Abstract

A system and method for determining an orientation of a vehicle are provided. The system and method determine (with a sensor assembly disposed onboard a first vehicle) a direction in which a fluid flows within the first vehicle. The first vehicle is included in a vehicle consist with a second vehicle. The orientation of the first vehicle relative to the second vehicle is determined based at least in part on the direction in which the fluid flows within the first vehicle. The fluid may be air in an air brake pipe of the vehicle consist.

Claims

1. A system comprising:

a sensor assembly configured to generate an output representative of a direction in which a fluid flows within a first on-road vehicle that is included in a vehicle consist with a second on-road vehicle; and

one or more processors configured to determine an orientation of the first on-road vehicle relative to the second on-road vehicle based at least in part on the output generated by the sensor assembly,

wherein the one or more processors are configured to change movement of the first on-road vehicle responsive to one or more processors determining the orientation of the first on-road vehicle relative to the second on-road vehicle to move the first on-road vehicle and the second on-road vehicle in a common direction.

2. The system of claim 1, wherein the fluid is in a brake system of the first on-road vehicle.

3. The system of claim 1, wherein the one or more processors are configured to determine the direction in which the fluid flows within the first on-road vehicle prior to the vehicles of the vehicle consist moving.

4. The system of claim 1, wherein the one or more processors are configured to communicatively link the first on-road vehicle with the second on-road vehicle using the orientation that is determined so that the second on-road vehicle can remotely control operation of the first on-road vehicle.

5. The system of claim 1, wherein the sensor assembly is configured to be disposed inside a brake pipe of the first on-road vehicle and to generate the output based at least in part on the direction in which the fluid flows in the brake pipe.

6. The system of claim 1, wherein the sensor assembly is configured to generate the output by measuring one or more characteristics of a brake pipe of the first on-road vehicle in a location that is external to the brake pipe, and wherein the one or more processors are configured to monitor the output generated by the sensor assembly for a change in the one or more characteristics of the brake pipe, wherein the one or more processors are configured to determine the direction in which the fluid flows based at least in part on the change in the one or more characteristics of the brake pipe.

7. The system of claim 6, wherein the one or more characteristics include at least one of strain, temperature, or sound.

8. The system of claim 1, wherein the first and second on-road vehicles are one of automobiles or semi-trailer trucks.

9. The system of claim 8, wherein one of the first on-road vehicle or the second on-road vehicle is configured to automatically control the other of the first on-road vehicle or the second on-road vehicle during movement of the consist relative to a route.

10. A system comprising:

a sensor assembly configured to generate an output representative of a direction in which a fluid flows within a first aerial vehicle that is included in a vehicle consist with a second aerial vehicle; and

one or more processors configured to determine an orientation of the first aerial vehicle relative to the second aerial vehicle based at least in part on the output generated by the sensor assembly,

wherein the one or more processors are configured to change movement of the first aerial vehicle responsive to one or more processors determining the orientation of the first aerial vehicle relative to the second aerial vehicle to move the first aerial vehicle and the second aerial vehicle in a common direction.

11. The system of claim 10, wherein to one or more processors are configured to determine the direction in which the fluid flows within the first aerial vehicle prior to the vehicles of the vehicle consist moving.

12. The system of claim 10, wherein the one or more processors are configured to communicatively link the first aerial vehicle with the second aerial vehicle using the orientation that is determined so that the second aerial vehicle can remotely control operation of the first aerial vehicle.

13. The system of claim 10, wherein the first and second aerial vehicles are aerial drones.

14. The system of claim 10, wherein one of the first aerial vehicle or the second aerial vehicle is configured to automatically control the other of the first aerial vehicle or the second aerial vehicle during movement of the consist relative to a route.

15. A method comprising:

determining, with a sensor assembly disposed onboard a first vehicle that is included in a vehicle consist with a second vehicle, a direction in which a fluid flows within the first vehicle;

determining an orientation of the first vehicle relative to the second vehicle based at least in part on the direction in which the fluid flows within the first vehicle; and

changing movement of the first vehicle responsive to determining the orientation of the first vehicle relative to the second vehicle to move the first vehicle and the second vehicle in a common direction,

wherein the first and second vehicles are one of on-road vehicles or aerial vehicles.

16. The method of claim 15, wherein the first and second vehicles are on-road vehicles and the fluid is in a brake system of the first vehicle.

17. The method of claim 15, wherein determining the direction in which the fluid flows within the first vehicle occurs prior to the vehicles of the vehicle consist moving.

18. The method of claim 15, further comprising communicatively linking the first vehicle with the second vehicle using the orientation that is determined so that the second vehicle can remotely control operation of the first vehicle.

19. The method of claim 15, wherein the first and second vehicles are on-road vehicles, and wherein determining the direction in which the fluid flows includes monitoring flow of the fluid using a sensor of the sensor assembly that is disposed inside a brake pipe of the first vehicle.

20. The method of claim 15, further comprising one of the first vehicle of the second vehicle automatically controlling the other of the first vehicle or the second vehicle during movement of the consist relative to a route.
