1. A method for processing inflation defects of a tire of a vehicle, the tire being equipped with sensors for measuring a pressure and a temperature of an internal cavity of the tire, the method comprising the steps of:
periodically measuring the pressure and temperature of the internal cavity of the tire;
detecting an inflation defect of the tire, the inflation defect being indictive of a leak;
signaling, as soon as the inflation defect of the tire is detected, an alert to a driver of the vehicle; and
transmitting a maximum speed setpoint to the driver,
wherein the maximum speed setpoint, when the measured inflation pressure of the tire is greater than or equal to a first pressure threshold value p1, is a first maximum speed setpoint value V1, and
wherein the maximum speed setpoint, when the measured inflation pressure of the tire is less than the first pressure threshold value p1 and greater than or equal to a second pressure threshold value p2, is a function of the measured inflation pressure of the tire where the maximum speed setpoint decreases with decreasing inflation pressure, the maximum speed setpoint transmitted decreasing progressively between the first maximum speed setpoint value V1 and a second maximum speed setpoint value V2 as a curvilinear function of the measured inflation pressure of the tire.
