Obstacle detection enhancement data are transmitted from a server to at least one moving conveyance embedding an obstacle detection system and an on-board wireless radio unit communicating with the server via wireless link. To do so, downlink transmission resources are allocated to each on-board wireless radio unit in a transmission cycle C.sub.n, by optimizing the difference between a distance travelled by the moving conveyance during a transmission cycle and a distance covered by the obstacle detection enhancement data made available to the obstacle detection system at a next transmission cycle C.sub.n+1, wherein the volume of obstacle detection enhancement data expected to be transmitted during the transmission cycle C.sub.n is determined from volume-to-distance ratio information b.sub.k stored in a database and from actual quality of the wireless link.

A method of bank to bank trimming for a locomotive engine during steady state operation comprises receiving a plurality of operating parameter signals, receiving a fuel quantity signal for each of a standard cylinder bank and a donor cylinder bank, providing a trim map, determining whether the engine is operating in a steady state condition based on the plurality of operating parameter signals, determining a target fuel injection duration for each of the standard cylinder bank and the donor cylinder bank if the engine is operating in a steady state condition, and adjusting an actual fuel injection duration to equal the target fuel injection duration for the standard cylinder bank and the donor cylinder bank.

A parking verification system and method, a movement verification system and method, and a monitoring system and method for a train, or other transit vehicle.

A monitoring and measuring device for an air supply system of a vehicle, in particular a rail vehicle, includes a compressor which is designed to provide compressed air; a defined volume which is situated downstream of the compressor; a shut-off valve which is situated downstream of the defined volume; a pressure sensor which is provided at any desired position on the pressure line between the compressor and the shut-off valve and is configured to measure the pressure that builds in the defined volume. A first or second air drying device, for example, is used as the defined volume. The pressure curve measured by the pressure sensor can indicate whether there is a fault or a leak. A method for monitoring and for measuring parameters of an air supply system of a vehicle, in particular a rail vehicle is also provided.

Included are: a unit that receives an indicated read range for an identification tag being affixed to one of devices installed in a train and storing an individual information item identifying the device; a unit that obtains a design information item indicating a model number of a device within the indicated read range and an installation position of the device with the model number in vehicles of the train; a unit that obtains a model number information item indicating a relationship between the model number and the individual information item; a reader that reads an individual information item of the device stored in an identification tag; and a unit that ascertains a model number of the device having the individual information item read and associates the installation position with the individual information item of the device having the model number when the device ascertained is present in the read range.

Systems and methods for correlating wireless communication performance with vehicle system configurations determine wireless message characteristics of wireless messages communicated between vehicles in vehicle systems and locations along a route where the wireless message characteristics were determined. The wireless message characteristics and the locations can be determined during movement of the vehicle systems along a route. Relative positions of the vehicles in the vehicle systems is obtained, and a signal propagation profile is determined based on the wireless message characteristics, the locations where the wireless message characteristics were determined, and the relative positions of the vehicles. The signal propagation profile can represent relationships between the wireless message characteristics, the relative positions of the vehicles, and the locations along the route. This profile can be used to control movement and/or communication of other rail vehicle systems, to generate trip plans for other vehicle systems, to diagnose communication faults, and the like.

The invention relates to a sound diffusion system embedded in a railway vehicle and comprising: a plurality of groups of speakers distributed in the cars, each group of speakers being located in a respective diffusion zone of the railway vehicle; a control device of the speakers configured to broadcast generic sound signals via the different groups of speakers; and at least one reception device, each reception device being associated with a single group of speakers and being able to receive a control signal from a control device outside the railway vehicle, the control device being configured, upon reception of a control signal by one of the reception devices, to broadcast a specific sound signal solely via the associated group of speakers.

The invention relates to automatically determining an efficient topology of sensor network preferably installed in an infrastructure, such as railway infrastructure. The invention discloses a system, a method, a user device. The invention further provides a processing component configured to receive sensor data from at least one or a plurality of sensor node(s). Further, the invention provides a trajectory module, configured to generate at least a part of trajectory data based on sensor data.

The invention relates to an apparatus for configuring systems, the apparatus being positioned as intended in a rail vehicle and comprising—a data-processing unit—information-transmitting connections between the data-processing unit and the systems—a selection unit for selecting a saved profile—an input unit for inputting operating parameters—a receiving unit for receiving additional or altered profiles.

A system and method for simulating positive train control (PTC) systems in a local and controlled environment using software and hardware. The system can simulate various functionalities of the PTC system in the environment using software and hardware components. The system can instruct the software of a train management computer (TMC) to control electromechanical valves to simulate air compression on brake pipes in response to the PTC system executing a penalty on the locomotive. The system can display statuses of various systems on the locomotive to a user using a cab display unit (CDU). The system can control the software and hardware components to simulate warnings and actions from the PTC system allowing locomotive engineers and conductors to experience the PTC system for optimum training.
