The invention relates to a self-adaptive method for assisting tire inflation, which makes an improvement in the management of tire inflation possible. In the event that the vehicle stops, the central processing unit of a TPMS (Tire Pressure Monitoring System) can go, in a self-adaptive manner, from the receiving configuration of the high-speed "moving" mode to a low-speed "stationary" mode. In parallel, in the event of pressure variation in a tire, the corresponding wheel unit is configured for a transmission in low-speed "stationary" mode. The power Pa received in the central processing unit varies according to a curve (20) that has, in the illustrated example, two low-reception positions (21 and 22). Replacing a high-speed transmission with a low-speed transmission allows for a better signal-to-noise ratio and for increased sensitivity, when receiving about 5 dB, and the risks (21, 22) of interfering with the received power are practically eliminated.
