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 determining an own-vehicle position of a motor vehicle with a fixedly installed navigation system, the method comprising the acts of:

receiving, 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; and

determining an own-vehicle position of the motor vehicle factoring into account the received own-terminal position of the mobile terminal.

2. The method according to claim 1, wherein the received own-terminal position of the mobile terminal was based on self-localization of the mobile terminal based upon a wireless radio network.

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

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

performing vehicle navigation via the navigation system fixedly installed in the motor vehicle using the own-vehicle position determined while taking into account the received own-terminal position; and

performing operating input for the vehicle navigation solely via operating devices of the motor vehicle.

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

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

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

performing vehicle navigation via the navigation system fixedly installed in the motor vehicle using the own-vehicle position determined while taking into account the received own-terminal position; and

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

7. 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.

8. The method according to claim 7, 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.

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

10. 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.

11. A method of determining an own-vehicle position of a motor vehicle having a navigation system fixedly installed in the motor vehicle, the method comprising the acts of:

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

determining the own-terminal position of the mobile terminal by the self-localization; and

transmitting the own terminal-position from the mobile terminal to the motor vehicle via the interface, whereby the transmitted own-terminal position is utilizable for determining the own-vehicle position of the motor vehicle.

12. The method according to claim 11, wherein the act of determining the own-terminal position is based on a wireless radio network.

13. The method according to claim 12, wherein the wireless radio network is WLAN.
