摘要:

建立严格的验证和确认(V&V)流程,以在高度自动化车辆(HAV)在公共道路上广泛部署之前评估其安全性非常重要。在本文中,我们提出了一个互动意识的框架HAV安全评估,这是适合于一些高度互动的驾驶场景,包括高速公路合并,环形交叉口进入等现有的方法相反,主要的其他车辆(ESTA)采取预定的机动,我们建模ESTA作为一个博弈论代理。为了捕捉各种各样的互动之间的测试和车辆测试(VUT),我们的互动行为的特点,使用水平k博弈论和社会价值取向和训练不同的一组使用强化学习的POVs。此外,我们提出了一个自适应的测试用例抽样方案的基础上高斯过程回归技术,以产生定制的和多样化的挑战性的情况下。高速公路合并被用作示例场景。我们发现所提出的方法是能够捕捉到广泛的故障行为,并实现更好的覆盖率的VUT的故障模式相比,其他评估方法。

英文摘要:

It is important to build a rigorous verification and validation (V&V) process to evaluate the safety of highly automated vehicles (HAVs) before their wide deployment on public roads. In this paper, we propose an interaction-aware framework for HAV safety evaluation which is suitable for some highly-interactive driving scenarios including highway merging, roundabout entering, etc. Contrary to existing approaches where the primary other vehicle (POV) takes predetermined maneuvers, we model the POV as a game-theoretic agent. To capture a wide variety of interactions between the POV and the vehicle under test (VUT), we characterize the interactive behavior using level-k game theory and social value orientation and train a diverse set of POVs using reinforcement learning. Moreover, we propose an adaptive test case sampling scheme based on the Gaussian process regression technique to generate customized and diverse challenging cases. The highway merging is used as the example scenario. We found the proposed method is able to capture a wide range of POV behaviors and achieve better coverage of the failure modes of the VUT compared with other evaluation approaches.
