Abstract:
A system and method are provided for monitoring the physical integrity of a tire. The system and method include measuring a signal proportional to the speed of rotation of the wheel and calculating a harmonic signal of the round of wheel (e.g., equal to the energies of the harmonics of this signal), then comparing the result with a threshold and activating an alarm when over-passing this threshold.
