Abstract

A method for transmitting travel route information to a person present outside of a motor vehicle, and to a system for transmitting such information. The method for transmitting travel route information to a person present outside of a motor vehicle provides that a navigation system present in the motor vehicle wirelessly transmits a data stream including the information to be transmitted directly or indirectly to a display device carried by the person. The information to be transmitted can be perceived by the person by the display device.

First claim

The invention claimed is:

1. A method for transmitting travel route information for a travel route to a person located outside a motor vehicle, comprising:
storing the travel route comprising a route to a destination in a navigation system located in the motor vehicle;
receiving at least one of a desired departure time and destination arrival time by the person;
receiving traffic information by the navigation system located in the motor vehicle;
evaluating the traffic information based at least in part on the route information as a function of the at least one of the desired departure time and the destination arrival time to determine a favorable departure time;
selecting specific traffic information based at least in part on the evaluation of the traffic information;
storing frequently traveled routes automatically in a memory;
collecting and anonymizing current travel routes of different users;
collect and anonymize planned routes of the different users;
evaluating the current travel routes and planned routes planned for use;
extrapolating route load profiles from the evaluated current and planned travel routes;
determining the travel route information as a function of the received traffic information, frequently occurring traffic situations that occur at certain locations, the extrapolated route load profiles and the travel route by the navigation system located in the motor vehicle;
transmitting data by the navigation system located in the motor vehicle via a data stream containing the travel route information, the specific traffic information, and the favorable departure time in a wireless fashion one of directly and indirectly to a separate playback device carried by the person outside the motor vehicle; and
providing via the playback device at least the favorable departure time and the travel route information determined by the navigation system located in the motor vehicle, the travel route information configured to be perceived by the person via the playback device outside the motor vehicle.

2. The method as claimed in claim 1 , wherein the playback device comprising one of an electronic vehicle key, mobile phone, PDA, and pager.

3. The method as claimed in claim 1 , further comprising:
transmitting by the navigation system a traffic jam signaling function comprising information obtained about instantaneous traffic situation on a planned travel route stored in the navigation system.

4. The method as claimed in claim 1 , wherein the transmission occurs bidirectionally.

5. The method as claimed in claim 1 , wherein the wireless transmission occurs via at least one of an ISM band radio link and a mobile radio link.

6. The method as claimed in claim 5 , wherein the transmission of information takes place by a standard comprising one of WLAN, Bluetooth, GSM, EDGE, HSDPA, and UMTS.

7. The method as claimed in claim 1 , further comprising:
transmission of at least one of the travel route information and the received traffic information via an intermediate connection of a server system;
wherein the server system performs the collecting and anonymizing of the current travel routes of different users planned in the server system, the evaluating the current travel routes planned for use, and the extrapolating route load profiles from the evaluated current travel routes.

8. A system for transmitting travel route information to a person located outside a motor vehicle, comprising:
a navigation system located in the motor vehicle configured to:
store a travel route in the navigation system located in the motor vehicle;
receive traffic information by the navigation system located in the motor vehicle;
receive at least one of a desired departure time and destination arrival time;
storing frequently traveled routes automatically in a memory;
determine the travel route information and a favorable departure time as a function of the received traffic information, frequently occurring traffic situations that occur at certain locations, and the travel route by the navigation system located in the motor vehicle; and
select specific traffic information based at least in part on the evaluation of the traffic information;
a communication device for transmitting data in a wireless fashion;
a server system configured to:
receive at least one of the travel route information and the received traffic information;
collect and anonymize planned routes of different users planned in the server system;
collect and anonymize current travel routes of the different users planned in the server system;
evaluate the current travel routes and planned routes planned for use; and
extrapolate route load profiles from the evaluated current and planned travel routes; and
a separate playback device configured to be carried by the person outside the motor vehicle,
wherein the navigation system is connected by a signaling technology to the communication device such that a data stream that contains the favorable departure time, the specific traffic data, and the travel route information to be transmitted can be sent one of directly and indirectly to the playback device in a wireless fashion via the communication device, and the transmitted information can be perceived on the playback device outside the motor vehicle,
wherein the received traffic information includes the extrapolated route load profiles.

9. The system as claimed in claim 8 , wherein the playback device is one of an electronic vehicle key, mobile phone, PDA and pager.

10. The system as claimed in one of claim 8 , wherein the navigation system has a traffic jam signaling function and information obtained by the traffic jam signaling function related to instantaneous traffic condition on a planned travel route stored in the navigation system is transmitted by the system.

11. The system as claimed in claim 8 , wherein the communication device and the playback device each have at least one of transmitting and receiving devices for the wireless transmission of information by at least one of an ISM band radio link and a mobile radio link.

12. The system as claimed in one of claim 9 , wherein the navigation system has a traffic jam signaling function and information obtained by the traffic jam signaling function related to instantaneous traffic condition on a planned travel route stored in the navigation system is transmitted by the system.

13. The system as claimed in claim 12 , wherein the communication device and the playback device each have at least one of transmitting and receiving devices for the wireless transmission of information by at least one of an ISM band radio link and a mobile radio link.
