摘要
文章以并联式新能源混动汽车作为研究对象,根据其工作模式提出一种能量管理策略,实现工作模式的平稳切换及混动系统的动力分配。通过Matlab/Simulink软件建立整车控制策略数学模型,对所设计逻辑门限能量管理策略的有效性进行验证。仿真结果表明:所设计的新能源混合动力汽车能量管理策略可以在满足车辆行驶性能的同时,有效提高24.2%的燃油经济性,减少排放,实现节能减排的目的。
Taking parallel new energy hybrid vehicle as research object,an energy management strategy is proposed according to its working mode to realize smooth switching of working mode and power distribution of hybrid system. Mathematical model of vehicle control strategy is established by using Matlab/Simulink software to verify the validity of logic threshold energy management strategy. The simulation results show that the new energy designed is effective. The energy management strategy of source hybrid electric vehicle can effectively improve the fuel economy by 24.2%,reduce emissions and achieve the purpose of energy saving and emission reduction while satisfying the driving performance of the vehicle.
