CROSS-REFERENCE TO RELATED PATENT APPLICATION

This application claims the benefit of priority to Taiwan Patent Application No. 110128009 filed on 30 Jul. 2021. The entire content of the above identified application is incorporated herein by reference.

FIELD OF THE DISCLOSURE

The present disclosure relates to a tire pressure detecting system for vehicles, and more particularly to a duplex communication between a Bluetooth tire pressure detector and a transceiver host to complete positioning and tire condition detection.

BACKGROUND OF THE DISCLOSURE

The automatic positioning technology of the tire pressure detector means that the transceiver host in the car can receive the signal and automatically determine the position of the tire pressure detector through the tire speed, rotation phase angle, or signal strength. Some tire pressure detectors configured by car manufacturers can automatically locate each time the vehicle is stopped. However, some tire pressure detectors must be removed from the tire and replaced with a new product or be calibrated when the tire pressure detector is out of action due to insufficient power, or during routine maintenance, such as tire rotation for average wear, or tire replacement. Once the locating between the tire pressure detector and the transceiver host is completed, the tire pressure detector simplex transmits the temperature and pressure to the transceiver host, so that the transceiver host can obtain the tire condition.

The conventional automatic locating technology of the tire pressure detector is one-way data transmission from the tire pressure detector (as shown inFIG.6). Generally, the tire pressure detector transmits the locating data would cost about 10 minutes. The positioning calculation of the tire pressure detector is very power-consuming, and has the following effects:

1. Even if the transceiver host has complete locating with the tire pressure detector, the tire pressure detector will continue to transmit the locating data to the transceiver host.

2. After the tire pressure detector and the transceiver host complete the locating, every time the vehicle stops temporarily for more than 10 minutes and restarts, the tire pressure detector will transmit the locating data again, thus wasting time transmitting the locating data.

3. Due to the general tire pressure detector transmitting the locating data for 10 minutes at a fixed time, the transceiver host cannot receive continuous valid data when there is an error or interruption in the locating data received by the transceiver host. As a result, the tire pressure detector can re-transmit the locating data again only when the vehicle is stopped and turned off for restart.
