Draft informal group response to GRVA general agreement to address AEBS robustness and uncertainties of the test method.

Proposal the clarify the test method for the evaluation of performance of energy sources and energy storage devices under Annex 7. In particular, the proposal clarifies that the measurement is made on the ninth brake application.

EDR/DSSAD informal group co-chairs’ draft text.

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 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 from the AEBS informal group to improve the assessment of AEBS robustness.

Proposal to increase maximum lateral acceleration limit values up to 4m/s² for speeds up to 80 km/h for M1/[N1] category vehicles, provided there is no heavy rain and ambient air temperatures are above 4°C.

Proposal for a maximum time of up to 15 seconds for an Automatically Commanded Steering Function (ACSF) of Category C to start a lane change.

Proposal to stipulate that “Automatic deactivation by the system of the direction indicator is required only if the lane change manoeuvre is initiated automatically, or if the direction indicator control is not fully engaged (latched position) during the lane change manoeuvre.”

Since an Automatically Commanded Steering Function (ACSF) of Category B is required to demonstrate compliance with regard to the warning cascade under testing at low speed, it is proposed to stop the high-speed test after the system has given the optical warning, meaning it has correctly detected the hands to be off the steering wheel.

Proposal to allow a corrective steering function to use haptic signals as an alternative to acoustic signals for M₂ and M₃ vehicles equipped with Lane Departure Warning System compliant with UN R130. The proposal 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 permit a function to cope with temporary driver inability to control the vehicle (e.g. caused by a health problem). The proposed emergency steering function of type (c) would warn and possibly revive the driver while automatically performing emergency lane change(s) with the aim to bring the vehicle to a standstill in an area with a low risk of collision (“target stop area” e.g. hard shoulder).

Proposal to align approval numbers and markings under UN R90 with Schedule 4 of Revision 3 to the 1958 Agreement. Please note that WP.29 adopted document WP.29/2019/47 as Supplement 5 to the 02 series of amendments to UN R90 during its June 2019 session. Therefore, this proposal (if adopted) would be Supplement 6.

Proposal from VMAD Subgroup 1a on “traffic disturbance test scenarios” for on-highway, low-speed automated lane keeping systems.

Proposal to improve and clarify the text of the Regulation.
