The increasing demand for ground vehicles safety has led to the requirements for effective and accurate vehicle active safety systems, such as Anti-lock Braking System (ABS) and Traction Control System (TCS). As the only link between vehicle and road, the tire is in a very privileged position in a vehicle to acquire vital information which could be used to improve vehicle dynamics control systems. Hence the requirement for an “intelligent tire” that incorporates a system that is able to sense the tire and road conditions, and then interact with the vehicle dynamics control system to optimize the vehicle performance as well as provide warning information to the driver. In this paper, an experimental tire strain-based system is used to establish the proof of concept of an intelligent tire prototype. This experimental system comprises a data acquisition device and three rectangular rosette strain sensors, which can measure the tire surface dynamic strain in real time.
