Simulation software enables virtual testing of headlight systems

November 13, 2017 // By Christoph Hammerschmidt
With its VRX 2018 driving simulator, virtual prototyping expert Optis (La Farlèdere, France) covers the behaviour of state-of-the-art lighting systems, including the AFS and ADB matrix beams as well as the pixel beam. An updated version introduced recently includes a new feature set specifically for OEMs, including testing and validation for pixel headlamps, adjustment of headlamp control logic. It also enables the virtual evaluation of IIHS (Insurance Institute for Highway Safety) tests.

As headlights become more sophisticated, the complexity involved in their development requires more intense testing, necessitating several physical prototypes, in engineering departments and on test tracks, to fine tune the final product’s lighting capabilities. Testing these systems on several iterations of a prototype can be expensive and potentially dangerous on real-world tracks. To combat these factors, Optis’ virtual solution allows automotive OEMs and their tier-1 suppliers to test and experience the performance of their headlights with virtual prototypes on virtual test tracks, recreating realistic traffic conditions, including weather, incoming cars and pedestrians.

New product features allow for the adjustment of the control logic of the headlights to improve both visibility and perceived quality. Adjustments include maximizing the quantity of light on the road, while avoiding glare on oncoming cars, as well as a relevant driver assistance that facilitates communication with road users. These fine-tuning solutions ensure added comfort for customers and improved safety while driving at night.

The simulator allows testing dangerous scenarios without risks. In its latest version, it introduces the assessment of headlight systems against IIHS standards. It is enables design engineers to optimize lighting systems and control the settings and programming of the virtual prototype, which will increase the future score of the IIHS rating due to an accurate and complete analysis against IIHS criteria, which is considered as one of the most influential auto ratings.
