Two-way tire pressure monitoring system and method using ultra high frequencies UHF

摘要

A two-way tire pressure monitoring method using ultra high frequency (UHF) is used for a vehicle controller 100 and one or more tire pressure monitoring module 200. When a tire pressure data signal is transmitted to the vehicle controller 100 by the tire pressure monitoring module 200, the tire pressure data signal is transmitted via first predetermined uhf carrier. When a control signal is transmitted to the tire pressure monitoring module 200 by the vehicle controller 100, the control signal is transmitted via second predetermined uhf. The frequency of the first predetermined UHF carrier and the frequency of the second predetermined UHF carrier are the same or different.
