混合动力电动汽车关键技术

混合动力电动汽车（HEV）的核心是混合动力驱动系统，HEV系统具有高度的复杂性，混合动力系统设计的关键是系统结构的选择，整车能量管理策略的开发和系统参数的确定。功率分别是系统能量管理策略研究的关键，随着研究的深入，自适应控制，模糊逻辑控制，神经元网络控制等方法也得到了有效的运用。文中对子系统的关键技术及整车试验方法一评价体系的建立等方面进行了讨论。

Key Technology of Hybrid Electric Vehicle

The kernel of Hybrid Electric Vehicle (HEV) is the hybrid power drive system. HEV system is of highcomplexity. The keys of hybrid power system design are selection of system structure, developing of vehicle energy man-agement strategy and decision of system parameters. Power distribution is the key of system energy management research.As deepening of research, adaptive control, fuzzy logic control and neuroid control have been applied to this field effec-tively. The key technology of subsystem. vehicle test method and establishing of evaluation system are discussed in the pa-per.
