Kodi choyendetsa chanzeru cha magudumu anayi chomwe chimabwera pamitundu yonse ya LI L6 ndichofunika bwanji kuti chigwiritsidwe ntchito tsiku lililonse?

Vuto lodziwika bwino la magalimoto oyendetsa kumbuyo ndi "kuyendetsa", komwe kumachitika chifukwa cha mawilo akumbuyo akudutsa malire a mawilo akutsogolo akamakhota, zomwe zimapangitsa kuti mawilo akumbuyo aziyenda, ndiye kuti, kuwongolera.

Kunena zongoyerekeza, njira ya "kukwera ndi kupondaponda" yokhala ndi magudumu anayi imakhala yabwinoko komanso kumamatira kuposa kuyendetsa magudumu awiri, imakhala ndi mawonekedwe ogwiritsira ntchito magalimoto olemera, ndipo imatha kuwongolera bwino misewu yoterera kapena yamatope. Ndipo kukhazikika, komanso kuthekera kodutsa, kumathanso kupititsa patsogolo chitetezo chagalimoto, ndipo ndi njira yabwino kwambiri yoyendetsera magalimoto.
Ndi kutchuka kosalekeza kwa magalimoto amagetsi ndi magalimoto osakanizidwa, gulu la magudumu anayi pang'onopang'ono limakhala lovuta kwambiri. LI L6 itakhazikitsidwa, ogwiritsa ntchito ena anali ndi chidwi, ndi gulu liti la LI L6's four-wheel drive?

Titha kupanga fanizo ndi magudumu anayi agalimoto yamafuta. Magalimoto anayi oyendetsa mafuta nthawi zambiri amagawidwa m'magalimoto anayi anthawi zonse, anthawi zonse anthawi zonse komanso ma gudumu anthawi yake.

Part Time 4WD tingamvetse ngati "pamanja kufala" pagalimoto magudumu anayi. Mwiniwake wagalimoto amatha kuweruza paokha malinga ndi momwe zinthu zilili ndikuzindikira ma gudumu awiri kapena magudumu anayi poyatsa kapena kuyimitsa mlanduwo. Sinthani.

Kuyendetsa kwanthawi zonse kwa magudumu anayi (All Wheel Drive) kumakhala ndi kusiyana kwapakati komanso kodziyimira pawokha kopanda malire kwa ma axles akutsogolo ndi kumbuyo, omwe amagawa mphamvu yoyendetsera matayala anayi molingana. Monga momwe dzinalo likusonyezera, mawilo anayi amatha kupereka mphamvu yoyendetsa galimoto nthawi iliyonse komanso pansi pa ntchito iliyonse.

Real-time 4WD imatha kusinthana ndi ma wheel-wheel drive mode ngati kuli koyenera, ndikusunga ma gudumu awiri nthawi zina.

M'nthawi ya magalimoto oyendetsa magudumu anayi, popeza gwero lamagetsi ndi injini yokhayo yomwe ili kutsogolo, kupanga mitundu yosiyanasiyana yoyendetsa ndikukwaniritsa kugawa kwa torque pakati pa ma axles akutsogolo ndi kumbuyo kumafunikira zida zamakina zovuta, monga ma shafts akutsogolo ndi kumbuyo ndi milandu yosinthira. , multiplate clutch center differential, ndipo njira yolamulira ndi yovuta. Kawirikawiri zitsanzo zapamwamba zokha kapena mitundu yapamwamba imakhala ndi magudumu anayi.

Zinthu zasintha munthawi yamagalimoto amagetsi anzeru. Pamene teknoloji ya galimoto yamagetsi ikupitirirabe bwino, mapangidwe a kutsogolo ndi kumbuyo kwa magalimoto awiri amatha kulola galimoto kukhala ndi mphamvu zokwanira. Ndipo chifukwa magwero amphamvu a mawilo akutsogolo ndi akumbuyo ndi odziyimira pawokha, palibe chifukwa chopangira zida zovuta zotumizira ndi kugawa mphamvu.Kugawa mphamvu zowonjezereka kungathe kupezedwa kudzera mu kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka kayendetsedwe ka anthu.

Pamene magalimoto amphamvu atsopano akulowa m'mabanja ambiri, ubwino wa magetsi oyendetsa mawilo anayi, monga kuyendetsa bwino kwambiri, kusintha kosinthika, kuyankha mofulumira, komanso kuyendetsa bwino galimoto, amadziwika ndi anthu ambiri. Dual-motor smart-wheel drive imatengedwa kuti ndi imodzi mwazinthu zatsopano zamagalimoto amtsogolo. .

