Abstract:
With the advancement in vehicle technology over the years, many intuitive technologies are coming in automotive passenger vehicles to improve the safety aspects during vehicle driving in night conditions. In addition to headlamps, cornering lamps or infrared camera with head up display etc. are evolving as a part of AFS (Advanced Front Lighting Systems) to aid driver vision. Many OEMs are following conventional methodology of subjective assessments with the ratings on different numerical scale mapped with customer acceptance to validate head lamps and its tech updates. These methods lag in getting repeatability of results, acceptance reliability and not knowing the limitations of the installed system due to high dependency on the selected evaluators.This paper emphasizes on robust test methodology development to validate the complete performance of cornering lamps with the objective test data analysis. It also covers the test set up to be made exclusively to conduct test even in day light. To derive test methodology and finalizing the applicable vehicle parameters, studies were conducted on available test standards, customer usage patterns, and real world road profiles. This methodology provides a way to compare the different technological strategies employed to control the cornering lamps and correlation to subjective assessment.
