Definitions

  • the invention relates to a system for automated communication between a plurality of motor vehicles according to the The preamble of claim 1 and a method of automated Communication between a variety of motor vehicles according to the preamble of claim 13.
  • WO 98/09264 proposes in participating motor vehicles communication means to provide for sending and receiving a message, wherein in one manual or critical situation in a motor vehicle automatically the sending of the message is activated.
  • receiving end Motor vehicles can use the signal strength of the message assess their relevance.
  • this system works autonomously and thus, neither operating costs, nor will one appropriate external infrastructure needed.
  • that is Assessment of the relevance of a received message by the Use only the signal strength inaccurate and occur For example, problems with parallel roads. Again, a special vehicle equipment is necessary.
  • the generic EP 0 201 461 B1 discloses a system for automated communication between a variety of Motor vehicles, taking in each of the participating motor vehicles a means of communication for sending and receiving messages, Detector and / or activator for generating a message, display means for outputting information and an electronic processing and control means provided are.
  • the processing and control means for a continuous re-sending one of the communication means received message, as well as continue to run Sending a message through the means of communication during the period of activation of the detector means, and also a possible output of a message as information by the display means.
  • This system works as well autonomous and therefore no operating costs are, or will be a corresponding external infrastructure is needed.
  • Each one of the warning process participating motor vehicles has a means of communication for sending and receiving messages, where for selective warning the messages over a distance of 3 km are sent or received.
  • the messages include while information about the position and the direction of travel from a navigation system of the warning motor vehicle.
  • US 6252520 B1 relates to automated system Communication between a variety of motor vehicles, each having a state sensor comprising a large Number of sensors. This allows monitoring the approach of these motor vehicles with each other. When a Minimum distance is below, takes place in the participating Cars a warning. When involved in a single one of If no warning is given to motor vehicles, then one will such warning is controlled by the system.
  • Position chain e.g. positions determined by a satellite navigation receiver
  • the receiving Motor vehicle can by comparing its own Position chain with the position chain of the sending Motor vehicle check that of both motor vehicles previously traveled routes are identical and whether the sending vehicle before (downstream) or behind (upstream) from the receiving motor vehicle.
  • the result this comparison is expressed by a measure of relevance, and a warning is only necessary if this relevance measure is big enough.
  • no navigation system i.e. no digital road map needed.
  • the object of the invention is a system and a method for automated communication between a variety of Specify motor vehicles, which is a safe assessment allow if a received warning message for a motor vehicle relevant, and which at the same time as special little effort can be realized, so as possible ensure rapid dissemination in road traffic.

  • Activation and or display means are each additionally provided in different form, either integrated in the ETC unit and / or connected to it.
  • the ETC unit already has in the vehicle via controls, which are used as activating agents can be. It is advantageous, however, that as an activating agent the hazard warning light switch is used. There this usually when approaching a danger point is pressed, the driver must thus perform only one hand.
  • the processing and control resending a message received from the communication medium Message only causes if the distance difference between the current position of the receiving motor vehicle and the position used in the message is less than one determinable limit. This is the passing of the Report only within a relevant geographic area ensured.
  • processing and control means resending one of the means of communication received message only causes if the time difference between the time of receipt of the message and the current one Time is less than a definable limit. So be only current news passed.
  • the output of a message is effected by the display means only when the motor vehicle moves to the position used in the message and / or the distance difference between the current one Position and the position used in the message smaller is a definable limit. This mechanism presents sure that the driver is only given such messages become relevant to him.
  • further activation means such as control buttons for special situations and / or values of vehicle sensors.
  • a detector for taking situational data provided, in addition, in the event of the occurrence of predetermined Situational data automatically generates a message becomes.
  • a message is output as information if as a display means a display and / or a voice output is provided.
  • a display means a display and / or a voice output is provided.
  • These can be integrated into the ETC unit and / or become it used independent components. So you can already in the car existing display means are used, e.g. one Color display. Alternatively, a retrofit can be provided.
  • the connection of the ETC unit with such display means becomes either wired, e.g. via a vehicle-based data network, or wireless, e.g. via short-range communication, executed.
  • on the display means also issued be generated, received and / or sent a message was, if the driver so wishes.
  • a comprises Message the position of the motor vehicle in the generation of Report. This is an assignment of the danger point in Receiving motor vehicle possible.
  • a message can be used more universally if it additionally includes the generation time point and / or a travel speed, for example an averaged or an instantaneous travel speed in the generation of the message, and / or a quality measure characterizing the accuracy of the position information.
  • a position information from the receiving motor vehicle can be determined for a received message. For this purpose, for example, a distance traveled approximately to (t 1 : time of receipt of the message, t 2 : time of retransmission, v: driving speed); be set.
  • a message additionally information about comprising the activation agent generating the message.
  • These Information can be taken into account during further processing of the message and / or the driver on the display means additionally displayed.
  • a more detailed assessment of a received message by a Receiving motor vehicle is achieved by the one received message before re-sending in addition to the Re-transmission time and / or a speed of travel added to the receiving and re-emitting motor vehicle becomes. This allows the message received the modified message Motor vehicle the relevance and / or relevance of the received To judge the message even better.
