Solution Overview

Problem

Existing methods for creating test scenarios for virtual testing of automated driving functions require high-dimensional configuration and result in high arithmetic effort, making it difficult to identify relevant parameter combinations that significantly influence target variables.

Innovation Solution

A computer-implemented procedure for criteria-based creation of a virtual test configuration that defines dependencies between configuration parameters and target variables, determines test algorithms and parameter intervals, and sets application conditions to focus on parameter combinations with significant influence on target variables.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If full-dimensional parameterization of logical scenarios is used to best cover the parameter space, then the coverage of parameter space is improved, but the computational effort increases significantly

Engineering Contradiction:
Improveparameter space coverageVSAvoidcomputational effort
Core Design Contradiction:
Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent segments the monolithic ITC configuration into multiple partial ITC configurations, each handling a subset of parameter variations. This division allows the parameter space to be covered comprehensively while reducing the computational burden on any single configuration, as each partial configuration processes only a portion of the total parameter combinations.

Inventive Principle:
Principle #1Segmentation

2Reliability

If the configuration step requires users to define all relevant parameters and KPIs manually, then the completeness of test configuration is improved, but the complexity of the configuration process increases

Engineering Contradiction:
Improvecompleteness of test configurationVSAvoidconfiguration process complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The system automatically generates partial ITC configurations based on predefined templates and available test data, reducing the manual effort required from users. The configuration process performs self-service by automatically identifying relevant parameters, setting appropriate KPIs, and creating multiple partial configurations without requiring exhaustive manual specification by the user.

Inventive Principle:
Principle #25Self-service

3Adaptability or versatility

If traditional ITC methods are used without criteria-based filtering, then all parameter variations are tested, but the difficulty of evaluating results increases

Engineering Contradiction:
Improveparameter variation coverageVSAvoidresult evaluation difficulty
Core Design Contradiction:
Adaptability or versatilityVSDifficulty of detecting and measuring

Solution Approach 1:

The patent extracts and isolates specific parameter combinations that have a defined influence on target variables by applying criteria-based filtering. This extraction process separates relevant parameter variations from the complete parameter space, allowing focused evaluation on only those combinations that matter for the automated driving function being tested, thereby reducing result evaluation difficulty.

Inventive Principle:
Principle #2Taking out (Extraction)
