Abstract

The method is for transmitting data identifying a valve of a wheel to a receiver on board a vehicle. The method includes, excitation of the valve, transmission by the valve of a frame including at least a code identifying the valve, and reception of the frame by the on-board receiver. The reception includes a refreshing of a memory range contained in the receiver by the data from the frame received. The method the includes a reading operation, by a diagnostic instrument, of the most recent data contained in the memory range, and an operation of writing to an area of memory dedicated to storing identifier codes, by a diagnostic instrument, of at least part of the data read including an identifier code. The writing operation is carried out after validation by an operator.

Claims

1. A method for transmitting data identifying a valve of a wheel to a receiver on board a vehicle, the receiver including a buffer and an identifier code memory, the method comprising:

exciting the valve during valve excitation events;

transmitting, by the valve, of a data frame comprising data including at least a valve identifier code and event data indicating a type of valve excitation event that caused excitation of the valve;

receiving of the data frame by the receiver including a refreshing of the buffer in the receiver by replacing data stored in the buffer with the data from the data frame received;

reading and processing, by a diagnostic instrument, of a most recent data stored in the buffer including verification of the data based upon a predefined format;

validating the most recent data read from the buffer by the diagnostic instrument; and

writing to the identifier code memory without matching of the valve identifier code from the most recent data read and validated.

2. The method as claimed in claim 1, wherein the buffer has a local identifier associated therewith to allow access to the content of the buffer by the operator during a data reading operation.

3. The method as claimed in claim 1, wherein the data frame transmitted by the valve comprises a radio frequency (RF) data frame.

4. A method of communicating data from a valve of a wheel to a receiver on board a vehicle, the receiver including a buffer and an identifier code memory, the method comprising:

transmitting a data frame comprising data including at least a valve identifier code from the valve and event data excitation of the valve;

replacing data stored in the buffer of the receiver with the data of the data frame;

reading and processing the data stored in the buffer with the diagnostic instrument including verification of the data based upon a predefined format;

validating the data read from the buffer; and

writing the valve identifier code from the data validated to the identifier code memory without matching the valve identifier code to a wheel identifier code.

5. The method as claimed in claim 4, wherein the buffer has a local identifier associated therewith to allow access to the content of the buffer during a data reading operation.

6. The method as claimed in claim 4, wherein the data frame transmitted by the valve comprises a radio frequency (RF) data frame.

7. A system for transmitting data identifying a valve of a wheel to a receiver on board a vehicle, the system comprising:

a transmitter instrument to perform a valve excitation event;

a valve transmitter associated with the valve, to transmit a data frame from the valve to the receiver in response to a valve excitation event, the data frame comprising data including at least a valve identifier code and event data indicating a type of valve excitation event that caused excitation of the valve;

a buffer in the receiver to replace data stored therein with the data contained in the data frame received;

a identifier code memory in the receiver; and

a diagnostic instrument to read the data stored in the buffer including verification of the data based upon a predefined format, and write the valve identifier code without matching of the valve identifier code to a wheel identifier code, to the identifier code memory in the receiver based upon validation of the data read from the buffer.

8. The system as claimed in claim 7, wherein the buffer has a local identifier associated therewith to allow access to the content of the buffer during a data reading operation.
