Kune yepakati-kusvika-hombe yemhando yepamusoro SUVs akaenzana neLI L6, dual-motor yakangwara ina-mavhiri dhiraivha inongowanikwa chete pakati-kusvika-yepamusoro-yekupedzisira masisitimu, uye inoda makumi ezviuru zveyuan kuti ikwidziridze.Nei LI L6 ichisimbirira pane mana-mavhiri dhiraivha seyakajairwa midziyo yeese akatevedzana?

Nekuti pakuvaka mota, Li Auto inogara ichiisa kukosha kwevashandisi vemhuri pamberi.

Pamusangano wekuvhurwa kweLi Li L6, Tang Jing, mutevedzeri wemutungamiri weR&D weLi Auto, akati: “Takadzidza zvakare vhezheni yemavhiri maviri, asi kubva panguva yekukwidziridzwa kweiyo maviri-vhiri drive vhezheni yave pedyo nemasekonzi masere. , zvinotokosha zvikuru, kugadzikana kwemigwagwa yakaoma kunzwisisa , kwakanga kuri kure nokusvitsa zvatinoda, uye pakupedzisira takarega kudhiraivha mavhiri maviri pasina kuzengurira.”

Seyoumbozha yepakati-kusvika-hombe SUV, iyo LI L6 ine mbiri mbiri kumberi uye kumashure mota seyakajairwa.Simba remagetsi rine simba rose re 300 kilowatts uye torque yose ye529 N · m.Inomhanyisa kusvika kumakiromita zana mumasekondi 5.4, iri pamberi pekuita kwakanaka kwemotokari dzemhando yepamusoro 3.0T, asi Iyi ingori mutsetse wekupfuura weLI L6 yakangwara mana-mavhiri dhiraivha.Zvirinani kuve nechokwadi chekuchengetedzwa kwemushandisi nemhuri yake mumamiriro ese emugwagwa ndicho chibodzwa chakakwana chatinoda kutevera.

PaLI L6, pamusoro penzira yemugwagwa, vashandisi vanewo nzira nhatu dzemumugwagwa dzekusarudza kubva: dzakatenuka modhi, mugwagwa unotsvedza, uye kupukunyuka-mumugwagwa, izvo zvinogona kuvharidzira akawanda asina kugadzirwa migwagwa yekutyaira yevashandisi vekumba.

Mumamiriro ezvinhu akajairwa, yakaoma, yakanaka asphalt kana kongiri pavement ine yakakura adhesion coefficient, uye mota zhinji dzinogona kupfuura zvakanaka.Zvisinei, kana takatarisana nemimwe migwagwa isina tara kana zvimwe zvakaoma uye zvakaoma migwagwa, zvakadai semvura, sinou, madhaka, makomba nemvura, zvakasanganiswa nekukwira nekudzika kwemateru, coefficient yekunamatira idiki, uye kupokana pakati pemavhiri uye. mugwagwa wakadzikisira zvikuru, uye motokari inotyaira mavhiri maviri inogona Kana mamwe mavhiri akatsvedza kana kutenderera, kana kuti akamira panzvimbo uye asingakwanisi kufamba, kupfuvura kuri nani kwemotokari ine mavhiri mana kucharatidzwa.

Zvinoreva zveumbozha mana-mavhiri drive SUV ndiko kukwanisa kutora mhuri yese zvakanaka, zvakachengeteka uye zvakanaka kuburikidza nemigwagwa yakasiyana yakaoma.

mufananidzo
Vhidhiyo yekuyedza yakaratidzwa pamusangano wekuvhurwa kweLI L6.Iyo mavhiri maviri-mavhiri vhezheni yeLI L6 uye imwe yakachena yemagetsi SUV yakateedzera kukwira munzira inotsvedza ine gradient ye20%, iyo yakaenzana neyakajairwa yakapfava yakapfava mugwagwa mukunaya kwemvura nechando.Iyo LI L6 mu "nzira inotsvedza" modhi yakapfuura nepamateru zvinyoro zvishoma, ukuwo maviri-mavhiri dhiraivha yeakachena yemagetsi SUV yakatsvedza yakananga pasi pamateru.

