  • Patent number: 12311988
    Abstract: A system and method for providing a virtual approach signal restriction upgrade between physical signaling components is presented. In one embodiment, in a CTC type of operation, the use of a virtual signal with signal type functionality to split a block into two or more sections can allow a train currently governed by an approach indication to accelerate on a clear indication if the advance signal indication upgrades. The addition of audio frequency type circuits with the advance signal indication can allow a train to upgrade from a restricting indication to an approach or clear indication, while protecting open HT switches, broken rail, hazards, and follow up moves. The present invention provides a system for allowing trains to upgrade from a “restricting” indication to an “approach” or “clear and accelerate” indication with an upgraded PTC track line for the segment.

  • Patent number: 12179815
    Abstract: A computer implemented method is for determining railway vehicle movement profile type of a railway vehicle movement profile. The railway vehicle movement profile includes a sequence of measured transmitted currents of a transceiver of a track circuit with respect to the time. The method includes obtaining a railway vehicle movement profile, normalizing the railway vehicle movement profile, extracting one or more features from the normalized railway vehicle movement profile, determining the distance of the extracted features with respect to each centroid of a railway vehicle movement profile type determined in a classification process, and assigning the railway vehicle movement profile to the railway vehicle movement profile type with the closest centroid.

  • Patent number: 12168467
    Abstract: A method for energy-optimized operation of a rail vehicle fleet. The fleet includes n rail vehicles, each with a state-influencing system for influencing a vehicle state to generate and/or consume electrical energy and a computer unit trained by machine learning. For every i of 1 to n during operation of the rail vehicle fleet an action to be applied to the state-influencing system of the i-th rail vehicle is selected by the computer unit of the i-th rail vehicle while taking into account at least one target criterion for the i-th rail vehicle and according to vehicle, location, and/or route-related status parameters. The action, when applied to the state-influencing system of the i-th rail vehicle, contributes to the optimization of an electrical total energy balance of the state-influencing systems of the rail vehicle fleet, and the selected action is applied to the state-influencing system of the i-th rail vehicle.

    Abstract: A system may include a sensor that detects positioning data indicative of a position of a first coupler of a first vehicle system and positioning data indicative of a position of a second coupler of a second vehicle system during a coupling event of the vehicle systems. A controller includes one or more processors that receive the positioning data of the first and second couplers and determines whether the first coupler is misaligned with the second coupler. The controller may initiate an action of the first coupler, the second coupler, the first vehicle system, or the second vehicle system to change a position of the first coupler, the second coupler, the first vehicle system, or the second vehicle system. Changing the position of the first coupler, the second coupler, the first vehicle system, or the second vehicle system aligns the first coupler with the second coupler.

  • Patent number: 12139377
    Abstract: A control unit performs a travel stop process for stopping travel of a travel unit in response to an indicator detection unit detecting a stop notice indicator section and then detecting a stop position indicator section. After the travel of the travel unit is stopped as a result of the travel stop process, the control unit performs a transfer process for causing a transfer unit to transfer an article. The control unit performs, instead of the transfer process, anomaly notification processing for providing a notification of an occurrence of an anomaly to a superordinate control unit, after the travel of the travel unit is stopped by the travel stop process, in response to: (i) a travel distance, from a position at which the indicator detection unit has detected the stop notice indicator section, being smaller than a determination distance smaller than a notice distance, and (ii) the indicator detection unit detecting the stop position indicator section.
