摘　　要：运用专利地图方法对40件混合动力汽车(HEV)高被引专利的年代分布、研发主体分布和IPC分布进行了详细地分析。结果表明:国外企业对HEV技术的研发起源较早;该领域的核心技术主要掌握于丰田和通用;未来的研发重点是蓄电池、控制系统和电数字数据处理等领域。With the method of Patent Map, this paper makes a detailed analysis on year distribution, applicants＇ distribution and IPC dis- tribution about forty highly cited HEV patents. The study shows that： the research and development about HEV has been conducting by foreign companies at a very early time; it＇s Toyota Motor Corporation and General Motors Corporation that mainly master the core technol- ogy in this area; these companies will focus on the battery, control system and electrical digital data processing in the future .
