摘要： A system for measuring a thickness of a layer of rubber material of a tire includes a sensor. The layer includes a joined face, which is joined to an adjacent metal reinforcement, and a free face, which is in contact with air. The sensor, which measures a distance d between the joined face and the free face, includes a source of a static magnetic field and a sensitive element whose output signal is a function of a level of a local magnetic field. The sensor is positioned in such a way that a magnetic field strength measured by the sensitive element varies when the distance d decreases.

摘要： A system for evaluating a condition of a tire includes a housing placed on a ground surface, a wear detector that detects a wear condition of the tire when the tire passes over the housing, a tire presence detector that detects a presence of the tire over the housing, and an electronic activator that activates the wear detector during detection of the presence of the tire by the tire presence detector.

摘要： 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.

摘要： A method for detecting an underflation state of a tire fitted on a vehicle is provided. The method includes determining a first contact patch measurement of a first tire fitted on the vehicle, determining a second contact patch measurement of a second tire fitted on the vehicle, and comparing the first and second contact patch measurements. An underinflation situation is inferred if a difference between the first and second contact patch measurements is greater than a predetermined signalling threshold.

摘要： A method for providing a service linked to the condition and/or behavior of a vehicle and/or of a tire comprises the following steps: when a vehicle passes a road infrastructure equipped with a system for assessing the condition of a vehicle, determining an identifier of the vehicle and/or of a tire of the vehicle, at the same time, determining at least one parameter representative of the condition of the vehicle and/or of a component of the vehicle, transmitting the determined data to a remote data server, from the identification data, retrieving external data concerning the vehicle and/or the tire and/or the running conditions, combining the determined information with the external data such as to determine a relevant indicator concerning the condition and/or the behavior of a vehicle, and transmitting the relevant indicator to a provider of a service linked to the condition and/or to the behavior of a vehicle and/or of a tire.

摘要： 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.

摘要： A system for counting wheel revolutions made by a wheel of a vehicle, the system including an electronic counter, a transmitter, a housing, and a connector. The electronic counter counts a number of wheel revolutions made by the wheel. The transmitter transmits data from the electronic counter to a remote database. The housing houses the electronic counter. The connector removably attaches the housing to a nut anti-loosening device installed on the wheel.

摘要： 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.
