摘要

首先，分析了汽车智能化、网联化趋势，以及汽车电子电气架构（electrical electronic architecture，EEA）演进给车内通信带来的新需求与新挑战，指出车载光通信也会经历类似电信运营商固定接入网的“光进铜退”的发展历程，实现从“窄带通信+铜缆线束”向“宽带通信+光纤线束”的变革。其次，提出车载无源光网络（vehicular passive optical network，V-PON）的技术路线与标准建议：针对车内通信需求及特殊工作环境带来的挑战，在已有PON技术的基础上进行适应性改进，攻克相关核心技术，形成V-PON标准规范。该方案可充分发挥中国在光通信及PON领域的技术优势和规模产业优势，助力中国在车载通信领域形成核心知识产权，为智能网联汽车转型升级提供支撑，进而提升中国相关产业的国际竞争力。

Abstract

Firstly

the trends of vehicle intelligence and connectivity were analyzed

along with the new requirements and challenges imposed on in-vehicle communication by the evolution of automotive electrical electronic architecture (EEA). It was pointed out that vehicular optical communication would undergo a development process similar to the “fiber replacing copper” transition in telecom fixed access networks

shifting from “narrowband communication + copper wiring harnesses” to “broadband communication + optical fiber harnesses”. And then

a technical roadmap and standardization proposal for vehicular passive optical network (V-PON) were presented. To address the demands of in-vehicle communication and the challenges posed by its unique operating environment

adaptive improvements were made for existing PON technologies

and key technical hurdles were overcome to establish the V-PON standard framework.This approach fully leverages China’s technological and industrial advantages in optical communication and PON systems

facilitating the development of core intellectual property in vehicular communication. It supports the transformation and upgrading of intelligent connected vehicles (ICV) and enhances the global competitiveness of China’s automotive and telecommunications industries.
