Adaptive Driving Beam with LED - Beam pattern expectations Vanesa Sanchez, Benoit Reiss - Valeo LighAdaptiveDrivingBeamfunctionbringsalotofbenefitstothedriversinceheorshehasthefeelingofdrivingmostofthetimeinhighbeamwithoutdisturbingotherroadusers.Ithasbeen seen first with Xenon solutions and now on someprototypes with LED. Using LED to perform this functionality first bringsmuch more flexibility in thelightdistributionwhichincreasestheoverallperformancesofthesystemwhilemaintainingverygoodcomfortforthedriver.Actually,upontheusedsolution,withspecificactuatororwithmultipleLED,thesystemmanagement,includingthelightcontrol unit,willbedifferent.Asaresult,the beam pattern will have different evolutions upon driving conditions. Thispaperdescribes in moredetails the possibilities on the light distribution, their main specificationsand their effects for thedriver upon the type of solution and drivingsituations. |
