Abstract: A method for detecting a thermal anomaly during running of a tire-wheel assembly (3) of a vehicle (1) equipped with a mounting wheel (5) on which a pneumatic tire is mounted comprises the steps of measuring the internal pressure (P) and temperature (T) of the tire-wheel assembly (3) using a sensor (9) attached to the mounting wheel (5), calculating a monitoring ratio which is a function of the measured pressure and of the measured temperature, repeating the preceding steps and tracking the evolution in the value of the monitoring ratio in order to determine a thermal anomaly.

Abstract: The method for organizing a group of several separate vehicles in a platoon includes an identification step (a) in order to identify the candidate vehicles that are to form the platoonp The method also includes an acquisition step (b) in order to acquire, for each candidate vehicle, at least one parameter associated with a tire of the candidate vehicle, such as the wet grip index of the tire tyre, referred to as the “tire parameter”. Subsequently, based on the tire parameter, a processing step (c) for determining the rank attributed to the particular candidate vehicle in the platoon and/or the inter-vehicle distance which, at a given speed, must separate the candidate vehicle in question from the vehicle immediately in front in the platoon.

Abstract: A method for managing a powertrain (3) of a motor vehicle (1) comprises the following steps: (a) determining a predictive rolling resistance coefficient (Crr) for at least one tyre (10) of the motor vehicle (1); and (b) adapting the operation of the powertrain (3) according to the predictive rolling resistance coefficient (Crr) in order notably to optimize the energy consumption of the motor vehicle (1).

Abstract: Tread (1) for a tire of a heavy-duty vehicle, having a tread surface (10), this tread (1) comprising, near to each of its edges (11), a plurality of open wells (2) on the tread surface when new, these open wells (2) of depth Pmax being arranged circumferentially with a mean distance D between two consecutive open wells; each open well (2) being delimited by two main faces (21, 22) facing one another, this tread being such that each open well (2) is connected to at least one hidden cavity (32) formed within the tread, this hidden cavity (32) opening into a main face (21, 22) of said well.
