The proposal to clarify that enabling the system under the test procedure is only necessary in cases where the system is not already in the enabled state.

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 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).

Establishment of the Executive Committee (AC.3) of the 1998 Agreement Fifty-sixth session (item 12) – Proposals for amendments to UN GTRs (items 14.2.1. to 14.2.4.)

Proposal as approved during the 6th GRVA session for a new UN Regulation on approval requirements for low-speed, on-highway automated lane-keeping systems.

The objective of this proposal is to develop, in the framework of the 1998 Agreement, an amendment to UN Global Technical Regulation (GTR) No. 8 on Electronic Stability Control to amend to the testing provisions to accommodate the latest innovations for steering systems which have significantly low steering gear ratio (i.e. quick steering characteristics).

Proposal to harmonise the requirements of UN R78 with the latest amendments to UN GTR No. 3 adopted by GRVA at its fourth session. Paragraph 5.1.18 aims to clarify with an explicit article that the rider is duly informed when activating a riding mode that disables the ABS on the rear axle.

Proposal to resolve measurement concerns in the test requirements for ACSF of Category B1 and C by introducing provisions for tolerances, including:

1. inclusion of the position at which the lateral acceleration was measured and the position of the centre of gravity of the vehicle for better traceablility,
2. sampling rate of at least 100 Hz for dynamic testing,
3. specification of filters and cut-off frequency for determination of lateral acceleration,
4. option to measure “overriding force” torque via an internal sensor or an external device (e.g., steering robot).

Proposal to stipulate that “Automatic deactivation by the system of the direction indicator is required only if the lane change manoeuvre is initiated automatically, and if the direction indicator control is not fully engaged (latched position) during the lane change manoeuvre.” The proposal also would modify the high-speed test to end once the system has given an optical “hands-off” warning since the entire warning cascade is checked during the low-speed test. For M₂ and M₃ vehicles, the amendment allows a corrective steering function to use haptic signals as an alternative to acoustic signals for these categories of vehicles that are equipped with Lane Departure Warning System compliant with UN R130. This change would specify that the haptic warning may not be given solely via the steering wheel (e.g., provided in the driver’s seat).

Proposal to allow for the use of the maximum operable steering wheel angle of a steering system’s design in cases where the normalized angle as calculated under the regulation cannot meet the fixed values of the regulation (i.e., between 270 and 300 degrees). The intention is to enable approval of eventual systems (e.g., steer-by-wire) that may use low steering gear ratios.

Proposal to improve the robustness of the test procedure, including number of test runs and assessment of failures.
