, standards for an in-vehicle bus platform to support both these enhanced services and the connectivity of consumer electronics (CE) devices have been left to the commercial market to develop. This paper discusses the standardization activities for such a network.
