Aptiv Implements Virtual Scenarios for ADAS Validation

Aptiv is a global automotive leader that is working to solve the industry’s biggest mobility challenges through autonomous driving and software-defined vehicle technology. Conducting on-road, sensor-based advanced driver assistance systems (ADAS) ECU tests is both time-consuming and expensive, so Aptiv uses simulations and digital twin technology to evaluate its designs. 

ASAM OSI^® (Open Simulation Interface) is the base of Aptiv’s architecture, and MathWorks supports various ASAM OpenX^® standards, including OpenDRIVE^®, OpenCRG^®, and OpenSCENARIO^® DSL. Furthermore, integrating RoadRunner into Aptiv’s workflow enabled the creation of multiple virtual scenarios by allowing designers to use features such as HD map imports, GIS data handling, and exports to various other environmental simulators via OSI export. 

The Aptiv architecture is built on OSI-based sensor and logic models. RoadRunner provided plug-and-play functionality through ASAM^® open simulation interface export. The sensor model used these ASAM OSI traces to detect objects virtually and the recorded sensor data was then fed into the logic model, which used tracking filters to generate warnings and alerts.
