Proposal to clarify that UN R140 does not mandate the installation of electronic stability control systems (ESC) on vehicles but rather specifies requirements for the approval of vehicles should they be equipped with an ESC system.

Document prepared by Japan and the European Commission on behalf of the Informal Working Group on Advanced Emergency Braking System (AEBS). It provides the status of the proposed regulation through November 2018 in order to provide a basis for review and discussion during the January 2019 GRVA session.

Proposal to clarify the assessments to be conducted by a technical service for complex electronic systems, particularly with regard to advanced driver assistance systems. The proposal includes a new definition to ensure the assessment includes system response to changes in the ambient and/or operating conditions, provisions to ensure that any disabled functions intended for use on a production vehicle are declared and assessed, and a footnote to clarify that the assessment must be reviewed and signed by the same type approval authority as the one responsible for issuing the approval to UN R79.

Proposal to introduce provisions for the approval of Remote Control Manoeuvring (RCM) systems.

Proposal, based on document GRRF-86-13, to resolve measurement concerns in the test requirements for ACSF of Category B1 and C. The proposal addresses issues identified in Annex 8, improves reproducibility and robustness of the procedures, fills in gaps in the test cases, and provides additional details on measuring equipment and test execution.

Proposal to clarify requirements of the optical signal for a CSF intervention to ensure sufficient flashing tell-tale visibility for the driver, to specify the duration of such ACSF signals, to ensure a safe hierarchy of signals (e.g., ESF over CSF) by priority, to clarify that deactivation when departing an ODD means the “off mode”, and to add a cross-reference pointing to paragraphs that define cases of manual and automatic deactivation.

Proposal to align the provisions of UN R90 related to approval numbers and markings with the provisions of Schedule 4 to the 1958 Agreement.

Proposal to clarify that UN R139 does not mandate the installation of brake assist systems (BAS) on vehicles but rather specifies requirements for the approval of vehicles should they be equipped with a BAS system.

Proposal to introduce provisions relevant to the activation of stop lamps under more conditions than application of the service brake only, e.g. also by regenerative braking.

Proposal of maximum relative impact speeds under the proposed test scenarios.

Proposal for the draft regulation on automated lane-keeping systems address the following sections:
2.6. Driver Availability Recognition
2.7. Transition Demand and System Operation during Transition phase
2.8. Information to the driver
2.9. Minimal Risk Manoeuvre
2.10. Emergency Manoeuvre

Proposal of amendments from the AEBS informal group to their original submission for a new UN Regulation.
