Foresight Vehicle: Smarter Tires Using Advanced Sensors for Improved Safety

This paper describes work aimed at establishing in-tire sensor system technologies for tire/road contact patch force monitoring. The paper discusses alternative sensor technologies for tire/road contact patch measurement. These technologies include surface acoustic wave (SAW) electroactive materials and magnetoactive soft magnetic materials. The paper also describes the use of finite element based structural analysis techniques to simulate the behavior of the rolling tire at the microscopic level. The finite element simulations are being developed to understand the influence of continuous tire deformation on sensed responses.
