| In-vehicle network is among not only the most important productions in the information age, but also keys for the sustainable development of automotive technology. In overseas, its related research and development programs date from as far as early 1980's, during which time controller area network (CAN) was first brought forth to meet the increasing need for data exchange in future automobiles. Presently, there are many high-level practices in its application, and CAN is of the greatest market prospect. Late in 2001, China also launched research projects aiming to lay a foundation for the establishment of her own technical line and executive plan to develop in-vehicle network.Presented in the first part of this dissertation is the general situation of the In-vehicle network. The research fell into two sections: a survey on the status quo and future trend of automotive buses and communication protocols used overseas, which constitutes Chapter 2; and an analytic inquiry into CAN specification as well as its automotive application, which constitutes Chapter 3.Presented in the second part of this dissertation is the author's effort to introduce CAN into home-made automobiles. Some CAN nodes were worked out, and then a CAN based system was built up to adjust and control rear-view mirrors. |
