Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual data analytics methods are used for validating ADAS systems, then measurement precision can be maintained, but productivity is significantly reduced and loss of time increases
Solution Approach 1:
The patent introduces automated analytics tools and cloud-based processing platforms as intermediaries between raw sensor data and validation results. These intermediary systems handle the computationally intensive statistical analysis and KPI calculation, freeing human operators from manual data processing while maintaining validation accuracy through standardized algorithms and automated comparison against regulatory requirements.
Solution Approach 2:
The patent replaces manual mechanical data analysis processes with automated computational systems. Statistical analysis, performance metric calculation, and compliance verification are performed automatically using software algorithms rather than human analysts, dramatically increasing productivity while maintaining or improving measurement precision through consistent, repeatable analysis methods.
2Reliability
If extensive manual data analytics are performed, then analysis depth can be maintained, but loss of time and resources increase significantly
Solution Approach 1:
The patent implements preliminary automated data processing and pre-computation of statistical metrics before full validation analysis. Cloud-based platforms pre-process sensor data, calculate baseline performance indicators, and prepare datasets for analysis, reducing the time required for actual validation while maintaining reliability through systematic, standardized procedures that eliminate human error and inconsistency.
3Productivity
If automated processing is implemented, then productivity increases, but device complexity increases
Solution Approach 1:
The patent employs universal cloud-based processing platforms that can handle multiple types of sensor data (camera, radar, LIDAR) and perform various analytics functions through a single integrated system. This multi-functional approach increases productivity by consolidating processing capabilities while managing complexity through standardized interfaces and unified data pipelines rather than separate specialized systems for each function.
Data Source
AI summary
A method for testing a vehicular driver assistance system includes recording sensor data from a sensor of a vehicle equipped with the vehicular driver assistance system and annotating the recorded sensor data. The annotations represent a predicted output of a processor when processing the recorded sensor data for the vehicular driver assistance system. The recorded sensor data and the annotated sensor data are stored at data storage. Analysis data is generated based on statistical analysis of the recorded sensor data and the statistical analysis of the annotated sensor data. The analysis data is stored at a results database. A key performance indicator (KPI) report is generated using the analysis data. The KPI report includes a dynamic graphic representation based on the analysis data.
