Abstract

A method for synchronizing the measurements obtained, over a given period, from a number of measurement acquisition means for acquiring measurements of characteristics associated with the stresses withstood by a tire fitted on a running vehicle. The measurement acquisition means are brought into operation independently of one another and at least one indexing at a given instant of the measurements from each of said means is created relative to a time-measuring reference means.

Claims

1. A method for synchronizing the measurements obtained, over a given period, from a number of measurement acquisition means for acquiring measurements of characteristics associated with the stresses withstood by a tire fitted on a running vehicle, wherein the measurement acquisition means are brought into operation independently of one another and wherein at least one indexing at a given instant of the measurements from each of said means is created relative to a time-measuring reference means.

2. The method according to claim 1, wherein, outside of said at least one indexing at a given instant, the measurement acquisition means are continually independent of one another and said means acquire measurements autonomously.

3. The method according to claim 1, wherein the reference means is one of the measurement means.

4. The method according to claim 1, wherein the reference means is an independent additional means.

5. The method according to claim 1, wherein the indexing at a given instant of the measurements from each of said means is done with a time offset relative to the other means.

6. The method according to claim 1, wherein each of the measurements is corrected by taking into account the temporal drift of the acquisition means concerned.

7. The method according to claim 1, wherein an indexing at a given instant at the start of the measurements of each of said means is created relative to the time-measuring reference means and an indexing at a given instant at the end of the measurements of each of said means is created relative to the time-measuring reference means.

8. The method according to claim 1, wherein an indexing at a given instant at regular intervals, during the given period, of the measurements of each of said means is created relative to the time-measuring reference means.

9. The method according to claim 1, wherein each measurement acquisition means is associated with a clock, with memory elements and with an energy source.
