摘要
提出了一种新的基于整个动力总成系统能量转换效率最优的混合动力汽车发动机稳态优化控制策略,确定了发动机最优怠速运行点和对应的电机最优驻车发电功率。仿真结果表明,运用发动机优化策略的混合动力汽车与传统汽车相比,基于中国乘用车城区瞬态循环的燃油经济性提高了14.3%。
An engine steady-state optimization strategy is proposed for optimizing energy Conversion efficiency of the whole powertrain of hybrid electric vehicle （HEV）. In addition, the optimal engine idling operation point and the corresponding optimal electricity generation power of electric motor at idling condition are determined. The simulation results indicate that with China urban driving-cycle, the fuel economy of HEV adopting engine optimized strategy is improved by 14.3% compared with the conventional HEV.
