System and method for controlling a vehicle system
A system (e.g., a control system) includes a sensor configured to monitor an operating condition of a vehicle system during movement of the vehicle system along a route. The system also includes a controller configured to designate one or more operational settings for the vehicle system as a function of time and/or distance along the route.
1. A system comprising:
at least a first sensor configured to monitor at least one operating condition of a vehicle system while traveling a route from a first location to at least a second location;
a control system, the control system including at least one or more processors, the control system configured to receive data communicated from the at least first sensor and to generate a trip plan that includes plural designated operational settings for control of the vehicle system during a trip;
wherein the operational settings include at least a first operational mode and second operational mode, wherein the second operational mode includes stopping the vehicle system such that multiple vehicles of the vehicle system are bunched together with one or more couplers disposed between the vehicles of the vehicle system in a slack state once the vehicle system is stopped;
wherein the control system is configured to control the vehicle system in the first operational mode responsive to the operating condition of the vehicle system being at least one of at or above a designated threshold; and
wherein the control system is configured to control the vehicle system in the second operational mode responsive to the operating condition of the vehicle system being below the designated threshold.
2. The system of claim 1 , wherein the at least one operating condition of the vehicle system is a speed of the vehicle system along the route, and the designated threshold is a threshold speed.
3. The system of claim 2 , wherein the sensor is a speed sensor configured to determine the speed of the vehicle system along the route, the speed sensor configured to communicate the speed of the vehicle system to the control system, the control system configured to compare the speed of the vehicle system to the threshold speed.
4. The system of claim 1 , wherein the at least one operating condition of the vehicle system is a proximity of the vehicle system to a designated location along the route for the trip, and the designated threshold is a threshold proximity.
5. The system of claim 4 , wherein the sensor is a locator device configured to determine a location of the vehicle system along the route, the locator device being configured to communicate the location of the vehicle system to the control system, the control system configured to determine the proximity of the vehicle system to the designated location and compare the proximity to the threshold proximity.
6. The system of claim 1 , wherein the control system is configured to designate one or more of speed, throttle settings, brake settings, or accelerations for the vehicle system as the operational settings.
7. The system of claim 1 , wherein the control system is further configured to communicate a control signal to at least one of a propulsion subsystem, a braking subsystem, or a user interface device of the vehicle system, the control signal including at least some of the operational settings designated by the controller.
8. The system of claim 1 , wherein the first operational mode includes controlling a speed of vehicle system to be above a threshold speed.
9. The system of claim 1 , wherein the second operational mode includes stopping the vehicle system within a designated threshold distance of a designated stopping location.
10. The system of claim 1 , wherein the second operational mode includes stopping the vehicle system such that each of the vehicles comes to a stop after a preceding vehicle of the vehicles in the vehicle system.
11. The system of claim 1 , wherein the second operational mode includes stopping the vehicle system such that one or more wheels of the vehicle system retain adhesion with the route.
12. The system of claim 1 , wherein the second operational mode includes controlling a distance between the vehicles of the vehicle system.
13. The system of claim 1 , wherein the second operational mode includes controlling a tension between the vehicles of the vehicle system.
14. The system of claim 1 , wherein the first operational mode includes the operational settings that drive the vehicle system during the trip toward achievement of a first objective during movement of the vehicle system along the route based on the trip plan.
15. The system of claim 1 , wherein the second operational mode includes the operational settings that drive the vehicle system during the trip toward achievement of a second objective during movement of the vehicle system along the route based on the trip plan.
16. A method comprising:
monitoring, with at least one sensor, at least one operating condition of a vehicle system as the vehicle system travels along a route;
communicating data from the sensor to a control system, the control system comprising a processor to determine if the at least one operating condition is above or below a designated threshold and the control system is configured to designate one or more operational settings for the vehicle system;
generating a trip plan for the vehicle system that designates operating settings for at least a first operational mode and designates operating settings for at least a second operational mode, the second operational mode including stopping the vehicle system such that multiple vehicles of the vehicle system are bunched together with one or more couplers disposed between the vehicles of the vehicle system in a slack state once the vehicle system is stopped according to the trip plan; and
controlling movement of the vehicle system as the vehicle system travels along the route according to the operating settings designated by the trip plan.
17. The method of claim 16 , wherein generating the trip plan includes designating one or more of speeds, throttle settings, brake settings, or accelerations as the operating settings of the trip plan.
18. The method of claim 16 , wherein the first operational mode includes reducing fuel consumption by the vehicle system.
19. The method of claim 16 , wherein the first operational mode includes reducing emissions generated by the vehicle system.
20. The method of claim 16 , wherein the first operational mode includes a change in handling of the vehicle system.
21. The method of claim 16 , wherein the first operational mode includes a reduction in travel time relative to the vehicle system traveling along the route for the trip according to operational settings that differ from the one or more operational settings of the trip plan.
