插电式混合动力汽车(PHEV)因节能减排效果显著已被国内外汽车工业作为重要发展方向。然而当前PHEV仍面临着其实际燃油经济性、驾驶平顺性难以达到其理论最优值的困境，主要原因在于1) PHEV运行工况的复杂性为整车控制输入带来了随机不确定性；2) 实际运行机械-电-热能量场耦合特点暂未有系统性模型描述；3) PHEV多模式切换瞬态动力学控制问题仍未解决；4) 实现PHEV全工况高性能运行的多目标实时优化控制机制尚未完全建立。为此，项目拟借助不断发展的智能网联汽车技术，开展基于交通流时空分布的PHEV运行工况及驾驶员行为量化机制研究，建立PHEV“机械-电-热”能量多场耦合系统模型，在此基础上研究PHEV多模式耦合机制与切换瞬态平顺控制方法，研究并探索智能网联PHEV高性能运行机理与实时控制方法。研究工作将为智能网联PHEV高性能运行实时控制技术提供新的模型与控制方法。

Plug-in hybrid electric vehicle (PHEV) has already been regarded as one of most important development directions for the automobile industries at home and abroad, due to its significant effect on energy conservation and emission reduction. However, currently it is still faced with the dilemma that the actual fuel economy and drivability of PHEV cannot reach its theoretical optimal value. The main reasons are: 1) The complexity of operating conditions brings random uncertainty to the control input of PHEV; 2) There is no systematic model to describe the characteristics of mechanical - electrical - thermal energy coupled fields in practical operation; 3) The problem of multi-mode transient switching dynamics control is still unsolved; 4) The multi-objective real-time optimal control mechanism to realize the high performance operation of PHEV in the full operating range has not been completely established. For this purpose, this project intends to make use of the continuous development of intelligent network vehicle technology, carry out the researches on the PHEV operating conditions and driver behavior quantization mechanism based on traffic flow spatial and temporal distribution, and establish the model of mechanical - electrical - thermal energy multi - field coupling system for PHEV. On this basis, the multi-mode coupling mechanism and switching transient comfort control method of PHEV will be studied, and the high-performance operation mechanism and real-time control method of intelligent connected PHEV will be studied and explored. The research work will provide novel models and control approaches for the high performance real-time control technology of intelligent connected PHEV.
