Device and method for associating new data with a digital map

A method for associating new data with a digital map which is available in a vehicle, comprising:

• receiving, by a vehicle-to-vehicle communication and/or a vehicle-to-infrastructure communication (C2X) receiver of a vehicle device, at least one new data value corresponding to a position of a vehicle, from a C2X transmitter of another vehicle or of an infrastructure device;
• comparing, by a computation device of the vehicle device, the position of the vehicle with existing data values corresponding to a position profile of an existing roadway of a digital map stored in a memory device of the vehicle device;
• adding, by the computation device, a new roadway to the digital map when the position of the vehicle does not correspond to the position profile of the existing roadway of the digital map stored in the memory device;
• updating, by the computation device, the position profile of the existing roadway of the digital map stored in the memory device with new data values indicating a new position profile of the existing roadway of the digital map stored in the memory device and updating a timestamp of the new data values, in response to the computation device determining, based on the position of the vehicle traveling on the existing roadway, that the position profile of the existing roadway of the digital map stored in the memory device has changed;
• maintaining, by the computation device, the position profile of the existing roadway of the digital map stored in the memory device and updating a timestamp of the existing data values in response to the computation device determining, based on the position of the vehicle traveling on the existing roadway, that the position profile of the existing roadway of the digital map stored in the memory device has not changed;
• transmitting, by the computation device, at least one of the new roadway, the updated position profile of the existing roadway and the timestamp to at least one of a driver assistance system of the vehicle and a driver safety system of the vehicle;
• and
• using, by the computation device, a result of the comparison as a basis for an assessment of the existing data values from the digital map and/or the new data value,
• wherein the assessment of one or more data values from a portion of the digital map includes a reliability estimation for the data values which is stored for the respective data value or the respective portion of the digital map.
