From a traffic safety point-of-view, there is urgent need for intelligent tires as a warning system of road conditions, for optimized braking control on poor road surfaces and as a tire fault detection system. Intelligent tires, equipped with sensors for monitoring applied strain, are effective in improving reliability and control systems, such as anti-lock braking systems (ABSs). The present study introduces the utilization model of strain data for an optimized braking control and road condition warning system. The relationship between strain changes on the inner surface of pneumatic tires, simulating sensor output, and mechanical tire parameters, such as contact patch length, effective radius, and wheel load, is examined. Calculations are carried out using finite element analysis with a simulation of the strain sensor signal when a tire rotates.
