Abstract

A control system includes a controller configured to control communication between or among plural vehicle devices that control operation of a vehicle via a network that communicatively couples the vehicle devices. The controller also is configured to control the communication using a data distribution service (DDS) and with the network operating as a time sensitive network (TSN). The controller is configured to direct a first set of the vehicle devices to communicate using time sensitive communications, a different, second set of the vehicle devices to communicate using best effort communications, and a different, third set of the vehicle devices to communicate using rate constrained communications.

First claim

What is claimed is:

1. A control system comprising:
a controller configured to control communication between or among plural vehicle devices that control operation of at least one vehicle via a network that communicatively couples the vehicle devices, the controller configured to control the communication using a data distribution service (DDS) and with the network operating as a time sensitive network (TSN), wherein the DDS comprises an object management middleware communication standard; and
the controller is further configured to determine whether to transmit one or more signals using time sensitive communications, best effort communications, or rate constrained communications based on a type of information to be communicated, wherein the controller is configured to, at least partially in response to determining that the one or more signals control movement of one or more of the plural vehicle devices, direct a first vehicle device of the plural vehicle devices to communicate the one or more signals using the time sensitive communications, and the controller is configured to at least one of:
direct a different, second vehicle device of the plural vehicle devices to communicate using best effort communications; or
direct a different, third vehicle device of the plural vehicle devices to communicate using rate constrained communications.

2. The control system of claim 1 , wherein the network is an Ethernet network at least partially disposed onboard the at least one vehicle.

3. The control system of claim 1 , wherein the vehicle devices include two or more of an input and output device, an engine control unit, a traction motor controller, a display device, an auxiliary load controller, or one or more sensors.

4. The control system of claim 3 , wherein the first vehicle device, which uses the time sensitive communications, comprises the engine control unit or the traction motor controller.

5. The control system of claim 1 , wherein the controller is configured to direct the first vehicle device to communicate using the time sensitive communications such that the time sensitive communications are completed using bandwidth of the network while the second and third vehicle devices communicate the best effort communications and the rate constrained communications using a remaining amount of bandwidth of the network that is not used by the time sensitive communications.

6. The control system of claim 1 , wherein the at least one vehicle comprises a rail vehicle or an automobile.

7. The control system of claim 1 , wherein the controller is further configured to direct a first set of the plural vehicle devices that includes the first vehicle device to communicate using the time sensitive communications, a different, second set of the plural vehicle devices that includes the second vehicle device to communicate using the best effort communications, and a different, third set of the plural vehicle devices that includes the third vehicle device to communicate using the rate constrained communications.

8. A control system comprising:
a controller configured to control communication between plural vehicle devices that control one or more operations of at least one vehicle, the controller configured to control the communication between or among the vehicle devices using a data distribution service (DDS) via an Ethernet network while the Ethernet network operates as a time sensitive network (TSN), wherein the DDS comprises an object management middleware communication standard; and
the controller is further configured to determine whether to transmit one or more signals using time sensitive communications, best effort communications, or rate constrained communications based on a type of information to be communicated, wherein the controller is configured to, at least partially in response to determining that the one or more signals control movement of one or more of the plural vehicle devices, direct a first vehicle device of the plural vehicle devices to communicate the one or more signals using the time sensitive communications, and the controller is configured to at least one of:
direct a different, second vehicle device of the plural vehicle devices to communicate using best effort communications; or
direct a different, third vehicle device of the plural vehicle devices to communicate using rate constrained communications.

9. The control system of claim 8 , wherein the Ethernet network is at least partially disposed onboard the at least one vehicle.

10. The control system of claim 8 , wherein the vehicle devices include two or more of an input and output device, an engine control unit, a traction motor controller, a display device, an auxiliary load controller, or one or more sensors.

11. The control system of claim 10 , wherein the first vehicle device, which uses the time sensitive communications, comprises the engine control unit or the traction motor controller.

12. The control system of claim 8 , wherein the controller is configured to direct the first vehicle device to communicate using the time sensitive communications such that the time sensitive communications are completed using bandwidth of the Ethernet network while the second and third vehicle devices communicate the best effort communications and the rate constrained communications using a remaining amount of bandwidth of the Ethernet network that is not used by the time sensitive communications.

13. The control system of claim 8 , wherein the at least one vehicle comprises a rail vehicle or an automobile.

14. The control system of claim 8 , wherein the controller is further configured to direct a first set of the plural vehicle devices that includes the first vehicle device to communicate using the time sensitive communications, a different, second set of the plural vehicle devices that includes the second vehicle device to communicate using the best effort communications, and a different, third set of the plural vehicle devices that includes the third vehicle device to communicate using the rate constrained communications.

15. A control system comprising:
a controller configured to control communications between plural vehicle devices onboard a vehicle using a data distribution service (DDS) via a time sensitive network (TSN), the DDS comprising an object management middleware communication standard;
wherein the controller is configured to determine whether to transmit one or more signals using time sensitive communications, best effort communications, or rate constrained communications based on a type of information to be communicated, wherein the controller is configured to, at least partially in response to determining that the one or more signals control movement of one or more of the plural vehicle devices, direct a first vehicle device of the plural vehicle devices to communicate the one or more signals using the time sensitive communications, direct a different, second device of the plural vehicle devices to communicate using best effort communications, and direct a different, third device of the plural vehicle devices to communicate using rate constrained communications.

16. The control system of claim 15 , wherein the TSN network is an Ethernet network that is at least partially disposed onboard the vehicle.

17. The control system of claim 15 , wherein the vehicle devices include two or more of an input and output device, an engine control unit, a traction motor controller, a display device, an auxiliary load controller, or one or more sensors.

18. The control system of claim 17 , wherein one or m
