“Placeholder” document introducing draft new requirements under the EDR Step 2 workstream. The document defines non-volatile memory for permanent EDR data storage and volatile memory for temporary data buffering. Requirements specify that EDRs capture and record data to non-volatile memory when triggers occur, with capacity for at least five events. Triggers include sudden deceleration exceeding 3.25 m/s² for 0.7 seconds, vehicle stops at 0 km/h for 20 seconds, and safety system activation. The amendment allows certain stop events to be written to volatile memory only, transferring to non-volatile memory when other triggers occur or the master control switch deactivates, reducing memory wear in vehicles with frequent stops.

Proposal from the EDR/DSSAD informal group pursuant to the work of the GRSG task force on Automated Vehicles Regulation Screening to enable application of UN R169 to ADS vehicles.
