10229036 · 2019-03-12 · ·

A method operates a safety-critical system, which system contains at least one first data device having approved, safety-relevant software and at least one reference data device having the same approved, safety-relevant software. In the method, after a type check of the system, the at least one first data device is equipped with at least one piece of non-safety-relevant additional software and the at least one reference data device is blocked from software modifications. Before safety-related data information is output, output information of the at least one first data device and of the at least one reference data device are checked for a match with regard to the safety-relevant software by a comparison device, and the safety-related data information is output in the case of a match.

Method and system for timetable optimization utilizing energy consumption factors

Systems and methods for synchronizing two or more vehicles operating on an electric transportation line to optimize energy consumption. A controller is provided having a computer memory component storing a set of computer-executable instructions, a list of braking intervals, and a list of acceleration intervals for the vehicles. The controller also has a processing component configured to execute the set of computer-executable instructions to operate on the list of braking intervals and the list of acceleration intervals to minimize an energy consumption of the electric transportation line over a determined period of time by shifting acceleration intervals to synchronize with braking intervals. A dedicated heuristic greedy algorithm and an energy model are implemented in the controller as part of the computer-executable instructions to achieve the improved energy consumption.

Automated system for determining optimal train driving system parameters

A system for optimizing the control of a train that includes an interface for receiving data representing a set of operational parameters for a train that will traverse a predetermined route. A server is interconnected to the interface and programmed to generate a plurality of scenarios using the same set of operational parameters but different control parameters. A simulator is programmed to perform a simulation of the operation of the train as described by the operation parameters and control parameters. The server is programmed to review the results of the simulation and score how closely the simulations achieved one or more performance metrics, thereby identifying which control parameters should be used by the train and allowing the control parameters to be transmitted to the train.

Provided is a course correction procedure generation device that comprises: a measurement data acquisition unit for acquiring measurement data on a course; a simulation execution unit with which a travel simulation for simulating travel by the vehicle on the course is executed on the basis of the measurement data and a speed that is established in accordance with the location of the vehicle on the course; and a correction procedure generation unit for generating a correction procedure on the basis of the result of the travel simulation, the correction procedure being information indicative of content for correcting the course.

VEHICLE CONTROL SYSTEM AND METHOD

A control system and method includes obtaining information associated with a vehicle system that includes one or more vehicles that are configured to move along a route. The vehicle system information is applied to a trip simulation to determine how the vehicle system is expected operate while the vehicle system moves along the route. The trip simulation includes one or more anticipated operating conditions of the vehicle system and/or anticipated route conditions the vehicle system is expected to be exposed to as the vehicle system moves along the route. It is determined whether the vehicle system will be able to stop at one or more locations along the route based on the application of the vehicle system information to the trip simulation. An alert is communicated responsive to determining that the vehicle system will be unable to stop at the one or more locations along the route.
