摘　　要：在节能减排的大背景下,能量管理控制策略是决定混合动力车辆动力性、经济性和排放性的关键因素。文章基于MATLAB建立了单轴并联式混合动力汽车及其零部件的数学模型,在系统建模的基础上,提出了一种基于最小等效油耗预测模型(ECMS-MPC)的能量管理策略,并与动态规划(DP)的能量管理控制策略进行了比较。仿真结果表明,从技术结果上,ECMS-MPC控制策略接近DP能量管理控制策略;从计算效率上,ECMS-MPC控制策略比DP能量管理策略提高了6倍,论证了ECMS-MPC控制策略的优越性。Under the background of energy conservation and emission reduction,energy management and control strategy is the key factor to determine the power,economy and emission of hybrid electric vehicles.In this paper,the mathematical model of the single axle parallel hybrid electric vehicle and its components is established based on MATLAB.On the basis of system modeling,an energy management strategy based on the minimum equivalent fuel consumption prediction model control(ECMS-MPC)is proposed and compared with the energy management and control strategy of dynamic programming(DP).Simulation results show that ECMS-MPC control strategy is close to DP energy management and control strategy in technical results.In terms of computing efficiency,ECMS-MPC control strategy is 6 times higher than DP energy management and control strategy.The superiority of ECMS-MPC control strategy is demonstrated.
