Starting from 7 July 2024, new regulations concerning active safety features in vehicles, such as speed limiters, entered force in the European Union. The New-Vehicle General Safety Regulation (GSR2) revises the minimum performance standards for type-approval of motor vehicles in the EU, mandating the implementation of certain advanced driver assistance systems: intelligent speed assist (ISA), autonomous emergency braking (AEB), driver drowsiness and attention warning (DDAW), and emergency lane-keeping systems (ELKS).
GSR2’s implementation phases are:
- July 2022: New technical requirements for new vehicle models.
- July 2024: New units of existing vehicle models must include ISA, AEB, DDAW, and ELKS.
- July 2026: Inclusion of advanced driver distraction warning (ADDW) and extra pedestrian and cyclist AEB.
ISA detects traffic signs and issues a speed limit warning via a camera and map data. AEB uses sensors (camera, radar, lidar) to cut collision rates—50 per cent for rear-end and 30 per cent for pedestrian collisions.
ELKS keeps vehicles in their lanes using corrective steering, using sensors like cameras for lane detection, or potentially lidar for lane and obstacle detection.
Other new features required by GSR2 include AIIF (Alcohol Interlock Installation Facilitation), EDR (Event Data Recorder), ESS (Emergency Stop Signal), RD (Reversing Detection system), and TPMS (Tire Pressure Monitoring System).
