A method for transmitting n identification signals (P-P) formulated according to n different protocols, using an electronic casing () provided on a wheel () of a vehicle, as part of an angular correlation locating procedure. An electronic casing () is used, which is programmed to carry out, per wheel turn, x transmissions commanded for x angular positions offset from each other by predetermined angular values and, during each sending operation, a fixed angular position of the electronic casing () is determined, to which position is assigned the reference angular position function for determining the x transmission angular positions of the electronic casing, and a burst of n identification signals sent consecutively for transmission successive angular positions of the electronic casing () is transmitted, each of the signals being formulated according to one of the n protocols and including data for identifying the electronic casing and the transmission angular position thereof.

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 &#x201c;stationary&#x201d; mode at a low bit rate. The power Pa received at the central unit varies according to a curve () 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.

A low-frequency emission electronic unit (') includes two low-frequency antennas (B, B). The second antenna (B) is passive and resonant, oriented along the main axis (Y) of the first low-frequency antenna (B) and is adapted to generate two low-frequency fields (D, D&#x2032;) at right angles to the field (D) emitted by the first antenna (B). The low-frequency emission electronic unit (&#x2032;) makes it possible to reduce the zones of rupture of reception of the low-frequency signals by the wheel unit () situated in proximity in which the low-frequency signals emitted by the low-frequency emission electronic unit are not received by the closest wheel unit (). A low-frequency signal transmission method alternating the emissions of waves by the two antennas (B, B) is also described.
