abstract

  • Tires are a key sub-system of vehicles that have a big responsibility in comfort, fuel consumption and traffic safety. Nevertheless, current tires are just passive rubber elements which do not contribute actively to improve the driving experience or the vehicle safety. The lack of information that tires provide during driving is the main reason to develop an intelligent tire, which could provide useful information to other systems and become an active safety system. In this paper, an experimental tire strain-based system is used to measure tire tread deformation by means of strain gauges. Tests under different working conditions such as vertical load or slip angle considering a certain camber angle have been carried out using an indoor tire test rig. The results prove that the camber angle has a significant effect on strain signal, so it should be considered for tire working conditions estimation purposes.
