Abstract

A system includes one or more processors configured to communicatively link a remote-control system disposed off-board a vehicle system with an onboard vehicle control system on the vehicle system. The remote-control system and the onboard vehicle control system are configured to control movement of the vehicle system, wherein the one or more processors are configured to transfer control of the movement of the vehicle system from the remote-control system to the onboard vehicle control system based on one or more of a location, a condition of the vehicle system, or by one or more of a request or condition of an operator or from the onboard vehicle control system to the remote-control system based on the one or more of the location, the condition of the vehicle system, or by the one or more of the request or condition of the operator.

Claims

1. A system comprising:

one or more processors configured to communicatively link a remote-control system disposed off-board a rail vehicle system with an onboard vehicle control system on the rail vehicle system, the remote-control system and the onboard vehicle control system configured to control movement of the rail vehicle system;

wherein the one or more processors are configured to transfer control of the movement of the rail vehicle system from the remote-control system to the onboard vehicle control system based on one or more of a location, a condition of the rail vehicle system, or by one or more of a request or condition of an operator, or from the onboard vehicle control system to the remote-control system based on the one or more of the location, the condition of the rail vehicle system, or by the one or more of the request or condition of the operator, wherein control of the movement of the rail vehicle system includes controlling one or more of a throttle setting or a brake setting of the rail vehicle system.

2. The system of claim 1, wherein the one or more processors are configured to generate and provide a notification signal to an output device onboard the rail vehicle system that automatically informs the operator onboard or near the rail vehicle system of transfer of control of the movement of the rail vehicle system from the remote-control system to the onboard vehicle control system or from the onboard vehicle control system to the remote-control system.

3. The system of claim 1, wherein the one or more processors are configured to transfer control of the movement of the rail vehicle system from the remote-control system to the onboard vehicle control system or to transfer control of the movement of the rail vehicle system to the remote-control system from the onboard vehicle control system responsive to the rail vehicle system entering the location being a designated geographic area or a designated segment of a track.

4. The system of claim 1, wherein the location is a designated practice area for manual control of the rail vehicle system by the operator.

5. The system of claim 1, wherein the condition is a fault state of the rail vehicle system.

6. The system of claim 1, wherein the condition is a communication loss between the rail vehicle system and the remote-control system.

7. The system of claim 1, wherein the condition is a decreased alertness of the operator.

8. The system of claim 1, wherein the onboard vehicle control system configured to one or more of automatically control the movement of the rail vehicle system without operator intervention or automatically present instructions to the operator that instruct the operator how to control the movement of the rail vehicle system.

9. The system of claim 1, wherein the one or more processors are configured to lock out operator control of the movement of the rail vehicle system, receive an instruction from the remote-control system to test an operation of the rail vehicle system, and communicate visual data representative of an area outside of the rail vehicle system to the remote-control system prior to or during transfer of control of the movement of the rail vehicle system from the onboard vehicle control system to the remote-control system.

10. The system of claim 1, wherein the one or more processors are configured to automatically stop the rail vehicle system, activate the onboard vehicle control system, and disconnect communication with the remote-control system prior to or during transfer of control of the movement of the rail vehicle system from the remote-control system to the onboard vehicle control system.

11. A method comprising:

communicatively linking a remote-control system disposed off-board a rail vehicle system and an onboard vehicle control system on the rail vehicle system with one or more processors, the remote-control system and the onboard vehicle control system configured to control movement of the rail vehicle system, wherein control of the movement of the rail vehicle system includes controlling one or more of a throttle setting or a brake setting of the rail vehicle system, and

transferring control of the movement of the rail vehicle system from the remote-control system to the onboard vehicle control system based on one or more of a location, a condition of the rail vehicle system, or one or more of a request or condition of an operator or from the onboard vehicle control system to the remote-control system based on the one or more of the location, the condition of the rail vehicle system, or the one or more of the request or condition of the operator with the one or more processors.

12. The method of claim 11, wherein the one or more processors transfer control of the movement of the rail vehicle system from the remote-control system to the onboard vehicle control system or transfer control of the movement of the rail vehicle system to the remote-control system from the onboard vehicle control system responsive to the rail vehicle system entering the location being a designated geographic area of a designated segment of a track.

13. The method of claim 11, wherein the location is a designated practice area for manual control of the rail vehicle system by the operator.

14. The method of claim 11, wherein the condition is a fault state of the rail vehicle system.

15. The method of claim 11, wherein the condition is a communication loss between the rail vehicle system and the remote-control system.

16. The method of claim 11, wherein the condition is a decreased alertness of the operator.

17. The method of claim 11, further comprising the onboard vehicle control system one or more of automatically controlling the movement of the rail vehicle system without operator intervention or automatically presenting instructions to the operator that instruct the operator how to control the movement of the rail vehicle system.

18. The method of claim 11, further comprising locking out operator control of the movement of the rail vehicle system, receiving an instruction from the remote-control system to test an operation of the rail vehicle system, and communicating visual data representative of an area outside of the rail vehicle system to the remote-control system prior to or during transferring of control of the movement of the rail vehicle system from the onboard vehicle control system to the remote-control system.

19. The method of claim 11, further comprising automatically stopping the rail vehicle system, activating the onboard vehicle control system, and disconnecting communication with the remote-control system prior to or during transferring of control of the movement of the rail vehicle system from the remote-control system to the onboard vehicle control system.

20. A system comprising:

one or more processors configured to communicatively link with a rail vehicle system for remotely controlling movement of the rail vehicle system, the rail vehicle system also including an onboard vehicle control system for locally controlling movement of the rail vehicle system,

wherein the one or more processors are configured to transfer control of the movement of the rail vehicle system from a remote-control system to the onboard vehicle control system based on one or more of a location, a condition of the rail vehicle system, or one or more of a request or condition of an operator or from the onboard vehicle control system to the remote-control system based on the one or more of the location, the condition of the rail vehicle system, or the one or more of the request or condition of the operator, wherein control of the movement of the rail vehicle system includes controlling one or more of a throttle setting or brake setting of the rail vehicle system.
