Abstract

A method of concurrently communicating data from a vehicle data port to a plurality of computing devices includes a transceiver that handles a plurality of requests from a plurality of independent computing devices. The transceiver is connected to the vehicle data port either directly or indirectly through a pass-thru interface. The plurality of computing devices may each send separate (that is, independent and diverse) requests for data or communications to the vehicle through the transceiver. The transceiver maintains a queue of communications requests from each computing device and orders and sequences the vehicle communications so that timing requirements are properly met and collisions and other types of problems are avoided. The transceiver may also handle duplicative requests by sending only one request to the vehicle data port but providing responses to each requesting computing device.

Claims

1. A method of placing a plurality of independent computing devices in concurrent communication with a single vehicle data port comprising the steps of:

connecting a transceiver in electrical communication with the vehicle data port, the transceiver configured to organize and synchronize vehicle communication requests from the plurality of independent computing devices and to communicate those vehicle communication requests and responses to those vehicle communication requests to and from the vehicle data port in real time;

opening connections between the transceiver and the plurality of computing devices;

concurrently passing a plurality of vehicle communication requests from the plurality of computing devices to the transceiver, upon receipt of which the transceiver processes, prioritizes and sequences the requests in compliance with predetermined vehicle protocol requirements;

sending processed requests to the vehicle data port so that the vehicle may operate on the processed requests and passing back to the transceiver any vehicle communications that incorporate data from the vehicle and are responsive to the processed requests; and

selectively transmitting the responsive vehicle communications from the transceiver to the plurality of computing devices based on which of the plurality of computing devices requested which portions of the responsive vehicle communications;

the transceiver being further configured to identify duplicative requests from the plurality of computing devices, send a single communications request to the vehicle, and provide a response to more than one computing device.

2. The method of claim 1 in which the transceiver is further configured to allow connection and disconnection from the vehicle data port.

3. The method of claim 1 further comprising use of a communications protocol to distribute the vehicle data to the plurality of computing devices.

4. The method of claim 1 further comprising the step of streaming the vehicle data in real time to at least one of the plurality of independent computing devices.

5. The method of claim 1 further comprising the step of providing the vehicle data to at least one of the plurality of independent computing devices in response to a vehicle data request from that independent computing device.

6. The method of claim 1 in which the transceiver is configured to permit the plurality of independent computing devices concurrently to acquire different subsets of vehicle data.

7. The method of claim 1 in which the transceiver maintains a cache of vehicle communications data to permit the plurality of independent computing devices concurrently to acquire certain pieces of vehicle data without waiting for new vehicle communications to take place.

8. The method of claim 1 in which the transceiver is provided as original equipment in the vehicle.

9. The method of claim 1 in which the transceiver is provided as an after-market item for the vehicle.

10. The method of claim 1 in which the electrical communication between the transceiver and the vehicle data port is a direct connection.

11. The method of claim 1 in which the electrical communication between the transceiver and the vehicle data port includes a pass-thru hardware interface.

12. The method of claim 1 in which the electrical communication between the transceiver and the vehicle data port is a wireless connection.

13. The method of claim 1 in which the transceiver is configured to translate vehicle communications protocols such that the plurality of independent computing devices behave as though communicating directly with the vehicle data port without additional adaptation to the computing devices.

14. The method of claim 1 in which the transceiver includes a graphical display or other user interface.

15. A method of placing a plurality of independent computing devices in concurrent communication with a single vehicle data port comprising the steps of:

connecting a transceiver in electrical communication with the vehicle data port, the transceiver configured to organize and synchronize vehicle communication requests from the plurality of independent computing devices and to communicate those vehicle communication requests and responses to those vehicle communication requests to and from the vehicle data port in real time;

opening connections between the transceiver and the plurality of computing devices;

concurrently passing a plurality of vehicle communication requests from the plurality of computing devices to the transceiver, upon receipt of which the transceiver processes, prioritizes and sequences the requests in compliance with predetermined vehicle protocol requirements, which vehicle protocol requirements were originally configured to assume communication with only a single computing device;

sending processed requests to the vehicle data port so that the vehicle may operate on the processed requests and passing back to the transceiver any vehicle communications that incorporate data from the vehicle and are responsive to the processed requests; and

selectively transmitting the responsive vehicle communications from the transceiver to the plurality of computing devices based on which of the plurality of computing devices requested which portions of the responsive vehicle communications.

16. The method of claim 15 further comprising the step of streaming the vehicle data in real time to at least one of the plurality of independent computing devices.

17. The method of claim 15 in which the transceiver maintains a cache of vehicle communications data to permit the plurality of independent computing devices concurrently to acquire certain pieces of vehicle data without waiting for new vehicle communications to take place.

18. The method of claim 15 in which the transceiver comprises at least one of original equipment in the vehicle or an after-market item for the vehicle.

19. The method of claim 15 in which the transceiver is configured to translate vehicle communications protocols such that the plurality of independent computing devices behave as though communicating directly with the vehicle data port without additional adaptation to the computing devices.

20. The method of claim 15 in which the transceiver includes a graphical display or other user interface.
