本文主要目的在於發展可載入開放式診斷資料交換格式檔案（Open Diagnostic data eXchange, 縮寫爲ODX）之CAN-ECU診斷服務功能自動測試環境。本研究使用Vector商用車輛網路開發工具－CANdelaStudio，並依據診斷通訊協定ISO 14229-1，編輯診斷資料，輸出ODX檔案。其次，在CANoe環境中載入ODX檔案，建構虛擬CAN-ECU的診斷功能，以及用來進行診斷功能自動測試的測試模組。診斷功能模擬測試結果與電子控制單元(ECU)規格文件是一致的，所有項目的測試步驟、過程與結果，也都記錄在測試模組所產生超文字連結語言(HTML)測試報告中。本文所建立的「CAN-ECU診斷服務功能自動測試」方法，可以協助汽車製造廠與ECU供應商，在ECU診斷服務功能研發時期，儘早發現錯誤與缺陷，並可節省ECU開發成本及提升開發效率。

This paper describes the development of an environment which can load ODX files to perform the CAN-ECU functionality test. The vehicle network tools-Vector's CANdelaStudio can be used to edit the diagnostic data which are based on ISO 14229-1 and then export ODX files. When loading the ODX files within Vector's CANoe, it is possible to implement diagnostic functions of a CAN-ECU node mode that can be tested automatically by the test module. Finally, the testing results are compliant with ECU specification and displays in HTML test report are generated by test module. The results in this paper could help the OEMs and ECU suppliers to detect the errors and defects of diagnostic functionalities of the CAN-ECU in early development stage, and save the costs as well as improve development efficiency.
