试验工况驾驶行为评价方法

Evaluation Method for Driving Behaviors under Test Conditions

为了准确进行驾驶行为评价,根据SAE J2951底盘测功机测试驱动质量评估标准,引入测试循环能量变化率、测试循环距离变化率、测试循环单位能量变化率、试验循环的绝对速度变化率、测试循环速度的平方根误差、测试循环惯性做功变化率等评价指标对试验驾驶质量进行评价,通过两种不同驾驶行为下得到的计算结果,总结出一种试验工况驾驶行为评价方法。

In order to accurately evaluate driving behavior,according to the SAE J2951 chassis dynamometer test drive quality evaluation standard,the evaluation indicators of cycle energy change rate ER,cycle distance change rate DR,cycle specific energy change rate EER,cycle absolute speed change rate ASCR,cycle speed square root error RMSSE,and cycle inertia work change rate IWR are introduced to evaluate the test driving quality.The calculation results obtained under two different driving behaviors are analyzed,and a method for evaluating driving behavior under test conditions is summarized.
