TIRE AIR PRESSURE TRANSMISSION DEVICE AND TIRE AIR PRESSURE MONITOR SYSTEM |
摘要 |
A tire air pressure transmission device is provided that is configured to set a sampling period or cycle based on a centrifugal acceleration of a wheel in the centrifugal direction, and to detect the value of the gravitational acceleration component of the centrifugal acceleration at each set sampling period. |

1. A tire air pressure transmission device installed on a wheel comprising:
a tire air pressure detection mechanism that detects a tire air pressure of the wheel; an acceleration detection mechanism that detects a centrifugal acceleration while the wheel rotates; a gravitational acceleration component detection mechanism that sets sampling periods based on the centrifugal acceleration and detects a value of a gravitational acceleration component of the centrifugal acceleration at each sampling period, wherein a detected tire air pressure information is transmitted in a wireless signal when the gravitational acceleration component of the centrifugal acceleration has reached a predetermined value.
