The invention provides a method for improving the stability of a tire pressure monitor, and relates to the field of automobile parts. The situation that the crystal oscillator frequency changes and consequently tire pressure data transmission is not smooth due to the fact that the tire temperature is too high is corrected in time based on the principle that the crystal oscillator frequency can change along with the temperature change and the characteristic that the change curve of the crystal oscillator frequency changes in a similar linear mode. The data transmitting frequency can be adjusted, the power supply energy of the tire pressure sensor is saved, the signal error rate is reduced, the reliability and the stability of the tire pressure sensor are improved and vehicle accidents caused by faults of automobile tires are reduced in combination with actual road conditions.
