电动汽车低速提示音发展研究及试验实施

Acoustic Vehicle Alerting System of Electric Vehicles Development Research and Test Implementation

电动模式下的低速行驶安全被广泛关注,AVAS(Acoustic Vehicle Alerting System)应运而生,目的是警示行人降低电动模式下低速行驶的事故率。文章阐述AVAS系统的产生背景,分析中国、美国、欧盟在AVAS标准上的差异性,依据电动汽车低速提示音国家标准,组织实施现场试验,分析声级限值和频率数据,验证试验方法可操作性,对后续试验优化具有指导作用。

Safety of low speed driving in electric mode are widely concerned.AVAS(Acoustic Vehicle Alerting System)emerged as the times require,to alert pedestrians and reduce the accident rate of low speed driving in electric mode.This paper describes the background of AVAS,and analyzes the differences of AVAS standards among China,United States and European Union.According to national standard of AVAS,test is implemented,sound level limit and frequency data are analyzed,the operability of the test method is verified,it provides guidance in the optimization of subsequent test.
