Problems solved by technology

But objects may be occluded and therefore cannot be used to illustrate traffic conditions
Additionally, satellite-based location data and map data for occluded objects are often too inaccurate or outdated to use occluded objects to illustrate traffic conditions

Embodiment Construction

[0019] figure 1 An exemplary traffic situation 100 with a plurality of vehicles is shown in detail. A traffic condition of 100 represents a lane narrowing from two lanes to one lane. Traffic situations 100 occur, for example, at construction sites, accident situations, motorway ends or overtaking areas of arterial roads, where lanes often narrow from two or more lanes to one lane. Through one or more environmental sensors of ego vehicle 102 , ego vehicle 102 may detect motion, ie, position, velocity, and acceleration, of vehicles 104 - 114 in the environment of ego vehicle 102 . In traffic situation 100 , ego vehicle 102 may detect vehicle 104 traveling in the same lane as ego vehicle 102 and inserting itself into a gap between vehicle 108 and vehicle 112 .

[0020] Vehicle 104 changes lanes for this purpose. Additionally, ego vehicle 102 may detect vehicle 106 traveling substantially parallel to ego vehicle 102 . Additionally, ego vehicle 102 may also detect a gap between...

Abstract

The invention relates to a method for operating a driver assistance system of an ego vehicle having at least one surroundings sensor for detecting the surroundings of the ego vehicle, the method comprising: detecting movements of multiple vehicles with the at least one surroundings sensor in the surroundings of the ego vehicle; generating a movement model by means of the detected movements of therespective vehicles, wherein the movement model comprises movements between the respective vehicles relative to one another and movements between the respective vehicles and the ego vehicle; ascertaining a traffic situation and a probability of correct classification of the traffic situation on the basis of the generated movement model by means of an machine learning method, wherein one or more movement features of the generated movement model which are characteristic of the traffic situation are learned by means of the machine learning method, and wherein the traffic situation and the probability of the correct classification of the traffic situation are ascertained by means of the machine learning method on the basis of the learned characteristic features of the movement model; and adapting the driver assistance system of the ego vehicle to the ascertained traffic situation.

Description

technical field [0001] The invention relates to a method for operating a driver assistance system of an autonomous vehicle having at least one environment sensor for detecting the environment of the autonomous vehicle. The invention also relates to a computer-readable medium, a system and a vehicle comprising a system for operating a driver assistance system of an autonomous vehicle having at least one environment sensor for detecting the environment of the autonomous vehicle. Background technique [0002] Current vehicles use objects around the vehicle, location information, or map data to illustrate a situation. Objects around the vehicle are typically illustrated by a model of the vehicle's environment. WO 2010 / 127650 A1 describes a method for processing vehicle sensor data. Evaluation of sensor data with the aid of occupancy grids (Belegungsgitter). DE 10 2006 059 068 A1 describes a method for explaining a traffic situation, in which the position of objects relative t...