Pa LI L6, m'malo oyendetsa tsiku ndi tsiku monga misewu yakutawuni ndi misewu yayikulu komwe liwiro limakhala lokhazikika, ogwiritsa ntchito amatha kusankha "njira yamsewu" ndikusinthanso kuti akhale "chitonthozo / chokhazikika" kapena "masewera" mphamvu ngati pakufunika kuti akwaniritse Kusinthana pakati pa chitonthozo choyenera, chuma ndi magwiridwe antchito.

Mitundu yonse ya LI L6 ili ndi magalimoto oyendetsa mawilo anayi ngati muyezo. Ndi zothandiza bwanji pakuyendetsa tsiku ndi tsiku?

Kwa ma SUV apamwamba apakati mpaka akulu a kukula kofanana ndi LI L6, dual-motor intelligent four-wheel drive nthawi zambiri imapezeka pakati mpaka-high-end kasinthidwe, ndipo pamafunika makumi masauzande a yuan kuti akweze. Chifukwa chiyani LI L6 imaumirira pagalimoto yamawilo anayi ngati zida zokhazikika pamindandanda yonse?

Chifukwa pomanga magalimoto, Li Auto nthawi zonse imayika kufunikira kwa ogwiritsa ntchito mabanja patsogolo.

Pamsonkhano wotsegulira wa Li Li L6, Tang Jing, wachiwiri kwa purezidenti wa R&D wa Li Auto, adati: "Taphunziranso mtundu wa magudumu awiri, koma popeza nthawi yothamangira ya ma wheel drive awiri yatsala pang'ono masekondi 8, chofunikira kwambiri, kukhazikika pamisewu yovuta , sikunali kukwaniritsa zofunikira zathu, ndipo pamapeto tidasiya kuyendetsa popanda kukayikira."

Monga SUV yapamwamba mpaka yayikulu, LI L6 ili ndi ma mota apawiri kutsogolo ndi kumbuyo monga muyezo. Mphamvu yamagetsi imakhala ndi mphamvu zonse za 300 kilowatts ndi torque ya 529 N · m. Imathamanga makilomita 100 mu masekondi 5.4, amene ali patsogolo pa ntchito yabwino ya 3.0T magalimoto mwanaalirenji, koma Izi ndi chabe mzere wodutsa LI L6 wanzeru gudumu pagalimoto. Kuwonetsetsa kuti wogwiritsa ntchitoyo ndi banja lake ali otetezeka mumsewu uliwonse ndiye chigoli chabwino chomwe tikufuna kutsatira.

Pa LI L6, kuwonjezera pa misewu yayikulu, ogwiritsa ntchito alinso ndi mitundu itatu yamsewu yomwe angasankhe: njira yotsetsereka, misewu yoterera, ndi kuthawa kwapamsewu, zomwe zimatha kuphimba zochitika zambiri zoyendetsa misewu zomwe sizinapangidwe kwa ogwiritsa ntchito kunyumba.

Nthawi zonse, phula louma, phula labwino kapena konkriti limakhala ndi cholumikizira chachikulu kwambiri, ndipo magalimoto ambiri amatha kudutsa bwino. Komabe, mukamayang'anizana ndi misewu ina yopanda miyala kapena zovuta kwambiri komanso zovuta za misewu, monga mvula, matalala, matope, maenje ndi madzi, kuphatikiza ndi mapiri otsetsereka ndi kutsika, adhesion coefficient ndi yaying'ono, ndipo kukangana pakati pa mawilo ndi msewu kumachepa kwambiri, ndipo magudumu awiri oyendetsa galimoto amatha Ngati mawilo ena amapumira kapena kusuntha, magudumu ena amadutsa kapena kusayenda bwino. galimoto idzawululidwa.

Tanthauzo la SUV yapamwamba yamagudumu anayi ndikutha kutenga banja lonse bwino, motetezeka komanso momasuka m'misewu yosiyanasiyana yovuta.

Kanema woyeserera adawonetsedwa pamsonkhano wotsegulira wa LI L6. Li L6 yoyendetsa mawilo awiri ndi SUV yamagetsi yoyera inayerekeza kukwera mumsewu woterera wokhala ndi 20%, womwe ndi wofanana ndi msewu wotsetsereka wodekha wodziwika bwino mumvula ndi chipale chofewa. LI L6 mumayendedwe a "msewu woterera" idadutsa m'malo otsetsereka pang'onopang'ono, pomwe mtundu wamagalimoto awiri a SUV yamagetsi yamagetsi yotsetsereka molunjika potsetsereka.

