高速牵引车辅助驾驶节油算法研究

Research on fuel saving algorithm for assisted driving of high-speed tractors

为研究高速牵引车辅助驾驶的节油算法,以某款牵引车为研究对象,基于优秀驾驶员的驾驶行为分析,设计了牵引车在实际路谱中的预见性巡航控制策略,并使用整车仿真软件Cruise和建模软件Simulink进行联合仿真。结果表明:与定速巡航相比,在预见性巡航策略下每百公里燃油耗降低11.57%,实车测试时节油率为6.8%。

To study the fuel saving algorithm for assisted driving of high-speed tractors,taking a cer⁃tain tractor as the research object,based on the analysis of driving behavior of excellent drivers,a predic⁃tive cruise control strategy for the tractor in actual road spectra was designed.In addition,the vehicle simulation software Cruise and strategy modeling software Simulink were used for joint simulation.Results show that compared with cruise control,the fuel consumption is reduced by 11.57%per 100 kilometers under the predictive cruise control strategy,and the fuel saving rate during actual vehicle testing is 6.8%.
