摘要: 针对自动驾驶决策规划中动态环境交互与复杂行为预测的核心挑战,提出一种融合交互预测信息的自动驾驶安全规划方法。首先,构建图注意力网络(Graph attention network,GAT)提取智能体动态交互特征,并设计图卷积网络(Graph convolutional network,GCN)聚合车道拓扑交互特征。其次,联合前述交互特征以及自车规划特征,解码出自车运动影响下的周围车辆未来行驶轨迹。进一步,基于模型预测控制(Model predictive control,MPC)框架,通过预测时域维度对齐的方式融合预测信息,构建全局系统状态表征。同时设计目标函数以及约束条件保证车辆动作的最优化求解。实验环节基于真实驾驶轨迹数据集INTERACTION以及CARLA仿真平台进行验证。实验结果表明该方法在预测准确性、规划安全性以及通行效率等关键指标上均优于对比模型,尤其在交互密集型场景中展现出更强的意图推理能力。本研究为复杂动态交通场景下的自动驾驶安全规划提供了具有可解释性的解决方案。

Abstract: This paper addresses the core challenges of dynamic environmental interaction and complex behavior prediction in autonomous driving decision planning by proposing a safety planning method that integrates interaction prediction information. First, a graph attention network(GAT) is constructed to extract dynamic interaction features of agents, while a graph convolutional network (GCN) is designed to aggregate lane topology interaction features. Subsequently, by combining these interaction features with the vehicle's own planning features, the future trajectories of surrounding vehicles under the influence of the vehicle's own motion are decoded. Furthermore, within a model predictive control(MPC) framework, the method integrates predictive information through time-domain alignment to construct a global system state representation. A objective function and constraints are designed to ensure optimal vehicle action solutions. Experiments validate the approach using the real-world driving trajectory dataset INTERACTION and the CARLA simulation platform. Experimental results demonstrate that this method outperforms comparison models in key metrics such as prediction accuracy, planning safety, and traffic efficiency, particularly exhibiting stronger intent inference capabilities in interaction-dense scenarios. This research provides an interpretable solution for safe autonomous driving planning in complex dynamic traffic environments.
