Method for detecting a tyre blowout risk

A computer configured to detect a risk of blowout of a tire fitted to a vehicle, comprising a plurality of tires, said tire comprising a sensor capable of periodically measuring a value of the temperature of the gases present inside said tire and of sending said measured temperature values to said computer of the vehicle, said tire being characterized by an internal temperature and a “standard” range representative of the internal temperatures of the tire in the absence of risk of blowout, said standard range comprising an upper limit, the computer being configured to implement a method comprising:

• periodically measuring, by said sensor, the temperature of the gases present inside the tire,
• sending each measured temperature value to said computer,
• receiving, by the computer, each measured temperature value sent by the sensor,
• when the measured temperature value is higher than or equal to a first threshold, higher than the upper limit of the standard range, determining, over a first predetermined time period, the change in the measured temperature and comparing the measured temperature value with a second threshold, higher than the first threshold,
• when the measured temperature has increased by a value higher than or equal to a threshold difference over the first predetermined time period, detecting, by the computer, a risk of blowout of the tire,
• when the measured temperature value is higher than or equal to the second threshold, comparing the measured temperature value with a third threshold, higher than the second threshold,
• when the measured temperature value is higher than or equal to the third threshold or when the measured temperature value is higher than or equal to the second threshold over a second predetermined time period, detecting, by the computer, a risk of blowout of the tire.
