First Claim
1. A method of generating and updating a precision road property database comprising driving-relevant objects by a two-step object data processing comprising a first step of object data processing by a vehicle and a second step of object data processing by a server database, the server database storing fourth data sets comprising driving-relevant object data, the driving-relevant object data further comprising at least location information and detailed object-based information about at least one of a road object, a road furniture object, a geographic object or a further object related to driving, the method comprising the steps ofa) a vehicle requesting information about an area of interest or an area from the server database, or the server database triggering a data transfer,b) the server database generating at least one first data set related to the request or trigger from fourth data sets stored in the server database, each first data set comprising driving-relevant object data,c) the server database forwarding the at least one first data set to the vehicle which stores the first data sets in a vehicle database,d) the vehicle collecting at least one ambient data set along at least a specific section of its path and/or at a specific time or time interval and/or at least one specific object by at least one sensor of the vehicle, the ambient data sets relating to at least one of driving-relevant objects, road furniture and geographic objects,e) the vehicle performing the first step of object data processing by evaluating the at least one ambient data sets and generating at least one second data set based on the evaluation result, each second data set comprising driving-relevant object data,f) the vehicle generating third data sets containing differences between the object-based information of the second data sets and the object-based information of the first data sets related to the section of the road or the object-based information of the complete second data sets related to the section of the road,g) the vehicle forwarding the third data sets to the server database,h) the server database storing a selection of the third data sets of a plurality of path sections at least partially overlapping each other,i) the server database generating at least one group of objects in each path section by grouping selected objects together and matching the location information with the location information of groups comprising the same objects of other data sets and/or matching the path sections by aligning the groups of objects between the path sections,j) the server database performing the second step of object data processing comprising at least statistical evaluation and post processing of the third and fourth data sets by the server database, andk) the server database updating of the fourth data sets in the server database based on the third data sets.

Abstract
A method and a system of a two-step object data processing by a vehicle and a database for generating and updating a digital road description database containing object-based information about road objects is disclosed. First, the server database comprises fourth data sets and generates and forwards first data sets to the vehicle, which are related to the area of interest of the vehicle. The vehicle is collecting a plurality of ambient data sets at least along a specific section of its path. It is performing the first step of object data processing by evaluating a selection of the plurality of ambient data sets and generating at least one second data set comprising at least location information and detailed object-based information. It further generates third data sets containing differences between the object-based information of the second data sets and the object-based information of the first data sets and forwards the third data sets to the server database. The server database performs the second step of object data processing comprising at least statistical evaluation and post processing to update the fourth data sets in the server database based on the third data sets.

1. A method of generating and updating a precision road property database comprising driving-relevant objects by a two-step object data processing comprising a first step of object data processing by a vehicle and a second step of object data processing by a server database, the server database storing fourth data sets comprising driving-relevant object data, the driving-relevant object data further comprising at least location information and detailed object-based information about at least one of a road object, a road furniture object, a geographic object or a further object related to driving, the method comprising the steps of
a) a vehicle requesting information about an area of interest or an area from the server database, or the server database triggering a data transfer, b) the server database generating at least one first data set related to the request or trigger from fourth data sets stored in the server database, each first data set comprising driving-relevant object data, c) the server database forwarding the at least one first data set to the vehicle which stores the first data sets in a vehicle database, d) the vehicle collecting at least one ambient data set along at least a specific section of its path and/or at a specific time or time interval and/or at least one specific object by at least one sensor of the vehicle, the ambient data sets relating to at least one of driving-relevant objects, road furniture and geographic objects, e) the vehicle performing the first step of object data processing by evaluating the at least one ambient data sets and generating at least one second data set based on the evaluation result, each second data set comprising driving-relevant object data, f) the vehicle generating third data sets containing differences between the object-based information of the second data sets and the object-based information of the first data sets related to the section of the road or the object-based information of the complete second data sets related to the section of the road, g) the vehicle forwarding the third data sets to the server database, h) the server database storing a selection of the third data sets of a plurality of path sections at least partially overlapping each other, i) the server database generating at least one group of objects in each path section by grouping selected objects together and matching the location information with the location information of groups comprising the same objects of other data sets and/or matching the path sections by aligning the groups of objects between the path sections, j) the server database performing the second step of object data processing comprising at least statistical evaluation and post processing of the third and fourth data sets by the server database, and k) the server database updating of the fourth data sets in the server database based on the third data sets.

11. A server database storing fourth data sets comprising driving-relevant object data, the driving-relevant object data further comprising at least location information and detailed object-based information about at least one of a road object, a road furniture object, a geographic object, or a further object related to driving
the server database having means for generating first data sets from the fourth data sets, the first data sets being subsets of the fourth data sets, further corresponding to specific section of a vehicle'"'"'s path and/or at a specific time or time interval and/or at least one specific object and having further means for forwarding the first data sets to the vehicle, each first data set comprising driving-relevant object data, the server database having further means for receiving and storing of third data sets of a plurality of path sections at least partially overlapping each other from a plurality of vehicles, the third data sets containing differences between second data sets having object-based information collected by respective vehicles and the object-based information of the first data sets, the server database generating at least one group of objects in each path section by grouping selected objects together and matching the location information with the location information of groups comprising the same objects of other data sets and/or matching the path sections by aligning the groups of objects between the path sections, the server database having means for statistical evaluation and post processing of the third and fourth data sets and for updating the fourth data sets by using the results thereof.
