汽车驾驶循环反映了汽车运行所处“人－车－路”系统中对车辆性能有重要影响的因素。文中提出了一种运用特征参数对汽车驾驶循环进行研究的方法，分析了大量已有的和新提出的能反映驾驶循环特性的特征参数的物理意义和应用价值。提出了在强度指标、速度波动指标、工况概率指标等方面的重要的特征参数，并运用这些参数对国内外典型驾驶循环进行了比较。
The car driving cycle reflects the factors that have a significant impact on vehicle performance in the “car-car-road” system in which the car operates. In this paper, a method to study the driving cycle of vehicle is proposed by using the characteristic parameters, and a large number of existing and newly proposed physical parameters and their application values that can reflect the driving cycle characteristics are analyzed. The important characteristic parameters such as strength index, velocity fluctuation index and working probability index are put forward, and the typical driving cycles at home and abroad are compared by using these parameters.
