Definitions

  • the invention relates to a method for the automatic vehicle-autonomous detection of traffic jams and a device for carrying out this method. It is therefore an automatic determination of a measure for assessing the traffic-dependent accessibility of roads.
  • DE 43 21 437 A1 discloses a method for the automatic vehicle-autonomous detection of traffic information, i.e. Travel information entered in the vehicle is processed with traffic information acquired via radio and with an on-board traffic database.
  • the recording and description of the traffic situation is an essential task in the area of traffic telematics, which aims to rectify and avoid situations with traffic congestion as far as possible by appropriately anticipating redirection of road users onto less congested roads.
  • stationary detection devices e.g. beacons, induction loops or similar
  • This is not only associated with very high costs for the creation and maintenance of the required infrastructure, but also has the disadvantage that these facilities only have a locally extremely narrow range of use due to the system. The installation of a huge number of detection devices is therefore necessary for a comprehensive traffic situation detection.
  • a problem with the "floating probes" is that the continuous transmission of the current speed of a large number of vehicles is an extremely heavy burden on the transmission channels of the communication device and, moreover, constitutes a significant cost factor when using a fee-based communication system. This is to be seen against the background that predominantly information is transmitted that does not really provide any new information. It would therefore be useful if the transmission of information could at least be largely restricted to periods of time in which critical traffic situations are forming, have already started or are disappearing. One should therefore be able to determine the time periods in which interesting changes in road traffic occur. This could, as has also already become known, be made possible by the fact that the relevant traffic situation information is provided by people in the "floating probes" (so-called congestion detectors) as required.
  • the object of the invention is therefore to provide a method and a device for carrying it out which is automatic, that is to say independent of persons Vehicle-autonomous detection of traffic congestion enables, so that depending on it a targeted transmission of really important traffic information can take place.
  • the invention provides that the speed of a vehicle in a sample vehicle fleet is continuously recorded and passed to an in-vehicle classification device.
  • This classifying device has access to speed classes which are stored in a storage device for default values, preferably depending on the road type.
  • the default values can be stored as fixed values or as dynamically variable quantities. For example, the specification could be made when the respective device is switched on and the subsequent initialization. It is particularly advantageous to be able to change the default values from a central station as required (e.g. using mobile radio).
  • the classifying device assigns the detected value of the current speed to one of these speed classes.
  • this assignment is made to speed classes, which are defined by predefined limit values.
  • At least three speed classes are expediently provided.
  • the limits of the speed classes should be determined depending on the type of road. For example, while a multiple division in the lower speed range makes sense for urban streets, the middle and upper speed range should also be considered as a separate class for motorways, for example.
  • the functional block example shown in FIG. 2 for a device for carrying out the method according to the invention has the speed detection device 1, the data output of which is connected to a classifying device 2 in which the continuously measured instantaneous vehicle speeds are assigned to a speed class.
  • the default values for these speed classes can be classified by the classifying device 2, preferably as Non-volatile memory remove trained storage device 4 for speed classes.
  • the data output of the classification device 2 is connected to the data input of an integration device 3.
  • the result of the integration is sent to an evaluation device 5, which supplies a stowage dimension representative of the respective traffic situation in the area of the vehicle in question in the sample vehicle fleet, preferably in the form of a probability value for the occurrence of the "traffic jam" event.
  • this stowage dimension enables the device according to the invention to automatically recognize critical or critical traffic situations without any manual intervention and to activate, for example, a communication device 6, with the aid of which situation-related transmission of important traffic situation information to a corresponding collection point can take place.
  • the communication device can be deactivated again. This can be the case, for example, if a vehicle is in a traffic jam for a long time, that is to say the size of the traffic jam practically does not change. However, it can be of particular interest to recognize the point in time when this vehicle leaves the stowage area again.
  • the device according to the invention can be equipped with a position determination device (not shown) (for example on the basis of navigation satellites).
  • the method according to the invention enables a completely automatic decentralized, ie vehicle-autonomous, determination of a representative measure of the "traffic jam" situation with intermediate gradations that can be refined as required up to the "free travel” situation in a very simple manner.
  • the necessary In-vehicle device is very simple and inexpensive to manufacture from standard components.
  • the invention makes it possible to keep the scope of the communication requirements for a sample vehicle fleet required for meaningful traffic situation detection to a minimum, since automatic autonomous detection of situations in which traffic situation information should be transmitted to a data collection point is possible with sufficient reliability.
