Proposal to clarify the pretest conditions for measuring steering effort under a failure condition.

Proposal to insert new Paragraph 6.2.5.1.1. into UN R79 (Supplements 17 to 03 series and 12 to 04 series):

• Insert new Paragraph 6.2.5.1.1. into UN R79
• If requested by the vehicle manufacturer, the vehicle may undergo up to ten figure-eight manoeuvres, where each loop of the figure is 40m diameter at 10km/h speed with intact steering equipment, before the measurement of steering efforts with a failure in the steering equipment
• Clarify pre-test conditions for measuring steering effort under a failure condition
• Stabilize power steering oil temperature, particularly for vehicles of category N₃ and M₃

Proposal to amend paragraph 5.2.3.3 to clarify that samples shall be subjected to the heat resistance test described in Part 1 of Annex 6, prior to the tests described in Parts 1 and 2 of Annex 6 paragraphs 5.2.5 and 5.2.6. Proposal to amend paragraph 5.1.7 to correct the reference in Tables 4 and 5 from Part 4 to Part 5 of Annex 6 for the Rear face test. Proposal to amend Annex 5, paragraph 8.1.4 to correct the cross-reference from paragraph 5.9.4.2.1 to paragraph 5.3.4.2.1.

Proposal to amend para. 5.3.3.2. to clarify that steering shall remain possible with performance laid down in para. 6. for the intact steering system in case of control transmission failure, amend para. 6.1.1. to specify that tests shall be conducted on a level surface affording good adhesion at ambient temperature between 0°C and 45°C, with provisions for deviating conditions at manufacturer request with Technical Service agreement, and insert new para. 6.2.5.1.1. to permit vehicle manufacturers to request at least 10 “figure of eight” manoeuvres with 40 m diameter loops at 10 km/h speed prior to measurement of steering efforts with steering equipment failure.

Proposal to amend para. 6.1.5. to state that sensors, cameras, radar devices, etc. being part of driver assist systems and automated driving systems may become damaged, disoriented or broken due to an impact as long as basic braking and steering performance remain intact. The amendment enables application of UN R42 to vehicles equipped with an Automated Driving System.

International vehicle regulations do not include safety requirements for power-operated components such as doors, tailgates, and seats, with the exception of power-operated windows, sunroofs, and partitions covered by UN R21. Recent incidents involving entrapment hazards demonstrate the need for WP.29 to pay attention to this issue and discuss the enhancement of vehicle regulations from a long-term perspective, including which GRs should amend which regulations.
