摘要： 为了提高轻型载货汽车行驶工况油耗的测试精度，文章提出在不同载荷和道路类型条 件下进行构建行驶工况的研究思路。首先，构建测试系统以获取发动机电子控制单元（ECU）、 速度及行车轨迹、车身姿态和油耗量等信息。其次，基于合肥市及周边县、市道路选择包含 城区、城乡、山路和高速四种道路的试验路线。再次，进行道路试验和数据处理，分空载、 半载、75%载和满载进行道路试验，设计了包括油耗、车速分布和加速度分布等在内的 29 项 准则，利用短行程法和定步长法构建包含坡度和挡位信息的行驶工况。最后，经近百轮底盘 测功机试验验证和工况曲线调整，四种载荷的行驶工况综合油耗精度在 5%以内。因此，文章 提出的轻型载货汽车行驶工况研究方法可行，对同类商用车工况的研究具有一定的借鉴价值。

Abstract: To enhance the testing accuracy of fuel consumption for light-duty cargo vehicles under driving conditions, this article proposes a research approach to construct driving conditions under different loads and road types. Firstly, a test system is constructed to obtain information such as the engine electronic control unit (ECU), speed and driving trajectory, vehicle posture and fuel consumption rate. Secondly, based on the roads in Hefei city and its surrounding counties and cities, test routes covering urban areas, urban-rural areas, mountain roads and expressways are selected. Secondly, road tests and data processing are carried out. Road tests are conducted under no-load, half-load, 75% load and full load conditions. A total of 29 criteria, including fuel consumption,vehicle speed distribution and acceleration distribution, are designed. The driving conditions including slope and gear position information are constructed by using the short-stroke method and the fixed-step method. Finally, after nearly a hundred rounds of chassis dynamometer tests and adjustments to the operating condition curves, the comprehensive fuel consumption accuracy of the four loads under driving conditions is within 5%. Therefore, the research method for the driving conditions of light-duty cargo vehicles proposed in the article is feasible and has certain reference value for the research on the working conditions of similar commercial vehicles.
