Abstract

A device for connecting communications networks has a safety switch with which two communications networks present in the motor vehicle may be connected by a user. In this connection, in particular, a multimedia network having an air interface, preferably implemented by a mobile phone, is connected to a safety network to which vehicle components are connected that are critical to safety. This connection becomes necessary when a remote diagnosis of the vehicle components or a software update is to be undertaken.

Claims

1. A device for connecting at least two communications networks in a motor vehicle, comprising:

a safety switch for connecting the at least two communications networks.

2. The device according to claim 1, wherein a permanent one-way communication is between the at least two communications networks, the safety switch closing to extend the one-way communication to a duplex communication.

3. The device according to claim 1, wherein the at least two communications networks include a first communications network having an air interface, the air interface being activated by closing the safety switch.

4. The device according to claim 3, wherein the air interface is adapted to receive data when the safety switch is open.

5. The device according to claim 3, wherein the air interface is adapted to receive data only when the safety switch is closed.

6. The device according to claim 3, wherein the air interface automatically contacts an opposite station when the safety switch is closed, the opposite station taking up connection with a second of the at least two communications networks in the motor vehicle.

7. The device according to claim 1, wherein the safety switch is adapted to be closed only by a user.
