The agenda includes discussion of DSSAD regulatory text guidance, EDR Step 2 proposals comments, and EDR for ADS. The next meeting is scheduled for September 15-17, 2026, as a hybrid event in Europe.
Systems with ACSF B2, D and E functionality cannot be approved to UN R79 unless incorporated within a DCAS complying with UN R171. However, these functionalities may exist independently of DCAS, requiring clear distinction. Where not part of DCAS, this must be specified in the EDR regulation. A new EDR data element, “DCAS status”, could encompass ACSF B2, D and E functionalities. These functionalities are now treated either as individual functions or as components of DCAS.
