文章采用加权因子法，提出了一种汽车动力传动系匹配的综合评价指标，它能从动力性、经济性和排放特性3个方面反映汽车的动力传动系合理匹配程度以及改善的潜力；给出了各参数因子的确定方法及权系数选取原则。利用整车性能仿真软件GT-DRIVE建立了某车型的仿真模型，通过仿真结果与实车性能数据对比，验证了模型建立的准确性。利用建立的仿真模型对3种不同的传动系匹配方案进行了仿真，并利用该评价指标对它们进行了对比评价，验证了该动力传动系综合评价指标的可靠性和实用性。

Based on the weighting factor method ,a comprehensive evaluation indicator of the vehicle powertrain matching is put forward .This indicator can reflect the quality of the powertrain system matching and the improving potential from three aspects ,i .e .power performance ,fuel economy and emission performance .The principles of determining weight coefficients and the methods of establis-hing parameter factors are described .Then a simulation model of a certain car is set up by using the vehicle performance simulation software GT-DRIVE ,and the accuracy of the model is proved by com-paring the simulation result with the performance data of the actual car .Finally ,three different pow-ertrain matching schemes are simulated by using the established simulation model and then evaluated by using the comprehensive indicator .The comparative analysis results show that this comprehensive evaluation indicator has high reliability and practicality .
