中国市场乘用车质量和动力性能参数特征

Characteristics of quality and power performance parameters of passenger cars(minibuses)in Chinese market

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可确定为整备质量为2 700 kg、满载质量为4 200 kg的纯电动轻客和整备质量为2 200 kg、满载质量为3 300 kg的燃油轻客;用于公路几何设计的设计车辆为比功率为20 W/kg的纯电动面包车和比功率为30 W/kg的燃油轻客。

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 3791 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%quantile values of the overall quality,full load quality,power and torque of passenger cars in China are 2040 kg,2600 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.The design vehicle for highway structure design can be determined as a pure electric light passenger with a total mass of 2700 kg and a full load mass of 4200 kg,and a fuel light passenger with a total mass of 2200 kg and a full load mass of 3300 kg.The design vehicle for highway geometric design can be identified as 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.
