Abstract: The wireless relay device according to the present disclosure includes: a reception unit to receive train control information; an information classification unit to classify the train control information into first control information requiring immediacy and second control information not requiring immediacy; a message generation unit to generate one message from the first control information contained in a piece of the train control information and to generate one message from a plurality of pieces of the second control information contained in a plurality of pieces of the train control information; and a transmission unit to transmit the messages generated by the message generation unit. With this configuration, it is possible to reduce the number of the data transfer messages which does not require immediacy while the instantaneous communication for the control information which requires immediacy is maintained.

Abstract: A vehicle, in particular to a rail vehicle, has at least one drive motor and a brake control device. A monitoring device measures, in the braking mode of the vehicle, at least one drive current which flows through the drive motor, and at least one drive voltage which is applied to the drive motor, to form measured values, and to generate operational information which specifies the mode of operation of the drive motor, in particular braking information which specifies a braking effect of the drive motor, on the basis of the measured values.

Abstract: A system and method generate a trip plan for a trip of a vehicle system along a route. The usage of an engine during the trip is determined based on engine operational parameters, energy storage device operational parameters, and one or more objectives of the trip desired to be achieved. The usage of the energy storage device during the trip is also determined based on the engine operational parameters, the energy storage device operational parameters, and the one or more objective, including when to charge or discharge the energy storage device during the trip.

Abstract: A data extraction apparatus includes a parameter analysis unit that performs analysis of learning text information, extracts words that serve as machine learning parameters, and classifies the words into types of parameters; a grouping settings display unit that finalizes search-target data and clustering conditions based on the parameters; at least one clustering training data extraction unit that extracts training data from a database based on the search-target data and the clustering conditions; at least one clustering unit that performs clustering based on the clustering condition on the training data; an applicable-clustering determination unit that performs analysis of search text information and identifies search-target data serving as a narrowing-down condition and which clustering unit is to be operated; and a search range specification unit that causes the clustering unit to operate and extracts a narrowed range of search-target data from the database based on an operation result.

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.

Abstract: A method for measuring a parameter relevant to a journey of a rail vehicle. A parameter measurement value is determined using a control loop. A vehicle-side torque acting on a rotational part on the vehicle side is ascertained. A calculation module uses the vehicle-side torque value and a frictional engagement torque acting between the rotational part and a rail, to calculate a rotational acceleration of the rotational part and an expected rotational speed. A difference between the rotational estimated value and an actual rotational speed is supplied to a control device which outputs a controller output value at the output side. A frictional engagement torque value is recalculated with the controller output value and is coupled back into the computer module to close the control loop. The controller output and/or the recalculated frictional engagement torque value is considered the parameter measurement value, which is stored or output.

Abstract: A method identifies and verifies control software of a rail vehicle. In the method, the control software is formed by functions, with each function fulfilling an associated task. As a networked collective, the functions form the structure of the control program. A function-dependent checksum is generated for each function. A structure-dependent checksum is generated for the structure. A total checksum is generated for the control software from the function-dependent checksums and the structure-dependent checksum. This total checksum identifies and verifies the control software for homologation in a country.

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.
