摘要
依据ISO 362—1:2007标准中关于M1类车的规定,对该类车辆进行了车外噪声测试试验,并根据测试结果讨论了该标准中几个不明确的地方。指出,对于配备既能锁挡也能不锁挡变速器的M1类车,应选用加速度接近参考加速度的挡位进行测试;对于配备能锁挡变速器的M1类车,无论选择1个挡位还是2个挡位进行测试,最后的结果都是一致的;对于M1类混合动力车辆,车辆的额定功率由电机和发动机的有效功率之和决定;对于M1类和M2类跨类车,M1类车的噪声测试结果比M2类车要大。
exterior noise test was made to category M1 vehicle according to stipulation of standard ISO 362--1： 2007. According to the test results several obscure places in this standard were discussed. It is pointed out that in the case of category M1 vehicle with gear-box with locked gear ratios as well as unlocked gear ratios, the gear ratio that its acceleration is close to the reference acceleration should be chosen and tested; In the case of category M1 vehicle with gear-box with locked gear ratios, the final results are consistent no matter which gear ratios are chosen; In the case of category M1 hybrid vehicle, the rated power should be decided by the sum of available electric and combustion power; In the case of category M1 and M2 cross-over vehicles, noise of category M1 vehicle is greater than that of category M2 vehicle.
