This makes it advantageous possible, the device according to the invention both above ground as well as underground for track-guided vehicles Presentation of location-dependent information use.
  • Another advantage is that the track-guided No changes need to be made to the vehicles to use the device according to the invention. It’s because of that Measuring principle using acceleration sensors and possibly a rotation rate sensor that has no connection to a component in the powertrain of the track-guided Vehicle or to an external transmitter.
  • an additional one Yaw rate sensor is used to measure angular acceleration, that the vehicle experiences, to measure and thereby Determine height difference.
  • the measured acceleration values directly with stored acceleration values are compared to determine the location of the track-guided vehicle. This enables a very simple evaluation of the measurement.

To the To carry out a comparison, the processor 2 therefore proceeds from last value stored in memory 4, with the still no comparison was made.
  • the measured in the further course of time Acceleration value is as long as with the following, in Memory 4 values compared until the Difference falls below a predetermined threshold. Then the error is so small that from a match is spoken.
  • the memory 4 can not be here writable memory to be executed, since in vehicles for public transport, the routes for not change certain vehicles and, if so, the Case, then simply the appropriate one Storage medium is replaced. Offer as storage media CD-ROMs or DVDs, but they are also rewritable hard disk space possible.
  • the measured values stored in the memory 4 are either as acceleration values. Then the comparison is very good simple, or the values stored in memory 4 are as speed values. This enables easy Determination of the route profile.
  • the speedometer or one other speed measurements are made during departure the route used to determine this departure schedule.
