PROBLEM TO BE SOLVED: To exactly evaluate a low expansion state in a range of speed and load or cavity pressure for alarming an excessive temperature and a temperature measurement value. SOLUTION: This information processing method in a tire pressure monitoring system includes a step for setting a reference temperature, a step for determining a pressure alarm threshold value at the reference temperature, a step for measuring gauge pressure and gauge temperature within a tire cavity, a step for correcting the gauge pressure to a pressure value filtered at the reference temperature by using an ideal gas law, and a step for comparing the filtered pressure value with the pressure alarm threshold value to decide the necessity of an alarm signal.
