摘要：为掌握我国乘用车质量和动力性能参数的分布特征，对3 791辆乘用车的5种细分车型和能源形式进行了质量和动力性能差异性的分析，确定了小客车专用公路设计车辆的质量和性能参数建议值。结果表明：我国乘用车的整备质量、满载质量、功率、扭矩的第85%分位值分别为2 040 kg、2 600 kg、180 kw、370 n m。纯电动车整备质量和满载质量的平均值均大于燃油汽车的平均值。纯电动车中suv比功率最大、面包车比功率最小，燃油汽车中suv比功率最大、轻客比功率最小。小客车专用公路中，用于公路结构设计的设计车辆为纯电动轻客整备质量取2 700 kg，满载质量取4 200 kg，燃油轻客整备质量取2 200 kg，满载质量取3 300 kg；用于公路几何设计的设计车辆为纯电动面包车比功率取20 w/kg，燃油轻客比功率取30 w/kg。

characteristics of quality and power performance parameters of passenger cars (minibuses) in chinese market
abstract：in order to get the distribution characteristics of the quality and power performance parameters of passenger vehicles in china, five types and energy forms of 3 791 passenger vehicles were analyzed with emphasis on the differences of quality and dynamic performance, and the recommended values of quality and performance parameters of special highway design vehicles for passenger vehicles were determined. by analyzing the differences of 3791 different passenger cars, pure electric vehicles and fuel vehicles, the road design vehicles for small passenger cars are determined. the results show that the 85 th quantile values of the overall quality, full load quality, power and torque of passenger cars in china are 2 040 kg, 2 600 kg, 180 kw and 370 n m, respectively. the average value of the total mass and full load mass of the pure electric vehicle is greater than that of the fuel vehicle. the maximum specific power of the suv in the pure electric vehicle is the smallest, and the maximum specific power of the suv in the fuel vehicle is the smallest. in the special highway for small passenger cars, the vehicles for highway structure design are as follows : the pure electric light passenger has a mass of 2700 kg and a full load mass of 4 200 kg, and the fuel light passenger has a mass of 2 200 kg and a full load mass of 3 300 kg. the total masses of ordinary passenger cars and multi-purpose passenger cars are 2 550 kg and 4 222 kg, repsectively. the design vehicle for highway geometric design is a pure electric van with a specific power of 20 w/kg and a fuel light passenger with a specific power of 30 w/kg.