Gawo lomwe silinawonetsedwe ndikuti timayika "zovuta" zambiri za LI L6 panthawi yoyesera - kuyerekezera misewu ya ayezi ndi matalala, misewu yoyera ya ayezi, ndikukwera m'misewu yamvula, matalala, ndi theka lamatope. Mu "njira yoterera", LI L6 idapambana mayeso. Chofunikira kwambiri kutchula ndichakuti LI L6 imatha kudutsa mtunda wa 10% wa ayezi weniweni.
"Izi mwachibadwa zimatsimikiziridwa ndi maonekedwe a thupi la magudumu anayi ndi magudumu awiri. Pansi pa mphamvu zomwezo, magalimoto oyendetsa magalimoto anayi amatha kugwira bwino komanso kukhazikika kuposa magalimoto awiri." adatero Jiage kuchokera ku gulu lowunika zinthu.

Kumpoto, kutentha kumakhala kotsika m’nyengo yachisanu, ndipo ngozi zapamsewu zobwera chifukwa cha misewu youndana ndi yoterera n’zofala. Pambuyo pa nyengo yozizira kum'mwera, madzi atawaza pamsewu, madzi oundana oundana adzapanga, kukhala ngozi yaikulu yobisika kwa chitetezo cha galimoto. Mosasamala kanthu za kumpoto kapena kum’mwera, nyengo yachisanu ikadzafika, ogwiritsira ntchito ambiri amayendetsa galimoto ali ndi mantha pamene ali ndi nkhaŵa: Kodi adzalephera kudziletsa ngati azembera pamsewu woterera?

Ngakhale anthu ena amati: Ziribe kanthu momwe gudumu la magudumu anayi liri labwino, ndi bwino kusintha matayala achisanu. Ndipotu, kumpoto chakumwera kwa Liaoning, chiwerengero cha ogwiritsa ntchito m'malo mwa matayala achisanu chatsika kwambiri, pamene eni ake ambiri am'madera akum'mwera adzagwiritsa ntchito matayala oyambirira a nyengo zonse ndikupita kukasintha magalimoto awo. Chifukwa mtengo wosinthira matayala ndi ndalama zosungirako umabweretsa mavuto ambiri kwa ogwiritsa ntchito.

Komabe, makina abwino oyendetsa magudumu anayi amatha kuonetsetsa kuti chitetezo chikuyenda bwino mumitundu yonse yamvula, matalala, ndi poterera. Kuti izi zitheke, tidayesanso kukhazikika kwa thupi la Li L6 panthawi yothamangitsa mizere yowongoka komanso kusintha kwadzidzidzi m'misewu yoterera.

The electronic stability system (ESP) ya thupi imagwira ntchito yofunika kwambiri ngati chitetezo chofunikira panthawiyi. LI L6 ikatembenukira panjira ya "msewu woterera", imatsetsereka, kuwongolera, ndi chiwongolero pothamanga panjira yoterera kapena kusintha njira yadzidzidzi. Zinthu zikachitika, ESP imatha kuzindikira m'nthawi yeniyeni kuti galimotoyo ili m'malo osakhazikika, ndipo nthawi yomweyo imawongolera momwe galimoto ikuthamangira komanso momwe thupi limayendera.

Makamaka, pamene galimotoyo ili pansi pa chiwongolero, ESP imawonjezera kupanikizika mkati mwa gudumu lakumbuyo ndikuchepetsa mphamvu yoyendetsa, potero kuchepetsa mlingo wa pansi pa chiwongolero ndikupangitsa kuti kufufuza kukhale kolimba; pamene galimoto ikuwomba, ESP imamanga mabuleki ku mawilo akunja kuti achepetse chiwongolero. Mochulukira, konzani njira yoyendetsera. Ntchito zovuta za machitidwewa zimachitika nthawi yomweyo, ndipo panthawiyi, dalaivala amangofunika kupereka njira.

