混合动力汽车（HEV）是在电动汽车发展过程中出现的一种低油耗、低排放、续驶历程长、价格适中，兼具纯电动汽车和传统燃油汽车优点的新型汽车，由于在技术、经济和环境等方面的综合优势，HEV 被认为是目前最切实可行的清洁汽车方案。本文以混合动力轿车项目及其整车控制系统子课题为背景，主要研究HEV 的控制策略及其在实车上的应用。包括用matlab对汽车及其控制系统建模优化。(Hybrid electric vehicle (HEV) is in the process of development of electric vehicles the emergence of a low fuel consumption, low emission, long-driving course, affordable, both pure electric vehicles and conventional fuel vehicles the benefits of new cars, due to technical, economic and environmental aspects of the comprehensive advantages, HEV is considered to be the most viable clean vehicle program. In this paper, hybrid cars and the vehicle control system sub-project issues as background, the main research HEV control strategy and its application in the real car. Including the use of matlab modeling of the vehicle and its control system optimization.)
