以控制器區域網路總線為基礎之混合控制單元實現於XIL系統

Abstract

現今一款新的房車和過去相比，車內的電子控制單元(ECU)數量非常的多，有小型的電子控制單元來控制小型電子原件，如：車燈、儀表板、窗戶，也有較大型的電子控制單元，如：混合動力單元、馬達驅動器……等。因此車內各電子元件之間訊息交換十分頻繁，此時通訊協議便顯得十分重要，本論文將先介紹幾個常見通訊方式的基本架構與優缺點，並挑選最適合的通訊方法，再介紹微控制板(MPC)內的控制器區域網路模組之架構，以及各個所需要注意的事項與設定方法，進而運用現有的微控制板，做一個以控制器區域網絡(CAN)為基礎的通訊測試，並將之與dSPACE內的整車系統做連結，搭配簡易的動力分配方法對dSPACE內的動力系統進行控制器區域網絡之通訊測試，通訊測試的結果為正確並可成功連結各系統。

Compared to traditional vehicle, the number of electronic control units inside the modern vehicle is much greater. Small electronic control units control the small electronic components, such as lights, dashboards, and windows. There are larger electronic control units, the hybrid control unit, the motor drives, etc. Since the various electronic components exchange messages frequently, the communication protocol is very important. This thesis will introduce the basic architecture the advantages and disadvantages of several common means of communication first, and determine which communication method should be implemented. Second, Controller Area Network (CAN) module’s architecture of the MPC, precautions and setting methods will be discussed. The CAN of the existing micro-controller is tested within the MPC initially, and then the MPC is connected to the vehicle’s power train model within the dSPACE to conduct communications test of the CAN with a simple power distribution method. Analysis of the test results is exercised and the communication is confirmed to be successful.
