Method for monitoring a tire, tire therefore, and use thereof
First Claim
1. A process for monitoring a tire fitted on a land vehicle (VH) provided with a central control unit (UC), comprising:
- a preliminary stage that comprises implanting in a sidewall of the tire an electronic chip in which is memorized at least an identification code which identifies the tire, and providing said chip and the central unit (UC) with respectively peripheral and central communication circuits connected to one another via a data transmission path involving no physical contact; and
a functional stage comprising a monitoring operation that includes compiling and updating a historic record of the use of the tire by memorizing updated values centralized by the control unit (UC), such values representing at least one evolutive parameter of the use of the tirewherein the preliminary stage comprises implanting in first and second sidewalls of the tire respective first and second electronic chips only one of which is operational during use, in each of which is memorized the same tire identification code and in which are respectively memorized different respective implantation codes of said chips in the tire, these first and second chips being respectively provided with first and second peripheral communication circuits of which only the communication circuit of the operational chip can be used during operation to communicate with the central communication circuit, andwherein the functional stage comprises centralized and decentralized monitoring operations (MAJOURC, MAJOURD) that include, respectively, compiling and/or updating, in the central unit (UC) and in the operational chip, active centralized and decentralized historical records (HCA, HDA) simultaneously dedicated to the tire identified by the identification code memorized in the operational chip and to a mounting situation of the tire identified by the implantation code memorized in the said operational chip.

Abstract
A process for monitoring a tire (11 to 14) mounted on a land vehicle (VH), the process being implemented by means of a central control unit (UC) and an electronic chip (21g to 24g) implanted in a sidewall of the tire. A tire is provided with two chips (21g to 24g, 21d to 24d) implanted in its respective sidewalls, but only one of them is operational during use depending on the mounting direction of the tire. The chips of the same tire contain a given tire identification code (K11 to K14) and specific respective codes (Kg, Kd) that indicate their implantation in the tire. The process is implemented by compiling and/or updating, both in the central unit (UC) and in the operational chip (21g, 22d, 23g, 24d), historical records of the use of the tire by memorising updated values of evolutive parameters of the use of the tire, such as the number of kilometers (DIST) it has covered or its highest running speed (VMAX).
