TIRE-VALVE ID REGISTRATION SYSTEM

Title:

TIRE-VALVE ID REGISTRATION SYSTEM

Document Type and Number:

WIPO Patent Application WO/2015/111573

Kind Code:

A1

Abstract:

This tire-valve ID registration system is equipped with a plurality of tire valves (4) and a receiver (12). Each of the tire valves transmits a radio wave (Sva) including a unique valve ID and tire-air-pressure data. The receiver monitors the air pressure of each tire by registering the valve ID upon receiving the radio wave transmitted by each of the tire valves. Each of the tire valves selectively executes one of a plurality of radio-wave transmission modes according to whether the vehicle is moving or stopped. The receiver includes a mode-prediction unit (19) for monitoring whether the vehicle is moving or stopped, and predicting the current radio-wave transmission mode of the tire valves; and an ID registration unit (20) for handling a valve ID transmitted from a tire valve in a radio-wave transmission mode that matches the radio-wave transmission mode predicted by the mode prediction unit as the valve ID of the vehicle, and registering the same in the receiver.
