Embodiment Construction

[0017] figure 1 A device for providing an electronic horizon for a driver assistance system 1 of a motor vehicle is shown. In this case, the device has a position sensor 2 for determining the current position of the motor vehicle. The position sensor 2 may be a GPS or any other suitable satellite-supported or non-satellite-supported positioning system. Furthermore, a data memory 3 is provided in which map information of the road network is stored, preferably in digital form. The position sensor 2 and the data memory 3 can be arranged in a navigation system 4 .

[0018] The current position of the vehicle determined by the position sensor 2 is transmitted as a position signal to the data processing unit 5 . Furthermore, map information is called up from the data memory 3 by the data processing unit 5 . Furthermore, a data processing unit 5 is configured to receive and evaluate data transmitted by radio communication 6 .

[0019] The data processing unit 5 generates data re...

Abstract

The invention relates to a method and a device for providing an electronic horizon for a driver assistance system of a vehicle, wherein the current position of the motor vehicle is determined and the electronic horizon is created by means of a heuristic on the basis of map information of the street network in the surrounding areas of the current position of the motor vehicle. In so doing, a probability consideration of the heuristic is carried out and an accuracy probability of the heuristic is determined.

Description

technical field [0001] The invention relates to a method and a device for providing an electronic horizon for a driver assistance system of a motor vehicle. Background technique [0002] The electronic horizon, which predicts the distance the vehicle will cover in the future, is used as the basis for various assistance or information functions in the vehicle. In this case, the electronic horizon is generated on the basis of map information of the road network surrounding the vehicle's current position by means of heuristics, ie algorithms which are distinguished by low computational effort and short runtime. [0003] DE 10 2005 049 133 discloses a method and a device for providing an electronic horizon for vehicle assistance systems, wherein the electronic horizon is provided in several versions with different information ranges so that it is only passed on to the driver assistance system The information that is needed without too many details that are not needed.
