Abstract: A refrigeration arrangement for traction vehicles includes a first closed circuit configured as a compression refrigeration machine containing a refrigerant as a first carrier medium, evaporator and condenser. The evaporator absorbs heat into the first circuit. The condenser transfers heat from the first circuit. The first circuit is coupled, via the evaporator, to a closed second circuit containing a liquid second carrier medium for heat transport. The second circuit, for cooling, takes heat and transfers it to the second carrier medium. The heat is conveyed, by the second carrier medium, to the evaporator for transfer to the first circuit. The first circuit is coupled, via the condenser, to a closed third circuit containing a liquid third carrier medium for heat transport. The third circuit causes heat from the first circuit, transferred into the third circuit by the condenser, to be transferred to surroundings with heat from traction systems.

Abstract: Various embodiments of the teachings herein include an insulation system. An example includes a polymer blend in the form of a solid two-dimensional insulation material, a material for wire insulation by means of extrusion and/or an injection-molded and/or compression-molded article. The blend is resistant to partial discharges and at least partly replaces any mica content in the insulation system. The blend comprises at least three blend partners including at least one copolymer based on polyetherimide and siloxane blended with at least two high-temperature thermoplastics. At least of one the high-temperature thermoplastics is in semicrystalline form, such that spherulites are detectable in the polymer blend.

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: An absorption circuit arrangement is for a traction converter of a rail vehicle. The traction converter has a first power converter, a second power converter, a DC link circuit connecting the first power converter and the second power converter with a first and a second voltage potential and a link circuit capacitance arranged in the DC link circuit. The absorption circuit arrangement is arranged in the DC link circuit and is connected in parallel with the link circuit capacitance and contains a switching arrangement having a switching unit and an inductance. Each switching unit contains two terminals, two controllable power semiconductor switches and a switching unit capacitance and is configured, dependent upon switching settings of the power semiconductor switches, to provide at least two different voltages at the terminals.

Abstract: A method for predicting an occupancy state of a passenger seat and for traffic management of passengers, includes determining an actual occupancy state of the passenger seat by using sensors, acquiring information associated with the future occupancy state of the passenger seat, determining prediction data relating to a future occupancy state of the passenger seat on the basis of the actual occupancy state and the associated information by using a data processing apparatus, and outputting the prediction data to passengers by using an output apparatus. A route guidance for passengers is determined on the basis of the prediction data, and the route guidance is output to passengers by using an output apparatus. A system for carrying out the method is also provided.

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 vehicle, particularly a rail vehicle, includes at least one brake resistor assembly having electrical brake resistors which can receive electrical braking energy and convert the electrical braking energy into waste heat during braking operation of the vehicle. The brake resistors are divided into a first subgroup and a second subgroup, the first sub-group and the second sub-group are electrically connected in parallel, and an evaluating device monitors functional capability of the brake resistors on the basis of a measured variable indicating a differential current between a first subgroup current flowing through the first subgroup and a second subgroup current flowing through the second subgroup. A method for monitoring electrical braking resistors of a vehicle is also provided.

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 method for dewatering an operating substance, more particularly a fuel, preferably during the operation of a vehicle, more particularly a rail vehicle, includes conveying an operating substance from an operating substance tank. Water present on or in the fuel is first collected in a water container, and water is conveyed, in chronological order, from the water container back to the operating substance tank, then to an exhaust system and/or from the operating substance tank to the exhaust gas system. A dewatering device for an operating substance, more particularly a fuel for a vehicle, more particularly a rail vehicle, includes a water container, in which water present on or in the fuel is collected. The dewatering device has a dewatering conduit or line which runs from the water container to an operating-substance tank of the vehicle and/or to an exhaust-gas system of the vehicle.
