Abstract

Systems and methods for reconfigurable on-vehicle data routing are provided. In one embodiment, a data link communication system comprises: a router to communicate with at least one communication bus and at least one data bus, and monitor data communicated over the communication data buses, wherein the communication bus communicates data link messages with an off-vehicle service provider system, wherein the data bus transports data between the router and a plurality of on-vehicle systems; a routing control logic; and a conditional logic database, wherein the database comprises definitions of one or more datatypes and definitions for at least one data forwarding command; wherein, in response to receiving a first set of data associated with a datatype defined by the database, the logic executes the at least one data forwarding command to control the router to output a second set of data to one or more of the plurality of on-vehicle systems.

First claim

What is claimed is:

1. A data link communication system for a vehicle, the data link communication system comprising:
a data link communications router configured to communicate with at least one on-vehicle communication bus and at least one on-vehicle data bus, and monitor data communicated over the at least one on-vehicle communication bus and the at least one on-vehicle data bus, wherein the at least one on-vehicle communication bus is configured to communicate data link messages with at least one off-vehicle service provider system, wherein the at least one on-vehicle data bus is configured to transport data to and between on-vehicle systems;
a routing control logic; and
a conditional logic database coupled to the routing control logic, wherein the conditional logic database comprises definitions which include definitions of one or more datatypes and a definition for a data forwarding command utilized by the routing control logic to forward data to a second on-vehicle system;
wherein, in response to the data link communication system receiving, from a first on-vehicle system, a first set of data associated with a datatype defined by the conditional logic database, the routing control logic is configured to execute the data forwarding command to control the data link communications router to transmit a second set of data to the second on-vehicle system;
wherein the first set of data is derived from an uplink message received by the data link communication system from the at least one off-vehicle service provider system via the at least one on-vehicle communication bus;
wherein the second set of data is based on the first set of data.

2. The data link communication system of claim 1 , wherein the routing control logic is configured to execute the data forwarding command, defined by the conditional logic database, to synchronize the second on-vehicle system with the first on-vehicle system.

3. The data link communication system of claim 1 , wherein the routing control logic executes a process to generate at least part of the second set of data in response to receiving the first set of data.

4. The data link communication system of claim 3 , wherein the process comprises an application hosted on the data link communication system.

5. The data link communication system of claim 1 , wherein the second set of data is output to an application hosted on the data link communication system.

6. The data link communication system of claim 1 , wherein the data forwarding command is defined in terms of a first parameter that indicates a content of the second set of data and a second parameter that indicates a destination that identifies the second on-vehicle system which will receive the second set of data indicated by the first parameter.

7. The data link communication system of claim 1 , wherein the routing control logic is configured to perform deep packet inspection on the first set of data to determine a first datatype of the first set of data and executes the data forwarding command based on the first datatype.

8. The data link communication system of claim 1 , wherein the routing control logic is configured to read a message identifier from the first set of data to determine a first datatype of the first set of data and execute the data forwarding command based on the first datatype.

9. The data link communication system of claim 1 , wherein the routing control logic is configured to format the second set of data based on a format defined by the conditional logic database.

10. The data link communication system of claim 1 , wherein the vehicle comprises one of an aircraft, spacecraft, watercraft, train, truck, or automobile.

11. The data link communication system of claim 1 , wherein the definitions of one or more datatypes and the definition for the data forwarding command in the conditional logic database are reconfigurable.

12. A method for a data link communication system for a vehicle, the method comprising:
determining with a routing control logic at least one datatype associated with a first set of data received at an on-vehicle data link communications router from a first on-vehicle system, wherein the on-vehicle data link communications router is coupled to at least one data bus configured to transport data between on-vehicle systems, and wherein the on-vehicle data link communications router is further coupled to at least one on-vehicle communication bus configured to communicate data link messages with one or more off-vehicle service provider systems;
determining, based on the at least one datatype, a data forwarding command defined by an onboard conditional logic database coupled to the routing control logic; and
executing the data forwarding command at the routing control logic, wherein executing the data forwarding command controls the on-vehicle data link communications router to transmit a second set of data based on the first set of data to a second on-vehicle system identified by the onboard conditional logic database;
wherein the first set of data is derived from an uplink message received by the data link communication system from the one or more off-vehicle service provider systems via the at least one on-vehicle communication bus;
wherein the second set of data is based at least in part from the first set of data.

13. The method of claim 12 , further comprising executing, with the routing control logic, the data forwarding command defined by the onboard conditional logic database to synchronize the second on-vehicle system with the first on-vehicle system.

14. The method of claim 12 , further comprising executing, with the routing control logic, a process applied to the first set of data to generate at least part of the second set of data.

15. The method of claim 12 , further comprising formatting, with the routing control logic, the second set of data based on a format defined by the onboard conditional logic database.
