摘要

本文目的為建立一電動車之車載通訊控制系統，利用前控制系統與後控制系統為中心達到整合的目的。為了減少硬體複雜度及成本，主控系統以直接連接的方式來連結其他硬體裝置如車燈、方向燈、直流無刷馬達、溫度感知器等，僅有少數裝置如電池管理系統是以控制器區域網路協定的方式連接。如此一來如果有其他硬體裝置可以直接使用控制器區域網路協定來連接。將來利用專門的檢測儀器即可以顯示該車輛系統中的重要訊息於電腦上，利於檢測人員進行檢查或維修等動作。系統實驗平台部分，本文使用Microchip微控制器dsPIC30F4011於控制系統中來完成本文之系統整合。最後再經由UART模組以RS-232通訊協定將資料傳送至電腦人機介面，以方便使用者監控或診斷。電腦人機介面部分使用Microsoft Visual Basic 6.0做為顯示介面，即時的顯示溫度、車速、電池電壓等重要訊息，並且可以於電腦人機介面上來控制車上所有燈組訊號或馬達定速巡航等功能，達到系統整合之目的。最後，電腦人機介面將會輸出一份報告並存入Excel中，包含了行駛里程，時間，並將車速以及電池狀態製作成圖表，方便往後判斷行車資訊或是分析電池壽命。

The purpose of this study is to establish a communicate control system for electric vehicles based on two control systems. In order to reduce the hardware complexity and costs, the main control system connect directly to other hardware devices. For example, lights, brushless DC motor and temperature sensor. Only a few devices such as battery management system is connected through Controller Area Network Bus protocol to the main control system. In this way, other hardware devices can be connect easily through CAN Bus protocol, and the important information in the vehicle system can be shown through special detection equipment in the future, which will take advantages of the inspectors for inspection or maintenance. In the system experimental platform, Microchip’s microcontroller dsPIC30F4011 is utilized for both control systems to complete the system integrated, and utilize the UART module with RS-232 protocol to transmit data to the Human-Machine Interface in order to facilitate supervisory or diagnosis. In the Human-Machine Interface, Microsoft Visual Basic 6.0 is utilized for a display interface in this study, which can detect battery voltage, temperature, wheel speed and some important information in real-time displaying including light signal control or motor cruise control to achieve the purposes of system integration. Finally, the Human-Machine Interface will generate a table in Microsoft Excel, including driving distance, driving time, chart of speed and battery status which can determine the battery life and the vehicle information easily in the future.