Tawonanso kuti ngakhale ESP ikugwira ntchito, pali kusiyana kwakukulu pakukhazikika kwa ma SUV oyendetsa mawilo anayi ndi ma SUV awiri posintha misewu ndikuyamba misewu yoterera - LI L6 idakwera mwadzidzidzi mpaka liwiro la makilomita 90 pa ola molunjika. Itha kukhalabe yokhazikika yoyendetsa molunjika, matalikidwe a yaw ndi ochepa kwambiri posintha mayendedwe, ndipo thupi limasinthidwa mwachangu ndikuwongolera komwe likuyenda. Komabe, mtundu wa SUV yamagetsi yama wheel-wheelchair uli ndi kusakhazikika bwino komanso kutsatira, ndipo umafunika kuwongolera kangapo pamanja.

"Nthawi zambiri, bola ngati dalaivala sachita dala zinthu zoopsa, ndizosatheka kuti LI L6 iwonongeke."

Ogwiritsa ntchito mabanja ambiri omwe amakonda kuyenda pagalimoto akhala ndi chokumana nacho cha mawilo awo akumatira mu dzenje lamatope mumsewu wafumbi, zomwe zimafuna kuti wina azikankha ngolo kapena kuyimba kuti apulumutse anthu m'mphepete mwa msewu. Kusiya banja m’chipululu kulidi chikumbukiro chosapiririka. Pachifukwa ichi, magalimoto ambiri ali ndi "njira yopulumukira pamsewu", koma tinganene kuti "njira yopulumukirako" ndiyofunika kwambiri pokhapokha ngati pali magudumu anayi. Chifukwa "ngati matayala awiri akumbuyo a galimoto yoyendetsa kumbuyo agwera m'matope amatope nthawi imodzi, mosasamala kanthu kuti mutaponda molimba bwanji pa accelerator, matayala amangogwedezeka ndipo sangathe kugwira pansi."

Pa LI L6 yokhala ndi mayendedwe anzeru oyendetsa mawilo anayi, wogwiritsa ntchito akakumana ndi galimotoyo ikukakamira mumatope, matalala ndi malo ena ogwirira ntchito, ntchito ya "kuthawa pamsewu" imayatsidwa. Dongosolo lothandizira zamagetsi limatha kuzindikira kutsetsereka kwa magudumu munthawi yeniyeni komanso mwachangu komanso moyenera kuthana ndi gudumu loterera. Chitani ma braking control kuti mphamvu yoyendetsa galimoto isamutsidwe kumawilo a coaxial ndi adhesion, zomwe zimathandiza kuti galimotoyo ituluke bwino m'mavuto.

Pofuna kuthana ndi misewu yotsika yomwe magalimoto amakumana nawo m'malo ozungulira komanso malo owoneka bwino, LI L6 ilinso ndi "njira yotsetsereka".

Ogwiritsa ntchito amatha kuyika liwiro lagalimoto momasuka pamtunda wa makilomita 3-35. ESP ikalandira malangizowo, imasinthiratu kuthamanga kwa magudumu kuti galimotoyo itsike pa liwiro lokhazikika malinga ndi liwiro lomwe woyendetsa akufuna. Dalaivala safunikira kugwiritsa ntchito mphamvu kuwongolera liwiro lagalimoto, amangofunika kumvetsetsa komwe akulowera, ndipo amatha kusunga mphamvu zambiri kuti azitha kuwona momwe msewu uliri, magalimoto ndi oyenda pansi mbali zonse. Izi zimafuna kulondola kwadongosolo lapamwamba kwambiri.

Tikhoza kunena kuti popanda magudumu anayi, kuyenda ndi chitetezo cha SUV yapamwamba ndi nkhani zopanda pake, ndipo sizingapitirire patsogolo moyo wachimwemwe wa banja.

Woyambitsa Meituan Wang Xing adati pambuyo powulutsa msonkhano wa LI L6 woyambitsa: "Pali kuthekera kwakukulu kuti L6 ikhale chitsanzo chomwe antchito a Ideal amagula kwambiri."

Shao Hui, mainjiniya osiyanasiyana owongolera makina omwe adatenga nawo gawo pakupanga LI L6, akuganiza motere. Kaŵirikaŵiri amalingalira akuyenda ndi banja lake mu LI L6: “Ndine wogwiritsira ntchito L6 wamba, ndipo galimoto imene ndimafunikira iyenera kukhala yoyenerera mikhalidwe yambiri ya mseu.

