提出了一种改进城市公交循环工况的开发方法.根据车流量在主要商业区、工业区与居民区之间选择测试线路进行数据采集,以公交各站点间的行程作为短行程,根据工况时间比例由短行程构建城市公交循环工况,用参数均值方差选择典型城市公交循环工况.以大连城市公交为例,验证了改进的城市公交循环工况开发方法的有效性,以及应用该方法合成的大连城市公交循环工况的真实性.为开发适合城市公交特点的电动汽车,及其污染物排放量和燃油消耗量的测量提供了设计依据.
An improved method is developed for urban bus driving cycle construction.Driving condition data are collected on the representative routes which are selected between the major residential areas and commercial or industrial areas according to the traffic flow.The micro-trip is defined as a trip between two bus stops.A driving cycle is then constructed with the randomly selected micro-trips according to the proportion of the driving condition.The representative urban bus driving cycle is selected by the varia...
