<p>Provided in the present invention is a tire pressure monitoring system which comprises a tire pressure sensing module measuring tire pressure and wheel phase angle by being formed on a wheel or a tire, and transmitting data including identification code and first wheel phase angle information on a random location of phase angle; a wheel rotation sensing module formed on a vehicle body, and measuring rotation of the wheel to providing second wheel phase angle information; and a control unit receiving data from the tire pressure sensing module, receiving second wheel phase angle information of the time when data is transmitted, and compares the first wheel phase angle information and the second wheel phase angle information to find location of the wheel in which the tire pressure sensing module is installed, thereby having an effect of automatically assigning location of the tire pressure sensing module by simply finding on a direct tire pressure sensing system.</p> |
