Definitions

  • the invention relates to a method for transmitting information and Visualization of sensed vehicle data and a Traffic information system.
  • Radio information transmission by others is also known Road users with regard to switching on lamps (DE 42 02 489 A1, DE 196 24 116 C1), accident report (DE 40 04816 A1) and distance to vehicle in front (DE 39 15 466 A1 and DE 31 38 377 A1). It is disadvantageous that only special data are used in each of these methods that are insufficient to address the main causes of Traffic disruptions, namely inappropriate driving behavior, too fight. In addition, there is particularly in the case of infrared transmission Problem that following vehicles in the "shadow" of vehicles, for example trucks that do Information transmission system can not have, drive and thus the information chain for the following vehicles is interrupted. In addition, false alarms can easily occur, especially in city traffic come through a turn signal if this is a warning signal is understood and therefore in appropriately equipped vehicles the hazard warning lights are switched on automatically.
  • the invention is based, a method and a task Traffic information system indicate that a much higher Allows traffic density and prevents traffic jams and accidents.
  • a preventive Traffic flow control results in particular from the fact that the controlling Component, namely humans and also vehicle electronics, in the Control process. This is achieved in that every vehicle or driver continuously foresighted Information is provided to respond accordingly to be able to. By showing transmitted data in the windscreen of the vehicle is one even in thick fog and when driving at night safe driving possible. In connection with the cellular system of GSM mobile technology is also the problem of disrupting the Information chains through "shadow formation" behind vehicles, especially trucks or buses that are not using this system are equipped, solved. In addition, the process is independent of the Weather. For example, with every line of sight there is information ahead in terms of acceleration or braking Vehicles available. This is a more customized response of the driver of a following vehicle possible. oscillating Vehicle flows and congestion as well as the risk of accidents curbed.
  • the features of claim 3 can be a simple Realize guidance. A e.g. in the lower left corner of the The windshield of the route is also very helpful Visualization of further data that symbolizes the course of the route can be overlaid.
  • Such route actions can, for example be: actuation of the windscreen wiper, the fog lamp, the brake as well as average speed, traffic jam warning etc. If a The vehicle in front is braked and the wheels react different, it can be a result of black ice or wet road, so that conclusions about the road conditions are possible are.
  • the route follows in a simple way through sensory Detection of steering movements or the angular position of the front wheels from e.g. 20 or 100 etc. of vehicles in front.
  • the vehicles can also be used as quasi Relay stations for transmitting information to vehicles operating on driving in the opposite lane can be used.
  • the transmission security can be rated as very high since the information on different ways are spread. An unwanted one Transfer of information or influencing the Oncoming traffic can be avoided, for example, by using a compass Determination of the rough direction of travel is used and the resulting derived data used to select irrelevant information become. It would also be conceivable to have a variable, directed one from the outset Radiation corresponding to the curve shape using array antennas provided.
  • the transmission power can also be set accordingly.
  • Claim 6 characterizes a traffic information system that the Visualization of information of all kinds, e.g. Average speed, focus of accidents, nearest petrol station, Hotel etc. as well as current traffic, road condition and weather data made possible by fading into the windscreen of the vehicle.
  • additional base stations are in the according to claim 7 Mobile network integrated. These base stations can do this in particular serve, statistics depending on the time of day, day of the week etc. to create the traffic density, the (average) speed, the Determine the probability of accidents and other data and if necessary, to send to road users. Furthermore can Marking of accident focal points, Speed limit indicators and other signal systems the determined statistical data are controlled. Base stations can also used to translate the To create information in other languages for road users to signal the next gas station, the next hotel and the like as well as relaying information to the police and even around as "Electronic mailboxes" with messages or information for e.g. To serve goods traffic, convoy vehicles, etc.
  • Claim 8 characterizes a simple embodiment with respect to System components for implementing a traffic information system of the type described above.
  • the front screen overlay means an interface to the driver information direct control of the vehicle electronics can be provided.
  • the lighting system or the wiper system automatically be put into operation based on received signals.
  • Figure 1 is a schematic diagram to illustrate the method and Figure 2 system components for information processing in vehicles.
  • FIG. 1 a highway scenario is shown, vehicles 1a to 1h in the direction of travel B and vehicles 2a to 2e in the opposite Drive in direction A.
  • the arrows symbolize the direction of information transmission, namely from the preceding vehicle to the following vehicle.
  • Additional radio links Y can move between vehicles in different directions - in Embodiment between 1 e and 2c -, between vehicles different lanes in the same direction - in Embodiment between 1b and 1g -, between vehicles and Fixed stations 3a, 3b - in the exemplary embodiment between the vehicle 2e and the base station 3a and between the vehicle 1c and the base station 3b - and between several fixed stations 3a and 3b.
  • the base stations 3a and 3b can be used to Forward traffic information to the police, statistics about this To collect route section, vehicle density and To determine average speeds along signal lines Route e.g. regarding accident focus, speed limits etc. to control and possibly information about the next Petrol station, the next hotel etc. to the passing vehicles 1a to 1h and 2a to 2e.
  • the vehicles 1a to 1h and 2a to 2e in turn transmit vehicle data determined by sensors of all kinds, for example the current speed or actions like Accelerate, brake, wipers or fog lights on or off as well as steering wheel movements or angle information of the front wheel axle.
  • vehicle data determined by sensors of all kinds, for example the current speed or actions like Accelerate, brake, wipers or fog lights on or off as well as steering wheel movements or angle information of the front wheel axle.
  • the latter information is used as an input signal to display a predicted route in e.g. the lower left corner of the Windshield of following vehicles used.
  • the vehicles 1a to 1 h and 2a to 2e are for this purpose with a computer 4 (Figure 2) Preparation of all information equipped, in particular for Route determination based on the data available at certain points Interpolation can be implemented in complete route representations.
  • the Vehicle data and vehicle actions listed above as examples are superimposed on this route in an ergonomically favorable manner.
  • This weather-independent procedure simplifies a more adapted one Driving style based on traffic, weather and road conditions current events, for example accidents, road closures or Construction sites.
  • FIG. 2 shows an embodiment of the in the vehicle (1a to 1h, 2a to 2e) arranged essential system components for realizing a traffic information system according to the invention.
  • the centerpiece is a computer 4, with a receiving and transmitting device 5, a converter 6 with connected vehicle sensors 7 for bilateral Information transfer is connected.
  • an interface 8 is connected, which is used to control Front screen insertion means 9 is used.
  • the receiving and transmitting device 5 is with Receiving or transmitting antennas 11 connected, which are predetermined Can have directional characteristics. For example, these antennas 11 be designed as array antennas.
  • the computer 4 is preferably used also for speed-dependent selection of the interface 8 information to be forwarded to the front disk display 9. This can be divided into stored priority classes beforehand.
  • the invention is not limited to the above Embodiment. Rather, a number of variants are conceivable which, even in the case of a fundamentally different type of execution, from those in Make use of the characteristics of the claims.
