Example Embodiment

[0031] figure 1 A motor vehicle is shown schematically in plan view along an on-ramp to the highway. The highway 1 shown includes a plurality of lanes 2 in this embodiment. The illustrated on-ramp 3 leading to the highway 1 includes only one lane. As an alternative to the illustrated exemplary embodiment, the on-ramp 3 may also include multiple lanes. The expressway 1 has a lane boundary in the form of a crash barrier 4 in the area of ​​the on-ramp 3. The entrance ramp 3 also includes a crash barrier 5. The crash barriers 4 and 5 meet at the transition of the on-ramp 3 in the carriageway area 7 which extends parallel to the lane 2 of the carriageway 1.

[0032] The crash barriers 4 and 5 form an acute angle α in plan view in the area where the crash barrier meets 6. The area 7 of the traffic lane 3 (in which the traffic lane 3 extends parallel to the traffic lane 1) represents the area where the vehicles 10 traveling on the on-ramp 3 can or must merge into the lane 2 of the t...

Abstract

It is determined that (a) a first vehicle is driving on a curve on a first road or, (b) by detecting a second road, a road boundary of the first road. It is further determined that there is (c) parallel traffic by determining that a second vehicle is moving in a lane of the second road adjacent to the first road, or (d) tangential traffic by detecting a third vehicle is moving tangentially to thecurve. Upon determining that there is simultaneously at least one of (a) the first vehicle driving on the curve on the first road or (b) the road boundary of the first road, and at least one of (c) parallel traffic or (d) tangential traffic, then it is determined that the first vehicle is driving on an on-ramp.

Description

technical field [0001] The invention relates to a method for determining the movement of a vehicle on an on-ramp. The invention also relates to a device for determining the movement of a vehicle on an on-ramp. Background technique [0002] Driver assistance systems assist the driver to improve driving comfort and safety while driving. In this case, the properties of the corresponding vehicle environment are important input variables for the individual functions available. With regard to driver assistance systems, in particular Advanced Driver Assistance Systems (ADAS, Advanced Driver Assistance System), features or properties of the roadway and the environment may be features that adapt the corresponding ADAS function to the roadway or environment with respect to the upcoming maneuver s reason. [0003] For example, if the driver wishes to enter a tight gap, exactly depending on whether the driver is on a highway on-ramp or not, the function of the lane change assist can ...
