Abstract: According to the requirements of ISO 362-1:2007 standard, ECE R51-03 series, and the newest draft of GB 1495 regulation, this paper introduces a kind of fast measuring method for noise emitted by accelerating motor vehicles. This fast measuring method uses an appropriate test process, and integrates and synchronously acquires the vehicle speed, engine speed, vehicle longitudinal acceleration, state of accelerator pedal, vehicle relative position and other test data, with the existing test equipments.

摘要： 结合ISO 362-1：2007、ECE R51-03系列以及最新的GB1495草案所述试验方法的新要求，采用适当的试验流程，在现有设备基础上，集成和同步采集车速、发动机转速、整车行驶过程中的纵向加速度、油门踏板状态、整车在试验场地上的相对位置等测量参数，整合出一种汽车加速行驶车外噪声快速试验方法。
