【摘要】 为实现汽车操纵稳定性主观评价客观化,以实车蛇行试验为例,研究汽车操稳性主观得分与客观测量数据之间的关系,建立相关性"最优"模型。结果表明,在小样本情况下,主观评价得分分别与平均转向盘转角无线性相关关系,与平均横摆角速度正线性相关关系,与平均车身侧倾角、平均侧向加速度负线性相关关系;平均横摆角速度对主观评价得分影响最显著,平均侧向加速次之,平均车身侧倾角最小。更多还原

【Abstract】 In order to achieve the objectification of the subjective evaluation of vehicle handling stability,taking the automotive snake test as an example,we studied the relationships between subjective scores and objective measurement dataof vehicle handling stability,and established the correlation optimal model. The results showed that,in the case of small samples,there was no linear correlation between the subjective evaluation scores and the average steering wheel angle,a positive linear correlation with average yaw rate, a negative linear correlation with mean lateral acceleration and vehicle body roll angle. In addition,the average yaw rate had the most significant effect on the subjective evaluation score,the average lateral acceleration followed,and the average body roll angle was the least significant.更多还原
