ISO14229之車輛診斷通訊協定技術(ARTC)

智慧車載資通訊技術暨服務發展計畫

本技術提供符合ISO 14229規範之車輛診斷服務通訊協定，主要包含車內電子控制器診斷軟體與車外測試設備軟體，所有軟體皆以 ISO 14229-1、ISO 14229-2、 ISO 14229-3、 ISO 14229-5、ISO 13400-2、 ISO 15765-2等多個國際標準規範為建置基礎，實現車輛診斷通訊協定技術；在應用層的部分，實現ISO 14229中的七大診斷服務通訊協定，包含錯誤碼詢問功能、錯誤碼清除功能、要求重置功能、狀態維持功能、週期性資料回傳功能、狀態變更功能、依據識別碼要求資訊功能，並根據ISO 13400-2、 ISO 15765-2之規則，進行封包包裝、切割與傳輸；透過車外診斷設備，可與車內電子控制器溝通並呈現符合標準協定之車輛診斷服務。本技術可協助實現符合國際標準規範之車身診斷通訊協定。

This technology provides software complying with standard communication protocol of diagnostic services for road vehicles. It consists of diagnostic software inside on-vehicle electronic control units and external testing software. All the software implementations are based on international standards, including ISO 14229-1、ISO 14229-2、 ISO 14229-3、 ISO 14229-5、ISO 13400-2, and ISO 15765-2. Following ISO 14229, communication protocols of seven diagnostic services were developed: Diagnostic Session Control, ECU Reset, Read Data By Periodic Identifier, Tester Present, Read Data By Identifier, Clear Diagnostic Information, and Read DTC Information. We follow ISO 13400-2 and ISO 15765-2 for information packaging, message dividing and transmission. This technology can help the development of diagnostic services for road vehicles.
