摘  要
 电动汽车相对传统汽车具有环保，启动快，运行灵活等优点，但也存在行程短，动力弱，充电难等缺点，电动汽车的传动方式多种多样，通过合理的设计与控制可以提高电动汽车的传动效率，使其更适应人们的需求。我们通过研究与计算，得出电动汽车使用变速器的优劣，提出了dsg变速器的改进设计方案和轮毂电机的改进设计方案。随着全球能源危机的不断加深，石油资源的日趋枯竭以及大气污染、全球气温上升的危害加剧，各国政府及汽车企业普遍认识到节能和减排是未来汽车技术发展的主攻方向，发展电动汽车将是解决这两个技术难点的最佳途径各跨国汽车公司已先后开始研发各种类型的电动汽车。

Abstract
Relatively traditional electric vehicles are eco-friendly car, start fast, run the advantages of flexibility, but there is also a short trip, power weak, such as charging hard to the shortcomings of the transmission of electric vehicles a variety of ways, through the rational design and control of electric vehicles can improve the transmission efficiency to make it more adapted to the needs of people. Through research and calculated using the transmission of electric vehicles from the merits of proposed improvements dsg gearbox design and improvement of motor wheel design. With the global energy crisis deepening, the increasing depletion of oil resources as well as atmospheric pollution, global warming exacerbated the harm, governments and car companies generally recognized that energy conservation and emission reduction is the development of future automotive technology thrust, the development of electric vehicles will be to solve technical problems of these two the best way to the cross-car companies have started to develop various types of electric vehicles.
Keywords：Electric vehicle transmission design control
