1. A system incorporated within a vehicle, the system being configured to initiate a telematics service call via a touch-based user interface, the system comprising:

  • a telematics system configured to support communications relating to telematics services;

    an infotainment center;

    a touchscreen interface configured to present user-selectable controls for invoking services provided by;

    the infotainment center, andthe telematics system;

    a backup battery configured to supply power, during a disruption of power supply from a primary power supply, to;

    the touchscreen interface,the telematics system, anda microphone and a speaker providing bi-directional audio communications with providers of telematics services; and

    a backup battery mode control processor configured for;

    sensing a disruption of power provided by the primary power supply, andactivating, in response to the sensing, a low-power operating mode for the touchscreen interface;

    wherein;

    the touchscreen interface includes one or more user-selectable graphical touch-screen soft buttons by which a vehicle occupant requests telematics services, including an emergency call service, in an event of an emergency;

    the one or more user-selectable graphical touch-screen soft buttons remain active during a disruption in power;

    the processor is configured to provide instructions for the one or more user-selectable graphical touch-screen soft buttons to remain active, while a remainder of the touchscreen interface is deactivated, during the low-power operating mode;

    the processor is configured to, while in the low-power operating mode, power only a portion of a display of the touchscreen interface that produces visible images of the one or more user-selectable graphical touch-screen soft buttons, while not powering the remainder of the touchscreen interface;

    the processor is configured to, while in the low-power operating mode, energize only pixels of a portion of a display of the touchscreen interface that produces visible images of the one or more user-selectable graphical touch-screen soft buttons, while not energizing pixels of the remainder of the touchscreen interface; and

    the touchscreen interface uses a matrix of individually-switched self-illuminating diodes that are controllable to emit light without the use of a master backlight, and wherein the processor is configured to, while in the low-power operating mode, energize only pixels formed by triads associated with the one or more user-selectable graphical touch-screen soft buttons, while leaving the remainder of the touchscreen interface unpowered.
