AI Technical Summary

Technical Problem

Existing methods for determining a vehicle's lane location are unreliable, especially in situations where lane markings are missing or temporary obstacles are present, leading to inaccurate lateral guidance.

Method used

A method that combines high-resolution maps and swarm-data-based maps with environmental sensor data to determine lane boundaries, using a boundary detection algorithm and filter algorithms to smooth and adapt to obstacles, and a selection algorithm to choose the most appropriate map based on the vehicle's surroundings.

Benefits of technology

Enables reliable and efficient determination of the vehicle's lane, allowing for precise and adaptive lateral guidance, even in dynamic environments with temporary obstacles or changed lane markings.

Abstract

The invention relates to a method for operating a vehicle function for at least partially automatic control of at least one lateral guidance of a motor vehicle (1), comprising: determining boundary information (20) that describes at least one lane boundary (6) of a lane (3) and / or at least one road boundary (7) of a road (2) that includes the lane (3); providing a high-resolution map (23) and a swarm data-based map (24), wherein a lane center (8, 13) of the lane (3) is shown in the respective map;Fusion of the determined boundary information (20) on the one hand with the high-resolution map (23) or the swarm data-based map (24) on the other hand to determine a target path information (25) that describes a target path (9) of the motor vehicle (1) on the lane (3), wherein a choice between the high-resolution map (23) and the swarm data-based map (24) for the fusion is made by applying a predefined selection algorithm (26); operation of the vehicle function, wherein a trajectory planning (27) of the vehicle function takes the determined target path information (25) into account.
