Title:
TIRE AIR PRESSURE MONITORING SYSTEM, DETECTION DEVICE, AND MONITORING DEVICE
Document Type and Number:
WIPO Patent Application WO/2017/068987
Kind Code:
A1
Abstract:
An air pressure monitoring system for tires (3) is provided with: a plurality of detection devices (2) that are provided individually to a plurality of tires (3) in a vehicle and that wirelessly transmit an air pressure signal including air pressure information for the tires (3) in response to a request signal; and a monitoring device (1) that transmits the request signal to the detection devices (2), receives the air pressure signals transmitted from the detection devices (2) in response to the request signal, and monitors the air pressure of each of the tires (3). When the detection devices (2) receive the request signal, said detection devices (2) measure the received signal strength of the received request signal and transmit the air pressure signal to the monitoring device (1) at a timing that differs in accordance with the measured received signal strength. The monitoring device (1) receives air pressure signals transmitted at different timings from the plurality of detection devices (2).
