Abstract

A power control system for a vehicle system identifies coupler nodes in the vehicle system for travel of the vehicle system along a route. The coupler nodes represent slack states of couplers between vehicles in the vehicle system. The system also determines combined driving parameters at locations along the route where a state of the coupler nodes in the vehicle system will change within the vehicle system during the upcoming movement of the vehicle system. The system determines a restriction on operations of the vehicle system to control the coupler nodes during the upcoming movement of the vehicle system and to distribute the combined driving parameters among two or more of the vehicles.

First claim

What is claimed is:

1. A power control system for a vehicle system, the power control system comprising:
one or more processors configured to identify coupler nodes in a vehicle system for travel of the vehicle system along a route, the coupler nodes representative of slack states of couplers between vehicles in the vehicle system, the one or more processors also configured to determine one or more combined driving parameters at one or more locations along the route where a state of one or more of the coupler nodes in the vehicle system will change within the vehicle system during the upcoming movement of the vehicle system, wherein the one or more processors also are configured to determine a restriction on operations of the vehicle system to control the coupler nodes during the upcoming movement of the vehicle system and to distribute the one or more combined driving parameters among two or more of the vehicles by determining individual driving parameters for the two or more vehicles based on the restriction that is determined.

2. The power control system of claim 1 , wherein the driving parameters that are determined include one or more of a throttle setting of one or more of the vehicles, a brake setting of one or more of the vehicles, a moving speed of one or more of the vehicles, a tractive power generated by one or more of the vehicles, a tractive effort generated by one or more of the vehicles, a braking force generated by one or more of the vehicles, or an acceleration of one or more of the vehicles.

3. The power control system of claim 1 , wherein the couplers include at least one end of car cushioning coupler and the one or more processors are configured to determine the one or more combined driving parameters by determining where the state of the at least one end of car cushioning coupler changes.

4. The power control system of claim 1 , wherein the coupler nodes represent locations in the vehicle system where the vehicles move relative to each other within the vehicle system while the couplers between the vehicles remain in the slack states.

5. The power control system of claim 1 , wherein the combined driving parameters represent synchronous power settings of the vehicles in a first set of the vehicles in the vehicle system and the vehicles in a different, second set of the vehicles in the vehicle system.

6. The power control system of claim 1 , wherein the one or more processors are configured to determine the restriction on the operations of the vehicle system by determining one or more of a lower power limit or an upper power limit on at least one of the vehicles in the vehicle system.

7. The power control system of claim 1 , wherein the one or more processors are configured to generate control signals to control the two or more vehicles according to the individual driving parameters that are determined based on the restriction.

8. A method for controlling a vehicle system, the method comprising:
identifying coupler nodes in a vehicle system for travel of the vehicle system along a route, the coupler nodes representative of slack states of couplers connected to one or more vehicles in the vehicle system;
determining one or more combined driving parameters at one or more locations along the route where a state of one or more of the coupler nodes in the vehicle system will change within the vehicle system during the upcoming movement of the vehicle system; and
determining an individual driving parameter for one or more vehicles based on a restriction that is determined.

9. The method of claim 8 , wherein the driving parameters that are determined include one or more of a throttle setting of one or more of the vehicles, a brake setting of one or more of the vehicles, a moving speed of one or more of the vehicles, a tractive power generated by one or more of the vehicles, a tractive effort generated by one or more of the vehicles, a braking force generated by one or more of the vehicles, or an acceleration of one or more of the vehicles.

10. The method of claim 8 , wherein the coupler nodes represent locations in the vehicle system where the vehicles move relative to each other within the vehicle system while the couplers between the vehicles remain in the slack states.

11. The method of claim 8 , wherein the combined driving parameters represent synchronous power settings of the vehicles in a first set of the vehicles in the vehicle system and the vehicles in a different, second set of the vehicles in the vehicle system.

12. The method of claim 8 , wherein determining the restriction on the operations of the vehicle system includes determining one or more of a lower power limit or an upper power limit on at least one of the vehicles in the vehicle system.

13. A method for controlling a vehicle system, the method comprising:
determining a location along a route during an upcoming trip of a vehicle system that coupler nodes in the vehicle system will collide with each other;
distributing a power output among two or more propulsion-generating vehicles on opposite sides of at least one of the coupler nodes in the vehicle system, the power output preventing the coupler nodes from colliding with each other at the location along the route;
determining a restriction on operations of the vehicle system to control the coupler nodes; and
generating a trip plan for the propulsion-generating vehicles in the vehicle system based on the power output that is distributed and the restriction on operations determined to control the coupler nodes.

14. The method of claim 13 , wherein the coupler nodes represent locations in the vehicle system where segments of one or more vehicles connected by a coupler in the vehicle system move relative to each other within the vehicle system while the coupler remains in a slack state.

15. The method of claim 13 , wherein the power output represents a synchronous power setting for the propulsion-generating vehicles in the vehicle system to generate the power output.

16. The method of claim 15 , wherein distributing the power output includes asynchronously distributing the power output among the propulsion-generating vehicles to cause the propulsion-generating vehicles to generate the total power output.
