Patent ID: 7987705

Claim:
A method for estimating, during a braking situation, the performance of a tire to be provided to a vehicle, the method comprising: an experimental phase including: a step of assessing the grip coefficient of the tire on the ground, performed for different values of the relative displacement speed of the tire axis with regard to the ground and for different values of the tire slip rate on the ground, and a modelization step of representing the grip coefficient of said tire, as resulting from the assessment step, by a function of the relative displacement speed of axis of said tire with regard to the ground and of the slip rate of said tire on the ground; and a predictive phase including an operation of determining an overall indicator of the tire performance, which comprises integrating, against the relative displacement instantaneous speed of axis of the tire and of the ground, and against the slip rate of said tire on the ground, the function representative of the tire grip coefficient, over a domain of instantaneous speeds and slip rates corresponding to a real or simulated braking sequence.
