Abstract:

本文以新能源汽车在中国的发展现状和世界各国因为新能源汽车行驶时的低噪声引发的行人安全问题而相继制定电动汽车行车标准为背景，首先，介绍了各类汽车的概念包括传统的内燃机汽车以及三类新能源汽车。之后，分析了这四类汽车行驶时的噪声并说明了噪声产生的原因。最后，从速度引起汽车噪声特性变化的角度对比了不同类型汽车的噪声差异。
This article takes the background of the development status of new energy vehicles in China and the successive development and implementation of electric vehicle driving standards in the world due to pedestrian safety issues caused by new energy vehicles driving at low speeds. Firstly, it introduces the concepts of various types of vehicles including traditional internal combustion engine vehicles and three types of new energy vehicles. After that, the noises of these four types of vehicles during driving are analyzed and the reasons for the noises are explained. Finally, the noise differences of different types of vehicles are compared from the perspective of changes of the noise of vehicles caused by speed changes.
