Definitions

  • route networks in particular railway route networks, on the basis of vehicles which determine their position regularly or irregularly and transmit it to a central facility
  • the central facility can control and manage the traffic in the route network on the basis of information obtained.
  • the problem can arise that the central device does not know all the vehicles traveling in the route network, for example if a vehicle does not transmit its positions due to a defect.
  • the invention is based on the object of specifying a method for recognizing a vehicle driving directly in front of a vehicle in a predetermined route section of a route.
  • a route section monitoring device which monitors a given route section for whether it is occupied or unoccupied, generates a release signal as soon as the route section becomes vehicle-free again after a previous occupied state, using a route-side time indication indicating the time of the release the route section monitoring device, location information of the preceding vehicle, which has been determined after leaving the route section by the preceding vehicle at a location determination time, a vehicle-side time indication indicating the location determination time and a speed indication indicating the speed of the vehicle driving ahead, the location of the vehicle end of the preceding vehicle at the time the route section is cleared, the distance between the section end of the route section and the calculated location of the vehicle end is determined, and the distance is used to check whether the vehicle in front is traveling directly behind a vehicle.
  • a major advantage of the method according to the invention is that a vehicle traveling behind, which itself does not emit any location information and is therefore not "visible” to a higher-level central device, can nevertheless be known by location information of the vehicle driving in front of this "invisible” vehicle and signals from a section monitoring device are evaluated in the manner indicated.
  • a detection signal is generated which indicates a vehicle traveling directly behind if the distance between the end of the section of the section and the calculated location of the end of the vehicle is greater than a predetermined trigger length.

  • the vehicle in front preferably transmits as location information a location information directly indicating the location of the vehicle end to the central device.
  • the location information of the vehicle in front relates to the vehicle start and the location of the vehicle end is determined on the basis of the location information related to the vehicle start and a length indicating the length of the vehicle in front.
  • the central device is preferably a signal box, a train protection system or a control center.
  • Checking whether a vehicle is driving directly behind the vehicle in front can alternatively or additionally can also be carried out by a test facility of the vehicle in front.
  • the invention also relates to a test device for recognizing a vehicle immediately following a vehicle traveling ahead in a predetermined route section.
  • the test device is designed in such a way that it uses a time indication indicating the point in time when the route section becomes free, a location information of the preceding vehicle, which was determined by the preceding vehicle at a location determination time after leaving the route section is, a vehicle-side time indication indicating the location determination time and a speed indication indicating the speed of the preceding vehicle, the location of the vehicle end of the preceding vehicle at the time the route section becomes free, the distance between the section end of the route section and the determined calculated location of the vehicle end and uses the distance to check whether the vehicle in front is driving directly behind a vehicle.
  • the test device has a computer and a memory in which an operating program is stored which, when executed by the computer, prompts the latter to use a time information indicating the point in time at which the section of the route becomes free, a location information of the preceding vehicle, which was determined after leaving the route section by the preceding vehicle at a location determination time, a vehicle-side time indication indicating the location determination time and a speed indicator indicating the speed of the preceding vehicle indication of the speed, calculating the location of the vehicle end of the vehicle in front at the time the route section becomes free, determining the distance between the segment end of the route section and the calculated location of the vehicle end, and using the distance to check whether the vehicle in front has a vehicle telbar follows.
