The assessment of vehicle dynamic comfort to human body vibration varies from person to person. Even though the dynamic comfort rating can be obtained by placing measurement devices over the cabin, passengers may have dissimilar sensations. For many car manufacturers, both subject and objective measurements are used together at development of new cars. To effectively assess the dynamic comfort of vehicle, this research explores the correlation between the objective measurement of the whole body vibration, hand-transmitted vibration and subjective assessment. The whole body vibration is measured from the backrest, seat surface and vehicle floor, whereas the hand-transmitted vibration is measured from the steering wheel. Four different vehicles are driven at various speeds on five types of pavements. Both simple linear regression and polynomial regression models based on Stevens’s power law from psychophysics are built to correlate the subjective and objective data. The regression results show that (1) the seat surface is more reliable than other positions for assessing the human body vibration; (2) the hand transmitted vibration on rough roads is more trustful for dynamic comfort evaluation than on smooth roads; (3) the overall dynamic comfort value is the most reliable index for dynamic comfort evaluation.

车辆对人体振动的动态舒适性评估因人而异。即使可以通过将测量设备放在机舱上方来获得动态舒适度等级，但乘客可能会有不同的感觉。对于许多汽车制造商而言，在开发新车时会同时使用主题和客观测量。为了有效地评估车辆的动态舒适性，本研究探索了全身振动的客观测量，手传递振动和主观评估之间的相关性。从靠背，座椅表面和车辆地板测量整个身体的振动，而从方向盘测量手传递的振动。在五种类型的人行道上，四种不同的车辆以不同的速度行驶。建立基于心理物理学史蒂文斯幂定律的简单线性回归和多项式回归模型，以关联主观和客观数据。回归结果表明：（1）座椅表面在评估人体振动方面比其他位置更可靠；（2）在崎rough不平的道路上，手传递的振动比平整在道路上对动态舒适性的评估更可靠；（3）总的动态舒适度值是评估动态舒适度最可靠的指标。（2）在崎rough不平的道路上，手传递的振动比平整在道路上对动态舒适性的评估更可靠；（3）整体动态舒适度值是评估动态舒适度最可靠的指标。（2）在崎rough不平的道路上，手传递的振动比平整在道路上对动态舒适性的评估更可靠；（3）整体动态舒适度值是评估动态舒适度最可靠的指标。
