摘　　要：本文研究了在长时间驾驶过程中进行姿势调节(包括坐垫调节和靠背调节)的效果,综合采用了体压分布测试手段和主观评价方法,研究了调节方向、调节幅度和调节频度的影响。坐垫调节实验和靠背调节实验的结果表明,向前调整坐垫能显著提高驾乘舒适性,尤其是手臂、下肢等末端的舒适性;向后调整坐垫效果不明显。向前调整靠背能够在整体上提高人体舒适性,但是臀部的舒适性会下降;向后调整靠背效果不大。就本文中选取的调节幅度和频度,对坐垫调节效果和靠背调节效果没有显著的影响。The effects of posture adjustment, including seat cushion adjustment and backrest adjustment, during longtime driving are studied in this paper. Specifically, the effects of the direction, amplitude and frequency of adjustment are studied by comprehensively adopting the testing means of body pressure distribution and subjective rating method. The results of seat cushion and backrest adjustment experiments indicate that the forward adjustment of seat cushion can significantly enhance driving comfort, especially the comforts of hands and legs;while the backward one has no apparent effects. The forward adjustment of backrest can also improve the comfort of overall human body except hip;while the backward one has little effects. As for the amplitude and frequency of adjustment, their changes on the effects of both seat cushion and backrest adjustments are not significant.
