Abstract

A method for controlling devices in a communications network in a motor vehicle and a device in a communications network in a motor vehicle are proposed, which are used to control newly added devices. To that end, a generic control module and data stored in the device are used to generate a device-specific control component, which can be used to control the device. The device-specific control component can either be added to the generic control module or can be stored independently of the generic control module in the respective device. The generic control module is used in a gateway or a system manager of the communications network. The human-machine interface is adapted by means of the device-specific control component. A bus system, preferably embodied according to IEEE 1394, is used as the technology for the communications network. The essential advantage of the invention is the self-configurability of the communications network and its devices.

Claims

1. A method for controlling devices, which are connected to a communications network in a motor vehicle, wherein an operating software is provided on a device of the communications network, characterized in that the operating software has a generic control module added to it, that the generic control module and data stored in at least one additional device of the communications network are used to generate a device-specific control component for the at least one additional device, and that the device-specific control component can be used to control the at least one additional device.

2. The method according to claim 1, characterized in that the device-specific control component is used independently of the generic control module.

3. The method according to claim 1, characterized in that the device-specific control component is added to the generic control module.

4. The method according to claim 2 or 3, characterized in that the generic control module is used in a gateway (4, 8) of the communications network.

5. The method according to one of the preceding claims, characterized in that the human-machine interface in the motor vehicle is adapted by means of the device-specific control component.

6. The method according to one of the preceding claims, characterized in that a bus system (7, 10) is used as the communications network.

7. The method according to claim 6, characterized in that an IEEE 1394 bus system is used as the bus system (7, 10).

8. The method according to one of the preceding claims, characterized in that functions, which are comprised of at least one command and are for controlling the additional devices, are stored in an automatically processable language in the at least one additional device, as are parameters, value ranges, resolutions, and chronological relationships.

9. A device in a communications network in a motor vehicle, wherein the device has an operating software, characterized in that the operating software has a generic control module, which can be used to call up data stored in at least one additional device of the communications network and can be used to generate a respective device-specific control component for the at least one additional device, and that the device-specific control component can be used to control the at least one additional device.

10. The device according to claim 9, characterized in that the device, which has the operating software, is a gateway (4, 8).

11. Another device according to claim 9 or 10, characterized in that the at least one additional device has memory containing device-specific data, wherein the data can be called up via the communications network in the motor vehicle, and that the data can be used to generate the device-specific control component.
