摘要
为更精确、真实地测量汽车的燃料消耗量,采用滑行法进行试验。本文介绍了车辆道路行驶阻力的测量及数据处理方法,并将道路滑行阻力在转鼓上进行模拟计算,最终得到汽车在转鼓上的行驶阻力系数,并用于整车试验。
In order to obtain more accurate and real measurements of vehicle fuel consumption, the coastdown method is used to finish the test. The running resistance of vehicle in road measurement and data processing is introduced in this paper, and the road coastdown resistance is simulated on the Dyno. Finally, the running resistance coefficient of vehicle on the Dyno is obtained,which can be used for the vehicle test.
