摘要
针对EPS系统进行了四种试验工况的整车转向感觉主观评价试验,从轻便性、回正性、灵敏度、方向修正难易程度、转向精确程度、路感、侧倾感觉、疲劳程度等几个方面进行评价。应用多层次模糊方法建立了用于EPS转向感觉模糊评价的阶层化模型,综合考虑影响EPS转向感觉的各个方面,对模型做出综合的决策,从而获得系统全面的主观评价结果。
The vehicle steering feels of the electric power steering （EPS） system, including the maneuver ability of steering, the return ability of steering, the sensitivity of steering, the difficulty to correct the steering direction, the precision of steering, the road feel, the roll feel, and the tiredness by steering,etc. ,were evaluated subjectively under four test conditions. A hiarachic fuzzy evaluation model to evaluate the steering feels of the EPS system was established by the hiarachic fuzzy method. The comprehensive decision was incorporated in the model to consider the many-sided factors affecting the steering feels of the EPS system, and a systematic all-round subjective evaluation was obtained.
