  • Patent number: 12099336
    Abstract: A method for state-based maintenance of an access device of a vehicle, in particular of a public transport vehicle, wherein the access device includes a moveable element and an electric drive for moving the moveable element and is attached to the vehicle. The drive is controlled with control signals, wherein actual state signals for describing the state are generated based on a detected state of the access device. The control signals are applied to a physical simulation model for computationally simulating the access device and determining expected target state signals and wherein based on a comparison between the actual state signals and associated target state signals, a maintenance state of the access device is determined. The simulation model is adjusted based on the comparison between the actual state signals and the associated target state signals.

  • Patent number: 12079008
    Abstract: Autonomous vehicles may be dynamically directed to rendezvous with autonomous vehicle trains or convoys. Current location and/or route information of the Autonomous Vehicle Train (AVT) may be received by an autonomous vehicle. The autonomous vehicle may compare its current location and/or route information to determine a rendezvous point with the AVT. The autonomous vehicle may route itself to the rendezvous point with the AVT. Once there, the autonomous vehicle may verify the identification of the AVT, such as by using sensors/cameras to verifying a lead vehicle of the AVT (e.g., by verifying make/model, color, and/or license plate). The autonomous vehicle and lead vehicle may communicate to allow the autonomous vehicle to join the AVT. A minimum level of autonomous vehicle functionality may be verified prior to the autonomous vehicle being allowed to join the AVT. As a result, vehicle traffic flow and travel experience by passengers may be enhanced.

  • Patent number: 12046825
    Abstract: An antenna arrangement for the mobile communication of a rail vehicle and a rail vehicle with an antenna arrangement of the type. The antenna arrangement has at least two transmitting antennas and at least two receiving antennas. The transmitting antennas are spatially grouped in a transmitting group and the receiving antennas are spatially grouped in a receiving group. The distances between the transmitting antennas and between the receiving antennas is smaller than the overall distance between the transmitting group and the receiving group. The antennas can thereby be arranged in a much more space-saving fashion on the vehicles because large distances have to be provided only between the groups, not between the antennas within the groups. Where the space needed is low, interference-free operation of the antennas is thus advantageously possible.

    Abstract: A method of installing/verifying positive train control components begins by entering component details into a data entry screen (e.g., a component type; serial number; name of the installer; train line name; a location description). A rough installation location is determined, and the component is installed. A GPS receiver determines the exact location of the installed component, which is entered with the component details. Photographs of the installed component are attached thereto. An installation icon for the installed component is overlaid on a digital map at the determined GPS location. Toggling the installation icon causes displaying of the data. An inspector physically verifies the entered details and GPS location of the installed component using a verification screen, and a third-party GPS receiver. When the two GPS obtained positions are within a threshold amount, and the details are correct, the inspector toggles a radio button confirming the data, which is otherwise corrected.

  • Patent number: 11981362
    Abstract: A method for determining an actual geometry of a track by a track inspection vehicle which is movable on the track, wherein reference points positioned in a lateral environment of the track are automatically recorded by a non-contacting recording system arranged on the track inspection vehicle and their respective actual distance from the track is determined. A three-dimensional trajectory of the track is recorded by an inertial measuring system arranged on the track inspection vehicle, wherein the trajectory is divided by a computing unit into trajectory sections each having a section starting point related to a first reference point and a section end point related to a second reference point, wherein a virtual longitudinal chord is defined for each trajectory section in relation to the assigned reference points, and wherein actual distances between the trajectory and the respectively defined longitudinal chord are calculated for each trajectory section.

  • Patent number: 11958515
    Abstract: A method for identifying properties of rail-guided vehicles uses an axle counter to detect vehicle measurement data as the vehicle crosses. The measurement data are analyzed in a computer and speed and distances between vehicle axles are ascertained. A property of the vehicle is ascertained in a computer based on the ascertained speed and distances between axles. A checking step ascertains a pattern of normal distances between axles in that a normal distance between axles calculated by considering a predefined normal speed is assigned to each ascertained distance between axles, and by considering their order, the normal distances between axles merge to form the pattern. The pattern is compared with reference patterns, and upon identified conformity of the pattern and reference pattern, a type linked to the reference pattern is assigned to the vehicle as a property. An apparatus and computer program determining properties of vehicles are also provided.
