Patent number: 11912074Abstract: A method for processing inflation defects of a tyre of a vehicle is disclosed, the tyre being equipped with sensors for measuring the pressure and the temperature of the internal cavity of said tyre. The pressure and the temperature of the internal cavity of the tyre are measured periodically and, as soon as an inflation defect of a tyre is detected, an alert is signalled to the driver of the vehicle, in which there is also transmitted to the driver of the vehicle a maximum speed setpoint: which, when the measured inflation pressure of the tyre is greater than or equal to a first inflation pressure threshold value p1, is a first maximum speed setpoint value V1; and which, when the measured inflation pressure of the tyre is less than said first pressure threshold value p1 and greater than or equal to a second pressure threshold value p2, decreases as a function of said measured inflation pressure of the tyre.Type: GrantFiled: May 7, 2018Date of Patent: February 27, 2024Assignee: COMPAGNIE GENERALE DES ETABLISSEMENTS MICHELINInventors: Olivier Muhlhoff, Arnaud Delbast, Aurelien Fabre
