Method for Monitoring a Tire, Tire Therefore, and Use Thereof
First Claim
1. A process for monitoring a tire (11 to 14) 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 (11 to 14) an electronic chip (21g to 24g) in which is memorised at least an identification code (K11 to K14) which identifies the tire, and providing said chip (21g to 24g) and the central unit (UC) with respectively peripheral (31g to 34g) and central (41 to 44) 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 memorising updated values centralized by the control unit (UC), such values representing at least one evolutive parameter of the use of the tire such as the number of kilometres it has covered (DIST) or its highest running speed (VMAX), wherein the preliminary stage comprises implanting in first and second sidewalls of the tire (11 to 14) respective first and second electronic chips (21g to 24g, 21d to 24d) only one of which (21g, 22d, 23g, 24d) is operational during use, in each of which is memorised the same tire identification code (K11 to K14) and in which are respectively memorised different respective implantation codes (Kg, Kd) of said chips (21g to 24g, 21d to 24d) in the tire, these first and second chips (21g to 24g, 21d to 24d) being respectively provided with first and second peripheral communication circuits (31g to 34g, 31d to 34d) of which only the communication circuit (31g, 32d, 33g, 34d) of the operational chip (21g, 22d, 23g, 24d) can be used during operation to communicate with the central communication circuit (41 to 44), and wherein 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 (21g, 22d, 23g, 24d), active centralized and decentralized historical records (HCA, HDA) simultaneously dedicated to the tire identified by the identification code (K11 to K14) memorised in the operational chip (21g, 22d, 23g, 24d) and to a mounting situation of the tire identified by the implantation code (Kg, Kd, Kg, Kd) memorised in the said operational chip (21g, 22d, 23g, 24d).

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. 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 kilometres (DIST) it has covered or its highest running speed (VMAX).
