摘 要：根據(jù)電子真空泵的工作原理并結(jié)合整車(chē)應(yīng)用，基于相關(guān)驗(yàn)證經(jīng)驗(yàn)，提出降低真空泵運(yùn)轉(zhuǎn)噪音以改善整車(chē)NVH的思路和開(kāi)發(fā)經(jīng)驗(yàn)，對(duì)新能源汽車(chē)的電子真空泵噪音的降低有一定的指導(dǎo)作用。

關(guān)鍵詞：新能源 電子真空泵 噪音 NVH

Abstract：According to the working principle of the electronic vacuum pump and combined with the application of the vehicle， based on relevant verification experience， the idea and development experience of reducing the operating noise of the vacuum pump to improve the NVH of the vehicle are proposed， which has a certain guiding effect on the reduction of the noise of the electronic vacuum pump of the new energy vehicle.

Key words：new energy， electronic vacuum pump， noise， NVH

1 前言

新能源汽車(chē)缺少發(fā)動(dòng)機(jī)進(jìn)氣歧管，沒(méi)有可供助力器使用的真空源，此時(shí)真空助力器不能為駕駛者提供助力，影響行車(chē)安全。（剩余3329字）
