摘　　要：为了提高乘用车操纵稳定性评价的准确性和客观性,参考国家相关标准,分别从稳态回转性、转向回正性、转向轻便性、抗侧倾能力、抗干扰能力和瞬态响应性6个方面筛选15个评价指标。根据各指标对乘用车操纵稳定性的实际影响程度,确定了各指标的权重。以实车试验获得的指标参数为实例,采用基于灰色关联分析的方法,对试验汽车进行操纵稳定性评价。对比国标法评价结果,并参考驾驶员主观评价,证明了运用灰色关联法进行乘用车操纵稳定性评价的可行性。In order to improve the accuracy and objectivity of passenger car handling stability evaluation,15 evaluating indexes were selectedfrom 6 aspects of steady state rotation,steering return,steering light,anti-roll ability,anti-interference ability and transient response respectively referring to the national standard.The weight of each index is determined according to the actual influence on the handling stability. Taking the parameters obtained by real car test as an example,the handling stability evaluation is carried out based on the method of grey correlation analysis. The feasibility ofusing grey correlation method to evaluate the passenger carhandling stability is proved by comparing the results of the national standard method and the subjective evaluation of the drivers.
