Patent number: 11479283Abstract: A method operates a track-bound traffic system which carries out a determination that a first track section part lying between a track-bound vehicle and a second track section is free of vehicles. A track-side device disposed in a first track section at a distance to an adjacent second track section, transmits status information which characterizes the second track section as being free of track-bound vehicles, and the transmitted status information is received by a vehicle traversing the first track section. The distance is measured such that no other track-bound vehicle fits in a first track section part lying between the track-bound vehicle and the second track section when the track-bound vehicle receives the status information, and the first track section part lying between the track-bound vehicle and the second track section is identified as being free of other track-bound vehicles by the track-bound vehicle based on the received status information.Type: GrantFiled: May 14, 2018Date of Patent: October 25, 2022Assignee: Siemens Mobility GmbHInventors: Peter Luehrs, Karsten Rahn, Oscar Alonso Garrido

Patent number: 11479282Abstract: A method operates a track-bound traffic system which in a particularly efficient manner and at the same time with a comparably low degree of complexity allows the position of at least one vehicle end of a track-bound vehicle to be ascertained. For this purpose, the method is carried out such that a track-side device transmits first information which directly or indirectly characterizes the location of the track-side device and second information which directly or indirectly characterizes the travel direction of a track-bound vehicle. The first and second information is received by the track-bound vehicle at the location of the track-side device; and a position of at least one vehicle end of the track-bound vehicle is ascertained by the track-bound vehicle on the basis of the received first and second information.Type: GrantFiled: May 14, 2018Date of Patent: October 25, 2022Assignee: Siemens Mobility GmbHInventors: Oscar Alonso Garrido, Peter Luehrs, Karsten Rahn

Patent number: 10906572Abstract: A method for the detection of a crosstalk phenomenon in the communication between a wayside transmission unit, especially a balise, and an on-board unit including an antenna unit, of a railway vehicle, includes the steps of receiving an excitation signal of the wayside transmission unit by using the antenna unit in a moving state of the railway vehicle and measuring an electric and/or a magnetic field in a near field of the wayside transmission unit by using the antenna unit upon reception of the excitation signal. A near field to far field transformation on the field measured in the measuring step is performed to detect a presence of a crosstalk phenomenon. A corresponding an on-board unit is also provided.Type: GrantFiled: November 20, 2017Date of Patent: February 2, 2021Assignee: Siemens Mobility GmbHInventors: Bhabani Nayak, Karsten Rahn

Patent number: 10752270Abstract: A method and device for ascertaining movement authority for track-bound vehicles allow interference with a driving operation resulting in special operational situations or disturbances to be kept as low as possible. The position of the vehicle is determined and used to check whether the vehicle is located completely in an axle-counting section of an axle-counting system. The number of axles of the vehicle is compared with the number of axles located in the relevant section according to the system. If the vehicle is located completely in the relevant section and the number of axles of the vehicle matches the number of axles located in the section according to the system, a movement authority is ascertained for the vehicle. The part of the relevant section in front of the vehicle in the driving direction is assumed to be free of other vehicles when ascertaining the movement authority.Type: GrantFiled: May 12, 2016Date of Patent: August 25, 2020Assignee: Siemens Mobility GmbHInventors: Andreas Driemel, Jan Norden, Karsten Rahn, Patrik Zuralski

Patent number: 10737708Abstract: A method for operating vehicles, in particular track-bound vehicles, permits two vehicles to approach one another even to comparatively short distances and at the same time can be implemented with comparatively low expenditure. For this purpose, a collision by a first vehicle towards the rear of a second vehicle is detected by the second vehicle, a warning message is emitted by the second vehicle triggered by the detection of the collision or running into from the rear, and a braking process is triggered by the first vehicle on the basis of the warning message emitted by the second vehicle. A device for a vehicle which detects the collision of a further vehicle is also provided.Type: GrantFiled: March 24, 2016Date of Patent: August 11, 2020Assignee: Siemens Mobility GmbHInventors: Lothar Becke, Karsten Rahn, Luis Riera Sanchez, Frauke Schossig, Rene Wettig

Patent number: 10457300Abstract: In a normal operating mode, track-bound vehicles report their respective position to a track-side device and the track-side device determines a respective movement authority taking into account the reported positions for the track-bound vehicles and transmits the movement authorities to the respective track-bound vehicle. If a track-bound vehicles is faulty and cannot ensure its integrity, and it is consequently not able to report a valid or reliable position, a switch-over into a fault mode takes place without interrupting the travel operation of the track-bound vehicles. In the fault mode the faulty track-bound vehicle determines a position of one of its vehicle ends and reports the position together with information that it cannot ensure its integrity, to the track-side device. Movement authorities are then determined by the track-side device, taking into account the reported position of the one vehicle end and track vacancy information of a track-side track vacancy system.Type: GrantFiled: February 26, 2016Date of Patent: October 29, 2019Assignee: Siemens Mobility GmbHInventor: Karsten Rahn

Patent number: 9580092Abstract: A method for operating a rail vehicle in a railway system includes providing at least one optical waveguide which is laid next to at least one railway track and into which light pulses are fed, using the optical waveguide as a distributed acoustic sensor, and detecting backscattered light. In order to configure such a method in such a way that it meets stringent safety requirements relatively easily, a rail vehicle is used having a sound generator which can be adjusted in terms of its frequency spectrum in such a way that it indicates an emergency. When the sound generator is activated, an emergency signal of the rail vehicle is acquired if a frequency spectrum which corresponds to the adjusted emergency frequency spectrum of the sound generator is detected in the backscattered light. A railway system is also provided.Type: GrantFiled: September 10, 2013Date of Patent: February 28, 2017Assignee: Siemens AktiengesellschaftInventors: Gamze Arpaci, Wolfgang Bachmann, Doris Martitz, Karsten Rahn

Patent number: 9254854Abstract: A method and a device for determining a train length of a plurality of coupled railroad traction vehicles, each having a vehicle device with an ID specific to the railroad traction vehicle, include determining the train length of arbitrarily long train sets in a secure and simple signaling manner by having vehicle devices determine if the railroad traction vehicle is coupled on one side or both sides by evaluating coupling contacts. The IDs of all of the coupled railroad traction vehicles or ID pairs indicating adjoining relationships of railroad traction vehicles directly coupled to one another are successively transmitted to a particular vehicle device by digital I/O connections between the vehicle devices. The device determines the train length as a function of received IDs or ID pairs.Type: GrantFiled: March 31, 2011Date of Patent: February 9, 2016Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Christian Bode, Karsten Rahn
