METHOD AND SYSTEM FOR DIAGNOSING THE CONDITION OF A MOTOR VEHICLE TYRES
First Claim
1. Method of diagnosing the state of tires of a front wheel and of a rear wheel of a motor vehicle arranged on a same side of the vehicle and connected to the body thereof by means of suspensions, the method including a step of acquiring the vertical accelerations of said wheels in a referential of the vehicle, wherein said method comprises:
- a step of temporally resetting one of the acquired accelerations on the other of the acquired accelerations;
a step of estimating coefficients of stiffness of the tires as a function of the thus temporally reset accelerations; and
a step of determining the state of the tires as a function of the estimated coefficients of stiffness.

Abstract
The invention concerns a method for diagnosing the condition of tires of a front wheel and of a rear wheel of a motor vehicle arranged on the same side of the vehicle and connected to the body shell thereof via suspension means. Said method includes a step (102) of acquiring the vertical acceleration of said wheels in a reference model of the vehicle, a step (104) of time-based resetting of one of the acquired accelerations on the other of the acquired accelerations, a step (112) of estimating the coefficients of stiffness of the tires based on the thus temporally reset accelerations, and a step (120) of determining the condition of the tires based on the estimated coefficients of stiffness.
