Many vehicles are equipped with adaptive headlights that adjust the light beam to the geometry of the roadway so that, when the driver goes into a curve, the light beam smoothly bends to light up the roadway rather than the roadside that lies ahead. Although I guess there is a direct relationship between the angle turned by the steering wheel and the angle turned by the headlight beam, I ignore whether the speed is another input in the "turn function". Any documentation to provide insight on this issue is welcome.
Many thanks
This is a great question!

First of all, thank you for those valuable documents. They were essential to complete my review on adaptive headlight techniques.
The second one actually provided valuable information about the mechanisms that govern headlight swiveling. However, I was looking for a concrete mathematical expression linking the yaw, the steering wheel angle or the speed to the headlight swivel angle.
I guess this is subject to carmakers confidentiality.
