  • Patent number: 11945439
    Abstract: There is provided mechanisms for AD, or at least ADAS, aided manoeuvring of a vehicle. A method includes selecting between using a CRLS based positioning system and a GNSS based positioning system for aiding manoeuvring of the vehicle. Which positioning system to select is based on comparing a first error determined for the CRLS based positioning system to a second error determined for the GNSS based positioning system. The positioning system with smallest error is selected. The method comprises aiding the manoeuvring of the vehicle using the selected positioning system. The manoeuvring pertains to reversing of the vehicle.

  • Publication number: 20230096655
    Abstract: The disclosure relates to a method for reversing an articulated vehicle combination along a road curvature of a road, comprising obtaining image data representing a rearward view with respect to the articulated vehicle combination, wherein the method further comprises detecting road edges of the road in the image data; determining a plurality of longitudinal and lateral positions of the respective detected road edges; calculating road curvature of the road based on the determined lateral and longitudinal positions; calculating vehicle path curvature to stay on the road; and reversing the articulated vehicle combination by automatically steering the articulated vehicle combination to follow the calculated vehicle path curvature in order to follow the road curvature, wherein the road edges are detected by use of an image analysis algorithm which is based on a plurality of predefined types of road edges of a plurality of different road types.
