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.

    本发明提供一种提高胎压监测器稳定性的方法,涉及汽车配件领域。本发明基于晶振频率会随温度变化而变化的原理,并且其变化曲线呈类线性变化的特征,及时修正由于轮胎温度过高导致晶振频率变化进而造成胎压数据传输不畅的情况。并且结合实际路况,可以调整数据发射频率,节约胎压传感器电源能量,减少信号误码率,提高胎压传感器的可靠性和稳定性,达到减少因汽车轮胎的故障所产生的车辆事故。
