摘要
混合动力汽车同时采用内燃机和电机作为驱动源,可以同时克服传统内燃机工作效率低和纯电汽车行驶里程短的问题.如何对两种驱动源进行合理分配成为了混合动力汽车能量管理的关键问题.这里针对一款复合功率分流式动力系统搭建了AMESim和MATLAB/Simulink的联合仿真平台,并在NEDC和WLTC工况下仿真分析了基于规则的CS能量管理策略和基于动态规划算法的能量管理策略.得出基于动态规划算法的能量在NEDC和WTLC下工况的最优燃油消耗量分别为5.77L/100km,6.57L/100km;相较于规则控制策略分别降低了4.15%、6.3%.
Abstract
Hybrid electric vehicle uses internal combustion engine and motor as driving source,which can overcome the problems of low efficiency of traditional internal combustion engine and short driving range of pure electric vehicle.How to distribute the two driving sources reasonably has become the key problem of hybrid electric vehicle energy management.A co-simulation plat-form of AMESim and MATLAB/Simulink is built for a compound power split power system.The energy management strategy of CS based on rules and energy management strategy based on dynamic programming algorithm are simulated and analyzed un-der NEDC and WLTC conditions.The optimal fuel consumption of NEDC and WLTC based on dynamic programming algorithm is5.77L/100kmand6.57L/100kmrespectively,which is reduced by4.15%and6.3%compared with the rule control strategy.
