Ni kangahe ifite ubwenge bwimodoka enye zifite ubwenge ziza zisanzwe kumurongo wa LI L6 kugirango ukoreshwe burimunsi?

Ikibazo gikunze kugaragara ku binyabiziga bigenda inyuma ni "gutembera", biterwa ninziga zinyuma zimena imipaka ntarengwa mbere yiziga ryimbere mugihe inguni, bigatuma ibiziga byinyuma binyerera, ni ukuvuga hejuru ya steer.

Mu buryo bw'igitekerezo, "kuzamuka no gutambuka" uburyo bwo gutwara ibiziga bine bifite gukurura no gufatana neza kuruta ibiziga bibiri, bifite ibinyabiziga bikoresha neza, kandi birashobora gutanga ubushobozi bwo kugenzura neza mumihanda inyerera cyangwa ibyondo. Kandi gushikama, kimwe nubushobozi bukomeye bwo gutambuka, birashobora kandi guteza imbere cyane umutekano wo gutwara, kandi nuburyo bwiza bwo gutwara imodoka.
Hamwe nogukomeza gukundwa kwimodoka zamashanyarazi nibinyabiziga bivangavanze, gutondekanya ibinyabiziga bine bigenda buhoro buhoro. LI L6 imaze gushyirwa ahagaragara, abayikoresha bamwe bari bafite amatsiko, niyihe modoka ya LI L6 ifite ibiziga bine?

Turashobora gukora ikigereranyo hamwe na bine yimodoka yimodoka ya lisansi. Ikinyabiziga gifite ibiziga bine kuri lisansi muri rusange kigabanyijemo igice-cy-ibinyabiziga bine-by-ibinyabiziga, amasaha yose-yimodoka-ine-na-bine-bigenda.

Igice Igihe 4WD irashobora kumvikana nk "" intoki zoherejwe "mumashanyarazi ane. Nyir'imodoka arashobora guca urubanza yigenga akurikije uko ibintu bimeze hanyuma akamenya ibinyabiziga bibiri cyangwa ibiziga bine mu gufungura cyangwa kuzimya urubanza rwo kwimura. Hindura.

Isaha-yuzuye yimodoka ine (All Wheel Drive) ifite centre itandukanye kandi yigenga igarukira-kunyerera itandukanya imbere ninyuma, ikwirakwiza imbaraga zo gutwara amapine ane muburyo runaka. Nkuko izina ribigaragaza, ibiziga bine birashobora gutanga imbaraga zo gutwara igihe icyo aricyo cyose no mubihe byose byakazi.

Igihe nyacyo 4WD irashobora guhita ihinduranya ibiziga bine mugihe bibaye ngombwa, mugihe ikomeza ibiziga bibiri mubindi bihe.

Mugihe cyibinyabiziga bine bikoresha ibinyabiziga bine, kubera ko isoko yingufu ari moteri gusa muri kabine yimbere, gukora uburyo butandukanye bwo gutwara no kugera ku gukwirakwiza umuriro hagati yimitambiko yimbere ninyuma bisaba ibikoresho byubukanishi bigoye, nkimbere ninyuma shafts no kwimura imanza. , ibyapa byinshi bifatanye hagati itandukanye, kandi ingamba zo kugenzura ziragoye. Mubisanzwe gusa moderi zohejuru cyangwa verisiyo yohejuru gusa ifite ibikoresho bine byimodoka.

Ibintu byarahindutse mugihe cyimodoka zikoresha amashanyarazi. Mugihe ikoranabuhanga ryibinyabiziga byamashanyarazi rikomeje gutera imbere, ubwubatsi bwimbere ninyuma yububiko bubiri bushobora kwemerera ikinyabiziga kugira imbaraga zihagije. Kandi kubera ko imbaraga zamashanyarazi yibiziga byimbere ninyuma byigenga, ntihakenewe ibikoresho bigoye byohereza no gukwirakwiza ibikoresho.Ikwirakwizwa ryinshi ryingufu zishobora kugerwaho hifashishijwe sisitemu yo kugenzura hakoreshejwe ikoranabuhanga, ntabwo iteza imbere imikorere yikinyabiziga gusa, ahubwo inemerera abakoresha benshi kwishimira korohereza ibiziga bine ku giciro gito.

