摘要
详细地论述了城市客车循环工况开发的程序和测试方法,并通过自行设计的测试仪器和数据采集系统,完成了北京城市客车循环工况的测量。详细分析了北京公交客车的实际运行特点,得出了北京城市客车的平均车速、运行时间、停车时间、加减速度以及客流量服从正态分布。同时,分析了变速器挡位分布。基于城市工况的特征,提出了一种多条线路循环工况的合成方法。结果表明,所开发的北京城市循环工况能够反映北京城市公交客车的实际运行状况,具有实用价值。
The development procedure and testing method of driving cycle for public buses are discussed in detail and the measurement of driving cycle for public buses in Beijing city is conducted by using self-designed instruments and data collection system. The operation characteristics of Beijing public buses are thoroughly analyzed based on statistics probability distribution theory, which show that the average speed, operation time, stopping time, acceleration and deceleration, as well as passenger flow all present the pattern of normal distribution. In addition, the distribution of different gears used is also analyzed. The results show that the developed Beijing driving cycle can reflect the actual operation state for public buses in Beijing.
