Analyzing the super??capacitor energy efficiency and the plug??in hybrid electric vehicle operating environment and electric mechanism, and adopting control variable method, two different kinds of allocation strategies are established by combining clutch and speed and judging charging states of the super??capacitor in hybrid drive on CD. Compared with the control strategy based on the average motor power, the fuel economy of the strategy fully on CD reaches the most efficiency, which rises by 3.15%. The trend curves of influence of each factor on the integrated fuel consumption are drawn with the optimization results of SA to guide to construct power allocation strategy for hybrid power system %K 复合电源 %K 4因子法 %K 模拟退火算法 %K 插电式混合动力汽车< %K br> %K hybrid power system %K method of four factors %K simulated annealing algorithm %K plug??in hybrid electric vehicle %U http://zkxb.xjtu.edu.cn/oa/DArticle.aspx?type=view&id=201507004
