Abstract

A control panel/display subsystem acts as a device portal for interacting with multiple devices interconnected via a dynamic local network. Display content and the human-machine interface (HMI) implemented using the display subsystem automatically reconfigures itself when new devices are added to the vehicle network. An interface specifier enabling each new device to work with the device portal is obtained either from a local archive or a remote archive via connection with a remote network.

Claims

1. An electronic accessory display/control system for a transportation vehicle, comprising:

a reconfigurable control panel having a visual display for displaying menu items for an electronic accessory and having at least one control actuator;

a human-machine interface controller coupled to said reconfigurable control panel and including a local archive for storing a plurality of interface specifiers, each specifier defining interaction between said reconfigurable control panel and a respective electronic accessory for performing operations via said menu items using a predetermined communications protocol;

an expandable interconnection link for coupling compatible electronic accessories with said human-machine interface controller; and

a wireless transceiver for accessing a remote archive of interface specifiers, wherein said remote archive includes interface specifiers each adapted for a corresponding combination of a particular electronic accessory and a particular reconfigurable control panel;

wherein said human-machine interface controller responds to a coupling of an electronic accessory to said expandable interconnection link by checking said local archive for presence of a desired interface specifier corresponding to said electronic accessory and said reconfigurable control panel, and if said desired interface specifier is not present in said local archive then activating said wireless transceiver to automatically obtain said desired interface specifier from said remote archive.

2. The electronic accessory display and control system of claim 1 wherein said desired interface specifier assigns a predetermined function to said control actuator.

3. The electronic accessory display and control system of claim 1 wherein said expandable interconnection link is comprised of a dynamic local network.

4. The electronic accessory display and control system of claim 3 wherein said dynamic local network is comprised of a wireless network, and wherein presence of new electronic accessories is detected automatically in response to a wireless polling signal.

5. The electronic accessory display and control system of claim 1 wherein said compatible electronic accessories each provide to said human-machine interface controller a unique device identifier and a remote network address for said remote archive.

6. The electronic accessory display and control system of claim 1 wherein said interface specifiers are comprised of software objects.

7. The electronic accessory display and control system of claim 6 wherein said software objects include objects to process user events initiated by said control actuator.

8. The electronic accessory display and control system of claim 6 wherein said software objects include objects to process device events corresponding to a state change within said electronic accessory.

9. The electronic accessory display and control system of claim 6 wherein said software objects include objects to render graphics on said visual display.

10. The electronic accessory display and control system of claim 6 wherein said software objects include objects to send predetermined commands to said electronic accessory.

11. The electronic accessory display and control system of claim 1 further including said electronic accessory, and wherein said electronic accessory is comprised of a portable computing device.

12. The electronic accessory display and control system of claim 1 further including said electronic accessory, and wherein said electronic accessory is comprised of a mobile communication device.

13. The electronic accessory display and control system of claim 1 wherein said control actuator is comprised of a push button switch.

14. The electronic accessory display and control system of claim 1 wherein said control actuator is comprised of a speech recognition unit.

15. The electronic accessory display and control system of claim 1 further comprising a memory manager for prioritizing interface specifiers stored in said local archive and deleting interface specifiers of lower priority when said local archive becomes full.

16. A method of operating an electronic accessory display and control system for a transportation vehicle, said system including a reconfigurable control panel, a human-machine interface controller, an expandable interconnection link for compatible electronic accessories, and a wireless transceiver, said method comprising the steps of:

storing a plurality of interface specifiers in a local archive, each interface specifier defining interaction between said reconfigurable control panel and a respective electronic accessory for performing operations via menu items using a predetermined protocol for said reconfigurable control panel;

coupling one of said compatible electronic accessories with said human-machine interface controller via said expandable interconnection link;

checking, in response to said coupling, said local archive for presence of a desired interface specifier corresponding to said compatible electronic accessory and said reconfigurable control panel; and

if said desired interface specifier is not present in said local archive, then activating said wireless transceiver to automatically obtain said desired interface specifier from a remote archive containing an interface specifier adapted for combination of said compatible electronic accessory and said reconfigurable control panel.

17. The method of claim 16 wherein said coupled compatible electronic accessory stores a remote network address of said remote archive.

18. The method of claim 16 further comprising the steps of:

prioritizing said interface specifiers stored in said local archive; and

deleting an interface specifier of lower priority when said local archive becomes full.
