摘　　要：阐述了M1类车辆依据ISO362-1:2007《道路车辆加速行驶噪声测量工程法》的试验过程及数据处理方法,并结合实例进行验证。阐述了目标加速度值和参考加速度值的内涵。针对测试过程中存在的挡位初步选择、入线速度及预加速距离估算等技术难点,提出了一种实用方法:在噪声测试前采用速度、加速度、位移数据采集设备及触发装置对样车进行加速试验,通过对车辆加速特性进行分析,即可快速解决上述技术问题。The test process and data processing method of Category M1 vehicle in accordance with ISO 362--1： 2007 ＂Measurement of noise emitted by accelerating road vehicles--Engineering method＂is, introduced and verified with example in this paper. Meanings of target acceleration and reference acceleration are also analyzed.And several technical problems exist in the test procedure,e.g.gear ratio selection,calculation of test speed and pre-aceeleration distance.These problems can be solved quickly through acceleration test using speed,acceleration and shift data acquisition equipments and trigger before noise test and the succeeding acceleration characteristics analysis of vehicles.
