VERIFICATION UNIT FOR HEADLIGHTPARAMETERS BASED ON EMBEDDEDSYSTEM

[摘要] Continuous innovations in automotive lighting technology pose the problem of how to assess new headlights systems. For car manufacturers, assessment is mostly relative. Given a headlights system to be tested how does it compare with another, maybe from a different supplier, in terms of features such as light intensity, voltage, current and power rating. This comparison is best performed dynamically, asking experts actually to drive along a certain testing track to write down later the visual impressions that they remember. Our paper includes the testing of physical parameters of headlights like current, intensity and voltage.
