1. A method for identifying a defect in the physical integrity of a tire on a vehicle, comprising steps of:
- measuring a signal that is proportional to the speed of rotation of the tire to be monitored;
calculating harmonic information from said signal;
comparing the calculated harmonic information to a threshold; and
identifying that a defect exists in the physical integrity of the tire when the threshold is exceeded by the calculated harmonic information.

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.

17. A device for monitoring the physical integrity of a tire of a vehicle, comprising:
-
means for measuring a signal that is proportional to a speed of rotation of the tire; means for calculating harmonic information on the speed of the tire based on the measured signal; and means for comparing the harmonic information to a threshold and identifying that a defect in the physical integrity of the tire exists when the threshold is exceeded. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33)
