A method and a system for generating and updating a digital road description database containing object-based information about at least one of a road object, a road furniture object and a geographic object is disclosed. A vehicle is collecting ambient data like images along multiple sections of its path, generating third data sets comprising at least location information and detailed object-based information. The third data sets are forwarded to a server database. The database identifies common groups of object reference points in multiple vehicle path sections and generates alignment functions for matching and/or aligning the at least one group of object reference points in at least two of the vehicle path sections relating to the same part of the road. The same alignment function is applied to all other third data sets of the same vehicle path section. The database updates the fourth data sets in the database based on processing the third data sets.

System and method of matching of road data objects for generating and updating a precision road database

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.

A method for checking a total distance travelled by a motor vehicle and displaying the total distance in the motor vehicle includes: detecting a change in a component of a control device of the motor vehicle, change in the component being irreversible and taking place over a time period; assigning the magnitude and/or type of the change in the component to a comparison distance, related to the time period, travelled by the motor vehicle; comparing a distance detected by an odometer of the motor vehicle during the time period with the comparison distance; and an operator of the motor vehicle retrieving a result of the comparison or the operator receiving an automatic transmission of the result of the comparison.
