ACSF systems in use were brought to market based on exemption approvals in the EU. These systems show a good and safe performance. Approvals according to UN R79/03 would force modifications to currently used systems without any apparent safety benefit. The current formula for the calculation of s_critical does not take the dynamic behaviour of the vehicles into account, therefore requires gaps that under some traffic conditions don’t usually occur. Since there are different ways of addressing the dynamic behaviour of the vehicles with regard to the original formula, this proposal would allow the manufacturer to specify its own formula provided the safety principle is maintained.

Proposal to insert the provision, “This regulation is without prejudice to national or regional regulations dealing with the development and replacement of parts and systems, physical and digital, with regards to ensure their compatibility with cybersecurity.”

Proposal by IWG ALKS for new regulation for the approval of on-highway automated lane keeping systems operating at speeds below 60 kph reflecting ongoing discussions and agreed points from the initial review during the fifth GRVA session.

Proposal complementary to GRVA/2020/12 to adapt provisions to steering-by-wire and related new technologies with regard to steering angles and system responsiveness.

Proposal to allow ACSF-B lateral acceleration above the maximum limit value in cases where the lane position cannot be maintained by the vehicle (for example, on a tightening curve).

Draft text for a new UN Regulation on the approval of low-speed, on-highway automated lane-keeping systems. This draft will be the basis for discussions at the 6th GRVA session.

Proposal to clarify conditions for automatic deactivation of the direction indicator pursuant to a lane change maneuver.

Summary prepared by the GRVA secretariat of the working party’s activities and programs, including its “top three priorities” for 2021.

Proposal from the AEBS informal group to improve the assessment of AEBS robustness, to delete the clause “for subject vehicle and target vehicle”, and add a reference to paragraph 5.2.1.4. in paragraph 6.10.2.

Draft text for a new UN Regulation on the certification of cybersecurity management systems and the approval of vehicles with regarding to cybersecurity. This draft will be considered during the 6th GRVA session.

Presentation on the safety benefit of automated emergency steering in case of confirmed driver inability to perform the driving task.

Proposal to clarify that the AEBS may be automatically deactivated in the event that the electronic stability control system is deactivated.

Proposal for an “Appendix on Traffic Disturbance Critical Scenarios to the Annex on audit/assessment to the new UN Regulation on Automated Lane Keeping systems (ALKS)” applying concepts under consideration by the VMAD informal group to establish performance criteria based on “driver model” responses to traffic scenarios.