Mugihe ibinyabiziga bishya byingufu byinjira mumiryango myinshi, ibyiza byo gutwara amashanyarazi afite moteri yibiziga bine, nkibikorwa byiza cyane, guhinduranya byoroshye, igisubizo cyihuse, hamwe nuburambe bwiza bwo gutwara, bizwi nabantu benshi. Ikinyabiziga gifite moteri ebyiri zifite ibiziga bine nacyo gifatwa nkimwe mubyerekezo bishya mumodoka zizaza. .

Kuri LI L6, ahantu hatwara ibinyabiziga bya buri munsi nkimihanda yo mumijyi ninzira nyabagendwa aho umuvuduko uhagaze neza, abakoresha barashobora guhitamo "uburyo bwumuhanda" hanyuma bakamenyera "imbaraga / zisanzwe" cyangwa "siporo" imbaraga zikenewe kugirango bagere kuri Guhinduranya hagati ihumure ryiza, ubukungu nigipimo cyimikorere.

Muburyo bwamashanyarazi "Ihumure / Bisanzwe", ingufu zimbere ninyuma zifata igipimo cyogukwirakwiza zahabu hamwe nogutezimbere byimazeyo gukoresha ingufu, zikunda guhumurizwa nubukungu, bidateye gutakaza ingufu no gutakaza lisansi n amashanyarazi. Muburyo bwimbaraga za "Siporo", igipimo cyiza cyingufu cyakoreshejwe kugirango ibinyabiziga bibone gukurura neza.

"Ikinyabiziga gifite ubwenge bune bwa LI L6 gisa nigihe cyose cyimodoka enye zimodoka zisanzwe zikoresha lisansi, ariko ubwenge bune bwibiziga bine bya LI L6 nabwo bufite" ubwonko "bwubwenge - urwego XCU rwagati umugenzuzi Ibikorwa nko guhindura uruziga rutunguranye, gukandagira cyane kuri moteri yihuta, kimwe nibipimo byimiterere yimodoka-nyayo byagaragajwe na sensor (nk'umuvuduko ukabije w'ikinyabiziga, umuvuduko wa yaw, inguni, n'ibindi). , mu buryo bwikora uhindure igisubizo cyiza cyo gusohora ibisubizo byiziga byimbere ninyuma, hanyuma hamwe na moteri ebyiri hamwe nubugenzuzi bwa elegitoronike, moteri yimodoka ine irashobora guhindurwa no gukwirakwizwa byoroshye kandi neza mugihe nyacyo ", ibi bikaba byavuzwe na injeniyeri ushinzwe iterambere rya kalibrasi GAI.

Ndetse no muri ubu buryo bubiri bwingufu, ibipimo bine byamashanyarazi ya LI L6 birashobora guhinduka mugihe icyo aricyo cyose binyuze muri algorithm yakozwe na software yonyine, bikarushaho kuzirikana ibinyabiziga bigenda, imbaraga, ubukungu numutekano.

Urukurikirane rwa LI L6 rufite ibikoresho byubwenge bine byimodoka nkibisanzwe. Ningirakamaro ki gutwara buri munsi?

Kuri SUVs zo hagati nini nini nini zingana na LI L6, moteri ebyiri zifite ubwenge bwimodoka enye zifite ibinyabiziga bisanzwe biboneka gusa muburyo bwo hagati-hejuru-hejuru, kandi bisaba ibihumbi icumi byamafaranga yo kuzamura. Kuki LI L6 ishimangira gutwara ibiziga bine nkibikoresho bisanzwe murukurikirane?

Kuberako iyo wubaka imodoka, Li Auto burigihe ishyira agaciro kubakoresha umuryango mbere.

