Definitions
- the present invention relates to a system for evaluating the state of a vehicle installed on or near a road infrastructure. More specifically, the invention relates to such a system comprising a subsystem for measuring the state of a tire.
- a subsystem measuring the state of a tire is for example, but not limited to, a system for detecting the wear of a tire, a system for detecting the pressure of a tire, or a system for measuring the speed of a tire.
- the present invention aims to provide a system, in particular for use by fleet managers of vehicles, which can be part of a more comprehensive system for diagnosing the state of a vehicle and its tires.
- a system in particular for use by fleet managers of vehicles, which can be part of a more comprehensive system for diagnosing the state of a vehicle and its tires.
- none of the known systems allows, in the state, a cross-reference of different information concerning the vehicle and its tires.
- the present invention is therefore to overcome this disadvantage by providing a system with easier conditions of use.
- the invention proposes a system for evaluating the state of a vehicle, the system comprising:
- a subsystem for measuring the condition of at least one tire of the vehicle is A subsystem for measuring the condition of at least one tire of the vehicle
- the three subsystems being installed in one or more housings intended to be installed on or near a road infrastructure, at least one of the housings being intended to be installed in a constrained driving zone of the road infrastructure.
- road infrastructure and “constrained driving zone” is meant, for example, an infrastructure such as a motorway, and zones of compulsory passage such as a toll lane, an access road to the motorway. , access roads to a service station ...
- an infrastructure such as a car park, with areas of passage required such as the access routes to an underground or aerial car park. a service area or rest area on the edge of a road or highway.
- the constrained driving zone may be a simple traffic lane and / or passage of the area, marked by ground markings and / or physical obstacles.
- the database transmission subsystem may use a pre-existing telecommunications gateway.
- the managers of the motorway networks have information systems on which a large amount of data concerning the weather, the proximity of these information systems makes it possible to use these data to transmit them to a vehicle and / or combine them with the data measured during the passage of the vehicle, for determine value-added information for the driver of the vehicle or for any other service.
- the measurement subsystem and the identification data reading subsystem are advantageously installed in the case located in the vehicle running zone, so that measurements can be made at the moment when the vehicle passes over the case.
- the identification data reading subsystem includes, for example, an RFID reader for reading identifiers stored in RFID chips that can be installed on each of the tires of the vehicle, and / or on the vehicle in question. himself.
- this reader comprises one or more reading antennas, chosen from antennas with linear or circular polarization. Such antennas make it possible to ensure the reading of the RFID chips whatever their location on the vehicle and / or the tires. Indeed, when using a system according to the invention, the positioning of tags or RFID chips on vehicles can not be presumed, any more than the positioning of the vehicle relative to the housing during its passage on said housing .
- antennas and / or RFID readers may for example have antennas and / or RFID readers positioned on each side of the vehicle.
- the subsystem measuring the state of at least one tire of the vehicle is a subsystem measuring the tire wear.
- measurement subsystems that allow the determination of other quantities such as: the shape, surface or length of contact area, the load supported by each tire, the contact pressure in the contact area, or the speed of the vehicle.
- the measurement subsystem comprises at least one sensor included in the group comprising: an eddy current wear sensor, a variable reluctance wear sensor, an optical wear sensor to Laser base, a pressure sensor, a local charge sensor.
- Foucault current sensors or variable reluctance sensors are particularly advantageous for outdoor installation, because they are insensitive to dust and dirt of low thickness, typically less than one millimeter. Such a characteristic is a real advantage in a system according to the invention because the rolling floors of the Toll barriers are usually not cleaned regularly because of access difficulties.
- the system further comprises a data receiving device installed in the vehicle.
- the measured data transmission subsystem it is advantageous for the measured data transmission subsystem to include means for transmitting the data to the data receiving device installed on the vehicle.
- the data measured during the passage of the vehicle can be transmitted not only to a remote database, but also to the vehicle itself, in real time compared to its passage on the measuring system.
- the housing installed in the rolling area is a low-height housing, embedded in the driving floor, for example a concrete floor or concrete.
- Such a housing architecture allows integration into the road without any roughness to come flush the ground. Indeed, some vehicles, such as snow plows for example, can not pass on rolling floors with obstacles.
- the architecture proposed here makes it possible to remedy this problem.
- a toll barrier 40 is provided with:
- the measuring device 30 takes the form of a housing placed on the ground, on which a vehicle is intended to roll. This box also includes the RFID reader 35.
- the housings housing the different subsystems are circular, buried in the ground, so that its upper surface is flat and located parallel to and slightly below the plane of the roadway or in the plane of the roadway.
- the measurement subsystem comprises a unitary sensor, or one or more lines of sensors, for example eddy current sensors or variable reluctance sensors, for measuring the wear at several points of the tire.
- the measurement subsystem comprises a unitary sensor, or one or more lines of pressure sensors installed in the area intended to accommodate the contact area of the tires during taxiing. Thus, it is possible to estimate the pressure of the tires.
- the sensors and the management electronics of the device 30 are powered by the electrical network from the toll barrier 40.
- the RFID reader 35 is provided with one or more RFID reading antennas with linear or circular polarization. These antennas can be arranged at several positions of the road in the direction of circulation in order to be able to capture the RFIDs mounted on the tires more easily.
- said antennas may be distributed over a rolling area up to 5 meters long but preferably 3 meters long or less.
- the RFID chips glued or integrated into the tires 20 and the RFID chip 11 stuck on the vehicle 10 are read by the RFID reader 35 associated with the system. measuring wear 30.
- the data is transmitted to the vehicle 10 by means of the data transmission device 36.
- Either the data is transmitted directly from the device 36 to the device 15 for transmitting and receiving data present on the vehicle 10.
- Either the data is transmitted from the device 36 to a remote database 50 by means of a data transmission device 45 associated with the toll barrier 40. It is specified here that the transmission means 36 and 45 can be made by a single device.
- the data can then be retransmitted to the vehicle 10 by means of the data transmission systems 45 and 15.
- the vehicle 10 is equipped with means of communication with the driver of said vehicle, for the communication of any type of information as previously described in this application.
