Description

Applications: headlight studies, tests and benchmarking

• Headlight components and systems development (technology, design, cost optimization)

  

• Intelligent lighting system (AFS) development
• Night-time driving and weather conditions for road safety and comfort
• Impact of headlight system and traffic on driver (glare effects)

Feature specifications 

• Photorealistic rendering (BRDF): advanced shading model for real time 3D reflectance (wet road, snow, road marking…)
• Illumination measurement on ground/wall/traffic via virtual sensors.
• Mechanical data adjustable for each lamp (road height, cross car spacing, driver eye position…)
• Advanced front lighting system benchmarking (AFS analysis tool)
• Generation of user’s own AFS strategy using SDK interfaces

Benefits 

• Reduction of prototyping cost and time-to-market.
• Improvement of the quality of test phase, validation and tuning of light beam properties

Control desk interface

• Interactive real time headlight edition through an intuitive GUI
• Use of lighting strategy library (dll)
• Interactive measurement tools (ground grid, beam pattern, 2D/3D isolux, aiming wall)

Key points

• Open architecture with a powerful SDK (C++ API, RoadXML API, Labview® , Matlab®/ Simulink, HIL)

  

• HDR rendering (High Dynamic Range)

Headlight testing and driving in simulated environment

• Dynamics model
• Traffic model
• Scenario edition
• Customize road network and 3D environment

Photometric data input

• Goniometric data or virtual design data
• Standard photometric file formats: FOTA, IES
• Proprietary photometric file formats (on request)

Performance 

• 30 light sources at 30Hz on a bi-Xeon Quadro FX5600 Windows XP/Vista/Seven
• Field of View: from 60° to 360° (multichannel)
• 3 km virtual roads
