Abstract

The subject matter of the invention is a process and a system for wireless transmission of infotainment components between an in-vehicle network in a vehicle and a network external to the vehicle, the in-vehicle network having a reception readiness state and an idle state and by way of a remote control of the vehicle can be shifted from the idle state to the reception readiness state. Furthermore the invention relates to a remote control for transmission of a prompt signal, the in-vehicle network by actuating an actuating element of the remote control shifting the in-vehicle network into the reception readiness state, by which infotainment components can be received from a network external to the vehicle.

Claims

1. A system for wireless transmission of infotainment components between an in-vehicle network in a vehicle and a network external to the vehicle, the system comprising an in-vehicle network having a reception readiness state and an idle state and by way of a remote control of the vehicle can be shifted from the idle state to the reception readiness state.

2. The system according to claim 1, wherein the remote control is that of a central locking system of the vehicle.

3. A process comprising shifting the in-vehicle network of the system of claim 2 into the reception readiness state by actuating an actuation element of the remote control.

4. The system according to claim 1, wherein the network external to the vehicle can be connected to the in-vehicle network and can be authenticated relative to the in-vehicle network when the in-vehicle network is ready to receive.

5. A process comprising shifting the in-vehicle network of claim 1 into the reception readiness state for a fixed time interval.

6. The process according to claim 5, wherein the in-vehicle network after a fixed time interval undergoes transition again into the idle state unless a network external to the vehicle is connected to the in-vehicle network.

7. The system process according to claim 6, wherein the in-vehicle network is shifted into the idle state when a connection between the in-vehicle network and a network external to the vehicle is inactive for a fixed time interval.

8. The system of claim 1, wherein a transmitter/receiver of the in-vehicle network is supplied via vehicle battery.

9. The system according to claim 8, wherein the vehicle contains a vehicle battery and a battery management system which is connected to it, which monitors the battery voltage of the vehicle battery and automatically turns off the transmitter/receiver when the battery voltage reaches a low battery voltage.

10. The system according to claim 1, wherein the in-vehicle network and/or the network external to the vehicle are wireless LAN networks.

11. The system according to claim 1, wherein the network external to the vehicle is a home network, and wherein infotainment data can be transmitted from a home PC (1) to the vehicle.

12. The system according claim 11, wherein the infotainment components are media data as well as audio, video and/or multimedia data, and/or navigation data, as well as navigation routes.

13. A method of remotely controlling a motor vehicle for transmission of a prompt signal, the vehicle comprising in-vehicle network having a reception readiness state and an idle state, the method comprising operating the remote control to activate the in-vehicle network by actuating an actuating element of the remote control so that it is shifted into the reception readiness state and can receive infotainment components from a network external to the vehicle.

14. System for transmission of infotainment components, the system comprising:

an in-vehicle network in a motor vehicle, the in-vehicle network having a reception readiness state and an idle state, and

a remote control for the vehicle,

wherein the remote control activates the in-vehicle network when the actuating element of the remote control is actuated so that it is shifted into the reception readiness state, and can receive infotainment components from a network external to the vehicle.

15. The system according to claim 14, wherein the system furthermore comprises a vehicle-side transmitter/receiver for receiving information over the wireless network, the transmitter/receiver being connected to the in-vehicle network, and contains another transmitter/receiver which is connected to a network external to the vehicle.

16. The system according to claim 14, further comprising a network external to the vehicle.

17. A method of operating an in-vehicle network inside a motor vehicle comprising:

receiving a signal to switch the in-vehicle network from an idle state to reception readiness state;

operating a transmitter/receiver connected to the in-vehicle network to communicate with an external network, wherein the external network is outside the vehicle.

18. The method of claim 17, further comprising returning the in-vehicle network to the idle state after a predetermined period of time.

19. The method of claim 17, further comprising generating the signal with a remote control outside the vehicle.

21. The method of claim 17, wherein the operating step comprises transmitting multimedia files.

22. The method of claim 17, further comprising authenticating the external network to the in-vehicle network prior to transmitting files therebetween.

23. The system of claim 22, wherein the switching means comprises a remote control.

24. The system of claim 22, wherein the transferring means comprises a device capable of operating by way of the WLAN, Bluetooth, HiperLAN, ZigBee, nanoNET and Wireless-USB standards.

25. The system of claim 22, further comprising:

a timer, actuated by switching of the in-vehicle network to the reception readiness state; and

means for returning the in-vehicle network to the idle state upon expiration of a preset amount of time.

22-1. A system for transferring data to and from an in-vehicle network comprising:

a vehicle;

an in-vehicle network located in the vehicle;

means for switching the in-vehicle network from an idle state to a reception readiness state; and

means for transferring data between the in-vehicle network and an external network.
