隨著汽車功能的不斷增加，可靠性要求的不斷提高以及價格的不斷下降，越來越多的電控單 元(ECU)將被引入到汽車中。目前高階汽車一般會有50個以上的ECU。因此，為了使這些ECU能夠 在一個共同的環境下協調工作，也為了進一步降低成本，人們設計了針對車載通訊電子網路的匯 流排協定。如果我們可以讓這一些ECU與ECU之間能夠互相通訊，那麼資料將會傳遍車身各個控 制設備，這對將來車用控制系統來說是一項重要的技術。因此，本論文中我們先從最基本的馬達 控制做起，主要是去研究如何透CAN Bus網路匯流排來將馬達的控制資訊傳遞出去給其它的ECU。 最後，我們也針對這樣的技術，去實作CAN Bus的實驗，實驗結果更顯示了 CAN Bus的資料傳遞具 高可靠度、便利性與實用性，特別是使用在車用整車控制系統之上。

The automobile functions and reliability are increasing in rapidly, but the price is in decreasing. Therefore, there are more and more ECUs (Electronic Control Unit) will be conducted into the car. Currently, there are about more than 50 ECUs used in the high-level automobile. Therefore, peoples design CAN Bus to decrease the development cost for car such that the ECUs can be worked coordinately for each other. If we can make the ECUs communicate each other, the data message will be sent to each control device. It is an important technology for car-based control system. Therefore, we first introduce the motor control which is to research how the control message is delivered out via CAN Bus. Based on this technology, we consider having a programming to practice an experiment. The experiment results show that the CAN Bus can deliver control messages in reliably，conveniently and practically, especially in car-based control system.
