摘要

针对一辆城市客车和一辆非城市货车进行了Pems试验，对比了Pems试验工况与中国工况的速度分布、加速度分布。结果表明：Pems客车试验工况中，速度分布存在4个峰值区间，加速度分布存在2个峰值区间；CHTC-B工况中，速度分布存在1个峰值区间，加速度分布存在1个峰值区间。Pems货车试验工况中，速度分布存在4个峰值区间，加速度分布存在2个峰值区间；CHTC-HT工况中，速度分布存在1个峰值区间，加速度分布存在3个峰值区间。对比功率计算式的系数进行了标定，并对比了Pems试验工况和中国工况的比功率分布。结果表明，在比功率［-2.7,2.7］区间内，Pems客车试验工况比功率分布为双峰曲线，CHTC-B工况为单峰曲线；Pems货车试验工况比功率分布为双峰曲线，CHTC-HT工况为单峰曲线。

Abstract

Pems tests of city-permitted bus and cityforbidden heavy-duty truck were conducted respectively. Vehicle velocity distribution and acceleration distribution of Pems tests and China heavyduty commercial vehicle test cycles were then compared. The results show that there are 4 peak intervals for velocity distribution and 2 peak intervals for acceleration distribution in the Pems test of bus, compared with 1 peak interval for velocity and acceleration distribution respectively in the CHTC-B cycle. For the truck, the velocity and acceleration distributions show 4 and 2 peak intervals in the Pems test and 1 and 3 peak intervals in the CHTC-HT cycle. Coefficients of the formula used to calculate vehicle specific power are calibrated. Vehicle specific power distribution of Pems tests is further compared to that of China heavyduty commercial vehicle test cycle. According to the results, the vehicle specific power distribution curves have double peaks in the Pems test and one peak in the CHTC-B cycle and CHTC-HT cycle for both bus and heavyduty truck between -2.7 kW/t and 2.7 kW/t.
