Abstract

A system includes one or more processors configured to communicatively link a first operator control unit (OCU) disposed off-board a vehicle system with a vehicle control system (VCS) disposed onboard the vehicle system. The vehicle system is formed from first and second vehicles. The VCS is configured to remotely control movement of the second vehicle from the first vehicle, wherein the one or more processors configured to receive a control signal communicated from the first OCU to a communication device that is onboard the first vehicle. The control signal dictates a change in movement operational setting of the second vehicle. The one or more processors configured to direct the communication device to communicate the control signal from the first vehicle to the second vehicle via the VCS, wherein movement of the second vehicle is automatically changed responsive to communicating the control signal from the first vehicle to the second vehicle.

First claim

What is claimed is:

1. A system comprising:
one or more processors configured to communicatively link a first off-board control unit with an onboard communication device disposed onboard a first propulsion-generating vehicle,
wherein the one or more processors also are configured to receive a first signal communicated from the first off-board control unit to the onboard communication device, the first signal dictating a change in a first movement operational setting of the first propulsion-generating vehicle, and
wherein the one or more processors also are configured to receive a second signal communicated from the first off-board control unit to the onboard communication device, the one or more processors configured to send one or more of the second signal or a third signal based on the second signal from the onboard communication device to a second propulsion-generating vehicle that is separate from the first propulsion-generating vehicle,
wherein a second movement operational setting of the second propulsion-generating vehicle is configured to be automatically changed responsive to communicating the one or more of the second signal or the third signal from the onboard communication device to the second propulsion-generating vehicle via the communication device onboard the first propulsion-generating vehicle.

2. The system of claim 1 , wherein the onboard communication device is included in a distributed power system formed from at least the first propulsion-generating vehicle.

3. The system of claim 1 , wherein the first movement operational setting and the second movement operational setting include one or more of a speed, a throttle setting, or a brake setting.

4. The system of claim 1 , wherein the first off-board control unit is configured to concurrently control different movements of the first propulsion-generating vehicle and the second propulsion-generating vehicle.

5. The system of claim 1 , wherein the first off-board control unit is configured to receive image data representative of an area ahead of a direction of travel of one or more of the first propulsion-generating vehicle or the second propulsion-generating vehicle.

6. The system of claim 1 , wherein the one or more processors are configured to obtain sensor data from an object detection sensor, the sensor data indicative of a presence of an object ahead of at least one of the first propulsion-generating vehicle or the second propulsion-generating vehicle in a direction of travel of the at least one of the first propulsion-generating vehicle or the second propulsion-generating vehicle, and
wherein the one or more processors are configured to prevent the movement of the at least one of the first propulsion-generating vehicle or the second propulsion-generating vehicle toward the object based on the sensor data.

7. The system of claim 1 , wherein the one or more processors are configured to receive a request from one or more of the first off-board control unit or a second off-board control unit to switch remote control of the second propulsion-generating vehicle from the first off-board control unit to the second off-board control unit.

8. The system of claim 7 , wherein the second off-board control unit is configured to be controlled from a location off-board both the first propulsion-generating vehicle and the second propulsion-generating vehicle.

9. The system of claim 1 , wherein the one or more processors are configured to automatically control movement of the first propulsion-generating vehicle according to the first movement operational setting,
wherein the onboard communication device is configured to communicate the one or more of the second signal or the third signal to the second propulsion-generating vehicle for automatic control of movement of the second propulsion-generating vehicle according to the second movement operational setting, and
wherein the first signal is configured to instruct the first propulsion-generating vehicle to move in a first direction and the one or more of the second signal or the third signal is configured to instruct the second propulsion-generating vehicle to concurrently move in an opposite, second direction.

10. A method comprising:
communicatively linking a first off-board control unit with an onboard communication device disposed onboard a first propulsion-generating vehicle;
receiving a first signal at the onboard communication device from the first off-board control unit, the first signal dictating a change in a first movement operational setting of the first propulsion-generating vehicle;
receiving a second signal at the onboard communication device from the first off-board control unit, the second signal dictating a change in a second movement operational setting of a second propulsion-generating vehicle that is separate from the first propulsion-generating vehicle; and
communicating one or more of the second signal or a third signal that is based on the second signal from the onboard communication device to the second propulsion-generating vehicle,
wherein movement of the second propulsion-generating vehicle is configured to be automatically changed responsive to communicating the one or more of the second signal or the third signal from the onboard communication device to the second propulsion-generating vehicle.

11. The method of claim 10 , wherein the onboard communication device is included in a distributed power system formed from at least the first propulsion-generating vehicle.

12. The method of claim 10 , wherein the first signal and the one or more of the second signal or the third signal concurrently control movements of both the first propulsion-generating vehicle and the second propulsion-generating vehicle.

13. The method of claim 10 , wherein the first movement operational setting and the second movement operational setting include one or more of a speed, a throttle setting, or a brake setting.

14. The method of claim 10 , further comprising:
receiving image data at the first off-board control unit, the image data representative of an area ahead of a direction of travel of one or more of the first propulsion-generating vehicle or the second propulsion-generating vehicle; and
visually presenting the image data on an electronic display of the first off-board control unit.

15. The method of claim 10 , further comprising:
obtaining sensor data from an object detection sensor, the sensor data indicative of a presence of an object ahead of one or more of the first propulsion-generating vehicle or the second propulsion-generating vehicle in a direction of travel of the one or more of the first propulsion-generating vehicle or the second propulsion-generating vehicle; and
preventing the movement of the one or more of the first propulsion-generating vehicle or the second propulsion-generating vehicle toward the object based on the sensor data.

16. The method of claim 10 , further comprising:
receiving a request from one or more of the first off-board control unit or a second off-board control unit to switch remote control of the movement of the second propulsion-generating vehicle from the first off-board control unit to the second off-board control unit.

17. The method of claim 10 , wherein the movement of the first propulsion-generating vehicle and the movement of the second propulsion-generating vehicle are automatically changed responsive to receiving the first signal at the onboard communication device and communicating the one or more of the second signal or the third signal from the onboard communication device to the second propulsion-g
