摘要: 随着通信技术及自动化控制技术的发展,智能网联汽车的自主控制方法,特别是混合编队下的控制方法已经成为无人驾驶技术研究的重要方向。由于车载处理器计算能力有限,为了减少控制策略输出的时延,提高车辆跟踪效果,提出了基于边缘智能的车辆编队协同控制方法。利用边缘服务器的强大计算能力和5G通信网络,设计了基于边缘智能的控制系统,将计算任务上传至云端,充分释放车载处理器的计算资源。对混合编队下的跟车场景进行了分析,设计了时空耦合场景下的车辆编队控制模型,利用MPC控制算法,建立了车辆动力学模型,通过模型预测、滚动优化与反馈校正为智能网联汽车提供控制策略计算服务。经MATLAB仿真实验及边缘计算虚拟平台实验验证,所提出的MPC控制算法在轨迹跟踪控制上表现良好,能够实时高效地为车辆提供安全控制策略。
