Advances in tire material-structural innovation and information perception technology
As the end-actuator of the ground vehicle drive system,tires play a vital role in many vehicle performances.In recent years,traditional tires have encountered obvious development bottlenecks in multi-parameter information perception,reliability prediction,and environmental adaptability.Tire material optimization,structural innovation,and information perception provide new means to solve the above problems.Innovations in tire materials and structures provide new ideas for solving the inherent problems of tires.Intelligent tire information perception technology enables tires to sense their own status and road information as sensitive components.It is also deeply integrated with technologies such as intelligent driving and vehicle networking.This paper reviews the current status of research on tire material optimization,structural innovation,and information perception technology.Firstly,the breakthroughs made in tire material research under the concept of green tire in recent years in improving rolling resistance,anti-skid performance and wear resistance are reviewed.Secondly,discuss the application and research of pneumatic tires,non-pneumatic tires,and concept tires in structural innovation.Finally,the information perception technology in the development of smart tires is summarized.The integration methods of various sensor systems,sensing element types and data analysis methods are discussed.On this basis,prospects and suggestions are proposed for the needs of autonomous vehicles for tire materials,structures,and intelligence.
