As automotive software becomes more sophisticated, extensive evaluation and validation to ensure the safety and performance of related products have emerged as critical processes, alongside global R&D competition in autonomous driving and advanced driver assistance system (ADAS) technologies. Global auto makers are increasingly requiring suppliers to provide large-scale, data-driven validation, often involving tens of thousands of hours of testing, before approving core components for use in software-defined vehicles (SDVs).
Hyundai Mobis has established a data integration management solution that it says significantly shortens this process, enabling the company to secure a competitive edge in the global market.
The evaluation and validation system can repeatedly test electronic control units (ECUs) for SDVs and autonomous driving by linking data from actual road tests with data management solutions and simulators to replicate various driving scenarios.
This system can reportedly reduce evaluation and validation time through a platform that connects multiple simulators in parallel, reflecting various validation scenarios. Hyundai Mobis plans to expand this platform to connect up to 60 such simulators. This, the company says, will enable it to perform 10,000 hours’ worth of evaluation and validation in one week.
The system is based on data collected under various conditions in real-world driving and parking environments via sensors mounted on test vehicles. A key advantage is its ability to replicate scenarios that are difficult to reproduce in reality, such as nighttime driving, rainy conditions and unexpected incidents, by integrating them with simulations in a virtual environment. By combining real-world and virtual data in an optimal ratio, the company expects to evaluate the recognition performance and stability of autonomous driving and ADAS systems.
Hyundai Mobis plans to use this system to validate the performance and reliability of algorithms for autonomous driving sensors such as radar, cameras, lidar and ultrasonic sensors, as well as various ECUs. By establishing an evaluation and validation system capable of managing large-scale sensor data in a one-stop manner, the company expects to strengthen its technological competitiveness for SDV advances, thereby gaining momentum for more aggressive global order acquisition activities.
“In the era of SDVs and autonomous driving, evaluation and validation are just as critical as technology development. We expect that establishing this evaluation and validation system will simultaneously expand the speed and scope of validation, thereby significantly boosting our competitiveness in securing orders for core SDV components,” explained Ko Bongchul, chief of automotive electronics R&D at Hyundai Mobis.
