本文主要探討CAN-Bus通訊協定（CAN2.0B及ISO11898）及節點電路之設計與應用；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，並應用於車用電動後視鏡上。本研究採用Nissan Cefiro折疊式電動後視鏡，並於後視鏡上加裝電位計以進行位置回饋。CAN節點電路則是以Atmel之微控制器(T89C51CC01)，搭配Infineon的收發器(TLE6250)，整合製作完成。實驗結果顯示，使用CAN節點電路，進行電動後視鏡之控制，可符合新世代車身電子資訊通訊網路控制與電腦診斷之需求。

This paper mainly aims at CAN-Bus communication protocols (CAN2.0B & ISO 11898) and develops node technology. Meanwhile we also develop CAN controller and receiver for electronic rear-view mirrors in vehicle. This research adapts Nissan Cefiro folding electronic rear-view mirror, and install potential meter to count and feedback the position of the rear-view mirror. We use Atmel microprocessor (T89C51CC01) to design node circuit, combine with Infineon transceiver (TLE6250). A desirable preliminary result has been achieved. The electronic rear-view mirror with CAN-Bus node, can accord with the CAN-Bus communication network as well as the PC-based diagnostic system.