Chikamu chisina kuratidzwa ndechekuti isu tinoisa mamwe "zvinetso" zveLI L6 panguva yekuyedza - kutevedzera migwagwa yechando nechando, nzira dzechando dzakachena, uye kukwira hafu yekunaya, chando, uye hafu yemigwagwa ine madhaka.Mu "nzira inotsvedza" modhi, iyo LI L6 yakabudirira bvunzo.Chinonyanya kukosha kutaurwa ndechekuti LI L6 inogona kupfuura 10% mutsetse wechando chakachena.
"Izvi zvinogara zvichitariswa nemaitiro emuviri ekutyaira mavhiri mana uye maviri-mavhiri maviri. Pasi pesimba rimwe chete, mavhiri mana-mavhiri anotyaira ari nani uye akadzikama pane maviri-mavhiri."akadaro Jiage kubva kuchikwata chekuongorora chigadzirwa.

Kuchamhembe, tembiricha inodzikira muchando, uye tsaona dzemotokari dzinokonzerwa nemigwagwa ine aizi uye inotsvedza yakajairika.Mushure menguva yechando kumaodzanyemba, kana mvura yasaswa mumugwagwa, chando chakatetepa chinoumbwa, chikava njodzi huru yakavanzwa kukuchengetedzwa kwemotokari.Pasinei nekuchamhembe kana kumaodzanyemba, kana chando chasvika, vashandisi vazhinji vanotyaira vachitya vachinetseka: Vachatadza kuzvidzora here kana vakatsvedza munzira inotsvedza?

Kunyangwe vamwe vanhu vachiti: Hazvina mhosva kuti mavhiri mana akanaka sei, zviri nani kutsiva matai echando.Muchokwadi, mudunhu rekuchamhembe kumaodzanyemba kweLiaoning, chikamu chevashandisi vanotsiva matai echando chadzikira zvakanyanya, nepo ruzhinji rwevaridzi vemotokari mudunhu rekumaodzanyemba vachashandisa matai ekutanga-mwaka wose voenda kunotsiva mota dzavo.Nekuti mutengo wekutsiva matayi uye mutengo wekuchengetedza unounza dambudziko rakawanda kune vashandisi.

Nekudaro, yakanaka mana-mavhiri dhiraivha system inogona kuve nechokwadi chekutyaira chengetedzo mumhando dzese dzemvura, sinou, uye mumigwagwa inotsvedza.Kuti izvi zviitike, isu takaedzawo kugadzikana kwemuviri weLi L6 panguva yakatwasuka-mutsara kukwirisa uye nekukurumidzira nzira yekuchinja mumigwagwa inotsvedza.

Iyo yemagetsi kugadzikana system (ESP) yemuviri inoita basa rakakosha sechinhu chinodiwa chekuchengetedza chipingamupinyi panguva ino.Mushure mekunge LI L6 yatendeuka pa "nzira inotsvedza" modhi, inotsvedza, pamusoro peiyo, uye pasi pemutsetse kana ichimhanyisa munzira inotsvedza kana kuita shanduko yekukurumidza.Kana mamiriro ezvinhu aitika, ESP inogona kuona munguva chaiyo kuti motokari iri mumamiriro asina kugadzikana, uye inobva yagadzirisa mafambiro emotokari uye chimiro chemuviri.

Kunyanya, kana mota iri pasi pemadhiraivha, ESP inowedzera kudzvanywa mukati vhiri rekumashure uye inoderedza torque yekutyaira, nekudaro ichidzikisa dhigirii repasi pedhiraivha uye kuita yekutevera kusimba;kana motokari ichidarika madhiraivha, ESP inoshandisa mabhureki kumavhiri ekunze kuderedza chidhiraivho.Zvakawandisa, gadzirisa nzira yekutyaira.Aya maitiro akaomarara ehurongwa anoitika nekukasira, uye panguva iyi, mutyairi anongoda kupa mafambiro.

Takaona zvakare kuti kunyangwe neESP ichishanda, pane musiyano mukuru mukudzikama kwemavhiri mana uye maviri-mavhiri SUVs pakuchinja nzira nekutanga mumigwagwa inotsvedza - iyo LI L6 yakangoerekana yawedzera kumhanya kwemakiromita makumi mapfumbamwe awa mumutsara wakatwasuka.Iyo inogona kuramba yakagadzikana yakatwasuka-mutsetse kutyaira, iyo yaw amplitude zvakare idiki kwazvo kana uchichinja nzira, uye muviri unokurumidza uye mushe kudzoserwa kunzira yekutyaira.Nekudaro, iyo maviri-mavhiri dhiraivha vhezheni yeakachena yemagetsi SUV haina kugadzikana uye yekutevera, uye inoda akawanda manyore ekugadzirisa.

