摘要/Abstract

摘要：

针对固定循环工况下所制定的混合动力汽车能量管理策略存在一定局限性问题,从ADVISOR软件中选取覆盖车辆实际行驶工况的20个典型循环工况,以整车综合燃油消耗和动力电池寿命为综合优化目标,利用粒子群算法对各工况下能量管理策略中所涉及的关键参数进行了优化,并将得到的优化结果建立数据库,提出了基于行驶工况识别的混合动力汽车动态能量管理策略。最后,通过选择某个随机工况对所制定的能量管理策略进行仿真。结果表明：所制定的动态能量管理策略与未采用工况识别的能量管理策略相比,车辆综合燃油消耗下降10.70%,动力电池温升和平均有效工作电流分别下降2.46℃和1.63A。

关键词: 混合动力汽车, 工况识别, 随机工况, 动态能量管理策略

Abstract:

Energy management strategy of HEV which was built in invariable cycle condition existed some limitations. 20 typical cycle conditions which standed for vehicle real driving conditions were chosen from ADVISOR software and key control parameters of each driving cycle were optimized by using particle swarm algorithm as the comprehensive goal of vehicle total fuel consumption and power battery life, relevant optimized results were saved in database, an energy management strategy of HEV based on driving pattern recognition was proposed. Finally, simulation for the energy management strategy was carried out under a random driving condition, simulation results show that vehicle fuel consumption is cut down 10.70%, temperature rise and average operation current are cut down 2.46℃ and 1.63A respectively by using dynamic energy management strategy compared with energy management strategy without driving pattern recognition.

Key words: hybrid electric vehicle(HEV), driving pattern recognition, random driving condition, dynamic energy management strategy
