Abstract
A system and method for tracking tire positions on a vehicle. Tires are tracked by checking the position of tires synchronized at a predetermined angle when a vehicle speed is equal to or greater than a preset reference speed, on the basis of wheel phase information of a wheel sensor, which is provided at the predetermined angle at every first predetermined time interval through RF communication, and wheel speed information of a wheel speed sensor including tire phase information which is inputted at a second predetermined time interval through a CAN communication line.

13. A tire position tracking system, comprising:
-
a wheel sensor mounted in a specific position on a tire and configured to generate wheel phase information of tires at a predetermined angle every first predetermined time interval; an RF communication unit for transmitting wheel phase information of tires; a wheel speed sensor mounted in a specific position on a tire and generates wheel speed information including tire phase information every second predetermined time interval; and a tire position tracking device configured to determine whether conditions for tracking tire positions are met on a basis of wheel speed information provided by said wheel sensor, and, if the conditions are met, to track tire positions on a basis of the wheel phase information and the tire phase information. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)

21. A method of tracking tire positions with a tire position tracking device, the method which comprises:
-
receiving wheel phase information from a wheel sensor at a predetermined angle every first predetermined time interval; receiving wheel speed information, including tire phase information, from a wheel speed sensor every second predetermined time interval; accumulating a number of times of tire position tracking after the tire position information is synchronized at a predetermined angle based on the tire phase information and wheel phase information; and terminating a tracking of tire positions when the accumulated number of times of tire position tracking reaches the predetermined value after comparison. - View Dependent Claims (22, 23, 24)