Amakhulupirira kuti LI L6 yokhala ndi magudumu anayi anzeru ngati muyezo idzabweretsa phindu lenileni kwa ogwiritsa ntchito osati kungochita bwino, koma chofunikira kwambiri, chitetezo chapamwamba. Njira yanzeru yamagetsi yamagetsi ya LI L6 yamagetsi idzakhala ndi luso lotha kutuluka m'mavuto mukakumana ndi misewu yokwera ayezi ndi chipale chofewa komanso misewu yamatope yamatope kumidzi, kuthandiza ogwiritsa ntchito kupita kumalo ochulukirapo.

Kuwongolera kwanzeru "dual redundancy", kotetezeka kuposa kotetezeka

"Pamene mukupanga ma calibration osintha mzere wa LI L6, ngakhale pa liwiro lalikulu la makilomita 100 pa ola, muyezo wathu ndi kulamulira kayendedwe ka thupi mokhazikika, kugwirizanitsa kayendedwe ka ma axles kutsogolo ndi kumbuyo, ndi kuchepetsa chizolowezi cha kumbuyo kumbuyo kwa galimoto kugwedezeka. Zinali ngati galimoto yochita masewera olimbitsa thupi, "Yang anakumbukira, Yang, yemwe adayambitsa kulamulira kwamagetsi.

Monga momwe aliyense amamvera, kampani iliyonse yamagalimoto, ndipo ngakhale galimoto iliyonse, ili ndi kuthekera kosiyana ndi zokonda zamawonekedwe, kotero padzakhala zosinthana pakuwongolera magwiridwe antchito a magudumu anayi.

Maonekedwe a malonda a Li Auto amayang'ana kwambiri ogwiritsa ntchito kunyumba, ndipo mawonekedwe ake amawongolera nthawi zonse amaika chitetezo ndi kukhazikika patsogolo.

"Ziribe kanthu momwe zinthu zilili, tikufuna kuti dalaivala azidzidalira kwambiri panthawi yomwe akutembenuza chiwongolero. Tikufuna kuti nthawi zonse azimva kuti galimoto yake ndi yokhazikika komanso yotetezeka, ndipo sitikufuna kuti mamembala onse a m'banja omwe akukweramo achite mantha kapena achite mantha ndi galimotoyo. Pali nkhawa zokhudzana ndi chitetezo, "adatero Yang Yang.

LI L6 siiyika ogwiritsa ntchito kunyumba ngakhale pagalimoto yowopsa kwambiri, ndipo sitichita khama pakuika ndalama pantchito yachitetezo.

Kuphatikiza pa ESP, Li Auto yadzipangiranso "intelligent traction control algorithm" yomwe idayikidwa mu Li Auto's self-developed scalable multi-domain control unit, yomwe imagwira ntchito ndi ESP kuti ikwaniritse chitetezo chapawiri cha mapulogalamu owongolera ndi zida.

ESP yachikhalidwe ikalephera, makina owongolera anzeru amasinthira mwachangu ma torque agalimoto pomwe magudumu amayenda, amawongolera kuthamanga kwa magudumu mkati mwa malo otetezeka, ndikupereka mphamvu yoyendetsa kwambiri ndikuwonetsetsa kuti galimoto ili ndi chitetezo. Ngakhale ESP italephera, njira yoyendetsera bwino yowongolera imatha kugwira ntchito payokha kuti ipatse ogwiritsa ntchito chotchinga chachiwiri.

M'malo mwake, chiwopsezo cha kulephera kwa ESP sichokwera, koma chifukwa chiyani timalimbikira kuchita izi?

"Ngati kulephera kwa ESP kukuchitika, kudzakhala ndi vuto lalikulu kwa ogwiritsa ntchito kunyumba, kotero tikukhulupirira kuti ngakhale mwayi uli wochepa kwambiri, Li Auto idzaumirirabe kuyika ndalama za anthu ambiri ndi nthawi yofufuza ndi chitukuko kuti apatse ogwiritsa ntchito gawo lachiwiri la chitetezo cha 100%. Calibration Development Engineer GAI adatero.

Pamsonkhano woyambitsa Li Li L6, Tang Jing, wachiwiri kwa pulezidenti wa kafukufuku ndi chitukuko cha Li Auto, adati: "Mphamvu zazikulu za makina oyendetsa magudumu anayi, ngakhale zitagwiritsidwa ntchito kamodzi, ndizofunika kwambiri kwa ogwiritsa ntchito athu."

Monga tanenera poyamba, kuyendetsa magudumu anayi kuli ngati malo osungira omwe angagwiritsidwe ntchito mwachizolowezi, koma sangasiyidwe panthawi yovuta.
