Method for assisting with inflating the tires of a vehicle

A self-adaptive method for assisting in the inflation of tires of a vehicle, the vehicle being stationary in an immobilization mode, the method comprising:

• continuously measuring at least a pressure of each tire by way of a wheel unit associated with each tire,
• transmitting signals on a state of the tires via a wireless link between each wheel unit and a central unit, the central unit continuously analyzing these signals and then transmitting information in relation to the state of the tires to an information module, a pressure variation above a predetermined threshold of a tire associated with each wheel unit and detected by the wheel unit giving rise to transmission of a signal to the central unit, these signals being transmitted by each wheel unit through frequency-shift keying between two first predetermined frequencies defining, between them, a first frequency band, wherein, when the vehicle is stationary in an immobilization mode, each wheel unit is reprogrammed such that each wheel unit transmits, to the central unit, a first frequency-shift keyed signal with the first frequency band and a second frequency-shift keyed signal with a second frequency band wider than the first band.
