摘　　要：对于汽车燃油经济性的评价,依赖于准确的道路行驶工况。该文以合肥市为例,针对城市复杂分级道路、交通流和驾驶习惯,研究一种道路行驶工况制定方法。基于控制器局域网(CAN)总线,构建了道路工况测试系统。将合肥市道路分为快速路、主干道、次干道、支路4级,综合考虑天气、空调使用、出行时间段、节假日等因素,进行了道路试验。所制定的道路行驶工况包括挡位和坡度信息并经过转毂台架试验验证和优化。结果表明:用该文制定的道路行驶工况进行转毂台架试验油耗与实际道路试验油耗偏差稳定在2%以内。因此,该文提出的方法是有效可行的。The evaluation to fuel economy, which is an important vehicle performance, depends on driving cycle. A method for road driving cycle was developed considering urban complicated classified road, traffic flow, driving habit with taking Hefei city as an example. A driving cycle test system was constructed based on the CAN（controller area network） bus. The urban road was classified into express road, main road, subsidiary road, by-pass road, etc., and some tests were conducted considering the weather, the using of air-conditioner, the test time phase, holidays or weekend, etc. A driving cycle including the shift and the road slope information was developed, verified and optimized by drum dynamometer tests. The results show that the deviation is less than 2% steadily for the fuel consumption between the drum dynamometer tests using the developed driving cycle and the road way tests. Therefore, it proves this cycle develop method is effective and feasible.
