1、浅析混合动力汽车系统的结构与原理09汽服郭永强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废气排放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，具备商业化运作条件的只有混合动力汽车（HybridElectricVehicle，简称HEV）。混合动力汽车（亦称复合动力汽车，英文为HybridPowerAutom

2、obile）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。混合动力汽车的问世给人类带来了诸多好处，不仅石油消耗减少了，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，控制策略目录1绪论·······················
