PFI-TT: development and integration of tire blowout modeling and control for safe, automated driving

This $550,000 Project Grant awarded by the National Science Foundation (NSF) under the Technology, Innovation, and Partnerships (TIP) program (CFDA 47.084) will fund the development and integration of a tire blowout modeling and control system for advanced driver assistance systems (ADAS).

The key products to be delivered include a high-fidelity, real-time tire blowout prediction model to evaluate the impact on vehicle dynamics and motions. Based on this model, the project will create a shared control system that can mitigate or avoid vehicle accidents and collisions after a tire blowout, without relying on the driver's expertise. The technology will be verified and validated through testing in a full-size vehicle. Kettering University has been awarded a $175,000 sub-grant to support the development and integration of these tire blowout modeling and control capabilities. This award aims to improve vehicle safety and reduce the significant economic costs associated with tire-related crashes.

Abstract

The broader impact of this partnerships for innovation - technology translation (PFI-TT) project addresses safety concerns caused by tire failures. The project may achieve significant economic benefits by reducing financial losses associated with tire blowouts. According to U.S. National transportation safety board (NTSB) and national highway traffic safety administration (nhtsa) reports, each year about 33,000 tire-related passenger vehicle crashes occur, resulting in about 19,000 injuries. In 2020, over 600 fatalities occurred as a result of tire-related passenger vehicle crashes. The national safety council (NSC) estimates the average economic cost per non-fatal disabling injury to be around $98,000, and the average cost per death to be around $1.66 million. Enabled by this technology, a potential 20% tire blowout accident mitigation will save about $600 million in direct cost annually, in addition to saving lives, protecting families, and reducing car insurance costs. This PFI project will create a technology to mitigate or avoid vehicle accidents and collisions after a tire blowout. A high-fidelity and real-time implementable tire blowout model will be developed to predict vehicle dynamics and motions after tire blowout. Based on the developed model, the characteristics of tire blowout and the impacts on vehicle motions will be evaluated online and utilized in shared control design. The design will be commercialized as a new advanced driver assistance systems (adas) function that does not rely on drivers? Experience or expertise to handle tire blowout accidents. The developed model and control algorithms will be verified and validated in a full-size vehicle under various operation conditions. This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the foundation's intellectual merit and broader impacts review criteria.- subawards are planned for this award.
