Abstract (en)
[origin: WO2007031677A2] The invention concerns a method for diagnosing the condition of at least one tyre of a vehicle wheel connected to the body shell thereof via a suspension, including, for the or each tyre, a step (102) of acquiring the vertical acceleration of the wheel in a reference model of the vehicle. Said method includes a step (108) of filtering the acquired acceleration to eliminate the frequencies thereof lower than a predetermined filtering frequency, a step (110) of determining a vertical excitation applied to the tyre based on the filtered acceleration, and a step (112, 114, 116, 118, 120) of determining the condition of the tyre based on the determined excitation.
