The previous session report was approved with a note on post-crash recording intervals. A DSSAD Guidance Document feedback deadline was set for month-end. Phase 2 discussions on near-miss events require clarification of concepts and their safety contributions. For EDR Step 2, a 10 Hz sampling rate was adopted over 2 Hz following opposition from industry regarding implementation burden and support from regulatory bodies for accident reconstruction needs. Outstanding discussion items will be consolidated into a working document. Terms of Reference discussions on maintaining current structure versus integrating DSSAD into the ADS Informal Working Group will continue. The May 12 meeting was rescheduled due to conflict with ESV Toronto.

The EDR-DSSAD informal group approved definitions for detected objects and recording parameters, established language for power and communication failures, and agreed to a -2.5-second to 300-millisecond recording interval for rollover events. Discussions on fire-resistant data storage and automated emergency braking recording intervals remain unresolved. The group deferred decisions on EDR requirements for automated driving systems pending further analysis of overlap with DSSAD regulations.

Proposal concerning “detected objects” and data element precision for the ADS regulation provisions on DSSAD.
