车辆右转弯提示音试验方法分析及验证

Analysis and Verification of Vehicle Turning Right Alert Test Method

《车辆右转弯提示音要求及试验方法》标准(报批稿)规定了右转弯提示音装置及配备该装置的整车需要满足的提示音条件。通过分析该报批稿的相关要求,对整车右转弯提示音频率、声压级的数值要求进行了试验论证,对比了整车提示音和零部件级别即提示音装置本身的声压级,通过试验证明了该数值的合理性,并对后续标准实施和试验提出了合理化建议。

The standard Test method and requirements of alert for vehicle turning right(draft to be approved)has defined the sound condition of vehicle turning right alert system and the vehicle equipped with this system.This paper analyzes the relate requirements of the standard,verifies the numerical requirements on alert sound frequency and sound pressure level of vehicle turning right,compares the sound pressure level of vehicle alert sound and component i.e.alert system.It proves that the sound condition defined in the standard is reasonable through verification experiment,and provides reasonable suggestions on standard implementation and experiment.
