Abstract

Embodiments of the present invention include systems and methods for a computer-implemented, in-vehicle application platform (VAP) for conducting vehicle-to-business (V2B) communication. A V2B vehicle application layer resides within the vehicle. The VAP comprises a communication layer facilitating reliable message exchange between this vehicle application layer and V2B business applications. The VAP further comprises a HW abstraction layer encapsulating vehicle-specific interfaces both with regard to the CAN bus and the in-vehicle HMI. According to certain embodiments, these layers of the VAP provide their functionality via open, non-proprietary, and well-defined interfaces, allowing for efficient development of V2B applications and enhancing portability of the latter.

Claims

1. A computer-implemented method comprising:

placing a vehicle-to-business software application present within a vehicle, into publish/subscribe communication with a service provider through a message broker of a vehicle application platform also present within the vehicle; and

causing the message broker to buffer messages to be delivered to the service provider that cannot be delivered due to a temporary communication disconnection between the vehicle and the service provider.

2. The method of claim 1 further comprising causing the message broker to reschedule delivery of messages to the service provider.

3. The method of claim 1 further comprising causing the message broker to assign a priority to messages to the service provider.

4. The method of claim 3 wherein the assignment of the priority is based upon a certificate assigned to the vehicle-to-business software application.

5. The method of claim 3 further comprising causing the message broker to deliver messages to a business application based upon the assigned priority.

6. The method of claim 1 further comprising causing the message broker to invoke the vehicle-to-business software application based upon a message header extended by a pre-defined set of metadata.

7. The method of claim 1 further comprising:

placing the vehicle-to-business software application into communication with a human machine interface of the vehicle, through an XML-based bi-directional interface provided by the vehicle application platform; and

causing the XML-based bi-directional interface to reference a defined XML schema comprising, elements to be displayed, related actions, or input required from a user of the vehicle.

8. A non-transitory computer readable storage medium embodying a computer program for performing a method, said method comprising:

placing a vehicle-to-business software application present within a vehicle, into publish/subscribe communication with a service provider through a message broker of a vehicle application platform also present within the vehicle; and

causing the message broker to buffer messages to be delivered to the service provider that cannot be delivered due to a temporary communication disconnection between the vehicle and the service provider.

9. The computer readable storage medium of claim 8 wherein the method further comprises causing the message broker to reschedule delivery of messages to the service provider.

10. The computer readable storage medium of claim 8 wherein the method further comprises causing the message broker to assign a priority to messages to the service provider.

11. The computer readable storage medium of claim 10 wherein the assignment of the priority is based upon a certificate assigned to the vehicle-to-business software application.

12. The computer readable storage medium of claim 10 wherein the method further comprises causing the message broker to deliver messages to a business application based upon the assigned priority.

13. The computer readable storage medium of claim 8 wherein the method further comprises causing the message broker to invoke the vehicle-to-business software application based upon a message header extended by a pre-defined set of metadata.

14. The computer readable storage medium of claim 8 wherein the method further comprises:

placing the vehicle-to-business software application into communication with a human machine interface of the vehicle, through an XML-based bi-directional interface provided by the vehicle application platform; and

causing the XML-based bi-directional interface to reference a defined XML schema comprising, elements to be displayed, related actions, or input required from a user of the vehicle.

15. A computer system comprising:

one or more processors;

a software program, executable on said computer system, the software program configured to;

place a vehicle-to-business software application present within a vehicle, into publish/subscribe communication with a service provider through a message broker of a vehicle application platform also present within the vehicle; and

cause the message broker to buffer messages to be delivered to the service provider that cannot be delivered due to a temporary communication disconnection between the vehicle and the service provider.

16. The computer system of claim 15 wherein the software program is further configured to cause the message broker to reschedule delivery of messages to the service provider.

17. The computer system of claim 15 wherein the software program is further configured to cause the message broker to assign a priority to messages to the service provider.

18. The computer system of claim 17 wherein the assignment of the priority is based upon a certificate assigned to the vehicle-to-business software application.

19. The computer system of claim 17 wherein the software program is further configured to cause the message broker to deliver messages to a business application based upon the assigned priority.

20. The computer system of claim 15 wherein the software program is further configured to cause the message broker to invoke the vehicle-to-business software application based upon a message header extended by a pre-defined set of metadata.
