Abstract:
A system includes an energy management system disposed onboard a vehicle system configured to travel on a route during a trip. The energy management system is configured to receive trip information that includes one or more constraints including at least one of speed, distance, or time restrictions for the vehicle system along the route. The energy management system is further configured to generate a trip plan for controlling movement of the vehicle system along the route during the trip. The trip plan is generated based on the one or more constraints. The trip plan has a plan speed profile that designates speeds for the vehicle system according to at least one of distance or time during the trip. The energy management system is further configured to control movement of the vehicle system during the trip according to the plan speed profile of the trip plan.
Abstract:
A control system identifies vehicle systems for combining into a larger convoy. Each the vehicle systems is formed from at least one propulsion-generating vehicle and at least one non-propulsion-generating vehicle. The control system directs the identified vehicle systems to couple with each other for travel as the convoy from a first location toward a different, second location. The control system directs a first vehicle system in the convoy to separate from the convoy and/or a second vehicle system to join the convoy by coupling with at least one of the vehicle systems in the convoy in an intermediate location between the first and second locations. The vehicles in each of the vehicle systems in the convoy remain connected during separation of the first vehicle system from the convoy and/or during joining of the second vehicle system to the convoy.
Abstract:
A location determination system includes one or more processors configured to determine a location of a vehicle system based on output from a location determination system onboard the vehicle system. The one or more processors also are configured to determine whether the location of the vehicle system as determined by the location determination system is accurate based on one or more of performance of the vehicle system, communication between two or more vehicles in the vehicle system, one or more other locations determined by one or more other location determination systems onboard the vehicle system, and/or operation of a brake system of the vehicle system.
Abstract:
A method includes identifying power outputs to be provided by propulsion-generating vehicles of a vehicle system for different locations along a route and calculating handling parameters of the vehicle system at the locations along the route. The handling parameters are representative of at least one of coupler forces, coupler energies, relative vehicle velocities, or natural forces exerted on the vehicle system. The method also includes determining asynchronous operational settings for the propulsion-generating vehicles at the locations. The asynchronous operational settings represent different operational settings that cause the propulsion-generating vehicles to provide at least the power outputs at the locations while changing the handling parameters of the vehicle system to designated values at the locations. The method further includes communicating the asynchronous operational settings to the propulsion-generating vehicles in order to cause the propulsion-generating vehicles to implement the asynchronous operational settings at the different locations.
