        1.方案概述

        輪轂電(dian)(dian)機(ji)在日(ri)常使用(yong)過程中，其(qi)(qi)載重(zhong)(zhong)能力以及(ji)響應速度的(de)快慢往(wang)往(wang)對(dui)使用(yong)過程的(de)體驗起(qi)著(zhu)較大(da)的(de)影響作(zuo)用(yong)。當電(dian)(dian)動(dong)車載有(you)較重(zhong)(zhong)負載時(shi)，只有(you)電(dian)(dian)機(ji)能輸(shu)(shu)出(chu)足夠的(de)扭矩(ju)才能使其(qi)(qi)順(shun)利的(de)起(qi)步運(yun)行，若電(dian)(dian)機(ji)輸(shu)(shu)出(chu)的(de)額定(ding)扭矩(ju)相對(dui)較小，則(ze)在重(zhong)(zhong)載或(huo)是(shi)爬坡等(deng)高負載情況下，電(dian)(dian)機(ji)的(de)電(dian)(dian)流會迅速增(zeng)大(da)，導致其(qi)(qi)效率降低(di)并伴隨大(da)量發熱，限制動(dong)力輸(shu)(shu)出(chu)。

        2.具體的實施方案

        為了提(ti)高(gao)(gao)電(dian)機(ji)輸出(chu)轉(zhuan)(zhuan)矩同時提(ti)高(gao)(gao)電(dian)動(dong)(dong)車的響(xiang)應速度(du)，同時結合實(shi)際(ji)設計，我們可以對電(dian)動(dong)(dong)車采用(yong)輪轂電(dian)機(ji)并配以減速驅(qu)(qu)動(dong)(dong)的方案(an)。輪轂電(dian)機(ji)較傳統電(dian)機(ji)具有(you)一(yi)系列(lie)優勢，包括：響(xiang)應速度(du)快(kuai)、轉(zhuan)(zhuan)矩控(kong)(kong)制精度(du)高(gao)(gao)、可提(ti)供(gong)驅(qu)(qu)動(dong)(dong)和(he)制動(dong)(dong)轉(zhuan)(zhuan)矩、可獨立進行(xing)轉(zhuan)(zhuan)矩控(kong)(kong)制、使用(yong)壽命長等。

        輪轂電機高度(du)集成化，將電機、控制器和DCDC直接安裝于(yu)驅動(dong)(dong)(dong)輪內(nei)，將給電動(dong)(dong)(dong)車動(dong)(dong)(dong)力系統的布置(zhi)帶來巨大變革和優(you)化，包括(kuo)： (1)系統效率提(ti)高；(2)轉矩(ju)響應精度(du)高、響應速度(du)快(kuai)；(3)動(dong)(dong)(dong)力系統布置(zhi)自由度(du)高,整車輕量(liang)化程度(du)大幅提(ti)高。 

        高(gao)性能(neng)：比功率高(gao)，質量輕，體積小(xiao)，噪(zao)聲小(xiao)，成本低

        高度集成化(hua)：電機，控制器，DC/DC 共(gong)殼(ke)體

        控制(zhi)策略：永磁同步電機的(de)控制(zhi)使用(yong)FOC矢量控制(zhi)

        控(kong)制(zhi)系統：安(an)全控(kong)制(zhi)與故障診斷
