Definitions

  • the present invention relates to the general field of broadcasting alert and safety messages on a road, to and from vehicles traveling on said axis.
  • the patent US4764978 describes a system for transmitting information transmitted by emergency vehicles to vehicles traveling on the road network. These messages are broadcast on the AM and FM frequencies to be received on the car radio.
  • the patent French FR2718404 describes a method and a device for transmitting, from one road vehicle to another and by radio means, information relating to road safety.
  • This method allows a vehicle on the one hand to send, through a low power radio transmitter information to other vehicles within a radius of a few hundred meters, and secondly to automatically receive the information issued by d ' other vehicles, and activate an alert system allowing the driver to easily interpret the information and to know the nature of the danger he will encounter (sound or optical system).
  • the device thus makes it possible to warn drivers arriving in a potentially dangerous zone, and thus to encourage them to slow down in order to avoid chain accidents due to surprise and speed.
  • Another US patent US4403208 describes a system for transmitting alarms or warning signals between two vehicles by transmitting a limited range radiofrequency signal.
  • the patent European EP0817151 discloses a method for individually notifying traffic incidents by means of an onboard device and a stationary device using an incident message broadcasting type broadcast with local selection based on incident messages primary (M1).
  • M1 primary incident message
  • M2 Secondary incident messages
  • CA incident
  • Each receiving device that receives a secondary incident message derives from the received incident coordinates (CA) and its own coordinates (C1, C2, C3) and from their determined modifications a decision concerning the reconciliation or the non-reconciliation of the vehicle of this incident, and in case of reconciliation of the incident, delivers a message (A).
  • the patent French FR2629404 proposes a car alarm installation which comprises means for creating an alarm trigger signal, which means can be realized by a shock sensor or by a manual switch, an alarm emitting means by electromagnetic or ultrasonic waves, means for receiving the alarm signals and warning means.
  • the shock sensor produces a signal that triggers the transmission of an alarm, for example, by means of an antenna positioned on the car. All other automobiles, within a maximum distance, equipped with a compatible warning system receive these alarm signals operating warning means in these automobiles.
  • the patent French 9614682 presents an efficient realization of emergency communication between vehicles, using a single frequency and time sharing in recurring cycles, setting the sampling period. Each cycle is divided into slices, the number of slices determining the instantaneous system capacity (without collision). An automatic but selective relaying function is proposed to extend the scope in multi-hop, from cycle to cycle. The overall synchronization is provided on a statistical mode, which makes it possible to overcome the topology and any reference clock.
  • the patent French FR2831760 describes a similar time-sharing device, fully backed by a fixed access point infrastructure, that controls and orchestrates the exchange between vehicles and infrastructure. Relaying functions are provided to circumvent the effects of masks between vehicles.
  • the system integrates the protocols of the Internet world, both for security services (automatic driving or assistance) for logistics services or comfort.
  • the document US-2002/0036571 discloses a vehicle information system of conventional types for exchanging information about the vehicle position, traffic information or the like using specific equipment upon request of the vehicle.
  • European EP-1150266 also describes a system for distributing information about the road surface condition. This application briefly describes a device for transmitting information to a vehicle.
  • the European patent EPA1286507 describes a vehicle-vehicle communication system in Ad-hoc mode or more precisely mesh (mesh) from fixed access points (GW). It gives the nearest access point a role of relay station to vehicles in range.
  • the patent European EP0982698 A2 describes a geographic discrimination broadcast system for traffic control and alert messages that uses a distributed server infrastructure and a chain of base stations with joined coverage.

  • MTNET industrial product from PROMETHEUS MANET demonstrators and DRIVE
  • the vectors VIGILANT and IVHW working in competition and in simple jump (point to point).
  • Such systems focused on local security, want to be independent of any fixed infrastructure, but overall security encourages the principle of routing to a possible infrastructure point, for concerted actions with the treatment centers.
  • One of the interests of MTNET relaying is to facilitate such routing.
  • the ARCOS program introduces a front-end communications architecture, which enables seamless cooperation between vehicle-vehicle and vehicle-infrastructure vectors.
  • the future SARI program plans to generalize vehicle-vehicle solutions of the MTNET or IVHW type to fixed access to the infrastructure.
  • the candidate technologies are still in the experimental stage.
  • the International Working Groups (ANSI, ETSI, ISO) on CALM (Continuous Air Interface for Long and Medium Distance) partially reflect the principles of these programs and solutions for a 5.9 GHz application.

  • real-time performance is superabundant compared to road requirements, while the ranges are rather below.
  • EP-0994449 which describes a communication system between infrastructure and vehicles combining radio broadcast means and individual bidirectional links with the vehicle. These individual links are independent of the broadcasting means, the base stations being distinct from the broadcasting stations. In this solution, it is not expected that bidirectional links can be established directly between the vehicles, without going through the infrastructure.
  • the object of the present invention is to propose a reliable solution, to broadcast an alert effectively even when a number Reduced only vehicles is equipped with specific equipment, and whose costs of equipment or re-equipment infrastructure are moderate, requiring a minimum of adaptation of existing infrastructure.
