Method for checking the plausibility of a trajectory generated on the basis of swarm data for a motor vehicle which is operated in an at least partially assisted manner, computer-readable medium, and assistance system

A non-transitory computer-readable medium storing program code that, when processed by an electronic computing device of a first motor vehicle, causes the electronic computing device to:

• receive swarm data;
• detect a second motor vehicle in a surrounding area of the first motor vehicle;
• determine a driving trajectory of the second motor vehicle;
• compare a trajectory of the first motor vehicle defined by at least two points indicated by the swarm data to the driving trajectory of the second motor vehicle;
• and
• check the trajectory defined by at least two points indicated by the swarm data for plausibility based on a result of comparing the trajectory of the first motor vehicle defined by at least two points indicated by the swarm data to the driving trajectory of the second motor vehicle;
• determine a drivable trajectory for the first motor vehicle based on the trajectory defined by at least two points indicated by the swarm data and the driving trajectory of the second motor vehicle and the comparing;
• determine a validity value that describes a length of a valid drivable trajectory for the drivable trajectory for the first motor vehicle;
• and
• output the validity value, wherein an at least partially automated operation of the first motor vehicle is performed based on the length of the valid drivable trajectory described by the validity value.

An assistance system for checking a trajectory defined by at least two points indicated by swarm data for plausibility for a first motor vehicle operated in at least partially assisted manner, with at least one swarm data receiving device, with a detection device and with an electronic computing device, the assistance system comprising:

• at least one processor;
• and
• a computer-readable medium storing program code that, when processed by the at least one processor, causes the assistance system to:
• receive swarm data;
• detect a second motor vehicle in a surrounding area of the first motor vehicle;
• determine a driving trajectory of the second motor vehicle;
• compare the trajectory of the first motor vehicle defined by at least two points indicated by the swarm data to the driving trajectory of the second motor vehicle;
• check the trajectory defined by at least two points indicated by the swarm data for plausibility based on a result of comparing the trajectory of the first motor vehicle defined by at least two points indicated by the swarm data to the driving trajectory of the second motor vehicle;
• determine a drivable trajectory for the first motor vehicle based on the trajectory defined by at least two points indicated by the swarm data and the driving trajectory of the second motor vehicle and the comparing;
• determine a validity value that describes a length of a valid drivable trajectory for drivable trajectory for the first motor vehicle;
• and
• output the validity value, wherein an at least partially automated operation of the first motor vehicle is performed based on the length of the valid drivable trajectory described by the validity value.
