This regulation establishes uniform approval provisions for Advanced Emergency Braking Systems (AEBS) fitted to motor vehicles of categories M1 and N1. The AEBS shall automatically detect imminent forward collisions with vehicles, pedestrians, or bicycles, provide driver warning, and activate vehicle braking to avoid or mitigate collision severity. The system must meet specified performance requirements under defined test conditions for car-to-car, car-to-pedestrian, and car-to-bicycle scenarios. Requirements include collision warning provision, emergency braking of at least 5.0 m/s², active speed ranges, driver interruption capability, deactivation controls, and warning indications. Testing procedures, vehicle conditions, target specifications, and virtual testing provisions are specified.
Document confirms homework points for consideration of night-time requirements for car-to-pedestrian scenarios in UN R152. Topics include vehicle categories M1 and N1, crossing and longitudinal collision types, farside/nearside pedestrian direction, pedestrian walking speed of 5 km/h, lighting conditions, collision points at 25%, 50%, and 75%, dummy types, vehicle activation speeds of 30–60 km/h without obstruction and 40–50 km/h with obstruction, and speed reduction. Daytime requirements discussion covers car-to-car speed reduction at 80 km/h, collision point revision, and car-to-pedestrian speed reduction review based on current technology.
Terms of Reference and Rules of Procedure for the Informal Working Group on Prioritization (IWG-Prio). The IWG-Prio shall develop recommendations on prioritization criteria including regulatory urgency, safety, environmental, fuel efficiency and security benefits, resource implications, field data availability, technology maturity, and alignment with ITC and WP.29 strategies. The group shall conduct a high-level review of ongoing and proposed activities and develop recommendations regarding initiation and continuation of regulatory activities. The IWG-Prio shall identify opportunities to improve efficiency of WP.29 activities including coordination among groups, meeting scheduling, digitalization, information sharing, and establishment, continuation, review and closure of working groups and task forces. The group shall prepare recommendations for consideration by AC.2 and WP.29 at their November 2028 session.
