Claim:
1. An assistance method for adjusting the pressure of a tire mounted on a wheel of a motor vehicle equipped with an electronic module adapted to transmit, to an on-board central unit in said vehicle, signals comprising data enabling the pressure of the associated tire to be determined, said assistance method comprising the following procedures, during an action of adjusting the pressure of the tire of a wheel: transmitting, by the electronic module fitted to this wheel, of a sequence of signals, called measurement signals, each comprising data for determining a measured value Pm(t) of the tire pressure, if the measured value Pm(t) of the pressure corresponds to a predetermined value of setpoint pressure Pc, a procedure of managing the cessation of the pressure adjustment action, comprising a final step of signaling the end of said adjustment action, initially, after the reception of a number n of initial measurement signals, where n≧2, the gradient or slope Cd of the straight line representing the variation of the measured value Pm(t) of the pressure as a function of time is determined, and then, on reception of each subsequent measurement signal, the remaining time required to reach the setpoint pressure Pc is deduced from the ratio |Pc-Pm(t)|/Cd, and, if this remaining time expires before the reception, or simultaneously with the reception, of a new measurement signal, the procedure for managing the cessation of the pressure adjustment action is initiated.