"Kazhinji kutaura, chero mutyairi asingaite nemaune zviito zvine njodzi, hazvigoneke kuti LI L6 irase kutonga."

Vazhinji vashandisi vemhuri vanoda kufamba nemotokari vakava noruzivo rwokuti mavhiri avo akanamira mugomba revhu mumugwagwa usina tsvina, kuchida kuti mumwe munhu asundire ngoro kana kuti kunyange kudanidzira nokuda kwokununurwa parutivi pomugwagwa.Kusiya mhuri murenje chaizvoizvo chiyeuchidzo chisingatsungiririki.Nokuda kwechikonzero ichi, motokari dzakawanda dzakagadzirirwa "off-road escape" mode, asi zvinogona kutaurwa kuti "off-road escape" mode inonyanya kukosha pasi pechikonzero chechina-wheel drive.Nokuti "kana matai maviri ekumashure emotokari inofamba nemavhiri akawira mumatope panguva imwe chete, zvisinei kuti ukatsika zvakasimba sei paaccelerator, matai acho anongosvetuka-svetuka asingatombogoni kubata pasi."

PaLI L6 yakashongedzwa neyakajairwa yakangwara mana-mavhiri dhiraivha, kana mushandisi asangana nemotokari ichinamira mumadhaka, sinou uye mamwe mamiriro ekushanda, "off-road kutiza" basa rinobatidzwa.Iyo yemagetsi yekubatsira sisitimu inogona kuona kutsvedza kwevhiri munguva chaiyo uye nekukurumidza uye nemazvo kubata nevhiri rinotsvedza.Ita mabhureki ekudzora kuti simba rekutyaira riendeswe kumavhiri ecoaxial ane adhesion, zvichibatsira mota kubuda mudambudziko zvakanaka.

Kuti ugone kurarama nemigwagwa yekudzika iyo mota dzichasangana munzvimbo dzepasi uye nzvimbo dzinoyevedza, iyo LI L6 zvakare ine "materu maitiro".

Vashandisi vanogona kuseta zvakasununguka kumhanya kwemotokari mukati mehupamhi hwemakiromita 3-35.Mushure mekunge ESP yagamuchira rairo, inoshingaira kugadzirisa vhiri rekupedzisira kuti motokari iende pasi nekumhanya inogara ichienderana nemutyairi anodikanwa kumhanya.Mutyairi haafanire kushandisa simba kudzora kumhanya kwemotokari, anongoda kubata kutungamira, uye anogona kuchengetedza simba rakawanda kuti aone mamiriro emugwagwa, mota uye vanofamba netsoka kumativi ese.Iri basa rinoda yakanyanya kukwirira hurongwa hwekutonga.

Zvinogona kutaurwa kuti pasina mavhiri mana, kupfuura uye pfungwa yekuchengeteka kweSUV yeumbozha kutaura kusina maturo, uye haigoni kutakura upenyu hunofadza hwemhuri zvishoma nezvishoma.

Muvambi weMeituan Wang Xing akati mushure mekutepfenyurwa kwemusangano wekuvhurwa kweLI L6: "Pane mukana wakakura wekuti L6 ndiyo ichange iri modhi inotengwa nevashandi veIdeal."

Shao Hui, anotambanudzira kudzora system injinjini akatora chikamu mukuvandudzwa kweLI L6, anofunga nenzira iyi.Anowanzo fungidzira achifamba nemhuri yake muLI L6: “Ini ndiri mushandisi weL6, uye mota yandinoda inofanira kunge yakakodzera kune mazhinji emigwagwa mamiriro.Mumamiriro ezvinhu ose, ini nemhuri yangu tinokwanisa kufambira mberi uye tipasa zvakanaka.Kana mudzimai wangu nevana vakamanikidzwa kubuda mumugwagwa, ndinonzwa ndine mhosva zvikuru.”

