Abstract

Our paper introduces new reconstruction techniques of real-life critical road traffic accidents focusing on highly automated functions. The investigation method presented here focuses on the effect of relevant control parameters and environmental factors following the concept of sensitivity analysis. Two reconstruction tools are applied, the choice depending on the relevant causal factor of the accidents. Our measurement proves that the technical parameters of the control process, like time to collision or braking pressure that affects user satisfaction directly, can significantly influence the probability of accident occurrence. Thus, it is reasonable to consider safety with an increased weight compared to the user experience when identifying these parameters’ values. On the other hand, the effects of the investigated environmental factors were also found to be significant. Accordingly, future ADAS applications need to consider the change of environmental factors in the case of increased risk level, and driver-mode should be adapted to the new situation.

关键情况下自动车辆功能的建模与仿真——一种新的事故重建概念的应用

本文以高度自动化的功能为重点，介绍了现实生活中关键道路交通事故的新重建技术。本文提出的调查方法遵循敏感性分析的概念，关注相关控制参数和环境因素的影响。应用了两种重建工具，选择取决于事故的相关因果因素。我们的测量证明，控制过程的技术参数，如碰撞时间或制动压力，直接影响用户满意度，可以显著影响事故发生的概率。因此，在确定这些参数值时，与用户体验相比，考虑安全性增加权重是合理的。另一方面，所调查的环境因素的影响也很显著。因此，未来的ADAS应用需要考虑在风险水平增加的情况下环境因素的变化，驾驶模式需要适应新的情况。
