Ride quality, active safety and energy efficiency of convoy vehicles will be improved through the use of preview-controlled active suspensions. Both ride quality and roadholding of actively-suspended vehicles (i.e., with a force actuator in the suspension system) can be improved by sensing the road ahead of the vehicle and using this information in a preview controller. Instead of vulnerable look-ahead sensors mounted on the front bumper of the vehicle, the overall response of the preceding vehicle(s) is proposed as a means to generate preview controller information for followers. In our proposed research controllers will be designed and simulated to assess performance, stability and robustness. Physical implementation will be done using reduced-scale vehicle hardware. Active suspensions also reduce the longitudinal energy lost to vertical suspension motion, thereby potentially reducing vehicle energy consumption. The reduction for vehicles with preview-active suspension and intelligent cruise control will be quantified through simulation. The use of lead-vehicle-as-sensor will then be applied to yaw and roll dynamics to improve handling and ride quality during cornering. Contributions to the research community include novel control schemes, robust estimators of difficult-to-measure vehicle states, and insight into energy interactions among vehicle system elements. This research is important to the military, which deploys trucks in closely-spaced convoys where the terrain can be highly variable and the drivers young and inexperienced. Ride quality improvements reduce fatigue and injury, while roadholding improvements increase maneuverability and stability. Fuel savings are important for efficient military deployments. Fuel consumption and emissions are major concerns associated with heavy trucks, and widespread environmental and economic benefits will result from their reduction. Improved vehicle-to-vehicle communication could eventually allow communication of lead-vehicle-as-preview information to warn followers of road obstacles, thereby benefiting not only convoy vehicles, but also the general driving public.

车队车辆的行驶质量、主动安全性和能源效率将通过使用预瞄控制主动悬架得到改善。 主动悬挂车辆的行驶质量和抓地性能（即，在悬架系统中具有力致动器）可以通过感测车辆前方的道路并在预瞄控制器中使用该信息来改进。 代替安装在车辆前保险杠上的易受攻击的前瞻传感器，提出了前车的整体响应作为为跟随者生成预览控制器信息的手段。 在我们提出的研究控制器的设计和仿真，以评估性能，稳定性和鲁棒性。 物理实现将使用缩小规模的车辆硬件完成。 主动悬架还减少了纵向能量损失到垂直悬架运动，从而潜在地减少了车辆能量消耗。通过模拟，将对配备预瞄主动悬架和智能巡航控制系统的车辆的减排量进行量化。 然后，将引导车辆作为传感器的使用应用于偏航和侧倾动力学，以改善转弯过程中的操纵性和行驶质量。 对研究界的贡献包括新颖的控制方案，难以测量的车辆状态的鲁棒估计，并深入了解车辆系统元素之间的能量相互作用。 这项研究对军方很重要，因为军方将卡车部署在距离很近的车队中，这些车队的地形变化很大，司机年轻且缺乏经验。行驶质量的改进减少了疲劳和伤害，而抓地性能的改进提高了机动性和稳定性。 节省燃料对有效的军事部署很重要。 燃料消耗和排放是与重型卡车相关的主要问题，减少燃料消耗和排放将带来广泛的环境和经济效益。 改进的车辆间通信最终可以允许前导车辆作为预览信息的通信，以警告跟随者道路障碍物，从而不仅使车队车辆受益，而且使一般驾驶公众受益。
