Traditional methods often fall short when it comes to efficiency and innovation. Our team launched a powerful solution leveraging Artificial Intelligence (AI) to accelerate and simplify the report analysis in Hil testing processes for ADAS.
Who is the client?
Our client is a major German automotive OEM with complex Hardware-in-the-Loop (HIL) testing requirements, where embedded software and functions for ADAS are validated. They process large volumes of continuous test reports that require meticulous analysis to maintain quality standards.
What was the problem?
The client faced significant challenges with their test analysis workflow. Engineers spent excessive time manually analysing test reports filled with numerical data. These Excel-based methods were time-consuming and error-prone. Identifying patterns across multiple reports was difficult, and the process lacked the sophistication needed to quickly pinpoint issues in specific test areas. So, a key aim of the project was to improve the process and free up time for value-adding tasks.
What was the Expleo solution?
We developed an AI-powered test analysis tool specifically tailored to the client’s testing environment and reporting needs. The solution utilises Microsoft’s OpenAI Large Language Model (LLM) Service hosted in Azure and operates on a cloud-based platform while maintaining strict data security protocols. Our tool enables intuitive interaction with test data through natural language queries, automatically aggregating information from multiple test reports while identifying patterns and anomalies more efficiently than manual methods. The project was developed through close collaboration between our local Expleo team in Germany and our technical implementation specialists in India.
In addition to the technical challenges, the legal aspect was essential. The project team had to ensure that the application complied with the strict requirements of the General Data Protection Regulation (GDPR) and the EU’s AI law. All data remains in a secured cloud environment managed by Expleo, with complete deletion capabilities to ensure compliance.
How did that solution help?
- User Interaction: The AI tool fundamentally transformed how the client interacts with their report data. It enhanced analysis capabilities beyond what conventional tools allow and created a more user-friendly experience through natural language querying. The system allows users to ask questions like requesting all tests from yesterday that had errors in a specific area, rather than just receiving a finished evaluation.
- Time efficiency: Automates the tedious tasks of evaluating passed/failed test cases, drastically reducing analysis time
- Root cause identification: Assist the test engineer to identify the root causes of test failures
- Cross-test run comparison: Seamlessly compares test results across multiple runs to track performance trends.
- AI-driven queries: Uses AI to answer related questions, making analysis intuitive and reducing manual effort
- Data insights: Provides insights into test reports and results, simplifying decision-making and improving testing strategies
What were the results?
Our client experienced a reduction in time spent on routine analysis tasks, along with higher precision in test report evaluation and faster identification of critical issues in testing processes. This efficiency improved the overall quality of analysis with reduced potential for human error and created more time for engineers to focus on value-adding tasks while.
Could it work for me?
Yes. While this solution was customised for automotive HiL–testing of embedded software and systems, the underlying technology and approach are highly adaptable to various industries and testing environments. Any organisation dealing with large volumes of test data, complex analysis requirements, repetitive evaluation processes, and the need for highly advanced user interaction could benefit from a similar AI-powered approach. The cloud-based architecture allows for customisation to meet specific industry needs while maintaining strict data security protocols.
