Embodiment Construction

[0019] figure 1 An exemplary sequence of a computer-implemented method for providing a digital road map and its use for simulation testing of vehicle systems is shown schematically.

[0020] In a first step 101 , a randomly selected and optionally predetermined representation 12 for a selected property is extracted from a database 11 in which permissible representations of this property are stored for a specific road property.

[0021] In this case, the database includes the assignment of road properties and the permissible representations for said road properties, wherein the representations are defined in such a way that they are mutually exclusive, ie there are no overlapping. The database includes in particular Zwicky boxes (Zwicky-Boxen), morphological boxes (morphologische Kasten) or comparable data structures for combinatorial modeling (kompositionale Modellierung) that combinatorially uses dimensions and alternatives within the individual dimensions Describe the rele...

Abstract

A computer-implemented method for providing a digital road map for testing an at least partially automated vehicle system. the method includes: accessing a database in which are stored permissible characteristics of the road properties for a multitude of road properties; creating at least one road map section by one of the possible characteristics being selected for the road map section for the first of the multitude of road properties, in each particular case in automated fashion from the database; providing the digital road map, the digital road map including the at least one road map section.

Description

technical field [0001] The invention relates to a computer-implemented method for providing a digital road map, the digital road map being used in particular for testing at least semi-automated vehicle systems. Background technique [0002] Automated vehicle systems must be designed for many different situations. The security of such systems constitutes a large technical challenge. Due to the infinite range of possible driving situations, corresponding tests based on safety requirements are extremely complex and almost impossible to describe solely by actual tests. Proper support for testing through mocking is desirable. In such simulations, a particular challenge is to ensure as wide a coverage as possible and in the best case quantifiable coverage of possible situations. [0003] Road maps for the simulated testing of vehicle systems are created by first measuring real roads with highly precise sensor systems and then manually digitally reprocessing the measurement data...
