Method, Device, Computer Program and Computer Program Product for Operating a Vehicle, and Vehicle

A method for operating a vehicle having

• a communication interface designed to interchange data with a database arranged externally to the vehicle,
• a position determination unit designed to ascertain a vehicle position value that is representative of a current position of the vehicle, and
• at least one road dataset determination unit that has at least one assigned vehicle sensor and is designed to output vehicle road datasets that are representative of a position-dependent road-related property,
• the method comprising:
• receiving a database road dataset by the communication interface, said database road dataset supposedly being provided by the database arranged externally to the vehicle and said database road dataset being representative of the position-dependent road-related property, and
• using the database road dataset and a vehicle road dataset to be positionally assigned to said database road dataset as a basis for ascertaining a confidence index that is representative of how high a level of confidence in at least one further database road dataset relating to predefinable positions of the vehicle is.
