中文摘要： 发展电动汽车是解决当今世界能源和环境危机行之有效的重大举措。混合动力汽车（HEV）最具产业化前景，必将是汽车工业发展的主流方向之一。HEV是一类典型的连续和离散动态并存且交互作用的高度非线性、强耦合混杂动态系统，其优化控制可归结为一类有约束的非线性多目标优化问题，常规控制方法难以解决，亟待寻求新理论和新方法予以突破。本项目拟从探究HEV多工作模式切换本质入手，基于混杂切换系统理论分别研究HEV多频段混杂切换系统建模及稳定性问题、HEV动态系统振荡特性及切换瞬态过程分析与整车频率规划、基于超前控制的HEV工作模式平滑切换、计及驾驶性与NVH主动优化的HEV动力总成系统控制和管理策略开发等问题，并搭建试验平台验证新理论方法的有效性。本项目属电工技术、车辆工程和控制科学等多学科交叉的前沿研究，不仅对突破HEV产业化进程关键瓶颈具有重要意义，而且对相关学科的理论和应用研究有显著促进作用。

英文摘要： The development of electric vehicle is an effective and strategic measure to deal with the worldwide energy and enviromental crisis. As a kind of electric vehicle with the most broad industry prospect, hybrid electric vehicle (HEV) will become one of the main future orientation of vehicle industry. HEV is a class of highly nonlinear and strong coupling hybrid dynamical system consisting of interacting continuous-time and discrete-event dynamics. The optimization of HEV can be concluded as a class of constrained nonlinear optimization problem with multiple objectives, which is difficult to be solved by using traditional control approach. Therefore, it is very urgent to establish new theory and methods to resolve it. Starting with the nature of multi-modes switching, many key problems will be studied here. For example, the mix-bandwith hybrid switching system model of HEV will be constructed, and the system stability will be analyzed. The dynamical oscillation property and the switching transient behavior will be analyzed, and the problem of complete vehicle frequency planning will be studied. The smooth mode transition of HEV will be achieved based on preemptive control. Then, energy management strategy of HEV considering active drivability and NVH optimization will be developed. Finally, the effectiveness of the