Mu nama yo gutangiza Li Li L6, Tang Jing, visi perezida wa R&D wa Li Auto, yagize ati: “Twize kandi verisiyo y’ibinyabiziga bibiri, ariko kuva igihe cyo kwihuta cy’imodoka ebyiri zigera ku masegonda 8 , icy'ingenzi kurushaho, ni uko umutekano uhagaze ku mihanda igoye, ntibyari byujuje ibyo dusabwa, kandi amaherezo twaretse gutwara ibiziga bibiri nta gushidikanya. ”

Nka SUV nziza cyane hagati-nini nini, LI L6 ifite moteri ebyiri imbere ninyuma nkibisanzwe. Sisitemu y'amashanyarazi ifite ingufu za kilowatt 300 zose hamwe n'umuriro wa 529 N · m. Yihuta kugera kuri kilometero 100 mumasegonda 5.4, iri imbere yimikorere myiza yimodoka nziza ya 3.0T, ariko Uyu niwo murongo unyura kuri LI L6 ifite ubwenge bwimodoka enye. Ibyiza kurinda umutekano wumukoresha numuryango we mubihe byose byumuhanda n amanota meza dushaka gukurikirana.

Kuri LI L6, usibye uburyo bwimihanda, abayikoresha nabo bafite uburyo butatu bwo guhitamo kugirango bahitemo: uburyo bwimisozi ihanamye, umuhanda unyerera, hamwe no guhunga umuhanda, bishobora ahanini gukwirakwiza ibintu byinshi bidafite umuhanda wa kaburimbo kubakoresha urugo.

Mubihe bisanzwe, byumye, asfalt nziza cyangwa kaburimbo ya beto ifite coefficient nini cyane, kandi ibinyabiziga byinshi birashobora kugenda neza. Nyamara, iyo uhuye ninzira zimwe zidafite kaburimbo cyangwa imiterere yumuhanda igoye kandi ikaze, nkimvura, shelegi, ibyondo, ibinogo namazi, bifatanije nubutumburuke no kumanuka, coefficient ya adhesion iba nto, kandi guterana hagati yibiziga na umuhanda uragabanutse cyane, kandi ibinyabiziga bifite ibiziga bibiri birashobora Niba ibiziga bimwe byanyerera cyangwa bizunguruka, cyangwa bigahagarara ahantu kandi ntibishobora kugenda, inzira nziza yikinyabiziga gifite ibiziga bine bizamenyekana.

Ibisobanuro bya SUV nziza yimodoka enye ni ugushobora gutwara umuryango wose neza, umutekano kandi neza unyuze mumihanda itandukanye igoye.

ishusho
Video yikizamini yerekanwe mu nama yo gutangiza LI L6. Imodoka ifite ibiziga bibiri bya LI L6 hamwe na SUV yumuriro wamashanyarazi bigereranya kuzamuka kumuhanda unyerera hamwe na gradient ya 20%, ibyo bikaba bihwanye numuhanda woroheje umenyereye mumvura nimvura. LI L6 muburyo bwa "umuhanda unyerera" yanyuze ahantu hahanamye gahoro gahoro, mugihe verisiyo yimodoka ebyiri yimodoka ya SUV yamashanyarazi yatembye yamanutse kumurongo.

Igice kiterekanwa ni uko dushiraho "ingorane" nyinshi kuri LI L6 mugihe cyibizamini - kwigana umuhanda wa barafu na shelegi, umuhanda wa barafu, no kuzamuka kumihanda yimvura, urubura, nigice cyondo cyuzuye ibyondo. Muburyo bwa "kunyerera", LI L6 yatsinze ikizamini neza. Igikwiye kuvugwa cyane ni uko LI L6 ishobora kunyura hejuru ya 10% ya barafu.
"Ibi bisanzwe bigenwa n'ibiranga umubiri biranga ibiziga bine na moteri ebyiri. Ku mbaraga zimwe, ibinyabiziga bine bifite ibiziga bine bifata neza kandi bigahagarara neza kuruta ibinyabiziga bifite ibiziga bibiri." ati Jiage wo mu itsinda rishinzwe gusuzuma ibicuruzwa.

