Abstract：According to Chinese national standards and CIE standard,this study established a Unified Glare Rating(UGR)classification system for automotive cabin lighting,with a comfort threshold of UGR≤19.Five luxury vehicle models currently sold in the Chinese market were selected.Through actual measurement of cabin lighting parameters,it was found that darker cabin colors correspond to higher UGR values.Analysis revealed that cabin surface reflectance and solid angles are critical factors influencing the UGR.By optimizing UGR through key strategies,a dynamic glare control model for automotive cabin lighting was developed.
