Abstract
A method for estimating the severity of conditions of use of a tire installed on a vehicle comprises the following steps: a step of measuring the speed of the vehicle and the load of the vehicle, a step of evaluating, as a function of the measurements performed, the power of the internal heat dissipations of the tyres, and a step of determining, as a function of this power, the internal temperature of the tyre, a step of recording the number of wheel revolutions performed and/or the time spent in conditions of use corresponding to a given temperature interval. There is also a system that makes it possible to implement said method.

A method for estimating the severity of conditions of use of a tire installed on a vehicle, the method comprising the following steps:
- measuring a speed of the vehicle and a load of the vehicle;
- evaluating, as a function of the measurements performed, a power of internal heat dissipations of the tire;
- determining, as a function of the power, an internal temperature of the tire;
- and
- recording at least one of a number of wheel revolutions performed and a time spent in conditions of use corresponding to a given temperature interval.
A system for estimating the severity of conditions of use of a tire installed on a road vehicle, the system comprising a braking computer comprising:
- means for measuring a speed of the vehicle and a load of the vehicle;
- means for evaluating, as a function of the measurements performed, a power of the internal heat dissipations of the tire;
- means for determining, as a function of the power, an internal temperature of the tire;
- and
- means for recording at least one of a number of wheel revolutions performed and a time spent in conditions of use corresponding to a given temperature interval.
