A car body control system based on CAN/LIN-bus technology

Based on some analysis of car bus in car control field, this paper puts forward making use of a CAN/LIN bus to control car body methods, by means of the mixed bus technology, we have designed a car body control system, which consist of a mixed network frame and an intelligence master control node. In car body control system, similar control systems have only CAN bus application, UN bus is at primary development period, CAN/LIN mixed bus is a new application. Some key problems in control system design like network scheme working principle and UN application are discussed; some methods to solve them are also put forward. The UN bus application reduces the manifold of existing low-end SCI based multiplex solutions and cuts the cost of development, production, service, and logistics in vehicle electronics.
