CPC G06V 20/588 (2022.01) [G06F 18/22 (2023.01); G06V 10/75 (2022.01)] | 4 Claims |
1. A method for increasing the safety of driving functions in a partially automated or fully autonomous vehicle, including the following steps:
capturing an environment image or a sequence of environment images by means of at least one surroundings detection sensor,
detecting driving lane boundaries in the environment image or the sequence of environment images,
determining a driving lane course based on the detected driving lane boundaries, the driving lane course including a route of the driving lane in front of the vehicle;
retrieving a further driving lane course from a data source;
checking the plausibility of the determined driving lane course by determining whether the determined driving lane course matches the retrieved further driving lane course;
identifying a degree of matching of the determined driving lane course to the retrieved further driving lane course, including verifying a degree of matching of curve radii of curves of the determined driving lane course and the retrieved further driving lane course;
setting a confidence value based on the degree of matching;
providing the determined driving lane course to a driving function when the confidence value is above a predetermined confidence threshold value, the driving function comprising a lane keeping assistant function; and
providing the retrieved further driving lane course to the lane keeping assistant function when the confidence value below the predetermined confidence threshold value is present.
