Abstract

The invention concerns a multimedia unit with a removable operating section (OS) for a vehicle. The multimedia unit controls and operates functional components for different media and is designed to be permanently installed in the instrument panel of a vehicle. The multimedia unit achieves good protection in a simple manner against theft and unauthorized use, and simplifies the operation of a multimedia unit with any number of functional components. The multimedia unit has a user surface of the removable operating section (OS), which also contains an antenna A2, a microphone MI 1 and a telephone loudspeaker and, is designed as a touch sensitive screen (TS), which in cooperation with a processor in the operating section (OS) and a control and display software generates an interactive user surface (F1) which is adapted to the respective functional component to be operated.

A significant advantage of the invention is that a single operating section of the multifunctional control device not only enables the operation of different functional components in the vehicle, but that it even generates user surfaces which correspond in their optical appearance to that of the known functional components.

Claims

1. A multimedia unit with functional components (RT, BR, AU, GPS-S) for using different media in a vehicle, which includes at least one basic device (BD) and a removable operating section (OS) and where the operating section (OS) comprises:

a radio telephone which can be used independently of the basic device (BD),

a control surface with activation elements (E1 to E9) and at least one display element (D1,D2) for turning on or displaying operating modes of the functional components (RT,BR,AU,GPS-S), and

a processor system (O-μ

P, FLASH 2) with separate control and display software (SW) for operating functional components (RT,BR,AU, GPS-S), characterized in that;

the control surface is a touch sensitive screen (TS) which, in conjunction with the processor system (O-μ

P, FLASH 2) and the control and display software (SW), generates an interactive user surface (F1,F2,F3) which is adapted to the functional component to be switched on in such an intelligent manner, that the latter only has those activation elements (E1 to E8, D1, D2) which refer to the functional components (RT, BR, AU, GPS-S) being switched on,

wherein the functional components include the radio telephone.

2. A multimedia unit as claimed in claim 1, characterized in that the processor system (O-MP, FLASH 2) can operate independently of a main system (M-□

P, FLASH 1) in the basic device (BD), and in conjunction with the touch sensitive screen (TS) directly controls the telephone module (RT) and controls at least indirectly the operation and display for the functional components (RT, BR, AU, GPS-S) of the multimedia unit.

3. A multimedia unit as claimed in claim 1, characterized in that the control and display software (SW) advantageously contains individual software components for the corresponding functional components of the multimedia unit, which are installed with the functional components (RT, BR, AU, GPS-S) in accordance with the extent of the multimedia unit equipment.

4. A multimedia unit as claimed in claim 3, characterized in that the operating section (OS) has means whereby the installed control and display software (SW) can be added to and expanded for individual functional components.

5. A multimedia unit as claimed in claim 1, characterized in that at least the processor system (O-μ

MP, FLASH 2) of the operating section (OS) and the main system (M-μ

MP, FLASH 1) of the basic device (BD) have recognition software for reciprocal identification.

6. A multimedia unit as claimed in claim 1, characterized in that the basic device (BD) contains means (EB, S, M-μ

MP, RT 2, BO, A3) to establish a radio telephone connection to a service which can make help and/or emergency calls without the cooperation of the operating section (OS).

7. A multimedia unit as claimed in claim 1, characterized in that after the operating section (OS) is coupled to the basic device (BD), the processor system (O-μ

MP, FLASH 2) provides a first interactive user surface (F1) with a main menu from which a functional component (RT, BR, AU, GPS-S) can be selected, so that other interactive user surfaces (F2, F3) can then be called up for the touch sensitive screen (TS) to operate the selected functional component, where the surface structure, functionality and appearance are optimally adapted for the selected functional component (RT, BR, AU, GPS-S).

8. A multimedia unit as claimed in claim 1, characterized in that when the operating section (OS) is removed from the basic device (BD), the processor system (O-μ

MP, FLASH 2) adapts the structure and the appearance of the interactive user surface (F1, F2) to the user surface (F3) that is familiar to a radio telephone user.

9. A multimedia unit as claimed in claim 8, characterized in that when the operating section (OS) is removed from the basic device (BD), the touch sensitive screen (TS) changes the reading characters on the user surface (F3) from horizontal to vertical.

10. A multimedia unit as claimed in claim 1, characterized in that the processor system (O-μ

MP, FLASH 2) contains software means (SW) which also provide the corresponding user surfaces (F2, F3) for different functional components (RT, BR, AU, GPS-S) in the removed mode, so that presetting can be programmed and stored without coupling to the basic device (BD).

11. A multimedia unit as claimed in claim 10, characterized in that data communication between the main system in the basic device (BD) and the processor system in the operating section (OS) takes place via a wireless data connection (BUS 1), so that the uncoupled operating section (OS) can be used to interactively operate components in the multimedia unit.

12. A multimedia unit as claimed in claim 11, characterized in that a radio interface is used for the data communication between the basic device (BD) and the operating section (OS).

13. A multimedia unit as claimed in claim 11, characterized in that the operating section (OS) is also designed as an interactive remotely controlled transmitter for other additional functions in connection with the vehicle.

14. A multimedia unit as claimed in claim 1, characterized in that data communication between the main system in the basic device (BD) and the processor system in the operating section (OS) takes place via a wireless data connection (BUS 1), so that the uncoupled operating section (OS) can be used to interactively operate components in the multimedia unit.
