Proposal to amend UN R169 by inserting definitions for non-volatile and volatile memory, and modifying the Last Stop trigger criteria. The amendment allows threshold criterion (a) data to be written to volatile memory only, transferring to non-volatile memory when other triggers occur or the master control switch deactivates. This reduces memory wear in vehicles with frequent stops exceeding 20 seconds.
Proposal to introduce provisions for rollover protection systems, advanced emergency braking systems, vulnerable road user secondary safety systems, and driver assistance systems. Amendments clarify triggering conditions for event recording and data locking, expand data elements to capture vulnerable road user collisions and advanced safety system interventions, increase sample rates for improved data granularity, and add transitional provisions for type-approval acceptance timelines.
In compliance with Rule 37 of the Rules of Procedure (TRANS/WP.29/690 and Amends.1 and 2), GRSG will elect the Chair and Vice-Chair of the sessions scheduled for the year 2020.
