Method and device for creating a digital map and for operating an automated vehicle

A device, comprising:

• a control device configured to operate an automated vehicle along a traffic route, the control device configured to:
• detect boundary features of the traffic route, wherein the boundary features are detected using at least one video sensor of the automated vehicle;
• detect a surrounding area of the automated vehicle along the traffic route, wherein the surrounding area is detected using at least one radar sensor of the automated vehicle;
• provide a digital map which includes a first sub-map and a second sub-map, wherein the first sub-map corresponds to a radar map which includes surrounding area features in the surrounding area along the traffic route via a radar signature, and wherein the second sub-map includes boundary features via a video signature;
• determine a first position of the automated vehicle by performing a first comparison that compares the detected surrounding area with the first sub-map;
• determine a second position of the automated vehicle by correcting a lateral deviation of the first position using a second comparison that compares the detected boundary features with the second sub-map, wherein the second position retains a longitudinal position of the automated vehicle identified in the first position and includes a lateral position of the automated vehicle determined from the second comparison;
• and
• operate the automated vehicle along the traffic route depending on the second position.

A non-transitory machine-readable storage medium on which is stored a computer program for operating an automated vehicle along a traffic route, the computer program, when executed by a computer, causing the computer to perform the following steps:

• detecting boundary features of the traffic route, wherein the boundary features are detected using at least one video sensor of the automated vehicle;
• detecting a surrounding area of the automated vehicle along the traffic route, wherein the surrounding area is detected using at least one radar sensor of the automated vehicle;
• providing a digital map which includes a first sub-map and a second sub-map, wherein the first sub-map corresponds to a radar map which includes surrounding area features in the surrounding area along the traffic route via a radar signature, and wherein the second sub-map includes boundary features via a video signature;
• determining a first position of the automated vehicle by performing a first comparison that compares the detected surrounding area with the first sub-map;
• determining a second position of the automated vehicle by correcting a lateral deviation of the first position using a second comparison that compares the detected boundary features with the second sub-map, wherein the second position retains a longitudinal position of the automated vehicle identified in the first position and includes a lateral position of the automated vehicle determined from the second comparison;
• and
• operating the automated vehicle along the traffic route depending on the second position.