Anotenda kuti LI L6 yakashongedzerwa nehungwaru ina-mavhiri dhiraivha seyakajairwa ichaunza kukosha chaiko kune vashandisi maererano kwete chete kuita kuri nani, asi zvakanyanya kukosha, mwero wepamusoro wekuchengetedza.Iyo LI L6's intelligent electric four-wheel drive system ichave nekwaniso iri nani yekubuda mudambudziko kana yatarisana nemigwagwa yechando nechando inokwira nemigwagwa ine madhaka yemavhu kumaruwa, ichibatsira vashandisi kuenda kune dzimwe nzvimbo.

Intelligent traction control "dual redundancy", yakachengeteka pane yakachengeteka

"Kana tichiita mitsara-yekuchinja calibration yeLI L6, kunyangwe nekumhanya kwakanyanya kwemakiromita zana paawa, chiyero chedu ndechekudzora kufamba kwemuviri zvakatsiga, kuronga mafambiro emberi nekumashure maekisi, uye kuderedza maitiro eiyo. kumashure kwemota kutsvedza.Yakanga yakaita semotokari yemitambo yemitambo, "Yang Yang, akagadzira chassis yemagetsi control yekubatanidza, akayeuka.

Sekunzwa kwakaita munhu wese, kambani yega yega yemota, uye kunyangwe mota yega yega, ine hunyanzvi hwakasiyana uye masitaera zvaunofarira, saka pachange paine kutengeserana-offs kana calibrating four-wheel drive performance.

Li Auto's chigadzirwa chinzvimbo chinotarisa kune vashandisi vemba, uye maitiro ayo ekugadzirisa maitiro anogara achiisa kuchengetedzeka uye kugadzikana pekutanga.

"Hazvinei nekuti mamiriro akaita sei, tinoda kuti mutyairi anzwe aine chivimbo chakanyanya paanotenderedza vhiri. Tinoda kuti agare achinzwa kuti motokari yake yakagadzikana uye yakachengeteka, uye hatidi chero nhengo dzemhuri dzinokwira. Kutya kana kutya mota Pane kutyira nezvekuchengetedza, "Yang Yang akadaro.

LI L6 haizoise vashandisi vepamba kunyangwe idiki ine njodzi yekutyaira mamiriro, uye isu tinosara nekuedza mukudyara mukuchengetedza basa.

Pamusoro peESP, Li Auto yakazvigadzirawo "yakangwara traction control algorithm" yakaiswa muLi Auto's self-developed scalable multi-domain control unit, iyo inoshanda neESP kuwana huviri kuchengetedza redundancy ye controller software uye hardware.

Kana iyo yechinyakare ESP ikatadza, iyo yakangwara traction control system inoshingairira inoburitsa torque yemota kana mavhiri anotsvedza, inodzora vhiri rekutsvedza mukati menzvimbo yakachengeteka, uye inopa yakanyanya kutyaira simba uchivimbisa kuchengetedzwa kwemotokari.Kunyangwe ESP ikatadza, iyo yakangwara traction control algorithm inogona kushanda yakazvimiririra kupa vashandisi chechipiri chekuchengetedza chipingamupinyi.

Muchokwadi, mwero wekutadza kweESP hauna kukwirira, asi nei tichisimbirira kuita izvi?

"Kana kutadza kweESP kukaitika, kuchava nerufu rwevashandisi vekumba, saka tinotenda kuti kunyangwe mukana wacho uri mudiki, Li Auto icharamba ichisimbirira kuisa vanhu vazhinji uye nguva mukutsvaga nekusimudzira kupa vashandisi ruzivo. chikamu chechipiri che100% chengetedzo."Calibration Development Engineer GAI akadaro.

Pamusangano wekutanga weLi Li L6, Tang Jing, mutevedzeri wemutungamiri wezvekutsvagisa nekusimudzira Li Auto, akati: "Kugona kwakakosha kweiyo mana-vhiri drive system, kunyangwe ikangoshandiswa kamwe chete, yakakosha zvikuru kune vashandisi vedu."

Sezvambotaurwa pakutanga, dhiraivha ine mavhiri mana yakafanana nenzvimbo inochengeterwa inogona kushandiswa kazhinji, asi haigone kusiiwa panguva dzakaoma.
