Abstract
A method detects a lane for a transverse guidance of a vehicle. The transverse guidance of the vehicle is based on a roadway model. The method has the steps of ascertaining one or more features which are suitable for influencing the detection of the lane; detecting a lane on the basis of a sensor system of the vehicle; and ascertaining the roadway model on the basis of the detected lane and the ascertained one or more features. The method optionally has the steps of additionally receiving navigation data and transversely guiding the vehicle on the basis of the ascertained roadway model.
Claims14
A method for detecting a lane for transverse guidance of a vehicle, wherein the transverse guidance of the vehicle is based on a road model, the method comprising:
- determining one or more features, wherein
- the one or more features are suitable for influencing a detection of the lane;
- detecting a lane based on a sensor system of the vehicle;
- determining the road model based on the detected lane and the determined one or more features;
- and
- determining a weighting of one or more elements of the lane that are detected by the sensor system of the vehicle, wherein the road model is also determined based on the determined weighting.
A method for detecting a lane for transverse guidance of a vehicle, wherein the transverse guidance of the vehicle is based on a road model, the method comprising:
- determining one or more features, wherein
- the one or more features are suitable for influencing a detection of the lane;
- detecting a lane based on a sensor system of the vehicle;
- and
- determining the road model based on the detected lane and the determined one or more features, wherein
- if the one or more features indicate presence of an entry or exit on a road section being used by the vehicle, determining the road model comprises:
- weighting elements present on a side of the lane that is remote from the entry or exit using a first factor;
- and
- weighting elements present on a side of the lane that faces the entry or exit using a second factor;
- wherein the first factor indicates a higher weighting than the second factor.
A system for detecting a lane for transverse guidance of a vehicle, comprising:
- a control unit, wherein the control unit is configured to:
- determine one or more features, wherein the one or more features are suitable for influencing a detection of the lane;
- detect a lane based on a sensor system of the vehicle;
- determine a road model based on the detected lane and the determined one or more features;
- and
- determine a weighting of one or more elements of the lane that are detected by the sensor system of the vehicle, wherein the road model is also determined based on the determined weighting.
