  • Publication number: 20100217571
    Abstract: A method for estimating the performance, during a braking situation, of a tire to be provided to a vehicle, this method comprising an experimental phase (EXPERIM) including a step (EVAL_MU) of assessing the grip coefficient (?) of the tire on the ground. This assessment step is performed for different values (Vi) of the relative displacement speed of the tire axis with regard to the ground and for different values (gi%) of the tire slip rate on the ground. The experimental phase (EXPERIM) further comprises a modelization step (MODEL) of representing the grip coefficient of this tire, as resulting from the assessment step (EVAL_MU), by a function (MU3D) of the relative displacement speed of the tire axis with regard to the ground and of the slip rate of this tire on the ground.
