Abstract

A TPMS (tire pressure monitoring system) sensor setting method is disclosed and performed by: using a setting tool to input a location code into the TPMS sensor to be set so that the TPMS sensor can feed the location code and its ID to the on-vehicle main unit for enabling the on-vehicle main unit to establish the relationship between the ID of the TPMS sensor and its location.

Claims

1. A TPMS (tire pressure monitoring system) sensor position setting method, comprising the steps of:

A. providing a setting tool;

B. operating said setting tool to select the position of the TPMS sensor to be set and to select desired physical warning threshold values;

C. enabling said setting tool to transmit a triggering data to trigger said TPMS sensor, said triggering data comprising a trigger signal and a location code, wherein said triggering data further comprises said physical warning threshold values, and said triggering data is only transmitted to trigger said TPMS sensor when said triggering data comprises said physical warning threshold values;

D. said TPMS sensor feeding back to said on-vehicle main unit a response signal containing said location code and an ID of said TPMS sensor after received said trigger signal, wherein said TPMS sensor stores said location code and said physical warning threshold values after received said triggering data; and

E. said on-vehicle main unit linking said location code and said ID and storing them in a memory therein after received said response signal from said TPMS sensor.

2. The TPMS (tire pressure monitoring system) sensor position setting method as claimed in claim 1, said on-vehicle main unit is switched into a learning mode before the user starts the TPMS (tire pressure monitoring system) sensor position setting method.

3. The TPMS (tire pressure monitoring system) sensor position setting method as claimed in claim 1, wherein said response signal further comprises physical information measured by said TPMS sensor.

4. The TPMS (tire pressure monitoring system) sensor position setting method as claimed in claim 1, wherein said setting tool provides said triggering data at a low frequency.

5. The TPMS (tire pressure monitoring system) sensor position setting method as claimed in claim 1, wherein said TPMS sensor provides said response signal to said on-vehicle main unit in a wireless manner.

6. The TPMS (tire pressure monitoring system) sensor position setting method as claimed in claim 1, wherein said on-vehicle main unit is switched into a learning mode before the user starts the TPMS (tire pressure monitoring system) sensor position setting method.
