从内地到西藏及西藏、青海省内的主要交通工具为汽车运输,进行高原汽车运输的研究对于发展两省(区)的民族经济及国防建设事业有重要的意义.该地区内行驶条件恶劣,尤其公路干线——青藏公路的昆仑山及唐古拉山区,海拔高,气候变化多端,令人难以预测,空气稀薄.汽车运输亦因条件恶劣出现了功率显著下降、冬季起动困难,刹车气压不够等一系列问题.成为汽车运输行业和生产部门的重要研究课题之一. From the hinterland to Tibet, Tibet and Qinghai Province, the main mode of transportation is automobile transportation. The research on the transportation of plateau motor vehicles is of great significance to the development of national economy and national defense construction in the two provinces (autonomous regions) .However, In particular, the highways and the Kunlun Mountains and Tanggula Mountains of the Qinghai-Tibet Highway have high altitude and unpredictable climate, and are thinly air-conditioned. Due to poor conditions, the transportation of motor vehicles has also seen significant drop in power, difficulty in starting in winter and insufficient braking pressure Series of issues.As the automotive transportation industry and production department one of the important research topics.
