近年來,隨著車輛電子的快速發展,世界各主要半導體大廠亦切入此領域,並進行相關產品的研發。而根據不同的電子控制單元(ECU),如速度或是單價等需求,車輛電子發展出LIN、CAN、FlexRay與MOST等車載通訊網路。其中,隨著車輛系統的線傳控制技術需求,FlexRay已朝整合式車用控制網路系統發展,包含車體系統、主被動安全系統、動力系統、和資訊系統,都整合於FlexRay網路架構上,充分展現FlexRay在高頻寬和高安全性應用方面的優勢。因此,FlexRay已成為車輛電子通訊網路技術發展的重要關鍵。
本研究架構主要是由個人電腦主機端,透過RS-232連接至微控制器與內嵌FlexRay介面結合而成的FlexRay ECU節點。整體通訊網路運用點對點與匯流排等多種網路拓璞方式相互連接,並執行類比/數位轉換與數位輸入/數位輸出等控制動作。每一FlexRay ECU節點不僅完全符合FlexRay通訊協定,亦實現出FlexRay與CAN通訊網路閘道器。
透過本研究所實現的高速車輛電子通訊網路,可以進行ECU節點間訊號傳輸,並由個人電腦接收FlexRay通訊網路訊號,進而有效監測與控制各個高速網路節點。此外,透過CAN與FlexRay傳輸方式轉換,可完成車載主要網路與次網路之間的通訊以及高速與即時性的線傳控制等功能。而經實際測試結果,證明了本研究所建置的FlexRay車載通訊網路系統已可提供給高速車載通訊網路一個極佳的評估與驗證平台。
In recent years, the rapid development of e-vehicles, each one of the major semiconductor manufacturers have entered this field of research and development and related products in the world. Depending on the electronic control unit (ECU), such as speed or price, and other needs, the development of vehicle electronic LIN, CAN, FlexRay and MOST network, such as the vehicle.As the vehicle by-wire system technology needs, FlexRay has been towards integrated vehicle control systems development network, which covers the body systems, active and passive safety systems, power systems, and information systems are integrated in the FlexRay network infrastructure, fully demonstrate the high bandwidth and high security applications the advantages of the FlexRay.
Therefore, FlexRay has become the vehicle of technological development of electronic communication network key. Study the structure mainly by the personal computer through the RS-232 interface connected to the micro-controller with embedded FlexRay interface based on a combination of node FlexRay ECU. The use of the entire communications network interconnected with the bus in a variety of point-to-point network topology, and the implementation of analog / digital conversion and digital input / digital output control action. FlexRay ECU each node not only in full compliance with the FlexRay protocol, FlexRay and also the realization of a CAN network gateway.
Through research to achieve high-speed vehicle electronic communications network, ECU can transmit signals between the nodes by the personal computer to receive signals FlexRay network communications, and effective monitoring and control of all high-speed network node. In addition, CAN and FlexRay conversion by means of transmission can be completed by the main network and subnet as well as high-speed communication between the line and real-time control function Communication network in the vehicle. Research proves that building the FlexRay automotive communications network system has been available for high-speed automotive network communications an excellent platform for assessment and verification through the actual test results.