Mu majyaruguru, ubushyuhe buri hasi mu gihe cy'itumba, kandi impanuka zo mu muhanda zatewe n'imihanda ya barafu kandi iranyerera. Nyuma y'itumba mu majyepfo, amazi amaze kuminjagira mumuhanda, hazaba urubura ruto cyane, bikabera akaga gakomeye guhungabanya umutekano w’ibinyabiziga. Tutitaye ku majyaruguru cyangwa mu majyepfo, iyo igihe cy'itumba kije, abakoresha benshi batwara bafite ubwoba mu gihe bahangayitse: Bazabura ubuyobozi nibanyerera mu muhanda unyerera?

Nubwo abantu bamwe bavuga ngo: Nubwo ibinyabiziga bine bigenda neza, nibyiza gusimbuza amapine yimbeho. Mubyukuri, mukarere ka majyaruguru mumajyepfo ya Liaoning, umubare wabakoresha basimbuza amapine yimvura wagabanutse cyane, mugihe umubare munini wabatunze imodoka mukarere ka majyepfo bazakoresha amapine yumwimerere ibihe byose bakajya gusimbuza imodoka zabo. Kuberako ikiguzi cyo gusimbuza amapine nigiciro cyo kubika bizana ibibazo byinshi kubakoresha.

Nyamara, sisitemu nziza yo gutwara ibiziga bine irashobora kurushaho kurinda umutekano wo gutwara ibinyabiziga ubwoko bwimvura, urubura, nuburyo umuhanda unyerera. Kugira ngo ibyo bishoboke, twagerageje kandi guhagarara kwa Li L6 mugihe cyo kwihuta kumurongo ugororotse hamwe nimpinduka zihutirwa kumuhanda unyerera.

Sisitemu yo gutuza ya elegitoronike (ESP) yumubiri igira uruhare runini nkinzitizi yumutekano ikenewe muri iki gihe. Nyuma yuko LI L6 ifunguye uburyo bwa "umuhanda unyerera", izanyerera, hejuru ya steer, no munsi ya steer iyo yihuta kumuhanda unyerera cyangwa guhindura inzira yihutirwa. Iyo ibintu bibaye, ESP irashobora kumenya mugihe nyacyo ko ikinyabiziga kimeze nabi, kandi kizahita gikosora icyerekezo cyimodoka nikigenda cyumubiri.

By'umwihariko, iyo ikinyabiziga kiri munsi yubuyobozi, ESP yongera umuvuduko wimbere yimbere kandi ikagabanya umuvuduko wo gutwara, bityo bikagabanya urwego rwo munsi ya steer kandi bigatuma gukurikirana bikomera; iyo ikinyabiziga hejuru yubuyobozi, ESP ikoresha feri kumuziga yo hanze kugirango igabanye kuyobora. Birakabije, ikosore icyerekezo cyo gutwara. Ibikorwa bigoye bya sisitemu bibaho mugihe gito, kandi muriki gikorwa, umushoferi akeneye gutanga icyerekezo gusa.

Twabonye kandi ko na hamwe na ESP ikora, hari itandukaniro rinini mumitekerereze yimodoka yimodoka enye na SUV zifite ibiziga bibiri mugihe uhinduye inzira ugatangirira mumihanda inyerera - LI L6 yahise yihuta kugera kumuvuduko wa kilometero 90 kuri isaha mu murongo ugororotse. Irashobora gukomeza kugumya kugororoka kugororotse kugororotse, yaw amplitude nayo ni nto cyane mugihe uhinduye inzira, kandi umubiri urihuta kandi neza ugasubira inyuma ugana icyerekezo. Nyamara, ibinyabiziga bibiri byimodoka ya SUV yumuriro wamashanyarazi bifite umutekano muke no gukurikirana, kandi bisaba gukosorwa nintoki nyinshi.

