用类人行人模型生成更真实的对抗性场景,优化自动驾驶控制器。

Realistic adversarial scenario generation via human-like pedestrian model for autonomous vehicle control parameter optimisation

  • 基于认知启发的类人行人模型,模拟个体间与个体内的行为差异。
  • 生成的场景使车辆减速更平滑,间隙接受行为更真实,减少过度保守。
  • 适合自动驾驶安全测试与控制器优化,提升仿真可信度。

自动驾驶汽车(AV)正快速发展,其安全部署需可靠地与行人等道路使用者交互。直接在公共道路上测试成本高且危险,尤其对罕见但关键的交互场景。因此,仿真测试成为实用替代方案。当前广泛使用的对抗性场景多追求难度而忽视真实性,导致行为夸张,使控制器过于保守。本文提出一种新方法:采用具有个体间和个体内变异性的认知启发式行人模型,生成行为上合理的对抗性场景。通过闭环测试与调优,验证了该方法在优化AV控制器方面的潜力。结果表明,用类人模型替代CARLA中的规则型行人后,车辆的间隙接受模式更真实,减速过程更平滑。不安全交互仅出现在特定行人个体与条件下,凸显了人类行为变异性的重要性。此类场景可用于优化AV控制器,实现更安全高效的行驶行为。本研究展示了将类人道路使用者模型融入仿真对抗测试,可提升自动驾驶评估的可信度,并为行为导向的控制器优化提供实际基础。

原文摘要 · Abstract (English)

Autonomous vehicles (AVs) are rapidly advancing and are expected to play a central role in future mobility. Ensuring their safe deployment requires reliable interaction with other road users, not least pedestrians. Direct testing on public roads is costly and unsafe for rare but critical interactions, making simulation a practical alternative. Within simulation-based testing, adversarial scenarios are widely used to probe safety limits, but many prioritise difficulty over realism, producing exaggerated behaviours which may result in AV controllers that are overly conservative. We propose an alternative method, instead using a cognitively inspired pedestrian model featuring both inter-individual and intra-individual variability to generate behaviourally plausible adversarial scenarios. We provide a proof of concept demonstration of this method's potential for AV control optimisation, in closed-loop testing and tuning of an AV controller. Our results show that replacing the rule-based CARLA pedestrian with the human-like model yields more realistic gap acceptance patterns and smoother vehicle decelerations. Unsafe interactions occur only for certain pedestrian individuals and conditions, underscoring the importance of human variability in AV testing. Adversarial scenarios generated by this model can be used to optimise AV control towards safer and more efficient behaviour. Overall, this work illustrates how incorporating human-like road user models into simulation-based adversarial testing can enhance the credibility of AV evaluation and provide a practical basis to behaviourally informed controller optimisation.
