混合动力电动汽车能量管理系统控制策略研究

Overview of energy management system for hybrid electric vehicle

面对能源和环境的巨大压力,混合动力汽车已成为世界汽车产业重点发展领域,其中,能量管理系统是相关研究领域的重点和难点。根据算法,现阶段的能量管理策略可以分为基于确定规则的控制策略、基于模糊规则的控制策略、基于瞬时优化的控制策略、基于全局优化的控制策略四种。文中分析并比较这四种能量管理策略,基于模糊规则的控制策略自适应性强和基于瞬时优化的控制策略精确度高,应给予关注。

Because of pressure on energy and the environment,Hybrid vehicles have become the key development areas in the car industry all over the world,the energy management system has become a difficulty in research area of hybrid electric vehicle. In this paper,several control strategies including rule- based energy management strategy,fuzzy logic control strategy,real time optimization strategy and global optimization strategy are analyzed and compared. Because of the adaptability of fuzzy logic control strategy and the high accuracy ofreal time optimization strategy,they are the research focus at present.
