摘　　要：影响驾驶员主观感觉的车辆运动量有很多,为研究驾驶员主观感觉与车辆客观运动量之间的关系,需要大量的试验样本,而在实际中往往很难实现。本文采用级别相当的两辆车,通过改变轮胎型号、胎压及配重质量等方法衍生出16种车型,完成相关的客观试验。利用主成分分析方法,对所提出的客观指标做降维处理,从而降低主、客观一致性研究对试验样本量的要求,为主客观评价体系的一致性研究打下了基础。There are many vehicle motions that affect driver＇s subjective feeling. A lot of test samples are needed to study the relationship between driver＇s subjective feeling and objective motion of vehicles, however this is difficult to do so in reality. By changing tire model, tire pressure and balance weight mass of two vehicles of appropriate class, 16 models are derived and corresponding objective tests are implemented. With main component analysis methods, dimensional reduction is made to the proposed objective criteria, thus the requirement of subjective and objective consistency study on amount of test samples is lowered down, laying foundation for consistency study of the subjective and objective evaluation system.
