Abstract
A self-adaptive method for assisting tire inflation enables control of tire inflation. If the vehicle stops, the central unit of a TPMS (Tire Pressure Monitoring System) can change in a self-adaptive manner from the reception configuration of the “moving” mode at a high bit rate to a “stationary” mode at a low bit rate. At the same time, if there is a variation in the pressure of a tire, the corresponding wheel unit is set for transmission in “stationary” mode at a low bit rate. The power Pa received at the central unit varies according to a curve (20) which shows, in the illustrated example, two positions of poor reception. By replacing high bit rate transmission with low bit rate transmission, the signal/noise ratio is improved and there is a gain in reception sensitivity of about 5 dB, and the risks of disturbance of the received power are virtually eliminated.
