基於控制器區域網路建構電動車雲端監控模擬系統
Cloud Simulation System Based on the CAN Bus of the Electric Vehicle
摘要
現今智慧汽車的性能已經顛覆人們過往對交通工具的理解，從以往的被動式安全系統漸漸走往主動式安全系統，例如主動式防碰撞系統、電子車身穩定系統以及主動緊急煞車系統等；上述系統皆可細分為感測、通訊及驅動部分，這些都必須以微控制器核心，整合成節點，並以車用網路將這些節點連接，多開發一個節點功能，即為智慧汽車添加性能。為了減少整合開發節點之耗費成本及時間，系統俱備網路通訊溝通能力，本論文致力於建立一個以小型電動車為載具，開發車用節點並測試車用網路系統。網路建置將使用控制器區域網路(Controller Area Network, CAN)來進行，模擬系統將採用新唐科技製造的NuTiny-SDK-NUC140微處理器與多種電子元件，建立電子控制單元，實現能夠輔助駕駛、驅動車體、安全防護等功能的節點，如：駕駛酒精測試節點、方向盤控制節點、車體驅動節點、防碰撞節點、前輪方向感測點、智慧車燈節點，以及在整體系統上擔任輔助與監測角色的藍芽通訊節點、監視序列埠節點。除此之外亦建立能夠儲存CAN Bus訊息的雲端硬體設備端，為了解決對於微處理器儲存空間的不足，將訊息資訊傳至建立在雲端設備資料庫。透過本論文建立的開發環境之後，即可用此環境來進行更多項目的車用網路節點開發，以及網路之規劃，並可將儲存於雲端資料庫內容的分析，能更加延伸未來先進智慧汽車的開發。

Nowadays, the performance of intelligent vehicles completely has subverted people’s understanding of the past. The passive safety systems are progressed into the active protection systems, such as the anti-collision system, the electronic stability program, the autonomous emergency braking system, etc. These systems can be divided into sensing, communicating, and driving parts, which are integrated by the microcontrollers as the nodes. To develop the functions and increase the performance of the nodes, the thesis is devoted to establish a test environment of a small electric vehicle with network systems. The simulation system will be built the nodes by the NuTiny-SDK-NUC140 with the Controller Area Network (CAN). The nodes with the electronic elements can inform and assist the driver to control the vehicles. For example, we have established the nodes of the Breath alcohol test, the steering wheel control, the car auxiliary driving, the collision warning avoidance, the front wheel angle sensing, the intelligent lights, the Bluetooth communication, and the serial port monitor. We also build the cloud instrument to upload the messages of CAN bus on the web server to extend the memory of the microcontrollers. By the building environment, we can do more projects of the advanced applications and analyze the data of the vehicles on the cloud database.
