Proposal to introduce provisions for the approval of electromechanical braking systems.

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.

96. The expert from CLEPA updated GRVA (GRVA-14-52) on the outcome achieved following the weekly meetings organized by CLEPA since February 2022, with both industry group representatives and contracting parties regarding the drafting of provisions for the approval of Electromechanical Brakes (EMB) for electric powered trucks and coaches. EMB was presented for the first time to GRVA at the seventh session of GRVA (see ECE/TRANS/WP.29/GRVA/2020/21). The original proposal has been iteratively updated following GRVA guidance (see ECE/TRANS/WP.29/GRVA/2021/24, ECE/TRANS/WP.29/GRVA/2022/8 and GRVA-13-05). He presented the recent developments related to the effect of aging of the electrical energy storage device. He presented GRVA-14-12, the most recent draft superseding GRVA-13-05. He kindly invited interested contracting parties to join their activities.

97. GRVA noted the presentation of the expert from CLEPA on EMB and their ambition to submit an amendment proposal to UN Regulation No. 13, based on GRVA-14-12, for consideration at the next session.

Proposal to introduce requirements for the type approval of Electro-Mechanical Braking (EMB) systems.

65. The expert from CLEPA presented GRVA-07-68, introducing ECE/TRANS/WP.29/GRVA/2020/21 with provisions for the type approval of Electromechanical Braking systems. The expert from OICA introduced GRVA-07-46, aimed at improving and finalizing some open items in the CLEPA proposal. The expert from the Netherlands stated that some open items should still be finalized before adoption, such as para. 5.1.1.2. and should address the deterioration over time of the state of charge and the state of health. He also mentioned issues related to temperature differences during a trip that might impact the performance of the system. GRVA agreed to resume consideration of this matter at its next session.

98. The expert from CLEPA presented GRVA-09-06, introducing ECE/TRANS/WP.29/GRVA/2020/21, as amended by GRVA-09-05, providing provisions for the type approval of trucks equipped with electromechanical brakes. He clarified that no trailer with electromechanical brakes was considered in the proposal. He explained the benefits of such system for hybrid electric and electric vehicles. He acknowledged that further work was needed to develop Periodic Technical Inspection and electric storage devices requirements.

99. GRVA agreed to review a revised proposal based on GRVA-09-05, as formal document, at its next session.
