摘　　要：利用GPS对北京市乘用车、公交车和重型卡车进行实际道路工况数据采集,并进行了工况解析,提取了北京市典型行驶工况。结果表明,乘用车和公交车由于多运行于市区,车辆运行速度较低,怠速、加减速比例较高。重型卡车由于白天只能在五环外运行,匀速运行比例和平均速度均较高。与国外工况相比,北京市的轻重型卡车在平均速度、加速度和减速度、工况行驶比例均有比较大的偏差。Measurement of driving cycle and data collection were performed using a GPS system for light-duty vehicles, buses and heavy-duty trucks separately. Based on the driving data collected, the cycle analysis was conducted and typical cycles in Beijing were developed. The results showed that light duty vehicles and buses ran mostly in urban areas at low speed mode, and the proportions of idle, acceleration and deceleration were very high. Heavy duty trucks could run only outside the Fifth Ring Road in the daytime at higher speed mode and there was a higher proportion of uniform speed mode. Compared with driving modes in foreign countries, there was large disparity in average vehicle speed, acceleration, deceleration and ratio of different modes for the heavy-duty trucks in Beijing.
