ABSTRACT:
A method of detecting a rapid leak of gas contained in an automobile tire based on periodic measurements of a pressure Pa and a temperature Ta of the gas. The method includes determining a reference pressure Pcref, calculating an alarm threshold pressure Sref from the reference pressure Pcref, calculating a temperature-compensated pressure Pc at each measurement acquisition period, and comparing the compensated pressure Pc with the alarm threshold pressure Sref, wherein the leak is detected if the compensated pressure Pc is less than the alarm threshold pressure Sref.
