简介: |
Pneumatic tires and rubber wheels are critical components in mobile systems such as vehicles and ground robots that are widely used for passenger and goods transportation. The tire/road interactions in these systems play an extremely important role for not only system design but also safe operation. In this talk, I will first present two different modeling schemes for on-line estimation of the tire/road friction coefficient and braking control for automated vehicles. I will then present the development of a tire rubber deformation sensing system for enhancing real-time tire/road friction estimation. An analytical sensing output model that is used to capture the tire/road friction characteristics will be presented. The testing data has showed the feasibility of the estimate of wheel/ground interactions such as tire friction coefficient. I will further discuss how to use the developed tire model to understand stability and agility of professional racing car driving skills and design human-inspired autonomous aggressive maneuvers for active safety control. |
