DVN : What technology of automatic aiming could solve the tolerance problem?
Michael Hamm [of Audi]: In this case a possible correct answer would be rocket science. No joke—in missiles there are precise 3D positioning devices; we should think on something similar adopted in automotive. A kind of triple gyroscopic determination of the headlamp coördinate system, the car coordinate system, and the street coördinate system. Then we would have perfect aim everytime and everywhere.
DVN: OK, but that would surely take a long time to perfect In the meantime?
M.H.: We must continue in small steps. Improve awareness, improve aiming. We should try to increase automatic levelling to reduce glare and increase ADB systems penetration because they are less influenced by vertical aiming deviations. Wherever possible, decrease tolerances and improve sensor ability. A very big milestone would be any kind of closed loop between the aiming and the resulting light distribution on the street. This is an important task, also for future digital projections on the road.
