Definitions

  • the present invention concerns a method and a device for establishing a wireless communication between vehicles and communication equipment along the road.
  • the invention is designed in the first place for exchanging data between a vehicle and a transmitting station and/or receiving station along the road, among others data related to toll driving.
  • the present invention concerns a method and device for establishing such a communication which does not have the above-mentioned disadvantage, in other words which allow for a two-way communication which, even with a transmission and receiving range expending over a very short distance, for example a few metres, makes it possible to have a very reliable data exchange between a module in a car, in particular a riding car, and receiving equipment erected along the road in a very short time.
  • a system for realizing a two-way communication with vehicles is described in EP 0.328.836.
  • the present invention aims an improved system.
  • the invention in the first place concerns a method for establishing a wireless communication between vehicles and communication equipment erected along the road, in particular a communication between one or several modules provided to the respective vehicles and communication equipment along the road, characterized in that use is made for the communication of the "direct sequence spread spectrum” principle, also called the “direct access broad spectrum” principle, whereby several modules of such vehicles can simultaneously communicate with the above-mentioned communication equipment on one and the same frequency band, and whereby each communicating module is distinguished from the other ones to this end on the basis of an allowed code, said code being a pseudo arbitrary code.
  • the use of what is called the "direct sequence spread spectrum” principle offers the advantage that a large number of communication links can be simultaneously established with the modules of several passing vehicles.
  • Another major advantage of applying the "direct sequence spread spectrum” principle for such a communication consists in that a good communication can be established with very great certainty, in other words a communication whereby all the required information is transmitted, even when the vehicles pass at a very high speed and thus are situated within the range of the equipment used for merely some tenths of a second.
  • the data to be transmitted are coded very redundantly by means of the above-mentioned code, so that even a partial loss of the transmission is compensated by the redundancy of the data.
  • a two-way communication is established to this end.
  • DSRC microwave band for the above-mentioned frequency band, which is situated at about 5.3 Gigahertz.
  • the content of the communication will be secured, in particular by cryptographically transforming it so as to allow for authentication of the souce and/or encryption of the data.
  • the communication equipment along the road will be mobile, in particular it will be equipment which can be moved and/or wheeled, so that it can be easily used in different places.
  • the invention also concerns a device for realizing the above-mentioned method, characterized in that it consists of the combination of a plurality of modules which are intended to be built in in vehicles on the one hand, and communication equipment which is intended to be erected along the road on the other hand, whereby these modules and this communication equipment are provided with electronics which make it possible for the communication equipment to communicate with the modules situated within the transmission and receiving range of said communication equipment by means of a wireless connection at short distance, such by means of a communication making use of the "direct sequence spread spectrum” principle, also called “direct access broad spectrum” principle, and whereby the electronics are distinguishing the communicating modules from each other on the basis of an alloted pseudo arbitrary code.
  • the invention concerns a device 1 for establishing a wireless communication, in particular a two-way communication 2, between vehicles 3 which are situated on a road 4, and communication equipment 5 which is erected along the road 4, for example on the side thereof.
  • the two-way communication 2 is hereby carried out by means of modules 6 which are provided to this end in the vehicles 3.
  • the invention is special in that, on condition that the necessary electronics are provided in the communication equipment 5 and in the modules 6, a communication 2 is established with every vehicle 3, making use of the "direct sequence spread spectrum” principle, also called the “direct access broad spectrum” principle, whereby all modules 6 situated within the range 7 of the transmission and receiving equipment used hereby, can communicate with the above-mentioned communication equipment 5 on one and the same frequency band, as every communicating module 6 is distinguished from another one on the basis of the allotted code 8.
  • the necessary data can be transmitted in a very short time, so that also very fast vehicles 3, which are merely present within the range 7 for a fraction of a second, can be intercepted in the case of toll driving.
  • the different modules can be easily distinguished, in other words can be easily identified.
  • modules 6 are not necessarily independent units which are built in in the vehicles 3, but that they can also be electronic circuits which are part of the onboard computer or such of the vehicles 3 concerned.

Claims (8)

  1. Procédé pour établir une communication sans fil entre des véhicules et un équipement de communication érigé le long de la route, en particulier une communication (2) entre un ou plusieurs modules (6) dont sont munis les véhicules respectifs (3) et l'équipement de communication (5) le long de la route (4), caractérisé en ce qu'on fait usage, pour la communication (2), du principe "avec étalement du spectre en séquence directe", que l'on désigne également par l'expression proncipe "à large spectre à accès direct", par lequel plusieurs modules (6) desdits véhicules (3) peuvent communiquer de manière simultanée avec l'équipement de communication susmentionné (5) sur une seule et même bande de fréquence, et par lequel chaque module de communication (6) se distingue des autres à cet effet sur base d'un code alloué (8), ledit code étant un code pseudo-arbitraire.
  2. Procédé selon la revendication 1, caractérisé en ce qu'on établit une communication bidirectionnelle (2) à l'aide du principe susmentionné.
  3. Procédé selon l'une quelconque des revendications précédentes, caractérisé en ce que, pour la bande de fréquences susmentionnées, on fait usage de ce que l'on appelle la "bande hyperfréquence pour la communication dédiée à courte distance (DSRC)" qui est située à 5,8 GHz.
  4. Procédé selon l'une quelconque des revendications précédentes, caractérisé en ce que le contenu des communications (2) est sécurisé.
  5. Procédé selon la revendication 4, caractérisé en ce que le contenu des communications (2) est sécurisé via une transformation cryptographique.
  6. Procédé selon l'une quelconque des revendications précédentes, caractérisé en ce que l'équipement de communication (5) érigé le long de la route (4) est mobile.
  7. Procédé selon l'une quelconque des revendications précédentes, caractérisé en ce qu'on l'utilise pour des données de transmission lors d'une circulation sur une route à péage.
  8. Dispositif pour la mise en oeuvre du procédé selon la revendication 1, caractérisé en ce qu'il est constitué par la combinaison de plusieurs modules (6) qui sont destinés à être montés dans des véhicules (3) d'une part, et par un équipement de communication (5) qui est destiné à être dressé le long de la route (4) d'autre part, par lequel ces modules (6) et cet équipement de communication (5) sont équipés de composants électroniques qui permettent à l'équipement de communication (5) d'établir une communication avec les modules (6) situés dans la portée de transmission et de réception (7) dudit équipement de communication (5) à l'aide d'une connexion sans fil à courte distance, par exemple à l'aide d'une communication (2) faisant usage du principe de "spectre de dispersion à séquence en continu", que l'on désigne également par l'expression "large spectre à accès en continu", et par lequel les composants électroniques opèrent une distinction entre les modules de communication (6) sur base d'un code alloué pseudo-arbitraire (8).
