FMVSS 108 Testing for Adaptive Driving Beams | Technical Webinar

Explore the test scenarios, instrumentation, boundary conditions, and validation methodology used to navigate the challenges of the newly implemented FMVSS 108 Adaptive Driving Beam requirements and the complex testing needed to demonstrate compliance

Adaptive Driving Beam systems continuously adjust headlamp output to improve visibility while limiting glare for oncoming drivers or pedestrians. Unlike traditional static lighting evaluations, FMVSS 108 assesses this performance under dynamic conditions as the test vehicle, stimulus vehicle, beam pattern, and operating conditions change.

Testing requires precise control of vehicle speed, position, pitch, road geometry, detector placement, and photometric measurements. With eight prescribed scenarios and numerous allowable combinations of speed, curve radius, and measurement distance, developing a repeatable validation program can be a significant engineering challenge.

Join Intertek experts for a technical webinar examining how FMVSS 108 ADB testing is planned, instrumented, executed, and evaluated at the Arizona Mobility Test Center. The presentation will explore stimulus fixture geometry, synchronized vehicle and illuminance measurements, boundary condition selection, run acceptance criteria, and the investigation of unexpected results.

What the Technical Session Will Cover

• Translating the eight FMVSS 108 ADB scenarios and prescribed stimulus geometries into a practical track validation plan
• Capturing and synchronizing vehicle dynamics and illuminance data using GNSS, inertial measurement systems, and photometric detectors
• Selecting representative boundary conditions across permitted vehicle speeds, curve radii, and measurement distances
• Controlling vehicle speed, lane position, test path, curve radius, and pitch while evaluating results against run acceptance criteria
• Applying a repeatable validation methodology incorporating more than 200 runs to assess performance and investigate unexpected results
• And more!
