Characteristics of quality and power performance parameters of passenger cars(minibuses)in Chinese market
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 pas-senger 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 over-all 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,respec-tively.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 2 700 kg and a full load mass of 4 200 kg,and a fuel light passenger with a total mass of 2 200 kg and a full load mass of 3 300 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.
