摘要:
本文提出了一种考虑预测风险的自动驾驶车辆运动规划方法,该方法基于模型预测控制算法,同时融合了周围车辆未来轨迹的交互预测及其风险。首先,将车与车之间的交互建模成图结构,建立感知交互的运动预测模型;其次,训练多个同构异参的预测模型,利用集成技术来获得预测网络对于预测结果的不确定性风险;然后,基于获得的预测算法不确定性风险,利用模型预测控制算法来处理风险,通过在优化问题约束中综合考虑安全约束、车辆物理属性约束等,设计了考虑预测不确定性风险的自动驾驶运动规划方法;最后,基于真实驾驶数据集数据和SUMO仿真平台,对建立的预测模型的运动预测能力、基于模型预测控制的运动规划方法的有效性以及运动规划处理预测风险的能力进行了验证。仿真结果表明,在面对周围车辆的紧急加减速等预测风险较高的场景时,本文提出的运动规划方法能够感知到预测算法的不确定性风险并采取动作来规避风险,可提升道路驾驶安全性。
