摘　　要：绘制增程式电动车专利地图,从技术研发规模、技术及产业发展趋势、重点技术领域、地域分布和竞争机构等方面展开专利分析。结果表明:增程式电动车产业技术从1995年左右开始高速发展并持续至今;充电控制和增程器控制技术为国际产业研发的焦点;技术热点向安全和监测、电量测量和可行驶里程指示、牵引电机、车辆微处理器系统等技术迁移;美日韩等国竞相在中国进行专利布局,形成较强专利壁垒,为突破专利壁垒,中国公司可考虑与电装、马自达、现代、三菱等技术实力较强但在中国专利布局力度较弱的公司合作。The paper draws a patent map of extended-range electric vehicle（EREV）, and analyses the patents from aspects of technical RD scale, development trends of technology and industry, fields of key technologies, regional distribution and competitors.The results show that EREV technology has developed rapidly since 1995; charge control and range extender control are the focuses of international RD; technology hotspots shift to safety and monitoring, battery measuring and driving range indicator, traction motor and vehicle microprocessor system; United States, Japan and Korea race to conduct patent layout in China to form strong patent barriers,and Chinese companies may consider to cooperate with Denso, Mazda, Hyundai and Mitsubishi which have strong technical strengths but weak patent layouts in China, to break the patent barriers.
