摘要

近年來，由於車輛上各項設備的電子化，以及線控系統的使用，促使車輛主系統對各車輛組件控制、訊號分享與訊息傳遞，因此車輛網路系統成為車輛電子控制系統的主要課題之ㄧ。
本論文針對CAN-Bus的通訊協定CAN2.0、ISO11898與節點架構進行探討，文中針對CAN控制器與CAN收發器進行規劃、分析與設計，藉以選定適當的CAN節點電路，並加以應用。
本研究採用Nissan Cefiro A32折疊式電動後視鏡，以及SAAB9-5八向電動座椅，並選用Atmel T89C51CC01與Philips ARM LPC2119，分別搭配Philips PCA82C251，構成電動後視鏡控制電路及電動座椅控制電路，並使用CAN-Bus對電動後視鏡以及電動座椅進行控制與資料回饋。實驗結果顯示，使用CAN節點進行電動後視鏡和電動座椅之控制，可符合新世代車身電子資訊通訊網路之需求。

CAN technology has expanded into all areas of automotive electronics application due to its high reliability and cost efficiency. Nowadays, CAN has become a standard for the implementation of data communication systems in vehicle. Hence, this paper presents an implementation of a CAN-based system with required microcontrollers to perform data communication.
Basically three parts are included in this article. The first part introduces the basic fundamentals and principles of the data link layer and physical layer of the CAN specification 2.0 and ISO11898(ISO11898-1,ISO11898-2), and the structure and functionality of CAN controller chips with integrated CAN module and transceiver chips currently offered on the market.
The second part presents a kind of design and application for outside mirror and power seat based on CAN bus. Moreover, the overall architecture of the outside mirror circuits and power seat circuits are introduced. The system based on Atmel T89C51CC01 or Philips ARM LPC2119 microcontroller with necessary periphery extended is coupled with Philips PCA82C251 to achieve data communication.
The third part describes the measurement principle of distance and control mode to the outside mirror and power seat. Furthermore, their hardware and software are narrated in detail. Computer communicates with outside mirror and power seat by CAN-bus professional tools. Finally, the experimental results show that the developed system is feasible and effective.
