Abstract
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. Indoor tire rolling tests including steady state straight line and cornering are used to demonstrate the feasibility of the
measuring tire strain history with a view to determining tire dynamic strain characteristics. Tire dynamic strain
characteristics are extracted and analyzed with respect to the variation of tire operational conditions, such as inflation
pressure, rolling speed and pre-loading. These relationships between dynamic strain characteristics and tire operational
conditions indicate potential application of tire strain measurement in estimating tire behavior.
