隨著科技的進步，自動駕駛汽車所需之相關技術也愈趨成熟。自動駕駛汽車上路有兩個技術 發展重點，一為主動式感測技術，二為協同式資料運算；後者多仰賴通訊技術進行資料交換與蒐 集形成所謂車聯網(V2X, Vehicle-to-Everything)服務。為符合車用環境， 比較熱門的通訊技術大 多具有適用於戶外環境的特性，例如5.9GHz DSRC ;(Dedicated Short- Range Communication)以及 LTE(Long Term Evolution)，制定LTE的3GPP (3rd Generation Partnership Project)自Release 14開始 加入有關V2X (Vehicle-to-Everything)的議題。本文將針對3GPP現階段進行討論的LTE V2X服務 與系統需求做介紹。

Sensor technologies and Date fusion algorithm are mature for autonomous driving. The input source of data fusion algorithm depends on advance communication technology also called Vehicle-to-Everything. The communication technology for this purpose should be suitable for outdoor environment. For example: 5.9GHz Dedicated Short -Range Communication and LTE (Long Term Evolution). 3rd generation partnership project adds the topic of V2X (Vehicle-to-Everything) since release version 14. This paper will introduce the LTE V2X service requirement and system architecture.
