Abstract

In a system for the destination routing of a vehicle, a route is determined which is optimal based on input vehicle position and destination information and on stored information, and taking into account additional information; and destination routing information is issued with respect to the optimal route. The additional information is received by an external transmitting unit and/or is stored in a memory on board the vehicle. A check takes place during the drive as to whether the route recommendation remains optimal, and a further optimal route determination is triggered if it does not.

Claims

1. A system for the destination routing of a vehicle, in which a route recommendation is determined that is optimal based on input vehicle position and destination information and stored information, and taking into account additional information;

and destination routing information is issued with respect to the optimal route, the additional information being received by an external transmitting unit or being stored in a memory on board the vehicle, wherein;

during the drive a check is made whether the route recommendation remains optimal, based on a comparison of whether real travel parameters of the vehicle correspond to the parameters used when determining the optimal route;

a determination that the route recommendation does not remain optimal triggers a new optimal route determination; and

the travel parameters include at least one of travel time and traveled distance.

2. The system according to claim 1, wherein a new optimal route determination is also triggered by a receipt of new additional information.

3. The system according to claim 1, wherein the route with the shortest traveling time is determined to be optimal.

4. The system according to claim 1, wherein the additional information comprises traffic information.

5. The system according to claim 2, wherein the additional information comprises traffic information.

6. The system according to claim 3, wherein the additional information comprises traffic information.

7. The system according to claim 1, wherein the additional information is obtained from several different sources.

8. The system according to claim 1, wherein the check of whether the route recommendation remains optimal comprises an evaluation of at least one of quality and quantity of the additional information.

9. The system according to claim 1, wherein the check of whether the route recommendation remains optimal takes into account that, during the drive, additional information relevant to a residual route to be driven is determined from additional information that is received from an external transmitting unit or is stored in a vehicle-internal memory.

10. The system according to claim 1, wherein, as a result of checking whether the route recommendation remains optimal, a determination of a residual route is triggered, taking into account relevant additional information.

11. The system according to claim 1, wherein, for increasing the acceptance of recommendation information by the driver, explanatory information is issued to the driver.

12. The system according to claim 1, wherein:

the system comprises a system part fixedly installed in the vehicle and a portable system part; and

the system part fixedly installed in the vehicle is connected with the portable system part via at least one communication interface.

13. The system according to claim 12, wherein a static destination routing is carried out on the system part fixedly installed in the vehicle, and a dynamic destination routing is carried out on the portable system part.

14. The system according to claim 12, wherein the portable system part comprises a mobile communication device.

15. A system for the destination routing of a vehicle, comprising:

a first part fixedly installed in the vehicle, the first part determining an optimal route; and

a second portable part coupled to the first part, the second part receiving the optimal route from the first part and determining a new optimal route;

wherein,

the second part determines a new optimal route based on a comparison of real travel parameters of the vehicle and travel parameters associated with the determined optimal route; and

the travel parameters include at least one of travel time and traveled distance.

16. The system of claim 15, wherein the second portable part determines a new optimal route while the second part is located within the vehicle.

17. The system of claim 15, wherein the second part determines the new optimal route based on additional information, and the first part comprises an output which outputs a source of the additional information.

18. The system of claim 15, wherein the first part is coupled to the second part using a wireless Bluetooth connection.

19. A method for destination routing of a vehicle, the method comprising the acts of:

determining, based on static information, an optimal route;

receiving additional information;

determining, based on a comparison of real travel parameters of the vehicle with travel parameters associated with the optimal route, whether the optimal route remains optimal; and

determining a new optimal route when the optimal route does not remain optimal, wherein the new optimal route is determined using the additional information,

wherein the travel parameters include at least one of travel time and traveled distance.

20. The method of claim 19, wherein the determination of the optimal route and the new optimal route are performed within the vehicle.

21. The method of claim 19, further comprising the act of:

outputting a source of the additional information, wherein the source of the additional information includes at least one of Radio Data System (RDS), RDS/Traffic Message Channel (RDS/TMC), control-center-supported services, internet-based and Wireless Application Protocol-based (WAP) services.
