A method of generating digital driving-relevant object data sets by using data collected by at least one vehicle when traveling along a path on a road, for updating a server database, the server database storing data sets comprising driving-relevant object data, the driving-relevant object data comprising at least location information, an optional object reference point and detailed object-based information about at least one driving-relevant object like a road object (310, 311), a road furniture object (370, 371, 372), a geographic object or a further object related to driving, the method comprising the steps of forwarding by the server database first data sets to at least one vehicle, wherein the first data sets are based on fourth data sets stored in the server database; a) the at least one vehicle generating at least one ambient data set along sections of the path based on information collected by at least one sensor of the vehicle, the ambient data sets relating to at least one driving-relevant object, b) the at least one vehicle performing object data processing by evaluating the at least one ambient data sets and generating at least one second data set of driving-relevant object data based on the evaluation result, c) the at least one vehicle generating and forwarding at least one third data set related to a respective one of the sections of the vehicle path, which the vehicle decides or has been requested to report, to the server database, the third data sets containing second data sets and/or differences between second data sets and first data sets received by and stored in the vehicle, d) receiving and storing of the at least one third data set by the database, the method being further characterized by the following steps e) the server database identifying, by their related third data sets, a first plurality of vehicle path sections related to a part of the road, the identified path sections at least partially overlapping each other, f) the server database identifying a plurality of object reference points in each vehicle path section, g) the server database generating at least one group of object reference points in at least two of the vehicle path sections of the first plurality of vehicle path sections relating to the same part of the road, each group comprising the same object reference points, and h) the server database generating alignment functions for matching and/or precisely aligning the at least one group of object reference points and/or the related objects in the at least two of the vehicle path sections of the first plurality of vehicle path sections relating to the same part of the road and applying the same alignment functions to all other third data sets of the same at least two vehicle path sections for generating or updating fourth data sets stored in the server database, the fourth data sets containing driving-relevant object data. a) the at least one vehicle generating at least one ambient data set along sections of the path based on information collected by at least one sensor of the vehicle, the ambient data sets relating to at least one driving-relevant object, b) the at least one vehicle performing object data processing by evaluating the at least one ambient data sets and generating at least one second data set of driving-relevant object data based on the evaluation result, c) the at least one vehicle generating and forwarding at least one third data set related to a respective one of the sections of the vehicle path, which the vehicle decides or has been requested to report, to the server database, the third data sets containing second data sets and/or differences between second data sets and first data sets received by and stored in the vehicle, d) receiving and storing of the at least one third data set by the database, the method being further characterized by the following steps e) the server database identifying, by their related third data sets, a first plurality of vehicle path sections related to a part of the road, the identified path sections at least partially overlapping each other, f) the server database identifying a plurality of object reference points in each vehicle path section, g) the server database generating at least one group of object reference points in at least two of the vehicle path sections of the first plurality of vehicle path sections relating to the same part of the road, each group comprising the same object reference points, and h) the server database generating alignment functions for matching and/or precisely aligning the at least one group of object reference points and/or the related objects in the at least two of the vehicle path sections of the first plurality of vehicle path sections relating to the same part of the road and applying the same alignment functions to all other third data sets of the same at least two vehicle path sections for generating or updating fourth data sets stored in the server database, the fourth data sets containing driving-relevant object data.
