Kodi chowongolera magalimoto ndi chiyani?
Chowongolera magalimoto (MCU) ndiye gawo lalikulu lamagetsi la magalimoto atsopano amphamvu, lomwe lili pakati pa batire yamagetsi ndi mota yoyendetsera. Imayang'anira kwambiri kusintha mphamvu yolunjika kukhala mphamvu yosinthira kuti injiniyo igwire ntchito, ndikusintha liwiro la injiniyo, mphamvu yake ndi komwe ikupita motsatira malangizo oyendetsera, kukwaniritsa kuwongolera momwe galimotoyo imayambira, ikuyendera mofulumira, imayimitsa, imakwera ndi zina zomwe imayendetsa.
Ntchito yaikulu
Youdaoplaceholder0 Kutembenuza mphamvu yamagetsi : Sinthani mphamvu yamagetsi yolunjika kuchokera ku batri yamagetsi kukhala mphamvu yamagetsi yosinthira magawo atatu kuti iyendetse mota ya AC. Njirayi imachitika kudzera mu inverter yamkati, yomwe imagwiritsa ntchito zida zosinthira za semiconductor monga ma transistors kapena ma IGBT kuti ilamulire kuchuluka ndi kutalika kwa mphamvu yamagetsi.
Youdaoplaceholder0 Liwiro ndi kuwongolera mphamvu: Sinthani liwiro la injini ndi mphamvu yake malinga ndi zofunikira pa kuyendetsa (monga malo a giya, accelerator, brake), ndikupeza kuwongolera kolondola kudzera mu ukadaulo wa PWM (pulse width modulation).
Youdaoplaceholder0 Chitetezo cha dongosolo : Ili ndi chitetezo chochulukirapo, kuzindikira zolakwika, chitetezo cha malo olowera batire ndi njira zina zowonetsetsa kuti dongosololi likugwira ntchito bwino.
Youdaoplaceholder0 Kubwezeretsa Mphamvu : Pa nthawi yoyendetsa mabuleki, mphamvu ya kinetic imatha kusinthidwa kukhala mphamvu yamagetsi kudzera mu inverter kuti ijayire batri, motero kumawonjezera liwiro loyendetsa.
Zigawo zazikulu
Gawo lowongolera la Youdaoplaceholder0 : Limakonza malangizo oyendetsa ndi kupanga zizindikiro za PWM kuti liwongolere inverter.
Youdaoplaceholder0 power module : Ili ndi IGBT ndi zida zina zosinthira kuti zikwaniritse kusintha kwa magetsi.
Sensa ya Youdaoplaceholder0 : imayang'anira momwe injini ilili (monga kutentha, liwiro) ndikuyibwezera ku dongosolo lowongolera.
Youdaoplaceholder0 dongosolo lochotsa kutentha : limasunga kutentha kokhazikika kogwira ntchito pansi pa mikhalidwe yolemera kwambiri.
Kagwiridwe ka ntchito ka chowongolera mota kumakhudza mwachindunji luso loyendetsa ndi kugwiritsa ntchito bwino mphamvu zamagalimoto amagetsi ndipo ndi malo ofunikira olumikizira batire yamagetsi ndi mota yoyendetsera.
Chowongolera magalimoto ndi gawo lofunika kwambiri la magalimoto amagetsi, ndipo ntchito zake zazikulu ndi izi:
Liwiro ndi kuwongolera mphamvu
Liwiro la injini ndi mphamvu yake zimasinthidwa malinga ndi malangizo monga accelerator ndi brake. Voltage ndi ma frequency ake zimayendetsedwa kudzera muukadaulo wa PWM kuti zikwaniritse malamulo olondola a liwiro, kukwaniritsa zofunikira zoyendetsera monga kuthamangitsa, kutseka, ndi kukwera mapiri.
Kusintha kwa mphamvu ndi kuyendetsa
Mphamvu yolunjika yochokera ku batire yamagetsi imasinthidwa kukhala mphamvu yosinthira kuti iyendetse mota, ndipo njira yamagetsi imasinthidwa kudzera mu inverter kuti ilamulire kuzungulira kwa mota kutsogolo ndi kumbuyo. Mukayimitsa, mphamvu ya kinetic imatha kusinthidwa kukhala mphamvu yamagetsi ndikubwezeredwa ku batire.
