Abstract
Disclosed is a tire pressure monitoring system and a method for performing auto-location thereof that simply identifies the position of a tire pressure monitoring module in a direct scheme tire pressure monitoring system to perform auto-location.
Claims14
A tire pressure monitoring system comprising:
- a tire pressure monitoring module provided in a wheel or a tire and measuring pressure of the tire and a wheel phase angle of the wheel, transmitting a burst signal comprises plurality of consecutive data frames including a tire pressure information and an identification code at a predetermined position of phase angle, and setting a delay time between the consecutive data frames of the burst signal based on the predetermined position of phase angle;
- a wheel monitoring module provided in a vehicle body and measuring rotation of the wheel to provide a phase angle information of the wheel;
- and
- a control unit receiving the burst signal from the tire pressure monitoring module, receiving the phase angle information of the wheel at the time of transmitting the burst signal from the wheel monitoring module, calculating the predetermined position of phase angle from the delay time, comparing the calculated predetermined position of phase angle and the phase angle information of the wheel with each other to identify the position of the wheel on which the tire pressure monitoring module is mounted.

A method for performing auto-location of a tire, the method comprising:
- measuring, by a tire pressure monitoring module provided in a wheel or the tire, pressure of the tire and a wheel phase angle of the wheel;
- transmitting, by a tire pressure monitoring module, a burst signal comprises plurality of consecutive data frames including a tire pressure information and an identification code at a predetermined position of phase angle, wherein a delay time between the consecutive data frames of the burst signal is set based on the predetermined position of phase angle;
- receiving phase angle information at the time of transmitting the burst signal from a wheel monitoring module provided in a vehicle body and measuring rotation of the wheel;
- and
- calculating the predetermined position of phase angle from the delay time and comparing the calculated predetermined position of phase angle with the phase angle information to identify the position of the wheel on which the tire pressure monitoring module is mounted.
