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

A device including a computing unit, configured to create a digital map representing one or more traffic routes, each traffic route including traffic route segments, the device configured to:

• retrieve map data values representing a base map, the base map including traffic infrastructure information for the traffic route segments individually;
• determine tolerance specifications for each individual traffic route segment based on the traffic infrastructure information, the tolerance specifications representing a maximum permissible deviation of independently determined positions;
• create the digital map by adding the predetermined tolerance specifications for the individual traffic route segments to the traffic infrastructure information;
• and
• provide the digital map for operating an automated vehicle.

A non-transitory machine-readable storage medium on which is stored a computer program for creating a digital map representing one or more traffic routes, each traffic route including traffic route segments, the computer program, when executed by a computer, causing the computer to perform the following steps:

• retrieving map data values representing a base map, the base map including traffic infrastructure information for the traffic route segments individually;
• determining tolerance specifications for each individual traffic route segment based on the traffic infrastructure information, the tolerance specifications representing a maximum permissible deviation of independently determined positions;
• creating the digital map by adding the predetermined tolerance specifications for the individual traffic route segments to the traffic infrastructure information;
• and
• providing the digital map for operating an automated vehicle.

A method for operating an automated vehicle, comprising the following steps:

• determining a first position of the automated vehicle;
• determining a second position of the automated vehicle;
• determining a difference between the first position and the second position;
• determining a maximum permissible deviation using a digital map, the digital map being created by:
• retrieving map data values representing a base map, the base map including traffic infrastructure information for the traffic route segments individually,
• determining tolerance specifications for each individual traffic route segment based on the traffic infrastructure information, the tolerance specifications representing a maximum permissible deviation of independently determined positions, and
• creating the digital map by adding the predetermined tolerance specifications for the individual traffic route segments to the traffic infrastructure information;
• comparing the difference with the maximum permissible deviation;
• determining a driving strategy based on the comparison;
• and
• operating the automated vehicle based on the driving strategy.
