摘要

全球能源及环境问题日益突出，一方面传统的燃油发动机车辆所排放的废气对空气造成严重污染；另一方面石油资源作为不可再生能源日益紧缺。地球上的石油资源总有一天会枯竭，若没有新能源或代替能源，到那时汽车将寸步难行，为此替代燃油发动机汽车已经成为现代汽车研发方向的重点，例如氢能源汽车、燃料电池汽车等。但以目前的条件和实用性来看，适应社会发展需求的只有混合动力汽车（Hybrid Electric Vehicle,简称HEV）。混合动力汽车（也称复合动力汽车，Hybrid Power Automobile）是指车上装有两个以上动力源：蓄电池、燃料电池、太阳能电池、内燃机的发电机组。当前复合动力汽车一般是指内燃机车发电机，再加上蓄电池的汽车。混合动力汽车的诞生给人类带来了很多好处，不仅减少了石油消耗，而且环境问题也得以改善，由于混合动力汽车在节能和降低排放污染方面的明显优势，因而受到很大的重视，研制开发和产业化的进程相当快。本文重点阐述了混合动力汽车的结构性能特点、工作原理，并分析介绍了混合动力汽车的控制策略、其优缺点、技术难题。

关键词：混合动力汽车，结构，原理，控制策略

ABSTRACT

The global energy and environmental issues have become increasingly prominent, waste gas emitted from a traditional fuel engine vehicle of the serious pollution of the air; on the other hand, oil as a non-renewable energy shortage. The oil resources on earth will be exhausted one day, if there is no new energy and alternative energy, then the car will can't do anything, this alternative fuel engine automobile has become the focus of modern automobile development direction, such as hydrogen energy, fuel cell vehicles. But in the present conditions and practical, to meet the needs of social development only hybrid electric vehicle (Hybrid Electric Vehicle, referred to as HEV). Hybrid electric vehicle (also known as hybrid car, Hybrid Power Automobile) refers to the vehicles equipped with more than two sources of power: power unit battery, fuel cell, solar battery, internal combustion engine. The composite power automobile generally refers to diesel generator, plus battery cars. The birth of hybrid cars have brought many benefits to human beings, not only to reduce the oil consumption, and environmental issues will also be improved, because hybrid vehicles to reduce pollution emissions has obvious advantage in energy saving and, thus greatly attention, research and development and industrialization process quite quickly. This paper describes the working principle, structure and performance characteristics of the hybrid electric vehicle, and analyses the control strategy of hybrid electric vehicle, the advantages and disadvantages, technical problems

Keywords: H ybrid electric vehicle, structure, principle, control strategy
