<p>Provided in the present invention is a tire pressure sensing system which comprises a tire pressure sensing module formed on a wheel or tire to measure tire pressure and wheel phase angle to select the random location of phase angle, and transmitting data including first wheel phase angle information showing identification code and random location of phase angle, and waiting time information needed to reach a random location of phase angle from a present phase angle location; a wheel rotation sensing module formed on an vehicle body, measures rotation of a wheel to provide second wheel phase angle information; and a control unit receiving data from the tire pressure sensing module, and receiving second wheel phase angle information at standard time of adding waiting time to time of transmitting data to compare the first wheel phase angle information and the second wheel phase angle information to find the location of the wheel in which the tire pressure sensing module is installed, thereby having an effect of simply finding location of the tire pressure sensing module on a direct tire pressure sensing system and simply checking, and reducing battery consumption by reducing power waiting time by directly transmitting data from the wheel rotation sensing module without waiting time.</p> |
