Nowadays, intelligent illumination camera driven systems represent the state of art for head lighting, as the NGHB – non glaring high beam, implemented by different technological solutions as the ADB – adaptive driving beam, the matrix beam, pixel lighting. Other functions as the "Marking Light" are also camera driven.

During the development of such functions the car maker and the supplier must tune the proper transitions, dynamical and static behaviors, transients, etc., to optimize the full system. Those adjustments, made up with prototypes, are typically very time consuming. For functions as the matrix beam, the choice of the number and width of segments can even require many prototypes and drivers.

We have developed a new strategy for implementing in a driving simulator a camera model and algorithms to allow the tuning of such complex lighting functions. The meta states or partial positions of the illumination devices are stored as input data. Moreover, the optimization loops and setup can be transferred to the real illumination device drivers and controllers.

Concrete examples will be presented to demonstrate some of the optimization and model strategies.
