TIRE AIR PRESSURE DETECTING DEVICE AND DETECTED DATA TRANSMITTING METHOD OF TIRE AIR PRESSURE DETECTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a tire air pressure detecting device capable of reducing the probability of the detected data not being received by a monitor device, and providing high reliability on receiving the detected data.;SOLUTION: A centrifugal sensor 23 is mounted on sensor devices 14a-14d, and a CPU 25 calculates a rotating period of a tire on the basis of the centrifugal force detected by the centrifugal force sensor 23. The CPU 25 determines a transmission interval of the detected data which is not integral multiple of the rotating period, on the basis of the rotating period, and transmits the detected data of the same contents to the monitor device through a transmitting circuit 19 in accordance with the determined transmission interval.;COPYRIGHT: (C)2004,JPO
