摘要
为改善功率分流式约束活塞混合动力系统的燃油经济性,设计了基于规则的能量管理策略。在分析混合动力系统结构的基础上,建立了功率分流式混合动力系统模型;对系统工作模式进行了分析,制定了基于规则的能量管理策略,实现各动力源的功率分配;在MATLAB/Simulink中建立仿真模型,验证能量管理策略的可行性与准确性。在新欧洲行驶工况下的仿真结果表明,该策略能够保证约束活塞发动机基本运行在最优工作区,并且可以有效地分配约束活塞发动机的输出功率,使系统具有良好的燃油经济性。
Aiming at the power-split constrained piston hybrid power system,in order to improve the fuel economy of the system,a rule-based energy management strategy is designed.By analyzing the structure of the hybrid power system,the model of power-split hybrid power system is established.Then the working mode of the system is analyzed,and the rule-based energy management strategy is formulated to realize the power distribution of each power source,and the simulation model is established in MATLAB/Simulink to verify the feasibility and accuracy of the energy management strategy.The simulation results of new european driving cycle show that the strategy can ensure that the constrained piston engine basically runs on the optimal working area,and can effectively distribute the output power of the constrained piston engine,and the system has good fuel economy.
