Title:
TIRE-PRESSURE MONITORING SYSTEM AND MONITORING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/188027
Kind Code:
A1
Abstract:
This tire-pressure monitoring system comprises a plurality of detection devices that detect the air pressure in the tires of a vehicle, and a monitoring device that wirelessly communicates with the detection devices and monitors the air pressure of the tires. The monitoring device stores a plurality of tire positions in association with detection device sensor identifiers related to the tire positions. The monitoring device transmits, to each tire position, a first request signal including a corresponding sensor identifier, and a second request signal not including the sensor identifier. When a detection device receives a first request signal including the sensor identifier of the detection device, the detection device transmits a response signal. When a detection device receives a second request signal, the detection device unconditionally transmits a response signal. The monitoring device detects the presence of a tire rotation by determining whether a single response signal corresponding to each request was respectively received.
