Abstract: A system is provided for assessing a condition of a tire. The system includes first and second individual modules, a data transmission gateway, and a collaboration device. The first and second individual modules are for assessing the condition of the tire. Each of the first and second individual modules includes a housing, which is structured to be placed on a ground surface, and a data transmitter. The housing includes at least one detector arranged to enable a parameter of the tire to be assessed as the tire passes over the housing. The data transmission gateway is structured to transmit data between the first and second individual modules and a remote database. The collaboration device is structured to enable data from the first individual module to be used collaboratively with data from the second individual module.

Abstract: The invention relates to a method for predicting the speed of a driver driving a vehicle, comprising the following steps: the speed of the driver is measured in a first driving area, this measured speed is compared with a set of speed profiles, each profile corresponding to a predetermined category of driver, on the basis of the result of this comparison, the relevant category for the vehicle driver is selected, and the speed of the driver in a second driving area is predicted on the basis of the reference profile of the selected category. The invention also relates to a method for determining speed profiles for a prediction method according to the invention.

Abstract: A speed evaluation system is provided for assessing a speed of a vehicle. The speed evaluation system includes a wear measurement system, which assesses a state of a tire of the vehicle. The wear measurement system includes a casing placed on a ground surface. The speed evaluation system further includes a timing device that determines at least two instants of passage of the vehicle over two distinct or non-distinct points of passage of the casing of the wear measurement system, and a processor that calculates, as a function of the instants of passage and of dimensional data of the casing and/or dimensional data of the vehicle, a speed of passage of the vehicle over the casing. A method of implementing the speed evaluation system also is provided.

Abstract: A method is provided for measuring a thickness of a layer of rubber-like material. The layer of rubber-like material includes a free face in contact with air and a face joined to an adjacent reinforcement made of elements electrically insulated from one another. Each of the elements includes at least one hysteretic material having a magnetic permeability greater than the magnetic permeability of air. According to the method, a sensitive element, which emits an alternating magnetic field, is brought towards the layer of rubber-like material whose thickness is to be measured, hysteretic losses in the adjacent reinforcement are measured at terminals of the sensitive element, and a thickness of the layer of rubber-like material is evaluated based on the hysteretic losses.

Abstract: A system, which is structured to evaluate a condition of a tire, includes a housing, a tire-wear detector, a tire-presence detector, and an electronic activator. The housing, when the system is deployed, is placed on a ground surface. The tire-presence detector detects a presence of a tire on the housing. The electronic activator activates the tire-wear detector when the tire-presence detector detects the presence of the tire on the housing. The tire-wear detector, when activated, detects a wear condition of the tire when the tire passes over the housing.
