摘要： In one embodiment of the subject matter described herein a system is provided. The system includes a location determining circuit configured to acquire position information of a vehicle system moving along a route. The system includes a controller circuit having one or more processors. The controller circuit is configured to calculate curvatures of the route, based at least in part on the position information, to form a curvature waveform. The controller circuit is further configured to generate a route map based on the curvature waveform.

摘要： A system and method for controlling a vehicle system may determine one or more of a route parameter of a route on which the vehicle system is moving or a vehicle parameter of the vehicle system. The system and method may also determine whether a ratio of a lateral force exerted by one or more wheels of the vehicle system on the route to a vertical force exerted by the one or more wheels of the vehicle system on the route increases to a value exceeding a designated threshold as a result of the one or more route parameter of vehicle parameter that is determined. The ratio of the lateral force to the vertical force exerted by the one or more wheels of the vehicle system on the route may be reduced to a value less than the designated threshold by changing an operation of the vehicle system.

摘要： Examples for a traction system are provided. In one example, the traction system includes a nozzle coupled to an air source and configured to be selectively aimed toward a determined portion of a rail surface of a rail, and a conduit configured to supply pressurized air from the air source to the nozzle, the nozzle flexibly coupled thereto. The nozzle is configured for the aim of the nozzle to be controlled to change its aiming direction in response to a change in curvature of the rail, whereby a stream of air from the nozzle impacts the determined portion during movement of the vehicle through the curvature of the rail.

摘要： A control system receives signals representing a presence and position of a secondary movement system onboard a vehicle. The secondary movement system changes movement of the vehicle without generating thrust or propulsion to move the vehicle. The control system creates a schedule of use of the secondary movement system based on the presence and position of the secondary movement system and controls the secondary movement system based on the schedule that is created.
