摘　　要：随着现代化汽车工业和电子技术领域的快速发展,车载媒体系统已经成为车载信息系统设计过程中的一个重要关注点.车载媒体系统的移动性、互联性、社交性是国内外车载多媒体技术发展的关键.同时,安全性又是整个汽车系统中最重要的性能指标.本文提出了一种在共同网络下的媒体共享方案.通过研究基于UPnP(通用型即插即用)的车载媒体共享系统,保证汽车网联安全性的前提下,实现了汽车媒体共享的功能,有效降低了外来网联设备对汽车的入侵风险.测试结果表明,该系统达到了整体的设计要求且具有较高的稳定性.With the rapid development of the modern automotive industry and the field of electronic technology,in-vehicle media systems have become an important focus in the design process of on-board information systems.The mobility,interconnectivity and sociality of in-vehicle media systems are the key to the development of in-vehicle multimedia technology at home and abroad.At the same time,safety is the most important performance indicator in the entire automotive system.Therefore,this paper proposed a media sharing scheme under a common vehicle network.Through the research of UPnP(Universal Plug and Play)-based vehicle media sharing system,the basic function of car media sharing was realized on the premise of ensuring the safety of the car in the network connection,which effectively reduced the external invasion risk.The test results showed that the system met the overall design requirements and had the good stability.
