  • ETCS Level 2 almost all information is transmitted via Euroradio from the radio control center (RBC) to the vehicle.
  • the RBC Before the RBC can calculate the information necessary for a driving license (MA), the RBC must know exactly where the train is and in which direction it is traveling. The determination of position and direction is the responsibility of the vehicle computer, which transmits this regularly via GSM-R to the route. For the determination, however, reference points on the route are needed. For this Eurobaiisen are used, which are attached, for example, in the exit tracks of stations and at irregular intervals on the open road. Between these reference points, the position is determined odometrically by means of Doppler radar on the traction vehicle floor and Radimpulsgebern on the traction vehicle axles. Partial acceleration sensors are also used.
  • the information on free track sections is determined as in ETCS Level 1 on the stationary track release signal from the interlocking and passed to the line center:

  • the position determination of the rail vehicle 102 can be corrected the more often by means of the odometry balises 104 to 106 the closer the rail vehicle comes to the signal 103.
  • the object of the invention is to avoid the abovementioned disadvantages and, in particular, to provide a cost-efficient solution by means of which part of the balises can be saved.
  • Intervals are arranged along a route section, wherein one of the odometry correction balises is arranged in the direction of travel behind a point or area which marks the end of a driving license.

Abstract

La présente invention propose, en particulier pour le Système européen de commande des trains (ETCS) de niveau 2, de placer une balise de correction d'odométrie pour un tronçon de voie dans le sens de roulement, derrière la fin de l'autorisation de mouvement (EOA). L'avantage est qu'il est possible de se passer d'un grand nombre de balises de correction d'odométrie, qui auraient été par ailleurs nécessaires, et que malgré tout, aucun avertissement inutile n'est donné à un poste de conduite d'un véhicule ferroviaire, et plus précisément aucun processus de freinage inutile n'est effectué.
