Pursuant to GRPE work on vehicle propulsion system definitions (VPSD informal group; see document WP.29-165-17), this GRSP proposal would update the definition of the acronym “REESS” to refer to “rechargeable electrical energy storage system” across the passive safety regulations and currently proposed texts that make use of this acronym.

Proposal to enable approval testing under UN R137 as an alternative to UN R12 in order to avoid redundant testing requirements. The proposal adds references to the steering gear provisions of UN R137 (full width frontal impact) as a compliance alternative in parallel to the current references similarly allowing compliance via provisions in UN R94 (offset deformable barrier frontal impact).
