Patent ID: 7652561

Claim:
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 tire wherein 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, 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, 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.
