Abstract

A method for dynamic destination routing of a vehicle includes the steps of a) determining several routes between a starting point and a destination point; b) determining additional information relevant to the computed routes from additional information which is received from an external transmitting unit and/or is stored in a memory carried along in the vehicle; c) determining the route which is optimal when the additional information is taken into account from the computed routes; and d) outputting destination routing information concerning the optimal route. A system for the destination routing of a vehicle comprises a system part fixedly installed on the vehicle and a portable system part. The system part fixedly installed in the vehicle is connected with the portable system part by way of at least one communication interface. A static destination routing is implemented on the system part fixedly installed in the vehicle and the dynamic processing of the static destination routing is implemented on the portable system part.

Claims

1. A system for destination routing of a vehicle comprising:

a system part mounted on board the vehicle; and

a portable system part;

wherein

the system part mounted on board the vehicle is connectable with the portable system part via at least one communication interface;

a static destination routing is implemented on the system part fixedly installed in the vehicle; and

dynamic processing of the static destination routing is implemented on the portable system part.

2. The system according to claim 1, wherein:

said destination routing includes the steps of

a) a determination of several routes between a starting point and a destination point;

b) a determination of additional information relevant to the computed routes from additional information received from an external transmitting unit and/or stored in a memory on board the vehicle;

c) a determination of a route from among the selected routes, which is optimal when the additional information is taken into account; and

d) an output of destination routing information concerning the optimal route;

at least the Steps a) and d) are performed by the system part on board the vehicle; and

at least the steps b) and c) are performed by the portable system part.

3. The system according to claim 2, wherein the route with the shortest travelling time is determined as optimal.

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

5. The system according to claim 2, wherein the additional information is obtained from several different sources.

6. The system according to claim 2, wherein a check of whether the route recommendation remains optimal is carried out during the drive.

7. The system according to claim 6, wherein:

the check of whether the route recommendation remains optimal comprises a comparison of whether the actual operation parameters of the vehicle correspond to parameters used in determining the optimal route; and

the parameters include at least one of actual traveling time and actually covered distance.

8. The system according to claim 6, 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 6, 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 6, 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 10, wherein the portable system part includes means for determination of the residual route taking into account relevant additional information, including means for

aa) determining several residual routes between the current location and the destination point;

bb) determining additional information relevant to the computed residual routes from additional information which is received from an external transmitting unit or is stored in a vehicle-internal memory;

cc) determining a residual route which is optimal when the additional information is taken into account, from the computed residual routes; and

dd) outputting destination routing information concerning the optimal residual route.

12. The system according to claim 11, wherein:

at least aa) and dd) take place on the system part fixedly installed in the vehicle; and

at least bb) and cc) take place on the portable system part.

13. The system according to claim 2, wherein explanatory information is issued to the driver to increase acceptance of operation of said system.

14. The system according to claims 1, wherein the portable system part comprises a mobile communication device.
