Abstract

A method for matching an emitting valve identifier with that of a wheel in the memory element of an on-board vehicle computer, including steps of specific excitation of the valve and reception of a specific frame sent in response; decoding and analysis of the frame and recognition of the valve identifier; presentation of the identifier to an operator; matching of wheel and valve identifiers and inputting of the identifiers into the memory element. In the method the presentation is performed using a diagnostic tool, the diagnostic tool receiving at least the valve identifier and status data by the on-board receiver.

Claims

1. Method of matching an identifier of an emitting valve of a wheel with an identifier of the wheel registered in a memory of an onboard computer of a motor vehicle, the emitting valve configured to emit, in response to a specific excitation, a specific field of radio signals containing at least one valve identifier and one specific state, an onboard receiver receiving the specific field and transmitting the specific field to the onboard computer, and the onboard computer decoding the specific field, the method comprising:

specific excitation of the emitting valve;

receiving the specific field emitted in response to the specific excitation;

decoding the specific field;

analyzing the at least one valve identifier and one specific state data contained in the specific field and recognizing the identifier of the emitting valve;

presenting to an operator at least the valve identifier data contained in the specific field, and rendering the data distinguishable;

matching the identifier of the wheel with the identifier of the emitting valve by the operator; and

inputting in the memory the identifier of the emitting valve matching the identifier of the wheel;

wherein said presenting is made by a diagnostic tool, the diagnostic tool receiving the at least one valve identifier and one specific state data by the onboard receiver.

2. Method according to claim 1, wherein the at least one valve identifier and one specific state data received by the diagnostic tool are previously decoded by the onboard computer.

3. Method according to claim 1, wherein the specific excitation is produced by an emitting tool.

4. Method according to claim 1, wherein the specific excitation is produced by a deflation of a tire of a wheel bearing the emitting valve.

5. Method according to claim 1, wherein the diagnostic tool carries out analysis of the at least one valve identifier and one specific state data contained in the specific field and recognition of the identifier of the emitting valve.

6. Method according to claim 1, wherein the operator carries out the matching by the diagnostic tool.

7. Method according to claim 1, wherein the inputting in the memory of the valve identifier is matched with the wheel identifier by the diagnostic tool.

8. Method according to claim 7, wherein the diagnostic tool transmits to the onboard computer a valve identifier that it has received from the onboard computer.

9. Method according to claim 1, wherein a set of wheels identifier is entered in the memory matching the wheel identifier and the emitting valve identifier.

10. System of matching an identifier of an emitting valve of a wheel with an identifier of the wheel registered in a memory of an onboard computer of a motor vehicle, the emitting valve configured to emit, in response to a specific excitation, a specific field of radio signals containing at least one valve identifier and one specific state, an onboard receiver receiving the specific field and transmitting the specific field to the onboard computer, and the onboard computer decoding the specific field, the system comprising:

a diagnostic tool configured to receive the at least one valve identifier and the one specific state by the onboard receiver and to present the at least one valve identifier and one specific state to an operator.
