摘　　要：本文分析了制定中的国内外倒车提示音标准与电动车低速提示音、右转弯提示音、土方机械报警器等标准的区别与联系,比较了不同车外提示音在相同的试验距离下的声压级限值。分析了倒车提示音标准实施后,在实际的倒车工况中需要考虑的问题,结合相关车外提示音标准对该标准的试验方法和限值规定提供了建议。Differences and relations between the existing standards and the ones under development about vehicle reverse warning sound,alerting system of electric vehicles running at low speed,alert for vehicle turning right and earthmoving machinery audible travel alarms,etc.are analyzed in this paper.The sound pressure level limits of different kinds of exterior warning sound are compared in the same experimental distance.Potential problems that need to be considered in the practical reversing working condition are analyzed after the implementation of the reverse warning sound standard.Suggestions about experiment method and specifications for reverse warning sound standard are raised regarding relevant warning sound standards.
