AMT自动换挡车辆行驶环境的模糊融合

Fuzzy Synthesis of AMT Vehicles Traffic Environment

对车辆行驶环境进行了分析,研究了车辆在各种环境下的换挡特性,重点研究了路面阻力、转弯大小以及坡度大小对车辆换挡的影响,进而利用模糊推理技术对车辆行驶环境的模糊融合,其结果用于在车辆自动换挡时对换挡规律的选择和修正。本文是在仿真环境下模拟车辆行驶环境,根据试验数据和驾驶员换挡经验,建立了输入输出模糊化子集,并制定了模糊推理规则库,最后建立了一个三输入单输出模糊推理系统。

In the paper, traffic environment is analyzed, and shift characteristic of vehicles is researched, especially the effect of resistance, turning radius, and slope size on vehicles transmission shift, then fuzzy fusion of traffic environment is done with fuzzy inference. Finally the conclusion is applied to chose and modify vehicles transmission shift rules. The vehicle is simulated in laboratory conditions. According to experimental data and driver＇ s experience of shift, input and output fuzzy subsets and fuzzy rule base are constituted. Finally a three-input single-output Fuzzy Inference system is established.
