扭矩傳感器簡介

在方(fang)向盤下(xia)邊的(de)(de)方(fang)向桿(gan)上(shang)找到(dao)助力電(dian)機，電(dian)機上(shang)一(yi)(yi)般(ban)有一(yi)(yi)個(ge)小鐵(tie)蓋(gai)護著的(de)(de)、帶(dai)四根線（帶(dai)有一(yi)(yi)個(ge)插頭）的(de)(de)就(jiu)是轉向助力扭矩傳感器，拆下(xia)小鐵(tie)蓋(gai)就(jiu)能(neng)看到(dao)。

電(dian)(dian)動(dong)助(zhu)(zhu)力轉向(xiang)系(xi)(xi)統(tong)主要由扭(niu)矩(ju)(ju)(ju)傳感器(qi)，車速(su)傳感器(qi)，電(dian)(dian)動(dong)機，減速(su)機構與電(dian)(dian)子控制(zhi)單元等組成。該系(xi)(xi)統(tong)通(tong)過扭(niu)矩(ju)(ju)(ju)傳感器(qi)感知駕駛員在轉向(xiang)操作(zuo)時(shi)方向(xiang)盤產(chan)生(sheng)的扭(niu)矩(ju)(ju)(ju)力和轉向(xiang)角(jiao)度，就會把操控信息轉換成數字信號(hao)輸入到控制(zhi)單元，再經過控制(zhi)單元對這(zhe)些信號(hao)進行運算得到一個最(zui)佳的力矩(ju)(ju)(ju)最(zui)后控制(zhi)驅使(shi)電(dian)(dian)動(dong)機工作(zuo)。以上就是(shi)整個電(dian)(dian)動(dong)助(zhu)(zhu)力系(xi)(xi)統(tong)構成和工作(zuo)的過程，不難看出扭(niu)矩(ju)(ju)(ju)傳感器(qi)在電(dian)(dian)動(dong)助(zhu)(zhu)力系(xi)(xi)統(tong)中是(shi)最(zui)為重要的器(qi)件之一。

扭矩傳感器的作用

扭(niu)矩(ju)(ju)傳(chuan)(chuan)感器(qi)在(zai)(zai)電(dian)動(dong)(dong)助(zhu)(zhu)(zhu)力(li)轉(zhuan)(zhuan)(zhuan)向(xiang)系統(tong)(tong)(tong)中的作用電(dian)動(dong)(dong)助(zhu)(zhu)(zhu)力(li)轉(zhuan)(zhuan)(zhuan)向(xiang)系統(tong)(tong)(tong)可以稱之為EPS，它就是一種直接依(yi)靠電(dian)機(ji)提供輔助(zhu)(zhu)(zhu)扭(niu)矩(ju)(ju)的動(dong)(dong)力(li)轉(zhuan)(zhuan)(zhuan)向(xiang)系統(tong)(tong)(tong)。在(zai)(zai)整個系統(tong)(tong)(tong)中，扭(niu)矩(ju)(ju)傳(chuan)(chuan)感器(qi)起(qi)到決(jue)定(ding)性(xing)作用。與傳(chuan)(chuan)統(tong)(tong)(tong)的液(ye)壓助(zhu)(zhu)(zhu)力(li)轉(zhuan)(zhuan)(zhuan)向(xiang)系統(tong)(tong)(tong)不同的是電(dian)動(dong)(dong)助(zhu)(zhu)(zhu)力(li)轉(zhuan)(zhuan)(zhuan)向(xiang)系統(tong)(tong)(tong)具有(you)性(xing)能(neng)(neng)(neng)應用上更(geng)(geng)大的優勢。它不光在(zai)(zai)需要(yao)轉(zhuan)(zhuan)(zhuan)向(xiang)時才啟動(dong)(dong)電(dian)機(ji)產(chan)生助(zhu)(zhu)(zhu)力(li)，這(zhe)樣能(neng)(neng)(neng)大大的減少發動(dong)(dong)機(ji)燃油(you)消(xiao)耗。電(dian)動(dong)(dong)助(zhu)(zhu)(zhu)力(li)能(neng)(neng)(neng)在(zai)(zai)各種行駛工況下(xia)提供最佳助(zhu)(zhu)(zhu)力(li)，減小由路面不平(ping)所引起(qi)電(dian)動(dong)(dong)機(ji)的輸出轉(zhuan)(zhuan)(zhuan)矩(ju)(ju)通(tong)過(guo)傳(chuan)(chuan)動(dong)(dong)裝(zhuang)置的作用而助(zhu)(zhu)(zhu)力(li)向(xiang)系的擾動(dong)(dong)，改善(shan)汽車(che)的轉(zhuan)(zhuan)(zhuan)向(xiang)特性(xing)，提高汽車(che)的主動(dong)(dong)安全性(xing)。和(he)液(ye)壓助(zhu)(zhu)(zhu)力(li)相(xiang)比(bi)沒有(you)液(ye)壓回路，調整和(he)檢測更(geng)(geng)容易，裝(zhuang)配自動(dong)(dong)化程度(du)更(geng)(geng)高，且可通(tong)過(guo)設置不同的程序，快速以及不同車(che)型匹配，縮(suo)短生產(chan)和(he)開發周期。

扭(niu)矩(ju)傳感器的作用是測量動態(tai)扭(niu)矩(ju)和靜態(tai)扭(niu)矩(ju)，其(qi)檢測穩定性、抗干擾性，以及精度(du)都很好(hao)，每次使(shi)用不需要調整為零。
