摘要:
共享汽车具有车型统一、用户多变且使用频率高的特点,为提升共享汽车使用效率和驾乘体验,研发一种能根据驾驶员特征自动调节舒适坐姿的智能座椅意义重大。本文针对用户座椅调节存在的主观任意性导致的座椅舒适性问题 ,结合共享汽车智能座椅项目,以座椅H点前后位置、H点高低位置、坐垫角和靠背角4个变量为研究因子进行台架实验,分别研究5th、50th和95th百分位驾驶员的座椅舒适性受座椅参数的影响规律。首先,每个研究因子在参考车型范围内均匀选取3个实验水平,采用正交实验表对实验次数进行简化,确定正交实验须进行的组数并进行正交台架实验。实验人员对每组的座椅舒适性进行主观评价,同时通过压力测量仪和数显角度尺测量实验人员的体压分布信息和关节角度信息;其次,通过聚类分析确定了本文采用的以关节角度为客观参数的主客观舒适性评价体系,通过正交实验分析,得出了不同座椅参数对座椅舒适性的影响存在差异的结论,且随着驾驶员百分位的变化,对座椅舒适性造成影响的参数也在发生变化;最后,对正交实验所得数据进行修正拟合,构建了座椅适宜H点位置预测模型和靠背角度预测模型。
