Abstract:
A method for detecting vibrations generated by the running of a tire on a safety insert, wherein a vibration signal is measured within a given frequency band and the measurement thus made is processed to detect a mode of resonance generated by this running. The energy of the signal measured by a sensor in two frequency bands, one being narrow and the other being wide, which are centered on the same line of the mode of resonance, is determined. The ratio of these two energies is compared with a given warning threshold.
