96. The expert from IMMA introduced GRVA-11-22, modifying ECE/TRANS/WP.29/GRVA/2021/26, with amendments to the stop lamp activation criteria He proposed that GRVA would harmonise stop lamp activation thresholds for regenerative braking in UN Regulation No. 78 with new provisions in UN Regulation No. 13-H.

97. The expert from Japan stated that the proposal can be supported. He noted however that automatically commanded braking was not considered in the current text of UN Regulation No. 78. He added that, if automatically commanded braking would be introduced in UN Regulation No. 78, then consistency between UN Regulation No. 78 and UN Regulation No. 13-H would be needed.