Chitetezo cha dongosolo ndi matenda
Yang'anirani magawo monga kutentha kwa injini ndi magetsi, kuzindikira zolakwika nthawi yomweyo (monga kutentha kwambiri ndi kupitirira muyeso), ndipo tengani njira zodzitetezera kuti mupewe kuwonongeka. Nthawi yomweyo, lankhulanani ndikugawana deta ndi machitidwe ena (monga BMS) kudzera mu netiweki ya CAN.
Kulamulira koyankha kwamphamvu
Mphamvu yamagetsi ndi mphamvu yamagetsi zimasinthidwa paokha kudzera mu ma algorithms owongolera ma vector kuti zitheke kuyankha mwachangu malangizo oyendetsa. Kusintha kosalala panthawi yoyambira/kuyimitsa kuti muchepetse kugwedezeka.
Zolakwika za chowongolera mota m'magalimoto atsopano amphamvu zimaonekera makamaka monga kuchepa kwa mphamvu, kuvuta poyambira, kuchuluka kwa kugwiritsa ntchito mphamvu ndi mavuto ena. Zomwe zimayambitsa ziyenera kuweruzidwa mokwanira pamodzi ndi zochitika za zolakwika.
Zizindikiro zofala za zolakwika
Youdaoplaceholder0 Kuchepa kwa mphamvu: Chopondera cha accelerator chimayankha pang'onopang'ono, zomwe zimapangitsa kuti galimotoyo ikhale yovuta kuthamangitsa liwiro ndikuchepetsa liwiro lalikulu.
Youdaoplaceholder0 Kuyambitsa kosayenera : Pakhoza kukhala vuto poyambitsa, kuyesera kolephera kangapo kuyambitsa, kapena phokoso/kugwedezeka kosayenera panthawi yoyambitsa.
Youdaoplaceholder0 Kugwiritsa ntchito mphamvu mopitirira muyeso: Kulephera kwa chowongolera kungayambitse kuchepa kwa magwiridwe antchito a injini komanso kufupika kwa malo oimika magalimoto.
Youdaoplaceholder0 Chizindikiro cha kuwala kwa cholakwika : Chida chowunikira chikuwonetsa kuwala kwa cholakwika cha dongosolo lamagetsi kapena kuwala kwa cholakwika cha dongosolo la mota.
Njira yodziwira vuto
Mayeso oyambira a Youdaoplaceholder0:
Onetsetsani ngati magetsi amagetsi ndi abwinobwino (gwiritsani ntchito multimeter kuti muyese ngati magetsi a 5V ndi osazolowereka)
Yang'anani ngati pali vuto la kutentha kwambiri mu dera lalikulu la chowongolera (machubu 6 a MOS switch)
Kuzindikira chizindikiro cha Youdaoplaceholder0 :
Yesani kusintha kwa magetsi mukatembenuza chogwirira (mtundu wabwinobwino: 0-4.2VDC)
Onani ngati mawaya olumikizira ndi omasuka kapena atha ntchito
Mayeso ena a Youdaoplaceholder0 :
Ngati kukana kwa kagalimoto katatha pambuyo pochotsa mizere itatu yokhuthala ya mota, ikhoza kukhala vuto la wowongolera
Gwiritsani ntchito zida zaukadaulo (monga multimeter) kuti muyesere magawo monga diode ndi voltage yogwirira ntchito
Kusanthula kwa Zoyambitsa Zolakwika
Youdaoplaceholder0 Kuwonongeka kwa zida: Kukalamba kapena kutenthedwa kwambiri kwa zida zamagetsi zamkati (monga ma module a IGBT)
Vuto la kulumikizana kwa Youdaoplaceholder0 : Mizere yazizindikiro yotayirira komanso yosweka imapangitsa kuti zizindikiro zowongolera zitayike
Youdaoplaceholder0 Chilema cha kapangidwe : kapangidwe kosakwanira kotaya kutentha kapena kasinthidwe kosayenera ka magawo a dera
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Malingaliro a kampani Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa MG&MAXUSzida zamagalimoto zalandiridwa kugula.
