Abstract:
Regulation and certification requirements generally fall into 2 categories: self-certification and type approval. Self-certification requirements, currently used in the United States under Federal Motor Vehicle Safety Standards (FMVSS) regulations, must be objective and measurable with clear pass / fail criteria. On the other hand, Type Approval requirements, currently used in Europe under United Nations Economic Commission for Europe (UNECE) regulations, can be more general relying on the mandated 3rd party certification agency to appropriately interpret and apply the requirements based on the design and configuration of a vehicle. The use of a 3rd party is especially helpful when applying regulatory requirements for complex vehicle systems that operate dynamically, changing based on inputs from the surrounding environment. One such system is Adaptive Driving Beam (ADB) headlamps which allow drivers to use high beams continuously during night time driving, even when other vehicles are present. This is enabled by the ADB system dynamically blocking or shadowing light in selected areas of the high beam pattern from projecting towards other road users. The shadows track other vehicles dynamically, positioned using sensors, electronic controllers, and software. ADB systems are allowed in Europe under UNECE regulations but are not specifically included in FMVSS regulations. To regulate ADB under FMVSS, self-certification test specifications and pass/fail requirements needed to be developed. An SAE task force was established to create a self-certification proposal which could be adopted into FMVSS that also harmonizes with the current UNECE requirements. This paper describes the strategies used by the SAE Task Force to develop self-certification requirements for ADB headlamp systems based on the UNECE type approval requirements, the challenges encountered, and how those challenges were addressed.
