毕业论文：混合动力汽车控制现状研究.docVIP

摘 要 汽车业可持续发展所面临的两大难题，一是环境污染，二是石油资源匾乏，因此节能和环保成为当今全球汽车工业发展的两大主题，各国也争相开展绿色环保汽车—电动汽车的研制与开发。然而，由于纯电动汽车上的关键技术—电池技术的制约，使纯电动汽车的性价比远远不能达到推广应用的标准。其主要障碍包括:电池的能量密度低，从而导致电池组的质量和体积都比较大;电池组有限的循环寿命和昂贵的价格使得电动汽车的市场前景暗淡。在纯电动汽车短期内还不能实现产业化的情况下，融合传统汽车(内燃机汽车)和电动汽车优点的混合动力汽车登上了历史舞台。本文以通俗的语言说明混合动力汽车的结构和特点以及节能原理，还叙述了混合动力汽车的类型和关键技术和混合动力汽车的控制策略，最后介绍了混合动力汽车的实时控制策略让更多的人，特别是使用和维修混合动力汽车的人员对混合动力汽车又所了解，呼吁更多的人使用混合动力汽车 Abstract Sustainable development of the automotive industry faces two major problems of pollution and the second is lack of oil resources and plaque, so energy saving and environmental protection into the development of todays global automotive industry the two main themes, countries are vying to launch green cars - electric cars research and development. However, pure electric vehicles on the key technologies - cell technology constraints, so that pure electric cars cost far to promote the use of standards. The main obstacles include: the low energy density of batteries, resulting in battery quality and volume than the larger; limited battery cycle life and high prices make electric vehicle market prospects. In pure electric vehicles also can not be achieved short-term industrialization, the integration of traditional vehicles (internal combustion engine vehicle) and the advantages of electric vehicles hybrid vehicle mounted the stage of history.  This article is written in simple language to explain the structure of hybrid vehicles and energy-saving features and principles, also described the types of hybrid vehicles and key technologies and hybrid vehicle control strategy, and finally introduced the hybrid electric vehicle real-time control strategy. More people, particularly the use and maintenance of hybrid vehicles hybrid vehicles, officers know they are calling for more people to use hybrid vehicles.
