9. The IWG RD-ASEP Subgroup on UN Regulations Nos. 138 and 51 reported on their activities with the aim to find a satisfactory solution for the sound emissions of electric vehicles (EVs) and to update both UN Regulations (GRBP-81-18-Rev.1). For UN Regulation No. 51, the Subgroup agreed to introduce electric vehicles in the scope of Annex 7 (ASEP). For UN Regulation No. 138, the double target was to ensure an adequate level of safety due to the reduced audibility of quiet vehicles at lower speeds but to keep this additional sound (AVAS) level not too loud. GRBP also noted a request from the industry to “keep agreeable flexibility in vehicle sound design where environment is not at stake”.
11. GRBP recalled the status report of the IWG RD-ASEP Subgroup on UN Regulations Nos. 138 and 51 (GRBP-81-18-Rev.1) and the ensuing discussion (paragraphs 7 and 8 above).
