Abstract
A method, a processing unit which carries out the method, and a system including the processing unit for updating a digital map for locating motor vehicles are provided. In the case of the method for updating a digital map for locating motor vehicles, surroundings information is detected by a vehicle for the purpose of updating the digital map and the detected surroundings information is compared to the surroundings information which is stored on the digital map. In this case, the vehicle is located on the digital map, which means that the location or position of the vehicle on the digital map is known. For the purpose of detecting the surroundings information, the vehicle is navigated along a first route, whose most recently carried out comparison of surroundings information dates back the longest as compared to at least one further optional route.
