摘　　要：在汽车动力学基础上,对ISG型中度混合动力汽车在不同工作模式下的系统效率进行瞬时优化,以系统效率最高为优化目标,得到工作模式切换规律。在瞬时优化结果的基础上,采用全局最优化方法,分别计算在不同工况下道路循环单元ECE和EUDC的油耗与SOC变化值。根据油耗与SOC变化值,对不同工况下的循环单元进行排列组合,制定了十种不同的能量管理策略。仿真结果表明,根据不同的道路情况和驾驶意图,可以选择最优的能量管理策略,以达到降低油耗和平衡SOC的目的。Based upon the vehicle dynamics,the system efficiency of medium hybrid electric vehicle（HEV） at different operation modes was transiently optimized in order to improve the fuel economy.And then,the operation mode switch law of medium HEV was proposed for the best hybrid system efficiency optimization.With the results of Transient Optimization,the fuel consumption and delta SOC of driving cycle units ECE and EUDC at different operation modes were calculated individually by Global Optimization.According to the calculation results,ten different energy management strategies of medium HEV were developed by using permutation and combination algorithm for driving cycle units at different modes.The simulation results show that the optimized energy management strategy is gained according to the different road condition and driving intention to reduce fuel consumption and balance the SOC.
