DRIVE: Dynamic Rule Inference and Verified Evaluation for Constraint-Aware Autonomous Driving
- 从专家驾驶数据中动态推断软约束规则
- 实现0%软约束违规,轨迹更平滑且泛化能力强
- 适合需要安全合规的自动驾驶系统研发
理解并遵守软性交通约束是实现安全、符合社会规范的自动驾驶的关键。然而,这些约束往往隐含、依赖上下文且难以显式定义。本文提出DRIVE框架,通过指数族似然建模估计状态转移的可行性,构建随驾驶场景变化的概率化行为规则表示。学习到的规则分布被嵌入基于凸优化的规划模块,生成不仅动态可行且符合人类偏好的轨迹。与依赖固定约束形式或纯奖励建模的方法不同,DRIVE实现了规则推断与轨迹决策的紧密耦合,支持数据驱动的约束泛化与可验证的可行性分析。在inD、highD和RoundD等大规模自然驾驶数据集上验证,DRIVE实现0%软约束违规率,轨迹更平滑,跨场景泛化能力更强。验证评估进一步证明该框架在实际部署中的高效性、可解释性与鲁棒性。
原文摘要 · Abstract (English)
Understanding and adhering to soft constraints is essential for safe and socially compliant autonomous driving. However, such constraints are often implicit, context-dependent, and difficult to specify explicitly. In this work, we present DRIVE, a novel framework for Dynamic Rule Inference and Verified Evaluation that models and evaluates human-like driving constraints from expert demonstrations. DRIVE leverages exponential-family likelihood modeling to estimate the feasibility of state transitions, constructing a probabilistic representation of soft behavioral rules that vary across driving contexts. These learned rule distributions are then embedded into a convex optimization-based planning module, enabling the generation of trajectories that are not only dynamically feasible but also compliant with inferred human preferences. Unlike prior approaches that rely on fixed constraint forms or purely reward-based modeling, DRIVE offers a unified framework that tightly couples rule inference with trajectory-level decision-making. It supports both data-driven constraint generalization and principled feasibility verification. We validate DRIVE on large-scale naturalistic driving datasets, including inD, highD, and RoundD, and benchmark it against representative inverse constraint learning and planning baselines. Experimental results show that DRIVE achieves 0.0% soft constraint violation rates, smoother trajectories, and stronger generalization across diverse driving scenarios. Verified evaluations further demonstrate the efficiency, explanability, and robustness of the framework for real-world deployment.
