Tire/road interaction plays an important role for safe operation of motor vehicles. The objective of this GOALI project is to establish a sensor-enabled modeling framework to real-time predict and preserve the safety limits of tire/road interaction. The project will develop, implement, and evaluate a safety-preserved tire/road interaction estimation and control scheme. The following three objectives will be pursued: (1) a sensor-enabled tire/road interaction modeling scheme; (2) a tire/road interaction safety-limit estimation and control system; and (3) technology implementation and transfer at Ford as well as research/education integration. The approach of this research is based on the integration of the physical and dynamic tire/road friction models with the distributed tire rubber deformation sensing system. Based on the sensor-enabled models, on-line estimation and control strategies will be developed to predict the safety limits of tire/road interaction and prevent vehicles from unsafe operation. The success of this project will advance fundamental understanding of tire/road interaction by providing new sensing mechanisms for modeling tire/road interaction, new knowledge and methodologies to real-time estimate the safety limits of tire/road interaction under normal driving conditions without the need of severe and unsafe maneuvers, and a new adaptive control methodology to preserve vehicle safety. Industrial implementation of the resulting methodology is expected to generate broad economic and societal impacts. One of the direct applications of the proposed research will be to advance the ?smart tire? technology in the automotive industry. The project will provide students (at the K-12, the undergraduate and graduate levels) with multidisciplinary training, exposure to important industrial problems, and practical experience.

轮胎与路面的相互作用对汽车的安全运行起着重要的作用。该GOALI项目的目标是建立一个传感器建模框架，以实时预测和保持轮胎/道路相互作用的安全极限。该项目将开发、实施和评估一种安全的轮胎/道路相互作用评估和控制方案。本项目的三个目标是：（1）传感器驱动的轮胎/道路相互作用建模方案;（2）轮胎/道路相互作用安全极限估计和控制系统;（3）福特的技术实施和转让以及研究/教育一体化。本研究的方法是基于集成的物理和动态轮胎/路面摩擦模型与分布式轮胎橡胶变形传感系统。基于传感器使能的模型，在线估计和控制策略将被开发，以预测轮胎/路面相互作用的安全极限，防止车辆不安全的操作。该项目的成功将通过提供用于建模轮胎/道路相互作用的新传感机制、用于在正常驾驶条件下实时估计轮胎/道路相互作用的安全极限的新知识和方法，而不需要严重和不安全的操纵，以及用于保护车辆安全的新自适应控制方法，来推进对轮胎/道路相互作用的基本理解。由此产生的方法的工业实施预计将产生广泛的经济和社会影响。拟议的研究的直接应用之一将是推进？智能轮胎？汽车行业的技术。该项目将为学生（在K-12，本科和研究生水平）提供多学科培训，接触重要的工业问题和实践经验。
