This standard is developed in accordance with the rules given in GB/T 1.1-2009. This standard is redrafted by reference to, but is not equivalent to, ECE-R138 Uniform provisions concerning the approval of quiet road transport vehicle with regard to their reduced audibility. This standard was proposed by the Ministry of Industry and Information Technology of the People's Republic of China. This standard is under the jurisdiction of the National Technical Committee of Auto Standardization (SAC/TC 114). Acoustic vehicle alerting system of electric vehicles running at low speed 1 Scope This standard specifies requirements and test methods for speed range, sound pressure level limits, frequency requirement, sound type, pause switch, etc., of acoustic vehicle alerting system of electric vehicles running at low speed (hereinafter referred to as "AVAS"). It is applicable to battery electric vehicles (BEVs) of categories M1 and N1, hybrid electric vehicles (HEVs) with pure electric driving mode, and fuel cell electric vehicles (FCEVs). 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the normative document (including any amendments) applies.
