UN R13: Proposal for a supplement to the 11 series of amendments
Document GRVA/2022/8
1 December 2021

Proposal by the expert from the European Association of Automotive Suppliers (CLEPA) to include provisions for the type approval of Electro-Mechanical Braking (EMB) systems as state-of-the-art braking systems. This document supersedes ECE/TRANS/WP.29/GRVA/2021/24.

83. The expert from CLEPA presented GRVA-13-47, reflecting the ongoing discussions regarding the development of provisions for the type approval of electromechanical brakes (see current status in GRVA-13-05, amending ECE/TRANS/WP.29/GRVA/2022/8).

84. The expert from the United Kingdom of Great Britain and Northern Ireland introduced GRVA-13-19 proposing amendments to Annex XVIII on the assessment of complex electronic systems, based on the most recent provisions introduced in UN Regulation No. 157. He recalled that the review of the complex electronic assessment provisions was initiated when introducing Automatically Commanded Steering Functions of categories A and B in UN Regulation No. 79 and that it was agreed at that time, that UN Regulations Nos. 13 and 13-H would need to be updated, too.

85. The expert from OICA inquired the reason why the provisions in UN Regulation No. 157 were used as a reference and why not simpler versions such as the one in UN Regulation No. 79. He recalled that the complexity of systems covered by UN Regulation No. 79 (i.e. Levels 0 to 2) differed from those in UN Regulation No. 157 (i.e. Level 3). He stated that the assessment for a power steering, an anti-lock braking system or an electronic stability function would not necessarily need to be as extensive as for ALKS.

86. The expert from CLEPA supported that Annex XVIII is updated in the context of the activities related to electro-mechanical brakes.

87. GRVA noted CLEPA’s intention to submit an official document, on the basis of GRVA-13-05 for consideration at the September 2022 session of GRVA. GRVA noted the proposal by United Kingdom of Great Britain and Northern Ireland to upgrade Annex XVIII of UN Regulation No. 13 and discussed whether or not to merge it with CLEPA’s document, mentioned above.

8. (c) | Clarifications
8. (b) | Electromechanical Brakes

80. GRVA noted the oral report of the expert from CLEPA concerning ongoing discussions regarding electromechanical brakes (ECE/TRANS/WP.29/GRVA/2022/8) and agreed to consider a revised document at its May 2022 session.

8. (b) | Electromechanical Brakes

87. The expert from CLEPA briefly introduced ECE/TRANS/WP.29/GRVA/2020/24. He explained that his organization invited GRVA participants to participate in an informal meeting that took place before the GRVA session and that CLEPA received some suggestions and comments from Contracting Parties that his members wanted to address.

88. GRVA agreed to review a revised proposal at its next session.
