摘　　要：汽车传动系参数对整车的动力性和经济性有很大的影响。以驱动功率损失率和六工况百公里油耗量分别作为衡量汽车动力性和经济性的评价指标,采用动力性经济性统一目标函数建立汽车传动系参数优化模型,应用MAT-LAB软件优化工具箱中的优化计算函数来编制程序,最后对某样车的传动系参数进行优化,表明了优化设计的正确性与实用性。The parameters of automobile transmission can directly influence the power performance and the economy performance of the automobile. Based on the six conditions and the loss of driving power consumption of 100 km respectively as a measure of vehicle power and the economic evaluation, the optimization mathematical model of the parameters of automobile transmission with the power and economy performance united objective function is established, and the program is compiled by the function of optimization toolbox in MATLAB software. Finally, the transmission parameter of a prototype vehicle is optimized; the optimum design shows the correctness and practical.
