Abstract: A method is disclosed for checking detected changes to an environmental model of a digital area map first vehicle with a one or more sensors detects an environmental change from an environmental model of a digital area map. Data are transferred from the first vehicle to a central server, wherein the data include information on the detected environmental change, position data of the detected environmental change, as well as information by means of which the sensor quality of the one or more sensors can be detected. Depending on the sensor quality of the one or more sensors, the central server performs a plausibility check of the detected environmental change using data that are detected by a one or more sensors of an additional vehicle and transferred to the central server.
