Performance Assessment of Vehicle Headlamps

A joint CIE technical committee (TC4-45) and GTB Front Lighting Working Group activity was established in August 2005 as a continuation of the GTB taskforce that had been working for two years with the objective of developing a headlamp performance rating system to be used by EuroNCAP. When EuroNCAP decided not to continue to introduce a headlamp rating system the work undertaken by GTB was transferred into the CIE structure with a view to completing the study, publishing the conclusions and establishing a technical standard. During the GTB activity a total of 48 organizations from the GTB global national delegations had contributed and 18 meetings had been held between August 2003 and April 2005. A weeklong testing event had taken place in Spain in May 2005 with the successful validation of a number of the performance parameters but further work was indicated with regard to the algorithms for the assessment of range and glare. Since its formation, the joint CIE TC4-45/GTB Technical Committee has continued to work on the refinement of the assessment of the assessment of range and glare. A second validation test event took place in Germany in March 2006 and this contributed to a revised algorithm for the calculation of passing beam and driving beam range. A test event to concentrate on the validation of the glare assessment algorithms took place in February 2007 and a further event will take place to validate the range calculations in Italy in May. This paper, presenting the status of the work of the TC4-45 overviews the assessment method being developed and provides a summary of the results of the validation testing so far completed. The full procedure and the algorithms to be used will be contained in the CIE report and consequently it is not possible to provide the detail in this paper. The objective is to complete the work and develop a CIE technical report and draft standard by the end of 2008.
