【摘要】 根据道路试验记录的数据建立驾驶员需求功率的马尔可夫模型,利用马尔可夫决策理论获得混合动力汽车的随机能量管理策略。借助燃料电池混合动力汽车控制系统的仿真平台进行仿真计算。北京公交车中速工况的仿真结果表明,与原先的恒电压控制策略相比,随机能量管理策略可以降低燃料消耗。更多还原

【Abstract】 A Markov model for driver’s power demands is set up based on road test data,and a stochastic energy management strategy for fuel cell hybrid electric vehicles(FCHEV) is worked out by applying Markov decision theory.A simulation is conducted with a platform for control system of FCHEV.The results of test on a public bus at medium speed in Beijing show that the stochastic energy management strategy is better than the original constant-voltage control in fuel consumption.更多还原