"Muri rusange, igihe cyose umushoferi adakoze nkana ibikorwa biteje akaga, ntibishoboka ko LI L6 itakaza ubuyobozi."

Abakoresha benshi mumiryango bakunda gutembera mumodoka bafite uburambe bwo gutuma ibiziga byabo bigwa mu cyobo cyondo kumuhanda wa kaburimbo, bisaba umuntu gusunika igare cyangwa no guhamagarira gutabara kumuhanda. Gusiga umuryango mubutayu mubyukuri nibuka. Kubera iyo mpamvu, imodoka nyinshi zifite uburyo bwa "guhunga umuhanda", ariko twavuga ko uburyo bwo "guhunga umuhanda" bufite agaciro gusa hashingiwe ku gutwara ibiziga bine. Kuberako "niba amapine abiri yinyuma yimodoka yinyuma yinyuma yaguye icyarimwe icyarimwe, nubwo wakandagira ute kuri moteri yihuta, amapine azanyerera gusa kandi ntashobora gufata hasi na gato."

Kuri LI L6 ifite ibikoresho bisanzwe byubwenge buke buke, mugihe uyikoresha ahuye nikinyabiziga cyaguye mubyondo, shelegi nibindi bikorwa byakazi, imikorere "guhunga umuhanda" irakingurwa. Sisitemu yo gufasha muburyo bwa elegitoronike irashobora kumenya kunyerera mugihe nyacyo kandi byihuse kandi neza guhangana nuruziga. Kora feri kugirango feri yikinyabiziga yimurwe mumuziga ya coaxial ifatanye, ifasha ikinyabiziga kwikuramo ibibazo neza.

Mu rwego rwo guhangana n’imihanda yamanuka ibinyabiziga bizahura nabyo mu nkengero n’ahantu nyaburanga, LI L6 nayo ifite "uburyo butumburutse".

Abakoresha barashobora gushiraho ubwisanzure bwikinyabiziga mubirometero 3-35. ESP imaze kwakira amabwiriza, ihindura byimazeyo umuvuduko wuruziga kugirango ibinyabiziga bimanuka kumuvuduko uhoraho ukurikije umuvuduko wumushoferi. Umushoferi ntakeneye gukoresha ingufu agenzura umuvuduko wikinyabiziga, akeneye gusa kumenya icyerekezo, kandi arashobora kuzigama ingufu nyinshi kugirango yitegereze uko umuhanda umeze, ibinyabiziga nabanyamaguru kumpande zombi. Iyi mikorere isaba sisitemu yo hejuru cyane kugenzura neza.

Turashobora kuvuga ko udafite ibiziga bine, kunyura hamwe numutekano wumutekano wa SUV nziza ni ibiganiro byubusa, kandi ntibishobora gukomeza ubuzima bwumuryango.

Wang Xing washinze Meituan, nyuma yo gutangaza imbonankubone mu nama yo gutangiza LI L6 yagize ati: "Birashoboka cyane ko L6 izaba icyitegererezo abakozi ba Ideal bagura cyane."

Shao Hui, urwego rwimikorere ya sisitemu yo kugenzura ibikorwa byagize uruhare mu iterambere rya LI L6, atekereza gutya. Akenshi atekereza gutembera hamwe numuryango we muri LI L6: “Ndi umukoresha wa L6 usanzwe, kandi imodoka nkeneye igomba kuba ibereye mumihanda myinshi. Mubihe byose, njye n'umuryango wanjye dushobora gutera imbere tugatsinda neza. Niba umugore wanjye n'abana bahatiwe kugenda mu muhanda, nzumva nicira urubanza. ”

Yizera ko LI L6 ifite ibikoresho by’ubwenge bine bifite ubwenge nkibisanzwe bizazana agaciro nyako kubakoresha mu bijyanye n’imikorere myiza gusa, ariko cyane cyane, urwego rwo hejuru rw’umutekano. Sisitemu yo mu bwoko bwa LI L6 ifite amashanyarazi afite ibiziga bine bizagira ubushobozi bwiza bwo kwikuramo ibibazo mugihe ihuye n’umuhanda uzamuka urubura na shelegi hamwe n’imihanda ya kaburimbo yuzuye ibyondo mu cyaro, ifasha abayikoresha kujya ahantu henshi.

