摘要:

本研究强调了智能驾驶功能在提升道路安全和驾驶舒适性方面的重要性。我们研究的核心挑战在于获取足够多的测试数据来评估这些功能,尤其是在高风险、安全关键的驾驶场景中。此类场景往往面临数据匮乏的问题,这主要是由于其固有的复杂性和所涉及的风险所致。为弥补这一不足,我们的研究提出了一种新颖的方法论,旨在生成一系列多样化且逼真的安全关键驾驶场景。该方法显著拓宽了驾驶员辅助系统和自动驾驶车辆功能的测试范围。我们特别关注跟车行驶场景,因为它在实际应用中具有高度相关性。在此场景中,车辆运动通过运动学方程进行精细建模,并纳入驾驶员反应时间等因素。我们通过改变参数来生成一系列合理的驾驶场景。利用差空间停车(DSS)指标是我们研究中的关键要素。该指标在跟车行驶的安全评估中发挥着至关重要的作用,有助于实现更全面、更彻底的验证过程。通过这种方式,我们的方法论增强了驾驶员辅助和自动驾驶系统的可靠性与安全性评估,特别是针对最具挑战性和安全关键的场景进行了定制优化。

英文摘要:

This study underscores the vital importance of intelligent driving functions in enhancing road safety and driving comfort. Central to our research is the challenge of obtaining sufficient test data for evaluating these functions, especially in high-risk, safety-critical driving scenarios. Such scenarios often suffer from a dearth of available data, primarily due to their inherent complexity and the risks involved. Addressing this gap, our research introduces a novel methodology designed to create a wide array of diverse and realistic safety-critical driving scenarios. This approach significantly broadens the testing spectrum for driver assistance systems and autonomous vehicle functions. We particularly focus on the follow-up drive scenario due to its high relevance in practical applications. Here, vehicle movements are intricately modeled using kinematic equations, incorporating factors like driver reaction times. We vary parameters to generate a spectrum of plausible driving scenarios. The utilization of the Difference Space Stopping (DSS) metric is a pivotal element in our research. This metric plays a crucial role in the safety evaluation of follow-up drives, facilitating a more thorough and comprehensive validation process. By doing so, our methodology enhances the reliability and safety assessment of driver assistance and autonomous driving systems, specifically tailored for the most challenging and safety-critical scenarios.
