METHOD AND SYSTEM FOR DIAGNOSING THE CONDITION OF A MOTOR VEHICLE TYRES

摘要

The invention concerns a method for diagnosing the condition of tyres 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 accelerations 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 tyres based on the thus temporally reset accelerations, and a step (120) of determining the condition of the tyres based on the estimated coefficients of stiffness.
