摘要
针对搭载回流式动力耦合传动系统的插电式混合动力汽车(PHEV,plug-in hybrid electric vehicle),提出了一种参数匹配优化设计方法。建立了整车各个模式下的等效输入功率模型,根据最小等效输入功率原则制定了各驱动模式间的切换规律,并设置控制参数系数对模式切换曲线进行调整。通过MATLAB/SIMULINK构建了整车经济性仿真模型,利用遗传算法对匹配的动力参数和控制参数系数进行了综合优化。仿真结果比较表明:此方法得到的一组参数能有效提升燃油经济性,百公里等效燃油消耗比优化前降低了4.8%。
A parametric matching optimization design method is proposed for plug-in hybrid vehicles equipped with the reflux power coupling transmission system.The equivalent input power model for each mode of thevehicle is established.Based on the principle of minimum equivalent input power,the switching rules between different driving modes are established,and the control parameter coefficients are set to adjust the mode switching curve.The economic simulation model of the whole vehicle is built by MATLAB/SIMULINK,and the matching dynamic parameters and control parameter coefficients are optimized by genetic algorithm.The simulation results show that the set of parameters obtained by this method can improve fuel economy effectively,and the equivalent fuel consumption per 100 km is reduced by 4.8%after optimization.
