UN R157: Proposal for a supplement to the original version and to the 01 series of amendments (Netherlands)
GRVA/2023/8 08 Mar 2023 Working Party Electromagnetic Compatibility Electromagnetic Compatibility Uniform provisions concerning the approval of vehicles with regard to electromagnetic compatibility Automated Lane-Keeping Systems (ALKS) Automated Lane-Keeping Systems Uniform provisions concerning the approval of vehicles with regards to Automated Lane Keeping System Proposal to align the text with the guidelines on UN regulatory procedures and transitional provisions in UN Regulations (document ECE/TRANS/WP.29/1044/Rev.3). Under the guidelines, a UN Regulation (in this case, UN R157) making reference to the provisions of another UN Regulation (in this case, UN R10) shall not require actual approval to that UN regulation but simply refer to the provisions of that UN Regulation. GRVA/2023/0008
UN R140: Proposal for amendments (OICA)
GRVA/2023/9 08 Mar 2023 Working Party Electronic Stability Control Systems ESC Systems Uniform provisions concerning the approval of passenger cars with regard to electronic stability control systems Proposal to add the text, "In case that saturation of the front tyres happens before the above calculated magnitude angle, this angle may be used as the final steering amplitude, but only if this angle is greater or equal to 6.5 A.” based on the following justification:<ol><li>Reaching fixed amplitude, i.e., fixed steering wheel angular speed due to given 0.7 Hz sine frequency, needs much more torque with quick steering gear ratio systems than with slow steering gear ratio systems, and produces much more wheel steer.</li><li>Car behavior (yaw rate, lateral acceleration and thus trajectory) is similar for all amplitudes above approx. 7 to 8 A (i.e., more than 7 times the steering wheel angle corresponding to 0.3 g), because front tires are saturated. More steer of the tires doesn’t provide more lateral force, so yaw rate and lateral acceleration don’t increase. Continuing to increase steering wheel amplitude after front tire saturation doesn’t give more information.</li><li>There might appear in the future some vehicles which have significantly low steering gear ratio (i.e., quick steering characteristics) and may need too much steering wheel torque to achieve the 270 degrees sine amplitude at 0.7 Hz (not reachable by conventional steering robots), then jeopardizing the easy approval of future beneficial steering equipment e.g. steering-by-wire systems.</li></ol> GRVA/2023/0009
UN R13: Proposal for amendments (UK)
GRVA/2023/10 08 Mar 2023 Working Party Heavy-Duty Vehicle Braking Heavy-Duty Braking Uniform Provisions Concerning the Approval of Vehicles of Categories M, N and O with regard to Braking Proposal for amendments to Annex 18 regarding special requirements for electronic control systems and for related transitional provisions for its entry into force. GRVA/2023/0010
UN R90: Proposal for a Supplement 12 to the 01 series of amendments (CLEPA)
GRVA/2023/11 08 Mar 2023 Working Party Replacement Brake Linings, Discs, and Drums Replacement Brake Components Uniform provisions concerning the approval of replacement brake lining assemblies, drum brake linings and discs and drums for power-driven vehicles and their trailers Proposal to clarify the packaging and labelling requirements for some types of brake lining assemblies, which could be fitted for various different applications and to allow the option of using a QR code (or another type of digital data carrier) to replace some information printed on or included in the packaging. GRVA/2023/0011
UN R90: Proposal for a Supplement 11 to the 02 series of amendments (CLEPA)
GRVA/2023/12 08 Mar 2023 Working Party Replacement Brake Linings, Discs, and Drums Replacement Brake Components Uniform provisions concerning the approval of replacement brake lining assemblies, drum brake linings and discs and drums for power-driven vehicles and their trailers Proposal to clarify the packaging and labelling requirements for some types of brake lining assemblies, which could be fitted on various different applications and to allow the option of using a QR code (or another type of digital data carrier) to replace some information printed on or included in the packaging. GRVA/2023/0012
UN R90: Proposal for a Supplement 11 to the 02 series of amendments (FEMFM)
GRVA/2023/13 09 Mar 2023 Working Party Replacement Brake Linings, Discs, and Drums Replacement Brake Components Uniform provisions concerning the approval of replacement brake lining assemblies, drum brake linings and discs and drums for power-driven vehicles and their trailers Proposal to include the option of using a QR code (or another type of digital data carrier) in place of the paper fitting instructions physically included in the packaging. GRVA/2023/0013
UN R90: Proposal for a Supplement 12 to the 01 series of amendments (FEMFM)
GRVA/2023/14 09 Mar 2023 Working Party Replacement Brake Linings, Discs, and Drums Replacement Brake Components Uniform provisions concerning the approval of replacement brake lining assemblies, drum brake linings and discs and drums for power-driven vehicles and their trailers Proposal to include the option of using a QR code (or another type of digital data carrier) in place of the paper fitting instructions physically included in the packaging. GRVA/2023/0014
