Abstract

Provided are a multimedia system and a method of interfacing a multimedia unit and an audio head unit. The present invention relates to a method in which an audio front panel of a vehicle is detached from a center fascia of the vehicle to secure a free space, and then, in mounting a multimedia unit in the secured free space, the multimedia unit is operably connected to a pure audio head unit through only a wiring without a separate intermediate medium, such as a trip computer, for manipulating the pure audio head unit of the vehicle, and overcomes limitations of the mounting convenience and manipulability of the multimedia unit.

Claims

1. A vehicle multimedia system, comprising:

an audio head unit converting vehicle model information and manipulation key information into protocol signals according to a predefined protocol, and outputting the protocol signals, the manipulation key information corresponding to a pure audio function; and

a multimedia unit analyzing the protocol signals received from the audio head unit to restore the vehicle model information and the manipulation key information according to the predefined protocol, generating an interface image for manipulating the audio head unit in a touch type on the basis of the vehicle model information and the manipulation key information, and displaying the generated interface image, the multimedia unit being directly connected to the audio head unit through a gender.

2. The vehicle multimedia system of claim 1, wherein the multimedia unit comprises:

a controller extracting a plurality of manipulation key items for performing the pure audio function according to the restored vehicle model information and manipulation key information;

an audio interface image generator generating the interface image comprising a plurality of manipulation key images corresponding to the extracted manipulation key items; and

a display visually displaying the generated interface image.

3. The vehicle multimedia system of claim 2, wherein the multimedia unit further comprises a storage storing the interface image generated by the audio interface image generator.

4. The vehicle multimedia system of claim 2, wherein the controller and the audio interface image generator are respectively implemented as software logics, and are mounted on one module.

5. A method of interfacing a multimedia unit and an audio head unit, comprising:

receiving, by the multimedia unit, protocol signals from a pure audio head unit mounted on each of a plurality of vehicles in which the multimedia unit is mounted in a space secured by detaching an audio front panel from a corresponding vehicle, vehicle model information and manipulation key information being converted into the protocol signals according to a predefined protocol;

analyzing, by the multimedia unit, the converted protocol signals to restore the vehicle model information and manipulation key information on each vehicle;

generating, by the multimedia unit, an interface image for manipulating the pure audio head unit of each vehicle in a touch type on the basis of the restored vehicle model information and manipulation key information on each vehicle, the interface image corresponding to each vehicle; and

displaying, when the multimedia unit is mounted on one of the plurality of vehicles, the interface image corresponding to the one vehicle by using a display.

6. The method of claim 5, wherein the generating of an interface image comprises storing a plurality of the interface images by vehicle-model item in a storage of the multimedia unit.

7. The method of claim 6, wherein the displaying of the interface image comprises:

displaying, when the multimedia unit is mounted on one of the plurality of vehicles, a plurality of the vehicle-model items by using the display; and

displaying, by the multimedia unit, when a driver selects a vehicle-model item corresponding to the driver'"'"'s vehicle from among the displayed vehicle-model items, the interface image corresponding to the selected vehicle-model item.
