Abstract

A method of determining the own-vehicle position of a motor vehicle having a navigation system fixedly installed in the motor vehicle includes the steps of: providing a mobile terminal having the suitability for self-localization; providing an interface for the communication-related link-up of the mobile terminal to the motor vehicle; determining the own-terminal position of the mobile terminal by self-localization; transmitting the own-terminal position by way of the interface to the motor vehicle; and taking into account the transmitted own-terminal position when determining the own-vehicle position.

Claims

1. A method of performing vehicle navigation with a fixedly installed navigation system, the method comprising the acts of:

receiving, by the fixedly installed navigation system via an interface, an own-terminal position of a mobile terminal equipped for self-localization, the own-terminal position having been determined by the mobile terminal using a wireless radio network independent of satellite-based signals;

determining, by the fixedly installed navigation system using satellite-based signals, an own-vehicle position of the motor vehicle separately from the determined own-terminal position; and

performing vehicle navigation via the navigation system fixedly installed in the motor vehicle using the own-vehicle position determined using satellite-based signals while simultaneously taking into account the own-terminal position received from and determined by the mobile terminal using the wireless radio network independent of satellite-based signals.

2. The method according to claim 1, wherein the wireless radio network is WLAN.

3. The method according to claim 1, further comprising performing operating input for the vehicle navigation solely via operating devices of the motor vehicle.

4. The method according to claim 3, further comprising the act of:

providing graphic output of the vehicle navigation solely by way of display devices of the motor vehicle.

5. The method according to claim 1, further comprising providing graphic output of the vehicle navigation solely via display devices of the motor vehicle.

6. The method according to claim 1, further comprising the act of:

sending a request from the motor vehicle, via the interface, to the mobile terminal in order to prompt the mobile terminal to transmit the own-terminal position of the mobile terminal for receipt via the interface.

7. The method according to claim 6, further comprising the acts of:

determining a need for receipt of the own-terminal position of the mobile terminal by the motor vehicle;

requesting, by the motor vehicle, the receipt of the own-terminal position of the mobile terminal when it is determined that the need exists.

8. The method according to claim 7, wherein the need exists when a measurement of demand for receiving the own-terminal position exceeds a predefined demand threshold.

9. The method according to claim 1, further comprising the acts of:

determining an accuracy of a position signal present at the motor vehicle, which position signal is based on satellite signals and one or more vehicle sensors;

only receiving the own-terminal position determined by the mobile terminal when the accuracy of the position signal is less than a predefined accuracy threshold.

10. A method of performing vehicle navigation using a navigation system fixedly installed in the motor vehicle, the method comprising the acts of:

receiving, by a mobile terminal via a motor vehicle interface, a request for an own-terminal position determination of the mobile terminal equipped for self-localization;

determining, by the mobile terminal, the own-terminal position of the mobile terminal by the self-localization using a wireless radio network independent of satellite-based signals; and

transmitting the own terminal-position determined independent of satellite-based signals from the mobile terminal to the motor vehicle via the interface, whereby the transmitted own-terminal position is utilizable by the navigation system to perform vehicle navigation in combination with an own-vehicle position of the motor vehicle separately determined by the navigation system using satellite-based signals.

11. The method according to claim 10, wherein the wireless radio network is WLAN.