Igenzura ryubwenge ryubwenge "dual redundancy", umutekano kuruta umutekano

"Iyo dukora umurongo uhindura kalibrasi ya LI L6, ndetse no ku muvuduko mwinshi wa kilometero 100 mu isaha, igipimo cyacu ni ukugenzura imikorere yumubiri neza, guhuza imigendere yimbere yimbere ninyuma, no kugabanya imyumvire ya impera yinyuma yimodoka kunyerera. Byari bimeze nk'imodoka ikora siporo, ”Yang Yang, wateje imbere uburyo bwo kugenzura ibikoresho bya elegitoroniki ya chassis.

Nkuko buriwese yabyunvise, buri sosiyete yimodoka, ndetse na buri modoka, ifite ubushobozi butandukanye nuburyo bukunda, kuburyo byanze bikunze hazabaho gucuruza mugihe uhindura imikorere yimodoka enye.

Ibicuruzwa bya Li Auto byibanda kubakoresha murugo, kandi imikorere ya Calibration yerekanwe buri gihe ishyira umutekano numutekano imbere.

"Uko ikibazo cyaba kimeze kose, turashaka ko umushoferi yumva afite icyizere cyane mu gihe ahinduye ikizunguruka. Turashaka ko ahora yumva ko imodoka ye ihagaze neza kandi ifite umutekano, kandi ntidushaka ko hagira n'umwe mu bagize umuryango ugenda. kumva ubwoba cyangwa kugira ubwoba bw'imodoka. Hari impungenge z'umutekano ", Yang Yang.

LI L6 ntabwo izashyira abakoresha murugo no mubihe byoroheje byo gutwara ibinyabiziga, kandi ntidutanga imbaraga zo gushora mubikorwa byumutekano.

Usibye ESP, Li Auto yanateje imbere "ubwenge bwogukurikirana bwubwenge algorithm" yoherejwe muri Li Auto yikorera ubwayo yapimye cyane igizwe na domaine igenzura, ikorana na ESP kugirango igere ku mutekano muke wibikoresho bya software hamwe nibikoresho.

Iyo gakondo ya ESP yananiwe, sisitemu yo kugenzura gukurura ubwenge ihindura byimazeyo itara risohoka rya moteri mugihe ibiziga byanyerera, bikagenzura igipimo cyo kunyerera cyumuzingi ahantu hizewe, kandi bigatanga imbaraga nini zo gutwara mugihe umutekano wibinyabiziga. Nubwo ESP yananiwe, kugenzura ubwenge gukurura algorithm irashobora gukora yigenga kugirango itange abakoresha inzitizi yumutekano wa kabiri.

Mubyukuri, igipimo cyo gutsindwa kwa ESP ntabwo kiri hejuru, ariko kuki dushimangira kubikora?

"Niba gutsindwa kwa ESP bibaye, bizagira ingaruka zikomeye ku bakoresha urugo, bityo rero twizera ko nubwo bishoboka ari bike cyane, Li Auto izakomeza gutsimbarara ku gushora imari ku bantu benshi n'umwanya mu bushakashatsi no mu iterambere kugira ngo abakoresha babone urwego rwa kabiri rw'umutekano 100%. " Calibration Development Engineer GAI yavuze.

Mu nama yatangije Li Li L6, Tang Jing, visi perezida w’ubushakashatsi n’iterambere rya Li Auto, yagize ati: "Ubushobozi bw’ibanze bwa sisitemu yo gutwara ibiziga bine, kabone niyo byakoreshwa rimwe gusa, bifite agaciro gakomeye ku bakoresha bacu."

Nkuko byavuzwe mu ntangiriro, ibiziga bine ni nkibigega bishobora gukoreshwa bisanzwe, ariko ntibishobora gusigara mugihe gikomeye.
