Abstract

A data communication system for a vehicle includes an interface gateway device that is configured to be communicatively coupled with a data acquisition module and a client module. The interface gateway device is further configured to receive a value of a data parameter related to operation of the vehicle from the data acquisition module and to communicate the value to the client module for performing a function for the vehicle. The interface gateway device also is configured to determine when either of the data acquisition module or the client module is communicatively coupled with the interface gateway device and to implement respective communication configurations associated with the data acquisition module or the client module to receive the value of the data parameter from the data acquisition module or communicate the value of the data parameter to the client module.

wherein the interface gateway device is configured to determine when either of the data acquisition module or the client module is communicatively coupled with the interface gateway device and to implement respective communication configurations associated with the data acquisition module or the client module to receive the value of the data parameter from the data acquisition module or communicate the value of the data parameter to the client module.

2. The system of claim 1, wherein the interface gateway device is configured to communicate the value of the data parameter to the client module for the client module to use the value of the data parameter to control at least one of tractive effort or braking effort provided by the vehicle.

3. The system of claim 1, wherein the interface gateway device is configured to determine when either of the data acquisition module or the client module is physically mated with one or more input/output ports of the interface gateway device.

4. The system of claim 1, wherein the interface gateway device is configured to determine when either of the data acquisition module or the client module is communicatively coupled with the interface gateway device by a wireless communication link.

5. The system of claim 1, wherein the interface gateway device is configured to determine an identity of either of the data acquisition module or the client module that is communicatively coupled with the interface gateway device.

6. The system of claim 5, wherein the interface gateway device is configured to select at least one of a plurality of communication configurations from a computer readable storage medium for use in communicating with the data acquisition module or the client module based on the identity.

7. The system of claim 6, wherein the communication configurations specify different communication protocols used to communicate with different data acquisition modules or different client modules.

8. A data communication system for a vehicle, the system comprising:

an interface gateway device configured to be communicatively coupled with a data acquisition module and with a client module, wherein the interface gateway device, the data acquisition module, and the client module are configured to be disposed onboard the vehicle, wherein the interface gateway device is further configured to receive a value of a data parameter related to operation of the vehicle from the data acquisition module and to communicate the value to the client module for performing a function for the vehicle;

wherein the interface gateway device is configured, upon system initialization of the interface gateway device, to cycle through a plurality of communication protocols available to the interface gateway device, at each of a plurality of communication links of the interface gateway device, until the interface gateway device has determined that the data acquisition module and the client module are communicatively coupled with the interface gateway device and has identified first and second communication protocols of the plurality of communication protocols that enable the interface gateway device to communicate with the data acquisition module and the client module, respectively.

9. A method for communicating data in a vehicle, the method comprising:

disposing a device onboard the vehicle, the device including one or more of a data acquisition module or a client module;

monitoring one or more input/output ports for a communication link with the device;

determining an identity of the device that is communicatively coupled with the one or more input/output ports by the communication link;

selecting a communication configuration associated with the device based on the identity of the device;

using the communication configuration to communicate with the device; and

one or more of the data acquisition module acquiring values of data parameters related to operations of the vehicle or the client module performing one or more functions for the vehicle based on the values of the data parameters.

10. The method of claim 9, wherein the method further comprises the client module controlling at least one of tractive effort or braking effort of the vehicle based on the values of the data parameters.

11. The method of claim 9, wherein the monitoring step includes determining when the device is physically mated with the one or more input/output ports.

12. The method of claim 9, wherein the monitoring step includes determining when the device is communicatively coupled with the one or more input/output ports by a wireless communication link.

13. The method of claim 9, wherein the selecting step includes selecting the communication configuration from a plurality of communication configurations stored on a computer readable storage medium based on the identity of the device.

14. The method of claim 13, wherein the communication configurations specify different communication protocols used to communicate with different devices.

15. A non-transitory computer readable storage medium for a vehicle having one or more processors, the non-transitory computer readable storage medium including one or more sets of instructions that direct the one or more processors to:

monitor one or more input/output ports for a communication link with a device, the device including at least one of a data acquisition module or a client module, wherein the data acquisition module and the client module are disposed onboard a vehicle;

determine an identity of the device that is communicatively coupled with the one or more input/output ports by the communication link;

select a communication configuration associated with the device based on the identity of the device; and

communicate with the device according to the communication configuration by at least one of receiving values of data parameters related to operations of the vehicle from the data acquisition module or communicating one or more of the values to the client module so that the client module performs one or more functions for the vehicle based on the values of the data parameters.

16. The non-transitory computer readable storage medium of claim 15, wherein the one or more sets of instructions direct the one or more processors to communicate values of data parameters related to operations of the vehicle to the client module so that the client module controls at least one of tractive effort or braking effort of the vehicle based on the values of the data parameters.

17. The non-transitory computer readable storage medium of claim 15, wherein the one or more sets of instructions direct the one or more processors to determine when the device is physically mated with the one or more input/output ports.

18. The non-transitory computer readable storage medium of claim 15, wherein the one or more sets of instructions direct the one or more processors to determine when the device is communicatively coupled with the one or more processors by a wireless communication link.
