Method for determining an assumed motion path traveled by a ground milling machine, and ground milling machine

A method for determining an assumed motion path traveled by a ground milling machine, comprising the steps of:

• a) carrying out a milling task along an actual motion path;
• b) acquiring global navigation satellite system (GNSS) position data using a GNSS signal receiving device and creating GNSS position data sets with the acquired GNSS position data and at least one piece of GNSS signal quality information characterizing the accuracy of the GNSS position data contained in the respective GNSS position data set;
• c) acquiring position change information of the ground milling machine using a local motion detection sensor device of the ground milling machine and creating GNSS-independent local position data sets of the ground milling machine from the position change information, wherein each local position data set comprises, in addition to local position data, at least one piece of local position data quality information characterizing the quality of the local position data contained in the respective local position data set;
• d) determining the assumed motion path of the ground milling machine taking into account the GNSS position data sets and the local position data sets by an evaluation device, wherein GNSS position data and/or local position data are ignored in determining the assumed motion path if:
• they are outside defined maximum difference limits compared to temporally preceding and/or subsequent position data;
• and/or
• their quality information is outside a permissible range.
