Questions raised by OICA in response to the German proposal to clarify electrical braking system and energy supply line requirements with regard to towed trailers, including proposals for voltage specifications and inclusion of electro-hydraulic transmission devices within such systems.
11. The expert from Germany presented ECE/TRANS/WP.29/GRRF/2013/29 introducing provisions for electrical or hydraulic transmissions for brake systems. The expert from OICA, with reference to GRRF-75-13, answered to this proposal. GRRF noted a number of comments and agreed to resume consideration of this item at its next session on the basis of a revised document that the expert from Germany volunteered to prepare.
