Abstract

A method for optimizing the provision of a predictive eHorizon in a driver assistance system. A method for providing a predictive eHorizon in a driver assistance system is provided, wherein a horizon provider in a driver assistance system makes information about an expected route course available to an assistance application. The horizon provider creates a planning table including information about the expected route course and/or including data to be provided as a function of the route course, associated with an expected position of the vehicle in the planning table. The planning table data to be provided by the assistance system application are taken at least partially from the planning table as a function of the current position of the vehicle.

Claims

1-7. -7. (canceled)

8. A method for providing a predictive eHorizon in a driver assistance system for a vehicle, comprising:

making information available about an expected route course by an eHorizon provider in a driver assistance system of an assistance system application;

creating, by the eHorizon provider a planning table that contains the information that comprises at least one of;

an expected route course and

data provided as a function of the expected route course and assigned to an expected position of the vehicle;

extracting the information from the planning table to be made available to the assistance system application based at least in part on a vehicle'"'"'s current position.

9. The method as claimed in claim 8, wherein the information stored in the planning table is provided by at least one of:

at least one component of the driver assistance system and a system communicatively connected to the driver assistance system.

10. The method as claimed in claim 8, wherein the information further comprises a most probable path of the vehicle and at least one possible alternative path.

11. The method as claimed in claim 9, further comprising:

calculating the information to be incorporated into the planning table by distributed computing power provided by one or more of;

the eHorizon provider,

the at least one component of the driver assistance system, and

the system communicatively connected to the driver assistance system;

distributing the computing power when less than a definable minimum quantity of the information can be provided by the planning table about a most probable path of the vehicle; and

calculating the information for the most probable path using the distributed computing power.

12. The method as claimed in claim 8, further comprising:

providing the information to an assistance application by extracting the information from the planning table and at least partially directly calculating the information at a time of provision.

13. The method as claimed in claim 8, wherein data extracted from the planning table is provided with an origin marker that identifies the data as being extracted from the planning table.

14. The method as claimed claim 8, further comprising providing additional information relating to paths of other vehicles in a vicinity of the vehicle by the eHorizon provider.

15. The method as claimed in claim 9, wherein the information comprises a most probable path of the vehicle and at least one possible alternative path.

16. The method as claimed in claim 15, further comprising:

calculating the information to be incorporated into the planning table by distributed computing power provided by one or more of;

the eHorizon provider,

the at least one component of the driver assistance system, and

the system communicatively connected to the driver assistance system;

distributing the computing power when less than a definable minimum quantity of the information can be provided by the planning table about a most probable path of the vehicle; and

calculating the information for the most probable path using the distributed computing power.
