1. A TPMS auto localization system for on-demand tire parameter acquisition, comprising:
- a central unit configured to receive and transmit a radio-frequency (RF) signal;
a tire module associated with a tire, and configured to measure one or more tire parameters based on a received low frequency (LF) command and transmit the one or more tire parameters to the central unit; and
a repeater module associated with the tire module, and configured to receive the RF signal from the central unit and translate the RF signal into a LF command to be transmitted to the tire module.

Abstract
A TPMS auto localization system for on-demand tire parameter acquisition and an associated method includes a central unit configured to receive and transmit radio-frequency (RF) signals, and a tire module associated with a tire. The tire module is configured to measure one or more tire parameters based on a received low frequency (LF) command and transmit the one or more tire parameters to the central unit. A repeater module is associated with the tire module, and is configured to receive the RF signal from the central unit and translate the RF signal into a LF command to be transmitted to the tire module.

11. A repeater module in a TPMS auto localization system, comprising:
-
a RF receiver configured to receive a radio-frequency (RF) signal from a central unit; a translation circuit and/or associated software configured to selectively translate the RF signal to a LF command based on a condition; and a LF transmitter configured to receive the LF command from the translation circuit and/or associated software and transmit the low frequency (LF) command to a tire module. - View Dependent Claims (12, 13, 14, 15)

16. A method for on-demand tire parameter acquisition comprising:
providing a TPMS auto localization system within the vehicle, the TPMS auto localization system comprising, a central unit configured to receive and transmit radio frequency (RF) signals; a tire module associated with a tire configured to measure one or more tire parameters based on a received low frequency (LF) command and transmit the tire parameter to the central unit; and a repeater module associated with the tire module configured receive the RF signal from the central unit and translate the RF signal into the LF command to be transmitted to the tire module; generating a RF signal containing a module ID and an instruction to address the tire module within the central unit; transmitting the RF signal from the central unit to the repeater module; selectively translating the RF signal into the LF command within the repeater module, based on a condition; transmitting the LF command from the repeater module to the tire module; determining the tire parameters based on the LF command; and transmitting the measured tire parameters from the tire module to the central unit. - View Dependent Claims (17, 18, 19, 20)
