摘　　要：建立传统车辆和液压混合动力车辆的关键部件数学模型并在Matlab/Simulink平台下搭建仿真模型。提出并分析基于规则的能量管理策略,设计了4种模式策略,同时在STATEFLOW模块中实现其模式策略的控制逻辑。仿真验证表明:所设计的基于规则能量管理策略可以满足液压混合动力车辆的总功率需求,使其发动机运行于最佳燃油经济性区域;通过燃油经济性曲线对比,得出液压混合动力车辆燃油经济性有较大提高。The mathematical models were established based on the key components of the traditional vehicle and hydraulic hybrid vehicle.The simulation model was built under the Matlab/Simulink platform.The energy management strategy based on rules were proposed and analyzed and four modes were designed correspondingly.The control logic of its modes were implemented in the STATEFLOW module.Simulation results showed that the program could meet the total power demands and the engine ran in the best fuel economy area.The fuel economy of the hydraulic hybrid vehicle was improved by comparing fuel economy curves.
