智慧城市始於IBM於2008年提出的智慧地球的概念,其理念是透過資訊和訊息的技術手段使得民眾的生活變得更便捷。透過供電系統、交通系統、居家生活、供水系統、企業組織、辦公室、醫療系統、政府機關、教育系統的相互連結,產生有效的資訊,幫助民眾在工作上更有效率,享受更美好的生活。
在這樣的發展前提下,因而有了物聯網、工業物聯網、車聯網等新興產業的出現和興起,透過各式感測器的感知並產生數據後,經過高效能的運算處理系統的分析而成為了資訊,再經由網路將各種資訊串聯起來後透過AI智慧產生即時的決策和指令,使得各式設備能幾乎以無時間差的情況下進行正確的運作,也讓民眾能得到各式各樣的即時資訊,協助民眾做更有效的判斷和決策。
上述的情境在車聯網的應用中即是先進駕駛輔助系統ADAS (Advanced Driver Assistance Systems)亦或是智慧自動駕駛系統欲達成的目標。然而,以現今的車載網路技術因頻寬限制無法進行大量資料傳輸、傳輸延遲時間無法確定、網路缺乏安全保護機制、各自網域內的資訊無法相互分享、中心運算處理系統無法及時處理大量資訊等因素而無法達到聯網汽車所期待的目標。
為了改善及解決上述現今車載網路技術的限制和瓶頸,因而有了車載乙太網路的崛起,其基礎是以眾所皆知運行已久的乙太網路為其網路設計架構。由於汽車與人們的生活緊密結合,當汽車具有聯網功能後,為能確保及保障人們的安全,因此資料的傳輸延遲、網路安全、資料安全在聯網車中顯得更加的重要。車載乙太網路的技術在各方面皆比現今車載網路技術CAN Bus (Controller Area Network Bus)、 Lin Bus (Local Interconnect Network Bus)、FlexRay、MOST (Media Oriented Systems Transport)、LVDS (Low Voltage Differential Signaling) 更具優勢,且能完全滿足聯網汽車的各式功能需求。基於乙太網路已在航空、工業等產業使用多年,已足能證明乙太網路的穩定、安全、可控、可靠、快速、彈性、擴充便利等特性,足以成為引領車內網路重新架構和發展的主流技術,協助汽車商實現聯網車和智慧自動駕駛的目標。
本研究的目的旨在提供一套有系統性的分析手段標準,協助個案事業部進行車載乙太網路的技術、優劣勢、市場需求、個案事業部之競爭能力、商品、市場產值等分析,進而產出合適個案事業部的決策、產品規劃、資源分配、戰略手段及營收預估,幫助個案事業部達成各階段所規劃之目標,協助企業達成永續經營的目標。
The Smart City is from the concept of Smarter Planet proposed by IBM in 2008, the idea of Smart City is to make people's lives easier and more convenient by using information and messaging technology. The effective information can be generated through the interconnection of power supply systems, transportation systems, household living, water supply systems, business organizations, offices, medical systems, government agencies, and education systems, so that it can help people be more efficient at work and enjoy a better life.
Under such a development premise, there is the emergence and rise of emerging industries are appeared and created, such as the Internet of Things, Industrial Internet of Things, V2X (Vehicle to Everything), etc. The data generated through the perception of various sensors are analyzed by a high-performance computing processing system to become information. Then the network connects all kinds of information together and uses AI intelligence to generate real-time decisions and commands so that all kinds of devices can operate correctly with almost no time lag, and people can get all kinds of real-time information to help them make more effective judgments and decisions.
The realization of the above scenario on the V2X is the goal of ADAS (Advanced Driver Assistance Systems) or smart autonomous driving system. However, today's in-vehicle network technology is unable to transmit large amounts of data due to bandwidth limitations, the transmission delay cannot be determined, the network lacks security protection mechanisms, the information in each domain cannot be shared, and the central processing system cannot process large amounts of information in a timely manner, thus failing to achieve the desired goal of a networked vehicle.
In order to improve and solve the limitations and bottlenecks of in-vehicle network technology in above, thus the Automotive-Ethernet is emerged, the structure of Automotive-Ethernet is based on the well-known Ethernet network to design its architecture. As cars are closely integrated with people's lives, when cars are connected to the internet, to ensure and protect people's safety, the data transmission delay, network security, and data security become more important in networked vehicles. Automotive-Ethernet technology is superior to CAN Bus (Controller Area Network Bus), Lin Bus (Local Interconnect Network Bus), FlexRay, MOST (Media Oriented Systems Transport), and LVDS (Low Voltage Differential Signaling) in all aspects, and can fully meet the functional requirements of networked vehicles. Based on the fact that Ethernet has been used in aviation and other industries for many years, it has proven to be stable, safe, controllable, reliable, fast, flexible, and easy to expand, hence, the Automotive-Ethernet will become a mainstream technology, and leading the network restructuring of in-vehicle network system, so that can help automakers achieve the goals of networked vehicles and smart autonomous driving.
The purpose of the present study is to provide a set of systematic analysis means and standards to assist the business division of the case company in analyzing the technology, strengths and weaknesses, market demand, the competitiveness of the business division, products, and market scope of the Automotive-Ethernet network, in order to formulate appropriate decisions, product planning, resource allocation, strategic measures, and revenue estimates to help the business division achieve its goals and objectives at each stage of the project, so the case company can achieve the goal of sustainable operation.
