在这项工作中，我们整合了重型车辆纵向控制的两个曾经独立的概念：使用预览响应高程变化以提高燃油经济性，并使用反馈对前面车辆的运动做出反应。这两个概念是统一的，为重型车辆提供安全而节能的连接和自动化技术。首先，基于势垒函数理论建立了两个概念的集成控制框架，然后讨论了每个概念的详细控制设计。最后，我们通过实验评估连接自动卡车的性能，证明了所提出的设计对朴素切换控制器的好处。
In this work, we integrate two once separate concepts for longitudinal control of heavy duty vehicles: responding to elevation changes to improve fuel economy using preview and reacting to the motion of preceding vehicles using feedback. The two concepts are unified to provide a safe yet fuel efficient connected and automated technology for heavy duty vehicles. First, we establish an integrated control framework of the two concepts based on barrier function theory and then we discuss the detailed control design of each concept. Finally, we demonstrate the benefits of the proposed design against a naive switching controller by experimentally evaluating the performance of a connected automated truck.
