摘　　要：汽车的动力性和燃油经济性是其最基本与最重要的性能之一。为在汽车开发之初分析整车的动力性和燃油经济性,文章研究了动力性和燃油经济性的评价指标,合理选取整车参数,利用GT-DRIVE软件对整车进行动力学和运动学建模与仿真计算。将仿真结果与试验结果对比,合理设置边界条件修正模型,最终得到较为精准的模型,使得在没有样车阶段,利用CT-DRIVE软件仿真可以得到整车的动力性和燃油经济性参数,能够对动力系统的匹配方案进行定量评价,为以后汽车的动力系统匹配优化提供一定的理论参考。Vehicle dynamic performance and fuel economy is one of the basie and important performances. In order to analyze wehicle dynamic pertbrmance and fuel economy at the beginning of the vehicle development, in this paper, the evaluating index for dynamic performance and fuel economy is studied and reasonably selecting vehicle parameters is introduced. Building vehicle dynamics model, kinematics model and simulation ealculation by using GT-DRIVE software is illustrated. Boundary conditions are set and a more accurate model finally is obtained hy the simulation results compared with the test results, the parameters for vehicle dynamic pelformance and fuel economy are gained using GT-DRIVE without a prototype, the quantitative analysis for power system matching is carried out, providing some reference for further power system optimization.
