本文研究以FlexRay應用於車身網路通訊問題,輔以適當通訊協定運作及時間週期等參數之設定,並讀取資料框架存取時之錯誤訊息,如協議類型錯誤(SOS)、混串音(BIT)、拜占庭(Byzantine messages)、死結(Deadlock)、派系(Clique)等,分析於不同通訊週期下資料框架存取錯誤量及其資料框架遺漏百分比,並應用FlexRay節點於車輛資訊系統示教板之控制,並以個人電腦監看車輛資訊系統示教板之通訊狀態。
分析FlexRay群組節點間通訊,分為兩組群組節點(每一群組含兩個節點),以監測軟體紀錄資料傳遞之訊息,從單節點收發資料訊息,拓展至群組節點間之通訊於各種拓撲之組合,即FlexRay群組節點之多種拓撲組合建立於車輛電子系統中,可組合為混合拓撲架構,如派系問題需至少兩群組節點之架構下實驗,據以通訊協定運作參數及時間週期參數之配置,探討節點於不同通訊週期下,節點間通訊傳輸之可靠度。

The In-Vehicle Network system which connects and share data with the electronic systems in a vehicle becomes one of the indispensable researches for the Automotive Electronics in the future. Therefore, my dissertation research the communication problems for In-Vehicle Network based on FlexRay, such as SOS (Slightly-Of-Specification), BIT (Babbling-Idiot Transmissions), Byzantine messages, Deadlock, Clique, and show the example of Clique.
There are two clusters, we analyze and monitor the nodes of FlexRay with Protocol Control Data configuring the messages of communication, and we developing the reception interface of FlexRay from the single node communication to four nodes via linear passive topology applied to the Vehicular Electronic System Board.
Finally, we access the error's messages from data frame's transmission and record the number of lost data with parameters of protocol's related-operation, monitor status of communication between node and Vehicular Electronic System Board for the enhancing the reliability of FlexRay’s communication.
