Abstract

Provided are a tire pressure monitoring device, an information transmitting method thereof, and an integrated receiver system. A tire pressure monitoring device according to an aspect of the present invention includes a first sensing unit sensing a pressure of a tire, a second sensing unit detecting whether a vehicle is driving by sensing at least one of acceleration, motion, and shock, and a calculation unit transmitting, to an integrated system of the vehicle, pressure information of the tire at a first data transfer rate corresponding to a data transfer rate of a body control module or a smart key system when the second sensing unit detects that the vehicle is not driving.

Claims

1. A tire pressure monitoring device comprising:

a first sensing unit sensing a pressure of a tire;

a second sensing unit detecting whether a vehicle is driving by sensing at least one of acceleration, motion, and shock; and

a calculation unit transmitting, to an integrated system of the vehicle, pressure information of the tire at a first data transfer rate corresponding to a data transfer rate of one or more controllers transmitting signaling of at least a pair of tire pressure monitoring, motion control, safety status and access of the vehicle when the second sensing unit detects that the vehicle is not driving.

2. The tire pressure monitoring device of claim 1, wherein the calculation unit transmits the pressure information of the tire at a second data transfer rate that is faster than the first data transfer rate when the second sensing unit detects that the vehicle is driving.

3. The tire pressure monitoring device of claim 1, wherein the calculation unit transmits the pressure information of the tire at the first data transfer rate if the pressure of the tire is changed to be equal to or greater than a predetermined critical value when the vehicle is not driving.

4. The tire pressure monitoring device of claim 1, wherein the calculation unit transmits the pressure information of the tire at the first data transfer rate at a predetermined transmission cycle and then is switched to a sleep state.

5. An integrated receiver system comprising:

a receiving unit receiving a signal of a transmission frequency;

a converting unit converting the received signal to information data according to a first data transfer rate when a vehicle is not driving and converting the received signal to the information data according to a second data transfer rate that is faster than the first data transfer rate when the vehicle is driving, the first data transfer rate being associated with one or more controller transmitting signaling of at least a pair of tire pressure monitoring, motion control, safety status and access of the vehicle; and

a processing unit performing an operation corresponding to the information data.

6. The integrated receiver system of claim 5, wherein, when the vehicle is not driving, the received signal is a signal from a tire pressure monitoring system (TPMS), or a remote controller of the vehicle.

7. The integrated receiver system of claim 5, wherein, when the vehicle is driving, the received signal is a signal from a tire pressure monitoring system (TPMS).

8. The integrated receiver system of claim 6, wherein, when the received signal is the signal from the tire pressure monitoring system, the information data is tire pressure information, and the processing unit checks whether the tire is abnormal on the basis of the tire pressure information to give a warning when the tire is abnormal.

9. The integrated receiver system of claim 7, wherein, when the received signal is the signal from the tire pressure monitoring system, the information data is tire pressure information, and the processing unit checks whether a tire is abnormal on the basis of the tire pressure information to give a warning when the tire is abnormal.

10. The integrated receiver system of claim 5, wherein the receiving unit and the converting unit wake up at a predetermined cycle respectively to receive the signal of the transmission frequency and convert the received data to the information data and then are switched to a sleep state.
