摘要:
在检测汽车超速行驶发生碰撞事故时,由于现场遗留痕迹难以鉴别其真伪,使得参数中容易存在假象证据的参数,参数敏感性分析的可信性需要进一步加强。为此,提出超速行驶下汽车追尾事故碰撞痕迹参数敏感性分析。依据汽车制动受力情况,构建事故再现模型,计算两车速度。在此基础上,基于模糊控制计算轮胎/路面附着系数,利用控制规则摒弃干扰参数,确定碰撞痕迹各项参数。针对痕迹参数的特点,利用微分描述参数灵敏度,完成参数敏感性分析。实验结果表明:设计的超速行驶下汽车追尾事故碰撞痕迹参数敏感性分析方法能量守恒稳定,并且不确定度较低,说明该方法的可信性得到了加强。
Abstract:
It is difficult to identify the authenticity of the traces left in the field, which makes the parameters easily contain false evidence. Therefore, the credibility of parameter sensitivity analysis needs to be further strengthened. Therefore, the sensitivity analysis of collision trace parameters in rear end collision accident under speeding is proposed. According to the braking force, the accident reappearance model is constructed to calculate the speed of two vehicles. On this basis, the adhesion coefficient of tire / road is calculated based on fuzzy control, and the parameters of collision trace are determined by using the control rules to discard the interference parameters. According to the characteristics of trace parameters, the sensitivity of parameters is described by differential, and the sensitivity analysis of parameters is completed. The experimental results show that the energy conservation and uncertainty of the proposed method are stable and the reliability of the method is enhanced.
