AI Technical Summary

Technical Problem

Existing lively transport systems face challenges in efficiently transitioning vehicles from a limited driverless mode to an unrestricted driverless mode, especially after restarts or maintenance, due to uncertainties about ghost trains and the need for manual intervention.

Method used

A procedure for operating a lively transport system that allows a track-bound vehicle to transition from a limited driverless mode to an unrestricted driverless mode by using a route-side safety tax device to initiate remote control signals for a location and ghost train acquisition process, ensuring safe operation without manual intervention.

Benefits of technology

Enables reliable and efficient transition to unrestricted driverless operation, reducing the need for manual intervention and enhancing safety by ensuring accurate detection of ghost trains and vehicle positioning.

Abstract

The invention relates to a method for operating a track-bound traffic system (1; 101), wherein - a track-side safety controller (60) transmits a request (Anf), to a track-side controller (40), to allow a track-bound vehicle (50) to carry out a driverless driving operation in a restricted driverless driving mode using the safety controller (60), - in response to the request (Anf), the track-side controller (40) outputs a permission (Erl) corresponding to the request (Anf), - in the event of a permission (Erl) together with a conversion of the track-side safety controller (60) from an inactive control mode to an active control mode, the track-side safety controller (60) prompts the vehicle (50), using remote control signals (FstS), so as to start to drive in the restricted driverless driving mode and continue the drive in order to carry out a locating and ghost train detection process in the restricted driverless driving mode as long as the track-side safety controller (60) is in the active control mode and as long as the locating and ghost train detection process lasts for the vehicle (50), and - after the locating and ghost train detection process is successfully concluded, the vehicle (50) is converted to an unrestricted driverless driving mode, thus invalidating the effect of the remote control signals (FstS) on the movement of the vehicle (50).
