Automatic Emergency Braking will become a standard feature in light duty vehicles beginning in 2023 due to a voluntary agreement between vehicle manufacturers, NHTSA, and IIHS. The agreed performance criteria will result in a system that reduces the incidence of low-speed crashes and will likely have little effect on severe injuries and fatalities. Opportunities for fatality reduction associated with automatic braking are significant and are based on implementation approaches. Potential fatality reductions resulting from automatic braking activation thresholds in various crash modes and closing speed ranges were considered. The effects of alternative performance requirements on potential fatality reductions were then examined.
